Looking for a double air fryer but short on counter space? The Ninja Double Stack XL 9.5L 2-Drawer Air Fryer is designed to save space without sacrificing capacity.
With two vertically stacked drawers, it takes up less room than traditional side-by-side air fryers while still offering plenty of cooking space. Each drawer has its own controls, so you can cook mains and sides at the same time, using different functions, times and temperatures – all perfectly synced to finish together.
This air fryer is 30% slimmer* yet can still fit a 1.4kg roast chicken in each 4.75L drawer, making it ideal for large families or entertaining up to 8 people. At 38.5cm tall, it easily fits under most kitchen cabinets, keeping your counters clutter-free.
Thanks to Double Stack Air Fry Technology, you can cook on four layers at once using the included stacked meal racks. Each drawer has its own heat source and fan, circulating hot air evenly for crispy, golden results across all levels. Prepare full meals in one go – chicken with vegetables, salmon with potatoes, burgers with fries, or a spread of party food.
With six versatile functions – Air Fry, Max Crisp, Roast, Bake, Dehydrate and Reheat – you can make everything from crispy chips to baked treats. It cooks up to 55% faster than fan ovens**, using up to 55% less energy†. For smaller portions, you can use just one drawer.
The control panel is positioned on the side for easy access, with simple one-touch settings. When the timer finishes, cooking stops automatically. You’ll also get a recipe guide with chef-created ideas and cooking charts to help you get started.
Cleaning is simple too – the non-stick drawers, crisper plates and racks are all dishwasher safe. For added reassurance, Ninja provides a 2-year guarantee upon registration (UK & ROI only).
