Ninja Double Stack XL SL400EU Air Fryer is a modern dual-zone air fryer designed to cook large meals while saving kitchen counter space. Its distinctive vertical “double stack” layout places two independent cooking drawers on top of each other instead of side by side, giving you a generous 9.5-liter capacity in a slimmer footprint.
The appliance features two separate cooking zones that can operate at different temperatures and times simultaneously, making it easy to prepare complete meals together — for example, crispy fries in one drawer and chicken in the other. With Ninja’s SYNC function, both drawers can finish cooking at the same time, while MATCH mode lets you duplicate settings across both zones for larger batches.
The SL400EU offers multiple cooking functions including Air Fry, Roast, Bake, Reheat, Max Crisp, and Dehydrate. It uses rapid hot-air circulation technology to create crispy textures with little to no oil, providing a healthier alternative to deep frying.
Its gray finish and compact vertical design give it a sleek, contemporary appearance suitable for modern kitchens. The drawers, crisper plates, and racks are removable and dishwasher-safe for easier cleaning.
