In the US, this Ninja model is called the called the Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer (DZ550). In the UK, it’s the Foodi MAX Dual Zone Air Fryer (AF451UK).

It’s at the top of the list because it has every feature you could possibly want, including a cooking probe for perfect meat and fish.

Each basket has a 5QT/ 4.75L capacity and you can programme them independently, match them, or even set them in sync mode – to finish cooking at the same time, for hassle-free meals.

It has six cooking modes: air fry, max crisp air fry, bake, roast, dehydrate, and reheat. There’s no grill function, however.

Like all Ninja models, it’s intuitive and incredibly easy to use and produces well-cooked, crispy food. It demands plenty of space though, with dimensions of 32.5 (H) x 41.5 (W) x 27cm (D)/12.8 (H) x 13.9 (W) 17.1in (D).

One more note: if you already have a Ninja Speedi or Health Grill, you may find yourself slightly disappointed by the fact that’s it’s an almost entirely plastic build.

One thing that sets this model apart from other entries in this round-up is that its 9L capacity is unevenly split across two drawers. There’s a main 6L drawer and a smaller, 3L drawer for sides. However, at 42 x 31 x 38cm, it’ll take up more space than the Ninja Foodi and you’ll get a slightly lower cooking capacity,.

Still, it is an attractive appliance, with digital touchscreen controls on top and a grey and metallic build that makes it appear much less of a countertop monolith than some rivals.

It has eight presets. Many are specific rather than general, such as frozen potato, fresh fries, whole fish, and meat chops, although there is a handy reheat setting. The cooking temperature is also low enough to dehydrate fruit and meat and proof dough.

You can sync the drawers so they finish cooking at the same time, copy so both drawers have the same setting, and add a shake reminder. (A shake alert isn’t something you get on all Ninja models.) It also comes with a companion app, so you’ll get an alert to your phone when food is ready.

But the downside is that the on-appliance controls aren’t as intuitive as those of some rivals, and the icon controls can be hard to read in bright light, so there’s a bit of a learning curve to using it.

In our test, we were impressed with the quality of the food produced and would recommend it, although it may not be the best choice for novice air fryer cooks.

If you want a dual-drawer air fryer but can’t justify its countertop footprint, the Double Stack (DoubleStack in the US) is worth a look. It provides a lot of cooking capacity for the amount of space it takes up. Not only does it have two cooking drawers with an overall 9.5L/10QT capacity, but the cooking racks allow you to stack food in two layers in each drawer. If a common meal for you is chicken or fish accompanied by two or three types of vegetables, you’ll be able to do it all in the Double Stack without resorting to other cooking methods.

Like Ninja’s other dual-drawer air fryers, it has an easy-to-use control panel, with match and sync functions. It has has fewer modes than many other models – air fry, max crisp (for frozen food), bake, roast, reheat and dehydrate – but you can adjust them by time and temperature to cook almost anything you want.

But as its heat sources are at the backs of the drawers we found that it cooks some types of foods slightly unevenly. As there’s no shake alert, you’ll need to remember to step in midway and mix up potatoes or fries. Altogether though, it’s fast, efficient and makes crispy, crunchy food.

At 38cm wide, 31.5cm deep and 30.5cm high, the Chefree dual-drawer is around the same size as the Ninja Foodi, although it has a slightly lower, 8L capacity. However, it also has a lower price and offers the same functionality as the better-known model.

It has easy-to-use touchscreen controls, with eight one-touch programme settings: air fry, roast, air crisp, broil, bake, dehydrate, reheat and grill. You can adjust the time and temperature for each of these as well. It also has sync and match functions and a shake alert.

It delivers excellent results – although you might find that you need to adjust time and temperature down if you’re used to a less powerful appliance. It’s good for newbies as well: it comes with a comprehensive cooking chart that’ll give you cooking timings and temperatures for everything from butternut squash, to bacon, to salmon fillets, to prawn tempura.

If your budget won’t stretch to a Ninja, this Sharp dual-drawer air fryer is an excellent alternative. It has many of the same features, including the ability to match and sync cooking across both drawers. It’s more compact than most dual-zone models as well, but it does have a slightly lower, 8L cooking capacity.

The controls can be slightly confusing until you get comfortable with them, which isn’t helped by the fact that the accompanying manual is thin, so be prepared for a bit of experimentation at first. You can choose to cook by food type (including fries, beef, vegetable, whole chicken, bacon, fish, potato, pizza, chicken nuggets, prawns, snacks, and toasted sandwich) or by cooking mode (air fry, bake, roast, cook from frozen, dehydrate, keep warm, pre-heat, or reheat).

Once you’ve figured out how you prefer to use it, you’ll find that cooking is fast and produces great results. It’s easy to clean as well.
