The Ninja Double Stack XL 9.5L Air Fryer SL400 is a space-saving, high-capacity air fryer designed with an innovative vertical stacking system that allows you to cook multiple foods at once without taking up extra countertop space. It combines dual-zone cooking flexibility with a compact footprint, making it ideal for kitchens where space efficiency is important.
A defining feature of this model is its Double Stack design, which includes two vertically stacked drawers instead of the traditional side-by-side layout. This configuration provides a total 9.5 L capacity, allowing you to cook large portions or multiple dishes simultaneously while reducing the appliance’s overall width on the countertop.
Each drawer operates as an independent cooking zone, giving you full control over time, temperature and cooking function in each compartment. This makes it possible to prepare different foods at the same time without flavor transfer or compromise in cooking performance.
The SL400 offers 6 versatile cooking functions:
-
Air Fry – for crispy results with little to no oil
-
Max Crisp – high-temperature cooking for frozen foods
-
Roast – ideal for meats and vegetables
-
Bake – for cakes, pastries and desserts
-
Reheat – warms leftovers evenly
-
Dehydrate – for drying fruits, vegetables and snacks
To enhance flexibility, the air fryer includes Dual Zone Technology with two key features:
-
SYNC Mode: ensures both drawers finish cooking at the same time, even when using different settings
-
MATCH Mode: applies identical settings across both drawers for larger quantities of the same food
The appliance uses powerful convection airflow to circulate hot air evenly around food, creating a crispy exterior while maintaining a tender interior. This method allows cooking with significantly less oil compared to traditional frying methods.
Inside each drawer, stackable cooking racks allow you to cook on multiple levels within a single zone, effectively increasing cooking capacity without increasing the appliance size. This is especially useful for preparing layered meals or maximizing output in one cycle.
The digital control panel is designed for ease of use, providing clear access to cooking functions, temperature adjustments and timers. Each zone can be controlled independently for precise cooking results.
For convenience, the drawers and crisper plates feature a non-stick coating and are dishwasher-safe, making cleanup simple. The unit also includes non-slip feet for stability during operation.
The Ninja Double Stack XL SL400 is suitable for preparing a wide variety of meals, including:
- Chicken, fries and frozen foods
- Roasted meats and vegetables
- Baked goods and desserts
- Dehydrated snacks
- Multi-layer meals using stack racks
