Food cooks best in air fryers if you give it a shake mid-cooking, resulting in an even finish. With many models, you’ll need to dig out a pair of oven gloves to do this. The AF400UK makes this simple by including handles on the outside of its drawers. Pull one out and the air fryer stops (both drawers stop in Sync or Match modes), so you can shake away and reinsert.

ENERGY-SAVING: Save up to 65% on your energy bill* (*testing and calculations based on recommended cook time for sausages, using air fry function versus conventional ovens) When it comes to cooking, timing is everything. Perfect for families and large households, the Ninja Foodi MAX Dual Zone 9.5L Air Fryer does the thinking and timing for you. Cook 2 different foods with different temperatures, times and settings in 2 separate cooking drawers – and have both ready to serve at exactly the same time using the SYNC feature! More people to feed? MATCH settings across both zones to make double the amount of food in the same amount of time! Cooking for extra guests or feeding the whole family? Use the MATCH feature to double your serving size, with the same cooking program and time across both drawers.With the SYNC feature you can cook two different foods using different times, temperatures and programs – both are ready to serve at the same time! The large capacity of the Ninja Foodi Max Dual Zone Air Fryer AF400UK makes it a bulky appliance. Measuring 32.5 x 41.5 x 27cm / 13.9 x 12.8 x 17.1inches (h x w x d) and weighing 8.8kg / 19.8lb, this isn’t an appliance you’ll be storing in a cupboard and lifting out every time you need it. Cooking for two different dietary requirements? Cater for everyone by cooking vegetarian food in one drawer and meat in the other. Reheat – Restore leftovers to that delicious fresh-out-of-the-oven finish, perfect for reviving leftover pizza, quiche, spring rolls and more. Effectively, this model delivers all the great features of last year’s model, only with a 9.5-litre total capacity. For larger families, or simply for cooking bigger items, this is a great fryer – provided you have the room to store it. Design and Features

testing and calculations based on recommended cook time for sausages, using air fry function versus conventional ovens At the end of the cooking time, the hash browns were super-crispy on the outside, yet evenly cooked and still fluffy on the inside. This is a vast improvement over cooking them in the oven. At the end of cooking time, my chips were perfectly cooked – evenly crisp throughout, without any sign of being burnt or overcooked. Everything here can be cleaned in the dishwasher once you’re done, meaning there’s very little clearing up to deal with. PerformanceWe were impressed by the Sync feature, which allows you to cook two different foods with different cooking modes, temperature,s and durations, to be ready at the same time. Alternatively, you can set one zone with a cooking mode, temperature, and duration, and press the Match button to duplicate the settings in both zones, doing away with fiddling with the controls again.

I started by cooking some chips in the air fryer, using the 200ºC setting. Although I had to shake the contents of the drawer two or three times during cooking, it’s all the interaction the AF400UK required. If you want to use the two drawers together, you have a choice of two modes: Match and Sync. Match applies the same settings to both drawers, letting you double-up portions. Sync allows individual settings, but the AF400UK ensures that both drawers complete cooking at the same time. Take mealtimes to the MAX with the large capacity air fryer that cooks 2 foods, 2 ways, and finishes at the same time.To give the Max Crisp function a go, I used it to cook frozen hash browns – which all too often come out of a regular oven slightly soggy. Although they’re supposed to be cooked in the oven for around 20 minutes, I set the cooking time to 11 minutes because of the high 240ºC temperature.

The easy-to-use digital control panel with a countdown timer makes it easy to see how much cooking time is left. Cook the same food in both zones to make twice the amount of food in the same amount of time! Or easily cook two different foods with the same cooking instructions. There’s no getting around the fact that the Ninja Foodi MAX Dual Zone Air Fryer AF400UK is a beast of a model. Measuring 325 x 415 x 270mm and weighing 8.8kg, you’re going to need a fair amount of space to store it.

The problem with most air fryers is that once you come to love what they do and become used to them, you then have to work out how to cook different items at the same time. Last year’s Ninja Dual Zone Air Fryer AF300UK solved that issue by including two individually controlled drawers. This year, we have the larger model the Ninja Foodi MAX Dual Zone Air Fryer AF400UK, presenting even more cooking room. As with the older model, the AF400UK excels for cooking options. Each drawer can be controlled individually, with a choice of Max Crisp (240ºC heat for crisping up chips, for example), Air Fry, Roast, Bake, Dehydrate (perfect for saving herbs) and Reheat. You can control the temperature for each mode and select a cooking time.
