Ninja Air Fryer AF400UK: air fryer for home

Hi! I’m Jenny, a healthy lifestyle enthusiast with ten years of experience, and today I’ll be sharing my experience with the Ninja Foodi MAX AF400UK air fryer. I hope my insights will help you make the right choice. Cooking healthy food can be easy if you have the right tools.

Why I chose an air fryer

The principle of an air fryer is that it uses hot air to fry ingredients, much like a traditional deep fryer. However, in this case, you only need a few grams of oil, so the dishes come out with minimal calories. Additionally, it eliminates the possibility of forming aldehydes. The result is a delicious crispy crust, a slim figure, and no harm to your health.

What you can cook

Having an air fryer like this in the kitchen allows you to bring all your culinary fantasies to life while maintaining a healthy lifestyle.

This model offers the following cooking functions:

• Air Fry — air frying
• Roast — traditional roasting
• Bake — baking
• Dehydrate — dehydrating
• Reheat — reheating
• Max Crisp — maximum crispiness

Thanks to these features, I can easily load salmon in one basket and steak in the other. Both dishes turn out flavorful, well-cooked, with a light golden crust on top, and without any unwanted smells. With just one process, I’m able to meet the preferences and wishes of all my family members.

There are many discussions online about the price of this model. In my opinion, the Ninja Foodi Max Dual Zone Air Fryer AF400UK offers the best value, justified by the convenience it provides.

There are two versions of this model — a 9.5-liter and a smaller 7.6-liter one. If you have a family of 5-8 people, like mine, the larger option would be the best choice. That way, you’ll even have a few extra portions to take as lunch to work.

The main feature of this air fryer is its two compartments, allowing you to cook two dishes at the same time. It turned out to be incredibly convenient. Each compartment can be set to different modes, temperatures, and cooking times.

If you need both dishes ready at the same time, there’s a sync option (Sync function). This means that even with different settings, the food in both zones will finish cooking simultaneously. The system briefly pauses frying in one zone while waiting for the other to catch up. Plus, the aromas don’t mix between the baskets.

I often cook chicken wings and vegetables, and both dishes are ready at the same time.

Regarding the design

I liked the Ninja Foodi Max Dual Zone AF400uk Air Fryer in black. The chrome accents look stylish and solid. The aluminum base, plastic body, and glass panel give it quite a bit of weight. Be prepared, as this is a stationary appliance weighing 8 kg. It has a considerable size (48 cm in length and 33 cm in height), so you should make sure to have enough space on your kitchen counter in advance.

The buttons, rotary knob, display, and easy section removal – everything is designed for simplicity and convenience while cooking.

As for the noise, it’s comparable to a quiet vacuum cleaner (up to 50 dB). If you use it behind closed doors, you won’t disturb other family members. For instance, you can get up early, load all the ingredients, set the timer, and go back to bed for a bit more rest.

My Experience

From the very first days of using this air fryer, I was impressed by how quickly and evenly it cooks food. Once, I made broccoli in just 10 minutes – they were crispy, retained their color, and kept all their nutrients. I also tried roasting a whole 2 kg chicken, and it came out perfectly in 45 minutes, which is almost twice as fast as in a regular oven.

One time, I was preparing dinner for guests: chicken wings, baked potatoes, and a vegetable side dish. Thanks to the Sync function, everything was ready at the same time, and I didn’t have to worry about one dish getting cold while the other was still cooking.

Testing the Ninja Foodi MAX AF400UK Air Fryer

Test 1: Chicken Wings with Vegetables

Preparation

• Ingredients: 1 kg of chicken wings, 500 g of broccoli, 1 tablespoon of olive oil, spices (salt, pepper, paprika).
• Process: First, I prepared the chicken wings by marinating them in a mix of spices and olive oil for 30 minutes. I simply drizzled the broccoli with olive oil and added a bit of salt.

Cooking

• Mode: Air Fry
• Temperature: 200°C
• Time: 25 minutes for the chicken wings, and 10 minutes for the broccoli.
• Sync Function: I placed the chicken wings in one zone of the air fryer and set the timer for 25 minutes. After 15 minutes, I added the broccoli to the other zone, using the Sync function to ensure both dishes would be ready at the same time.

Result

The chicken wings came out crispy on the outside and remained juicy on the inside—just the way we liked them. The broccoli turned out great as well: it retained its bright green color and became pleasantly crispy. The cooking time is at least 30 minutes faster compared to a conventional oven. The Sync function allowed me to serve both dishes hot and at the same time.

Test 2: Baked Salmon with Potatoes

Preparation

• Ingredients: 2 salmon fillets (about 200 g each), 500 g of potatoes, 2 tablespoons of olive oil, spices (salt, pepper, lemon juice, rosemary).
• Process: I cut the potatoes into pieces, drizzled them with olive oil, and sprinkled them with rosemary. I lightly coated the salmon with olive oil and seasoned it with salt, pepper, and lemon juice.

Cooking

• Mode: Roast for the salmon, Air Fry for the potatoes
• Temperature: 180°C for the salmon, 200°C for the potatoes
• Time: 20 minutes for the salmon, and 25 minutes for the potatoes.
• Sync Function: I placed the salmon in one zone of the air fryer and the potatoes in the other, using the Sync function to ensure both dishes were ready at the same time.

Result

The salmon turned out tender and juicy, with a light lemon aroma. The potatoes had a crispy crust and soft interior, just like my mom makes. Once again, the Sync function ensured both dishes were ready simultaneously.

Both tests confirmed the high efficiency and convenience of the Ninja Foodi MAX AF400UK Air Fryer in preparing different dishes at the same time.

Bonus — A Few Healthy Recipes

One Ninja Foodi Max Dual Zone AF400uk Air Fryer—whether white or like mine, black—replaces several kitchen appliances at once. It’s an oven, microwave, grill, dehydrator, and steamer. Always at hand with a wide range of settings and quiet operation. Here are a couple of dishes I especially enjoyed, perfect for healthy living enthusiasts:

• Baked Trout — Insert a few lemon slices into the cleaned fish, drizzle with olive oil, sprinkle with salt and pepper, and wrap in foil. Set to 200°C for 35-45 minutes, no more.
• Soufflé Casserole — Whisk 2 eggs and 40 g of sugar, add vanilla and a pinch of salt. Separately, mix cottage cheese and 150 g of sour cream. Combine ingredients and cook in the air fryer for 10 minutes at 160°C. Then, for a crust, increase to 200°C for another 5 minutes.

These are simple, quick, and healthy meals that you can prepare every day.
