Ninja DoubleStack 8-Quart Air Fryer Review

The Ninja DoubleStack 8-Quart Air Fryer (SL201) is a game-changing innovation that completely reimagines dual-basket air fryers. Unlike traditional side-by-side models that eat up valuable counter space, Ninja's revolutionary stacked design gives you the power and capacity of two air fryers in the footprint of one. This clever vertical design is 40% slimmer than traditional 2-basket air fryers and still fits under standard kitchen cabinets. The proprietary DoubleStack Air Frying Technology features two independently controlled 4-quart baskets that deliver optimal airflow and even heat, allowing you to cook up to 4 different foods simultaneously with perfect results. With Smart Finish technology, you can cook two foods in different ways that finish at the same time, while Match Cook lets you easily duplicate settings across both zones for full 8-quart capacity meals. The included stacked meal racks add even more versatility, letting you cook on two levels within each basket. With 6-in-1 functionality, family-sized 8-quart capacity that feeds up to 6 people, and easy-to-clean dishwasher-safe components, the Ninja DoubleStack delivers exceptional performance without hogging your counter space.

Verdict
The Ninja DoubleStack 8-Quart Air Fryer is a brilliant innovation that solves one of the biggest pain points with dual-basket air fryers: their massive counter footprint. By stacking the baskets vertically instead of placing them side-by-side, Ninja has created an air fryer that delivers the capacity and flexibility of two separate units while taking up 40% less space. The DoubleStack Technology truly works — both baskets cook evenly and independently, producing consistently crispy, golden results whether you're making wings, fries, vegetables, or salmon. The stacked meal racks are incredibly clever, letting you cook proteins on top and vegetables below within the same basket, effectively giving you four cooking zones. The Smart Finish feature is a game-changer for weeknight dinners, letting you start cooking items at different times so everything finishes together hot and fresh. Match Cook makes it dead simple to double recipes across both baskets. The 8-quart capacity easily feeds a family of 4-6, and despite its generous size, it still fits under standard kitchen cabinets. Cleanup is straightforward with dishwasher-safe components. While there's a slight learning curve to master all the features, and the vertical design won't work in every kitchen, the space savings and cooking flexibility make this an outstanding choice for families who want dual-basket functionality without sacrificing precious counter real estate. If you've been eyeing a dual-basket air fryer but don't have the space, the Ninja DoubleStack is the perfect solution.
FAQ
How is the DoubleStack different from other dual-basket air fryers?
The DoubleStack is the only air fryer with vertically stacked baskets instead of side-by-side placement. This innovative design saves 40% more counter space while still providing two independently controlled 4-quart cooking zones.
Can you really cook 4 foods at once?
Yes! Each of the two baskets comes with a stacked meal rack that lets you cook on two levels. For example, you can cook vegetables on the crisper plate and protein on the rack above in each basket — that's 4 different foods cooking simultaneously.
How does Smart Finish work?
Smart Finish lets you start cooking two different foods at different times with different settings, and the air fryer automatically syncs them to finish at the same time. Perfect for when chicken needs 25 minutes but fries only need 15.
What is Match Cook?
Match Cook copies the cooking settings from one basket to the other with a single button press. It's incredibly convenient when you want to use the full 8-quart capacity to cook a large batch of the same food.
Will it fit under my cabinets?
The DoubleStack is designed to fit under standard kitchen cabinets. However, because of its vertical design, it's taller than traditional air fryers, so measure your cabinet clearance if you have lower-than-standard cabinets.
How much food can it hold?
The 8-quart total capacity (two 4-quart baskets) can cook up to 4 lbs of chicken wings total (2 lbs per basket) and feeds up to 6 people comfortably. Each basket can hold about half the food of a traditional single 8-quart air fryer.
What are the 6 cooking functions?
The DoubleStack includes Air Fry, Air Broil, Roast, Bake, Reheat, and Dehydrate functions. This versatility means you can use it for everything from crispy fries to dehydrated fruit snacks.
Is it hard to clean?
Not at all! The nonstick crisper plates are dishwasher-safe, and the baskets are easy to hand wash. The stacked design actually makes it easier to clean than side-by-side models since the baskets are more accessible.
Does it cook faster than other air fryers?
Yes! Ninja claims it cooks 2 meals faster than any other air fryer. The DoubleStack technology optimizes airflow in both baskets for faster, more efficient cooking while maintaining even results.
