Sear/Sauté - Use heat from underneath to cook like you would on the hob - think chilli, risotto, curry and more. Perfect for browning meats, sautéing vegetables and simmering sauces - whether you're searing braising steak to perfection before slow cooking, or caramelising onions to give a sauce maximum flavour. That combination means you can cook two different types of food at once, giving a complete meal with very little hassle. My only minor complaint is that the crisper plate is a bit fiddly to remove to get to the bottom layer: I found using a pair of insulated rubber oven gloves was the best way.

Make dinner in 15 minutes with the new Ninja Speedi - thanks

Comparatively expensive, this model won’t be for everyone, but its unique design lends itself to foods that other air fryers can’t even think about. Combining and air fryer and grill in one appliance makes a lot of sense: it doubles up of the number of uses and, for the grill in particular, keeps smoke and smells inside the appliance. Mostly, products like this are very expensive, but the Salter Aerogrill is cheaper than a lot of air-fryer only cookers. Inside, there’s space for a 6-litre air fry basket, which is enough space to cook for large families. For grilling, there’s a grill plate that drops into place, which is big enough to take large skewers of food, plus whole steaks and portions of fish.Slow Cook - Slowly cook food at a lower temperature for tender results - perfect for pulled pork, veggie chilli and more. As with the previous model, you can use just a single drawer, or use each drawer independently, synchronised (individual settings, but the air fryer will get both of your selected programmes to end at the same time or matched with the same settings. The standard position is to have this crisper plate at the bottom, which works for regular air frying. In this way, the Speedi is similar to most air fryers. I did find that it was easier to use silicone tongues to turn food, as the pot is a little hard (and hot) to remove and shake. Cooking for 20 minutes at 200ºC, with 125ml of water in the bowl, chips were evenly cooked and had a nice crispy texture to the outside, while the inside remained soft and moist. Quite possibly, this is the best that we’ve seen any air fryer perform. Frozen hash browns and grilling rump steak were also cooked to perfection. Pressure cooking works well, too, reducing the amount of time it takes to cook a lot of food.

Steam Bake - Create fluffy cakes and bakery-style bread at home, from garlic bread knots to cookie cheesecake, or savoury dishes like baked vegetable gratin. The oven can also employ its Element iQ tech to direct power where it’s needed to eliminate cold spots in food. In practice, it worked perfectly, leaving us with evenly cooked home chips that had a crispy outside and fluffy inside. Although it is an air fryer, the Ninja Speedi is more than that: built to deliver multi-level cooking, this device can dish out complete meals in just 15 minutes, as well as grilling, steaming and, of course, air frying. You can cook individually, use the same setting on both drawers or, cleverly, use different settings on each drawer but have them synchronise to finish at the same time. There are options to air fry, max crisp (a 240C turbo setting), roast, reheat, dehydrate or bake. All the included accessories are dishwasher safe for easy cleaning, and you can also use the Steam setting to steam-clean the inside of the lid and unit.

General air fryer foods (chips, hash browns, burgers and the like) were cooked exceptionally well, although we did have to add a bit of cooking time beyond the recommend to some food types. Using the grill, we found that its heat was slightly uneven, but moving food around manually when turning it was enough to overcome this problem. We have to say that the manual controls are a little confusing with lots of buttons for dedicated cooking modes, such as seafood, chips, fish and meat. A simpler layout would help, although once you’re used to the T22, it’s often easier to set a temperature and time manually.

This is a proper air fryer, too, although topping out at 210°C it can’t quite get the crispiest of results that air fryers with a higher temperature can reach. I do really like the steam air fry option: this creates perfect chips that are crispy on the outside and fluffy on the inside. As with the other Proscenic products that we’ve reviewed, the Proscenic T22 is a smart product. It can connect to your Wi-Fi giving you control via the app or even Alexa. The app gives remote control, plus a load of recipes: you still have to do the prep and cooking, but you get step-by-step instructions and the air fryer will be set to the correct settings.Secondly, the top layer can cook faster than you may expect. I found that my kebabs were cooked a few minutes before the bottom layer was, so needed removing earlier. Even so, for a mid-week meal, it took 20 minutes (including prep) and a single pot to produce something that would otherwise have required multiple pots and grills. Every air fryer on this list has been rigorously tested in real-world settings. Our reviewers measure the performance of an air fryer by examining how well the appliance cooks a range of foods, from chips and frozen hash browns to meat and more. Next, I moved on to multi-level cooking. I made some halloumi kebabs, coated with a soya sauce-based dressing and placed these on the top level. On the bottom level, I put 200g of rice with 500ml of water, and set a cooking time of 15-minutes at 180°C.
