The best Ninja air fryers combine the functionality of multiple kitchen appliances into one stylish, countertop-friendly product. Cutting the amount of oil needed in conventional cooking by as much as 75%, they offer a healthier cooking option. They're also speedy, promising to cut cooking times by as much as 50%.
Ninja is the sister brand of Shark, and its range of air fryers has won an army of fans in recent months. Typical cooking functions can include air fry, roast, bake, dehydrate and reheat, with rapidly circulated hot air resulting in food that is perfectly cooked every time.
Of course, with that degree of functionality, the prices aren't perhaps as low as some of the other brands on the market at the moment—but you might be pleasantly surprised. Ninja offers fantastic value for money, with long-lasting products (typically backed by a decent warranty) that will prove themselves to be invaluable.
The brand has a range of air fryers and health grills, with the latter combining air fryer functionality with a BBQ-esque twist. The range of food the best air fryers can cook is amazing: from frozen to fresh, they can serve up meat, fish, vegetables, chips, pastries, fresh bread and more. But which is the best Ninja air fryer in 2022? We've rounded up the best picks in our buying guide.
How we tested the best Ninja air fryers
As with all the kitchenware products we test—from the best kitchen gadgets to the best induction pans—we tried out the Ninja air fryers in a real-life kitchen to see how they performed in an everyday home. During testing, factors we assessed included:
- How well they performed—we looked at how easy the air fryer was to use, and, most pressingly, how it performed when cooking various food types.
- Its design—we considered how each machine looked, as well as how functional it was. Was it bulky? Easy to move? Easy to assemble?
- Ease of care —we looked at how easy it was (or wasn't) to clean the air fryer. How simple was it to remove the parts that needed cleaning, and how easy was it to maintain? Are parts non-stick, and can any of the components be put in the dishwasher?
- Overall value for money—with all of the above taken into consideration, did we feel each Ninja air fryer was worth its price tag?

The best Ninja air fryers, as tested by our expert
1. Ninja Foodi Dual Zone Air Fryer - AF300UK
Reasons to buy
Reasons to avoid
Due to its range of cooking modes, ease-of-use and general versatility, the Ninja Foodi Dual Zone Air Fryer is a worthy winner that ticks all our boxes. It promises dual functionality, meaning its two drawers can be used to cook two different food types, in two different ways, at the same time. Even more impressively, the air fryer promises to have both ready at the same time, meaning neither gets cold.
We tested this AF300 by using 'bake' mode to heat up a pie on one side and 'air fry' mode for chips on the other. The results were perfect: the pie was golden and piping hot, while the chips were crispy on the outside and soft within. And best of all, it was just so quick: from start to finish, everything took less than 20 minutes. The enclosed recipe brochure was handy for getting timings right, and also offers plenty of food for thought if you're all-out of dinner ideas. We've got our eyes firmly on the halloumi fries recipe, if you were wondering.
In short, it offers fantastic value for money and matches all the requirements that the typical modern family might have. The AF300 arguably brings together all the best bits of the various Ninja air fryers. It offers six cooking modes, has a relatively neat design (although it is pretty bulky, so might not be a great choice if you don't have much space) and has a generous capacity, too, making it a great choice for families or individuals who prefer to batch-cook their meals.
There were some small downsides: it is quite loud, although we imagine the noise will quickly disappear into the background once you get used to it. It also set our fire alarm off twice the first time we used it, presumably due to the heat it was expelling.
2. Ninja Foodi MAX Health Grill & Air Fryer AG551UK
Reasons to buy
Reasons to avoid
Combining an air fryer with a grill, the Foodi MAX Health Grill & Air Fryer AG551 is a strong choice for BBQ fans. Promising perfectly chargrilled food every time, it also offers the multi-functionality that we've come to expect with Ninja's Foodi products, with modes including 'roast', 'bake' and, of course, 'air fry.'
We tried it with salmon fillets, garlic bread and lasagne (not all at once, we should add), and the results were great. We tried using 'reheat' for the homemade lasagne (and even when it didn't look quite crispy and golden enough, a few more minutes revived it), while the garlic flatbread sizzled into life. We were slightly wary of the salmon fillets: the handy guide suggested that these would take less than 10 minutes, with no need to flip. But it worked: 'grill' mode produced fish that was tender and flaky, in about eight minutes flat.
However, we were most impressed with its meat cooking: it's a BBQ with its very own brain. There's no need to flip or turn food as it cooks, as the AG551 cooks both sides at the same time when in 'grill' mode. We tried it with kebabs and steaks, and they were perfect—mouthwatering, tender, and juicy.
While it's brilliant for 'flatter' foods, such as chicken breasts and steaks, however, it's worth noting that this machine can't quite be used in the same way as other Ninja air fryers. We thought about trying to roast a large chicken in it, for example, but quickly realized that it wouldn't fit under the lid.
What it lacks in height, however, it more than makes up for in width and depth, as it can hold up to six portions worth of meat, fish, and poultry. On that note, it's also incredibly heavy. It took two of us to carry it into position, so if you're looking for a lighter-weight air fryer that can be moved around the kitchen, you might want to consider another Ninja model.
3. Ninja Air Fryer AF100UK
Reasons to buy
Reasons to avoid
A great introduction to air fryers, Ninja's AF100 model is ideal for beginners and anyone on a budget. Coming in at the lowest price point, it offers four classic cooking modes and is also a neat all-rounder for someone who has less space in their kitchen. However, it's worth noting that due to its small capacity (3.8l), it's not the best choice if you plan to cook for more than three or four people at a time.
We loved the smooth curves of the AF100's upright design, with its taller-than-wide dimensions making it a great choice for anyone who doesn't have much countertop room. The instruction manual was easy-to-follow and the set-up couldn't have been simpler. We tested it with fries from the freezer and were pleasantly surprised by how quick and simple the whole process was. Cooked using 'air fry' mode, the AF100 blasted the fries at 180°C for about 15 minutes, which resulted in perfectly crispy potatoes. It's worth being aware that the greater the number of fries you'll be cooking, the longer the cook time.
We later tested it with a chicken breast and roasted vegetables; while the chicken was cooked to perfection, we underestimated the power of the air fryer and the vegetables ended up being charred rather than roasted, but this was largely down to our misplaced scepticism that it could roast the veg as quickly as it suggested.
It's worth remembering that the cooking time of a Ninja air fryer is around half that of a conventional oven, so do be sure to check the guidelines to ensure you don't accidentally burn food.
4. Ninja Foodi MAX Dual Zone Air Fryer AF400UK
Reasons to buy
Reasons to avoid
Ninja's Foodi MAX Dual Zone Air Fryer AF400UK is not for the faint-hearted. Huge in size, its two baskets each boast a 4.75l capacity (adding up to 9.5l) in total, making it a fantastic choice for households that need to cook for larger groups on the regular —in fact, Ninja advises it can serve eight-plus people at a time. It's also worth noting that it's heavy, clocking in at just under 9kg, so make sure you know where its forever home is going to be before you buy it, as you don't want to be repositioning it too often.
This machine also gives you the choice to decide whether you want both baskets to operate with the same cooking function at the same time, meaning you can opt to 'sync' or 'match' them. 'Match' is ideal if you need to cook a huge amount of something (for example, if you're cooking a pasta bake for a large group of people), while 'sync' gives you the freedom to cook two different food types in two different ways at the same time.
We tested this with a breakfast-time meal of fresh sausages and bacon (which we cooked on the 'air fry' setting), paired with frozen hash browns (which we cooked on 'max crisp'). It couldn't have been easier—or more delicious—and also resulted in a lot less washing-up than it would have if we'd cooked in a conventional oven. Altogether, they took about 10 minutes to cook but probably would have been ready a minute or two quicker if you were less fussy about having crunchier hash browns.
5. Ninja Air Fryer MAX AF160UK
Reasons to buy
Reasons to avoid
The Ninja Air Fryer MAX AF160 is made for smaller homes. With its upright design, it requires less countertop space than some of the other models on this list but can still comfortably feed a family. We tested it on homemade fish and chips and it was delicious: the breaded fish was crispy and flaky, while the chips were perfectly golden. We did this with the 'max crisp' mode, which is specifically geared towards freezer food and circulates air of 240°C around the fryer.
We also experimented with the other modes: the 'reheat' function brought a slice of pepperoni pizza sizzling back to life, though the results were more or less on a par with what you'd get if you had popped it on the microwave. We also tried the MAX AF160 out on some frozen breakfast pastries (pain au chocolat, if you're wondering, air fried for about eight minutes), and they were cooked with an even finish and a melt-in-the-middle center. They did need a moment or two to 'sit' and cool down before eating, though.
On top of its cooking performance, the MAX AF160 is also easy to clean. We found the basket responded best to a soft sponge and warm, soapy water, but it can also be popped in the dishwasher, too.
The MAX AF160 was a very close contender for our all-round winner, losing out simply due to its smaller capacity. All in all, it's a fantastic option for beginners, and at a decent price point to boot.
How to choose the best Ninja air fryer for you
There are several factors to consider when deciding which Ninja air fryer is the perfect fit for your lifestyle. These include:
- Size: How much room does the air fryer require, and where will you store it in your kitchen? Some of the bigger-capacity air fryers can take up more room due to their dual-drawer design, meaning that they might not be a great choice for kitchens that are lacking in countertop space.
- Volume: How much food do you anticipate cooking in your air fryer on a daily basis? If you're hoping to use it for almost every aspect of your evening meal, for example, you might prefer a design with drawers. If you'll use it occasionally rather than regularly, you might prefer to choose a smaller product.
- Functions: Are there specific cooking functions you're looking for, or are you more influenced by other factors? Each Ninja air fryer offers different cooking modes, meaning you need to check the model you've got your eye on meets your needs.
Of course, like any appliance, air fryers require careful maintenance. However, if you've ever wondered how to clean an air fryer, Ninja couldn't make it easier. Dishwasher-friendly by design, the drawers and plates of Ninja air fryers are typically non-stick thanks to a PTFE coating, meaning even accidentally burnt-on food is easy to deal with.
Which Ninja air fryer is the biggest?
With a total capacity of 9.5L, the Ninja Foodi MAX Dual Zone Air Fryer AF400UK is the biggest. It boasts two 4.75L drawers, meaning that you can cook your whole meal in one go, with minimal fuss. Each drawer can be programmed to cook with a different function, meaning you could roast and dehydrate at the same time, for example.
If you're looking for the Ninja air fryer with the biggest single compartment capacity, the Ninja Air Fryer MAX AF160UK is a great choice. With its 5.2L drawer, it can comfortably rustle up everything from a roast chicken dinner to a burger and fries.
