Product Description:

The Ninja Double Stack XL 2-Level Air Fryer is a powerful and space-saving solution for family meals, batch cooking, and entertaining. Featuring two vertical drawers with a total capacity of 9.5L, it allows you to cook mains and sides at the same time while saving 30% more counter space than traditional side-by-side designs.

With Smart Cook System technology, the integrated digital probe monitors your food’s core temperature and stops cooking automatically when it reaches your selected doneness—perfect steaks, chicken, and roasts with no guesswork.

Use the Double Stack racks to double your cooking surface, preparing food on up to 4 levels at once with even 360° crisping airflow. Each drawer works independently with its own fan, heat source, and cooking settings, or sync both to finish at the same time.

With 6 versatile functions—Air Fry, Max Crisp, Roast, Bake, Reheat, and Dehydrate—you can cook with little to no oil for healthier meals, while saving up to 55% energy vs. conventional ovens. Designed with convenience in mind, the non-stick drawers, racks, and crisper plates are dishwasher-safe, making cleanup effortless.
