About this product
Wish you could fit a double air fryer in your kitchen, but running low on worktop space? Introducing the Ninja Double Stack XL 2-Drawer Air Fryer. This stacked air fryer is 30% slimmer without compromising on capacity – perfect for smaller kitchens, large families and entertaining. With 2 independently controlled drawers, you can mix and match different cooking functions, times and temperatures in each drawer – both finish cooking at the same time with the Sync function.
Cook 4 foods at the same time: Simply insert one of the included Stacked Meal racks into each drawer for 2x capacity. Rear fans ensure food is evenly cooked and crisped on All 4 levels, so you can cook chicken tenders in the same drawer as fries, salmon in the same drawer as asparagus, or the ultimate combo of party foods.
Extra-large capacity: Easily fit a whole 1.4kg roast chicken in each 4.75L drawer. At 38.5cm tall, it's designed to fit under cabinets. 6 cooking functions: Air Fry, Roast, Bake, Dehydrate, Reheat, and cook from frozen to extra-crispy with Max Crisp.
Cook up to 55% faster than fan ovens(tested against fish fingers and sausages). Easy to clean: Non-stick drawers, crisper plates and wire racks are all dishwasher-safe. Ninja offers a free 2-year guarantee upon registration (UK & ROI only).

Great versatility and constant results
I'm on my third air fryer but first ninja. This is a far superior machine compared to my past purchases. Plenty of features and so easy to use. Food is always excellent and the max crisp feature is great for chicken and chips etc. it easily has capacity for the whole family. Id definitely recommend paying slightly more for this machine for the consistency and versatility.

Neat, compact Airfryer
I bought this Airyfryer to replace the previous one which suddenly ceased to work just after Christmas 2025. I liked my original one so decided to order the same model. I really like the compact size of this particular Ninja - it fits neatly on worktop, under the above cupboards. It has got a really good capacity - it can easily take a large chicken in one compartment, with potatoes and stuffing in the other compartment. It crisps up really well too - I reheated the roast potatoes and they came out perfect. A very versatile product.

Cooking just got a whole lot easier
I bought this because I can’t cook, I had noticed that Iceland sell items with cooking instructions specifically for Ninja. It’s fantastic I recommend you buy one of these, particularly if like me cooking is not your forte

Well Pleased.
Up to now after a few days of using it and a few test runs, all is good and I am very pleased with my purchase.
