The best air fryers could completely change your food preparation. Air fryers need a lot less oil than you'd use for regular frying, which means you'll get healthier food that's just as delicious, and because they're much smaller than standard ovens they heat up quicker and cook faster and more efficiently. So not only will you get your dinner much sooner, you'll save on energy bills too.

Air fryers don't actually fry food in the conventional sense. They're compact ovens that sit on your countertop and mimic the effects of frying with hot air and powerful fans that are large relative to the cooking space. Combined with designs that maximize airflow, they quickly deliver crisp and great-tasting results with not very much oil.

Our expert reviewers have tested dozens of of air fryers, from budget models with minimal options through to high-end smart models and dual-basket fryers that enable you to cook an entire meal in one go. They put them through standardized tests to gauge their performance on basic cooking, and also assess how easy they are to use and clean, and whether they offer good value for money. Based on those tests, we've rounded up what we think are the best air fryers for a range of needs and budgets.

For us the best air fryer overall is the Ninja Double Stack, thanks to its ability to cook two portions of food to perfection while taking up minimal counter space. Read on for our full list of recommendations based on our hands-on testing.

Specifications

Type: Basket fryer
Wattage: 2470W
Capacity: 10qt / 9.5L
Dimensions (HxWxD): 15.14 x 11.25 x 19.22" / 38.5 x 28 x 47cm
Weight: 23.15lbs / 10.3kg
Modes: 6

Reasons to buy

+
Small footprint, generous capacity
+
Extra trays for even more cooking space
+
Top-tier performance

Reasons to avoid

-
Expensive for a dual-basket model
-
'8-portion' capacity feels ambitious
-
Can't fit big foods whole
Buy it if:

✅ Space is at a premium: Its two-tier design means the Ninja Double Stack can cook far more food than other air fryers with the same footprint.
You want to cook several different foods at once: With two baskets and four trays, this air fryer is a great multi-tasker.

Don't buy it if:

You want to cook pizzas: The Double Stack's vertical arrangement means it's not best suited to large items of food.
❌ You want to cook wet foods: The fairly large holes at the back of the baskets make this a bad idea.

With most air fryers, the more generous the cooking capacity, the more counter space you'll need to sacrifice. This Ninja model cleverly avoids that issue by stacking its baskets one on top of the other, rather than side-by-side. It's such a smart design, we gave it the prize for Best Air Fryer in the 2024 TechRadar Choice Awards. Each drawer holds 5qts / 4.75L, and you can create even more cooking space by slotting in one of the provided trays. Although do note that the tall-rather-than-wide approach means you won't get able to fit in, say, an uncut pizza. (If you just need something compact and don't need a large capacity, head to our guide to the best small air fryers.)

In our review, our tester noted no compromise in performance with this new design approach – the Double Stack delivers the same excellent performance as other Ninja air fryers we've tested. A wide range of different cooking modes make this model ultra-versatile, while the Sync and Match functions take all the pain out of cooking foods with different timing requirements – select your cooking mode, set your finish time and, if you're synchronizing the two baskets, select the cooking times for each, and it'll do the math for you. There's also virtually no heat leakage between the two trays, which is good news if you’re dealing with precise foods or don't want to waste energy when only using one basket.

The main down-side here is that the Double Stack is pricier than other dual-basket air fryers, so if you don't need to save on counter space you could get something as good for a lower price. But if you have a small kitchen, it could be well worth the extra investment.

Specifications

Type: Basket fryer
Wattage: 1500W
Capacity: 5qt / 4.7l

Weight: 12lbs / 5.44kg
Modes: 1

Reasons to buy

Produces crisp fries and chicken wings
+
5-quart / 4.7-liter capacity
+
Stylish design

Reasons to avoid

-
Struggles with frozen foods
-
Requires some experimentation to achieve evenly browned results
Buy it if:

✅ You like sleek appliances: The Corosri Pro LE is one of the best looking air fryers we've tested, with a sleek minimalist design.
You want to keep noise down: This air fryer is surprisingly quiet, producing no more noise than the gentle hum of a refrigerator.

Don't buy it if:

You cook lots of frozen food: The frozen food preset is only 10 minutes, which we found wasn't enough to cook frozen steak fries to perfection.
❌ You're cooking for a large family: It's not the smallest air fryer on test, but models like the Philips Airfryer XXL give you more room.

If you want a budget-friendly air fryer that's as stylish as it is effective, then the Cosori Pro LE Air Fryer L501 is worth considering. It's easy to use, with its LED touch control panel located on its glossy top, and it features seven presets for various foods including bacon, chicken and vegetables, and it enables you to adjust the temperature and cooking time to suit your tastes.

On test, we found the air fryer produced crisp, crunchy fries with soft, fluffy insides, and succulent juicy chicken wings. However, it struggled to evenly brown foods, so we found ourselves tweaking cooking times, and it wasn't effective when cooking frozen foods either.

The Cosori Pro LE Air Fryer L501 has some useful safety features: you have to fully insert the air fryer basket before the controls will work, and the basket as a button that you need to press before you can remove it from the air fryer. It also has a reminder to shake, which can be activated when setting the cooking time that will alert you halfway through cooking so you can turn the food to achieve an even crisp.

Doesn't crisp food as well as a standard air fryer
Buy it if:

✅ You don't have much room: If you enjoy cooking but don't have space for multiple appliances, this is a good option.
You use other Samsung Smart Home devices: You can manage them all through Samsung's SmartThings app.

Don't buy it if:

You don't really need a microwave: The Samsung Combi doesn't get quite as hot as a standalone air fryer, and takes a bit longer to get your fries crisp.
❌ You don't want to use an app at all: Some of the Samsung Combi's settings and options are only accessible through the mobile app.

If you don't have room for both an air fryer and a microwave on your kitchen counter, this multifunctional cooker from Samsung combines them into a single appliance - and it works as a convection oven and a grill as well.

During our tests we found that the Samsung Combi took a bit longer than a standard air dryer to crisp our fries, but it was extremely versatile. There's a huge array of presets, but the intuitive controls make them easy to find and select, and the mobile app allows you to control it from afar. We were particularly impressed by its capabilities as a convection oven, and could see it replacing a freestanding oven in a small kitchen if you're particularly short of space, or need to make room for a dishwasher.

It's certainly not small, and it's pricier than most of the single-purpose air fryers in this guide, but it has a smart design that won't look out of place in a modern kitchen, and it can replace so many other appliances that it does represent good value.

Weight: 13lbs / 5.9kg

+

+
Reduces cooking smells

Reasons to avoid

-
Crisper plate falls out if basket tipped up too high
-
Expensive
-
Requires some experimentation
Buy it if:

✅ You're worried about smells: The OdourErase technology does a good job preventing cooking smells escaping.
You're watching the calories: This air fryer uses less oil than any other on test.

Don't buy it if:

You're on a budget: The Instant Vortex is relatively expensive for an air fryer.
❌ You don't want to use tongs: The crisper plate tends to fall out when if you tip the basket.

The brand behind the iconic Instant Pot also makes air fryers, and its top-of-the-range model consistently turned out crisp fries and chicken wings, without emitting the cooking smells you'd usually expect from an air fryer. In our testing, the fries had crisp exteriors but soft, fluffy insides, and the chicken was moist, while its skin was crispy and retained loads of flavor.

The Instant Vortex Plus 6-in-1 Air Fryer with ClearCook & OdourErase improves on the previous iteration, the Instant Vortex Plus, with a plastic window in the basket and an interior light so you can keep an eye on food while it's cooking, while its built-in filters handle the odors. It's surprisingly quiet, too - one of the quietest we've tested to date.

However, it doesn't come with any cooking guides, which means you will need to spend time experimenting to achieve the right cooking duration and temperature, particularly when it comes to frozen food. We also found the crisper plate tends to fall out if the basket is tipped up too much when removing food, and the display doesn't take long to attract fingerprint marks. However, these are minor gripes, and it's otherwise an easy air fryer to recommend.

Dimensions (HxWxD): 12.1 x 10.7 x 10.7" / 30.6 x 27 x 27cm
Weight: 9.02lbs / 4.1kg
Modes: 11

Reasons to buy

+
Produces great food

Reasons to avoid

-
Controls on top
-
App requires 2.4GHz WIFI connection
Buy it if:

✅ You're on a budget: The K10 proves that you don't need to spend hundreds on an air fryer for great results.
You need a reminder to shake the food: The air fryer gives a gentle beep halfway through cooking to remind you to give the basket a shake so everything is cooked evenly.

Don't buy it if:

You want to cook different foods simultaneously: The K10 has a generous capacity, but only a single drawer.
❌ You want to place it on a high counter: The controls on the top will be hard to use if they're above eye level.

If you have yet to ever own an air fryer, but are a little nervous to try out new appliances and/or are conscious about spending money, the Ultenic K10 is a good beginner-friendly option to consider.

During our review, it was hard to find fault in its results. Its full-featured control panel comes with options like keep warm, automatic preheat, and a reminder to give the food a shake, giving you a lot of bang for your buck, especially with its budget-friendly price tag. It doesn’t have any other cooking function, however, apart from air frying, but its 11 presets and its app (which only works on 2.4GHz Wi-Fi) will make it a really easy-to-use and nice addition to the kitchen countertop.

In our tests we found it did a great job of producing crunchy, golden fries with fluffy insides, as well as crispy chicken wings with moist, tender meat inside. A particular feature we loved is that there's a little beep half way through select cooking modes to remind you to shake the foods, which is something that's really easy to forget about if you're an air fryer novice. You won't be able to cook two food types at the same time, though, and the controls are on the top so placing it on a high counter may not be the best position for it.

Weight: 31lbs / 14kg
Modes: 12

Reasons to buy

Smart Finish makes it easy to synchronize cooking times
+
Cooks evenly and timely

Reasons to avoid

-
Pricey and only available in the US at the time of writing
-
Cleaning is tough
-
Would have appreciated a second crumb tray
Buy it if:

✅ You're feeding a crowd: Two ovens that can be set to finish at the same time make it easier to prepare dinner for family and friends.
You want a versatile appliance: The Ninja Double Oven offers 12 cooking functions in total, and might just replace your regular oven.

Don't buy it if:

You're cooking for one: This is an excellent air fryer, but would be overkill for a single person.
❌ You don't live in the US: At the moment, the Ninja Double Oven isn't available outside the United States.

To the best of our knowledge the Ninja Double Oven is the only air fryer with a toaster oven design and two separate cooking compartments. Dual-zone air fryers usually achieve this with two drawers, but having two distinct cavities means this model is very flexible. The downside is that it's also harder to clean than models with removable drawers.

With the Ninja Double Oven air fryer, you can engage two different cooking functions at the same time: the top cavity can broil, toast, bagel, reheat and keep warm, while the bottom works like a standard air fryer. And there are 12 functions to choose from, including not just air frying but roasting, baking, toasting and more. In our tests we found it cooked very well across all its functions, and the Smart Finish feature makes it easy to co-ordinate two different kinds of cooking or two different temperatures so everything's ready at the same time.

The Ninja Double Oven is expensive, but if you want to have all your cooking bases covered, it’s an ideal solution for cooking for small or large groups alike. Unfortunately at the time of writing it's only available to customers in the US.

Weight: 30.62lbs / 12kg

+
Creates tasty, smoky flavors with minimal mess and hassle
+
Very intuitive to use
+
Only requires a small scoop of pellets

Reasons to avoid

-
Not big enough for larger gatherings
-
Accessories can’t go in dishwasher
Buy it if:

✅ Your only outdoor space is a balcony: If you love outdoor cooking but don't have a yard, this is the perfect solution.
You love smoky flavors: The use of wood chips infuses food with an authentic smoky aroma.

Don't buy it if:

You want to host parties: The Woodfire's capacity is enough for two to four people, but won't be enough to entertain a crowd.
❌ You want dishwasher-safe accessories: The accessories here must be washed by hand.

Though it’s still electric, the Ninja Woodfire Outdoor Grill is designed for outdoor use, making it a fantastic addition to your backyard or garden and just the perfect cooking appliance to see you through your summer barbecues and backyard parties. It’s primarily a grill and a smoker, but it comes with a few additional cooking functions that give you a bigger bang for your buck – it can also air fry, bake, and roast.

Even if you haven’t used an electric grill or smoker before, you won’t have a hard time using this one. On test, we found it incredibly easy to use, thanks in large part to its clever self-igniting woodfire smoke box that utilizes wood pellets to give your food that smoky flavors that traditional wood or charcoal grills deliver. And it does so without a flame and with very minimal mess. If you hate the clean-up after grilling, this might be a better option for you. Just bear in mind that the accessories here aren’t dishwasher safe so you still have some cleaning to do.

As far as its air frying function, it works well too. It comes with a 2.5-quart basket that gives you enough room to cook around 3lbs (1.5kg) of fries, every single piece of which came out crispy and fluffy during our testing.

Doesn’t have the usual presets
Buy it if:

✅ You want the best of the best: The Dreo ChefMaker delivers consistently excellent results, if your budget can handle it.
You're willing to spend serious cash: This performance doesn't come cheap, and the ChefMaker is one of the most expensive air fryers we've tested.

Don't buy it if:

You rarely cook meat: The ChefMaker's temperature probe and water atomizer system work particularly well for steaks, chicken and other meats, but if you're a veggie then they may be less useful.
❌ You need an extra large capacity: Check out the Ninja Double Oven instead if you want to cook particularly big portions.

The Dreo ChefMaker is so impressive with its cooking prowess and its ability to deliver moist-on-the-inside and crispy-on-the-outside results. That’s due to the fact that this air fryer is able to cook more precisely than many others.

Rather than the usual presets (bake, dehydrate, reheat etc), the ChefMaker offers Chef Mode, Classic Cook, and Probe Cook, so that you can either fine-tune the cooking experience, set it and forget it, or have the machine cook your food until its internal temperature is right where you want it, thanks to a nifty probe aka food thermometer that’s included in the box.

During testing, every meal we prepared turned out perfectly. We were particularly impressed by the way the ChefMaker cooked steak, with results that wouldn't look out of place in a restaurant.

The transparent glass basket is also a nice addition as you can keep visual tabs on your food without pulling the basket out. We also appreciate the fact that the components are dishwasher safe. And, though water atomization and super convection seem like buzzwords that Dreo applies here, make no mistake. This is a powerful, if pricey, air fryer.

Isn't recognized by Alexa in the UK
Buy it if:

✅ You appreciate simplicity: Although there are 12 settings to choose from, the control panel is responsive and easy to navigate.
You have an Alexa smart home setup: You can also use voice controls to operate this air fryer (but only if you live in the US).

Don't buy it if:

You want to cook multiple foods at once: The basket is quite roomy, but not quite big enough to cook two things at once with good air circulation.
❌ You want a cheap air fryer: The Pro III Dual Blaze is one of Cosori's more expensive models, though it's often available for a discount from retailers like Amazon.

If you need an air fryer that's smarter than average, the Cosori Pro III Dual Blaze, also known as the Cosori Dual Blaze in the UK, could be an attractive option. It's a smart air fryer, but there are some caveats: its Alexa support is US-only, and it needs to be connected to a 2.4GHz wi-fi network to communicate with devices such as smart speakers.

The app is very good, featuring over 100 tasty-looking recipes, with ingredients, method and settings required on the air fryer all outlined. It is possible to select a recipe and the temperature and time remotely on the app, however you'll need actually press the start/pause button on the air fryer itself to activate it.

Beyond its app, the Cosori Pro III Dual Blaze features an innovative design that includes an upper and lower heating element to cook foods quickly and evenly. It comes with 12 presets including chicken, veggies, fries, frozen, bake, reheat and roast. Each of these can be adjusted by temperature and/or duration, however we found in testing that they were pretty accurate by default, delivering golden waffles, crispy hash browns with fluffy insides, and equally crispy fries with no need to pre-heat the air fryer or shake the basket mid-cook.

This is one of the most expensive air fryers in the Cosori line-up, but it's one of the biggest and fastest too. It's worth considering even if you're not too bothered about the app recipes or control as it's a very capable cooking appliance.

How to choose the best air fryer for you

What will you be cooking?

Different air fryers work best for different foods. Basket air fryers tend to be healthier because they funnel the juices, as well as the fat, away from the food but you can’t check on the food without opening them and letting cold air in, which can stall the cooking process. Bowl air fryers often have glass lids so you can keep an eye on your meal, but the cooking juices remain in the air fryer and in contact with the food, making it tastier but not as healthy.

How much will you be cooking?

If you’re feeding four or more mouths, look for larger air fryers, which can hold around 6.5 quarts / 6 liters, while couples will find designs that have a capacity of around 2.5 quarts / 2.5 liters will be sufficient. Some of the best air fryers also have more than one compartment, which means you can cook multiple foods at the same time. For more tips and tricks on getting the most out of your appliance, take a look at our guide to how air fryers work.

How much space do you have?

If you’re tight on space look for air fryers that offer a multitude of different cooking methods, to cut down on the number of appliances that clutter up your kitchen countertop. Sometimes an air fryer isn't the right appliance. For example, you could consider an Instant Pot or alternative multi-cookers, which includes some models that mimic the effect of a standalone air fryer.

Do you want to control it remotely?

Consider whether you want an air fryer with smart features that means you can switch it on or off from your smartphone.

What is your budget?

The price of air fryers varies enormously, with budget models starting below $100, and large-capacity premium fryers costing well over $300.

What types of air fryers are there?

Basket air fryers

Basket air fryers are the most popular type of air fryer. They have a slide-out basket or tray which slots in to the main unit, and tend to be available as a single or dual-drawer. Food like fries may be browned unevenly if it isn't rearranged or tossed around during cooking.

Oven-style air fryers

These are much larger than basket air fryers, and are often about the same size as a microwave. They have a door rather than a drawer, and use shelves rather than baskets. The air frying function is able to circulate air around the food more efficiently to achieve a more even crisp. Some may also include a rotisserie, and other accessories.

Halogen ovens

Although sometimes described as air fryers, halogen ovens work in a different way. Instead of circulating hot air a halogen oven uses infrared to constantly heat the food. This means that they can be more versatile than the more traditional air fryer, with a larger capacity and more forgiving shape of cooking area.

Frequently asked questions about air fryers

Is air-fried food healthier?

Air fryers use substantially less oil than deep frying: some foods, most of which are frozen or have naturally occurring fat, like chicken wings, are suitable for air frying without any oil at all. Fries, roast potatoes, and other traditional crisp foods will need some oil, but how much varies between air fryers.

In our tests, manufacturers' instructions have recommended anywhere from 1tsp to 1tbsp of oil per 1.1lb / 500g of fries, so if you want to use as little oil as possible - we'd suggest you check how oil is required before you purchase a specific model. It's also crucial to remember the healthiness of what you make in your air fryer all depends on what you actually put in it, to begin with. To find out more, read how healthy are air fryers?

What can you cook in an air fryer?

Fries, roast potatoes, chicken wings and other deep-fried favorites are obvious dishes to cook in an air fryer, but that's not all you can whip up in one of these handy kitchen gadgets. You can prepare anything you can cook in a traditional fan oven, space permitting, because they work in the same way.

So whether that's frozen foods, mini pizzas, or even gnocchi and ravioli - it can all be cooked in an air fryer. You can even make fudgy brownies in an air fryer, in less time than it takes in an oven.

We've tried to cook pretty much everything apart from soup in an air fryer. We found that an air fryer can rival KFC when it comes to fried chicken, and was also the answer when it came to creating crisp, crunchy crackling on pork belly.

It also proved to be the best way to cook cinnamon rolls and Krispy-Kreme-style donuts.

As well as being used in place of an oven, air fryers can be an easier way to prepare dishes usually cooked on a stove, without having to watch them like a hawk and turn them before they burn. In particular, we discovered French Toast and grilled cheese work extremely well in the kitchen gadget.

If you're a fan of fries but unsure how to go about making them in an air fryer, then check out our advice, which even details an air fryer trick that's a game-changer when it comes to cooking fries.

We're also big fans of reheating takeout in air fryers: they're particularly good for pizza and fried chicken.

If you're still unsure we've got plenty of inspiration when it comes to what you can cook in an air fryer?.

What can't be cooked in an air fryer?

Air fryers are very versatile but there are some things you should avoid. For example, we found 5 foods to avoid putting in an air fryer. These include foods dipped in batter, as the liquid will simply slide off the item and leave a mess in the frying basket. Anything lightweight, such as an individual slice of bread or leafy greens, is likely to get blown around the cooking cavity. That means it may cook unevenly or even burn.

With many air fryers large joints of meat can be tricky too: if they're too big for the drawer the hot air can't circulate properly. That means the joint won't be evenly crisped and browned. And we wouldn't recommend trying to cook red meat medium rare or medium: the outside cooks too quickly and can leave the center raw.

How does an air fryer work?

Despite its name, an air fryer doesn't actually fry. Utilizing a very cleverly designed fan oven, it efficiently uses airflow to cook in a way and at a speed that conventional ovens, even fan ones, cannot.

Some of the best air fryers are also multi-cookers, meaning that the air circulated doesn't just air fry. A single countertop device can make tasty fries but also work as a toaster oven, a dehydrator, a slow cooker and a pizza oven, as well as heat up last night's takeout leftovers and bake brilliant bagels too.

How we tested these air fryers

To compare each air fryer, we cooked up batches and batches of fries and chicken wings, and evaluated the results for crispness and evenness of browning. In the case of chicken wings, we also checked how moist and juicy the meat was.

Plenty of cooking modes are a bonus, as are features like odor-reduction to limit the spread of cooking smells, but we also appreciate an air fryer that didn't require us to read a thick instruction book before we could get started. We rated each machine on ease of use, how loud its fans become (some are much noisier than others), and how hot the exterior casing got during use.

The type of controls is an important consideration (physical buttons or a touchscreen), as is the inclusion of a window and/or light that lets you check on the food while it's cooking without opening the air fryer and allowing heat to escape.

Afterwards, we rated each machine on its ease of cleaning, and durability of its body and parts. Some air fryers have components that are dishwasher-safe, while others must be cleaned entirely by hand.

Extra features like accessories and recipe books for ideas are a welcome addition, as are cooking charts that help you understand how long it'll take to cook your food compared to using a conventional oven.
