Cooking Performance

To evaluate top air fryers, I prioritize cooking performance. As a kitchen appliance editor and experienced cook, I carefully assess each model using frozen French fries, chicken wings, and roasted veggies. For my initial test with the Ninja Double Stack, I followed a recipe in the manual that included familiar ingredients.

Test 1: French Fries

The recipe instructed cooking fries for 20 minutes, with guidance to shake the basket periodically. Initially, this seemed excessive, but I was pleased with the results. At the 15-minute mark, the fries were golden, with a few at the back slightly lighter. I opted to finish early, and the outcome was remarkable.

These fries rivaled restaurant quality—crispy outside and fluffy inside. My partner declared them the best homemade fries he's ever tasted, which is high praise given our frequent frozen fry consumption.

Test 2: Chicken Thighs

I added some green vegetables to the bottom drawer, placed the rack on top, and arranged two chicken thighs. Using the preset for Air Fry for 20 minutes yielded chicken with a crispy, slightly charred skin, which was flavorful. While the meat was juicy, I prefer it a bit more tender, as oven-cooked thighs tend to be.

Test 3: Roasted Vegetables

The combination of green beans and zucchini in the lower drawer came out beautifully caramelized, resembling slow-roasted vegetables. However, the same ingredients on the rack yielded inconsistent results, with some zucchini charred while others remained pale. This may have been due to insufficient shaking, as slices slipped through the grates.

Test 4: Sausages

I prepared sausages on the rack, encountering similar uneven cooking issues. The front of the drawer clearly received more heat, but by rearranging and flipping the sausages, I achieved a delicious golden finish. Typically, this level of crispiness takes me 40 minutes in an oven, but the Ninja achieved it in just 15 minutes, making it a win in my book.

Test 5: Special Features

The Ninja Double Stack XL includes six versatile functions: Air Fry, Max Crisp, Roast, Bake, Reheat, and Dehydrate, offering extensive cooking options. The Air Crisp feature provides an extra crunch for battered foods. I tested it on chicken strips and was thoroughly impressed.

Using the Bake function, I made a Chocolate Peanut Butter Brownie recipe from the manual. The brownies turned out thin and fudgy rather than gooey like traditional oven-baked versions, but the convenience was undeniable. With no preheating required, I could fill both baskets with batter and create roughly 20 slices for guests.

User Experience

Ninja prioritizes user-friendliness in design. The instruction manual is excellent, filled with recipes, meal plans, and temperature settings, allowing for stress-free cooking. The display panel may not be high-tech, but it's functional and easy to operate.

The 'match' and 'sync' features enhance usability. After setting the time and temperature for Basket 1, the 'match' button duplicates those settings for Basket 2. The 'sync' option allows for different cooking times, ensuring everything finishes together for serving.

Although there are no preset recipes on the panel, a convenient sticker provides essential cooking times and temperatures for various foods. Keep it handy, as losing it may leave you without guidance.

A pair of silicone tongs is essential for this air fryer, as the metal racks can be hot. Thankfully, I have a set among my must-have air fryer accessories.

Capacity

Whether cooking for many or just yourself, the 10-quart capacity of the Ninja Double Stack Air Fryer is substantial. Ninja claims it can serve up to eight people and handle up to 10 pounds of chicken wings. It works perfectly for my partner and me, and I've used it while hosting two additional guests.

The manual mentions fitting a 5-pound chicken in one drawer, which I find questionable given the narrow size. For larger cuts, I suggest considering the Foodi FlexBasket.

Cleaning Ease

Cleaning the Ninja Double Stack Air Fryer is straightforward, with removable, dishwasher-safe parts that are easy to hand wash. The ceramic non-stick coating on the crisper plates allows for simple wipe-downs with soapy water and a soft sponge.

Ninja's popularity means you can find various compatible basket liners on Amazon. These liners significantly streamline cleaning and can prolong the life of your air fryer. I particularly like the silicone liners that fit perfectly in each basket.

The exterior, featuring a matte finish and silver accents, resists fingerprints, making it easy to keep looking pristine.

Design & Build Quality

The construction of the Ninja Double Stack Air Fryer instills confidence. It's narrow yet stable and sturdy, with a cool-touch exterior and non-slip feet for added safety, ensuring it stays put on your countertop.

Customer Feedback

Reviews for the Ninja Double Stack XL are generally favorable, boasting a strong 4.5-star rating on Amazon. Users praise its ability to create crispy fries, ease of family meal preparation, and hassle-free cleanup. Some reviewers express concerns regarding the price and uneven browning previously noted.

While one reviewer appreciated the non-toxic ceramic coating on the crisper plates, they were disappointed by the PTFE coating in the drawers. If you're cautious about non-stick surfaces, rest assured they are generally safe with proper care, ensuring your air fryer remains durable over time. For more information on non-toxic cookware, see my feature on safe cooking options.

Final Thoughts

The Ninja DoubleStack is a significant investment, but I believe it's worth it for those seeking a large air fryer. With its 10-quart capacity, it can accommodate a crowd while maintaining a sleek appearance. It produces the crispiest French fries I've ever made, and I can overlook the occasional uneven browning because of its ease of use and cleanup. I highly recommend it for families and compact kitchens.

Our Testing Methodology

To evaluate the best air fryers available, I focus on outstanding cooking performance. As an experienced cook and kitchen appliance editor, I rigorously assess each model by frying frozen French fries, chicken wings, and roasted vegetables. We seek perfectly crispy exteriors and tender interiors during our taste tests, comparing results against industry standards.

User-friendliness is crucial in air frying. My evaluations also consider how intuitive the controls are, the design of the basket, the quality of the instruction manual, and the accuracy of recipe presets. I explore any unique features like grilling and dehydrating to judge versatility. Throughout the cooking process, I take notes on capacity since it's essential for family-sized air fryers.

Cleaning can be tedious, so I assess how easy it is to wash removable parts, both by hand and in the dishwasher. I also check the materials for safety and durability. Post-testing, I research customer reviews to gauge the air fryer's reliability and overall satisfaction.

Finally, when investing in a kitchen appliance, price is significant, so I evaluate features and performance to determine if it offers good value. Our goal is to ensure you select an air fryer that not only looks stylish in your kitchen but also delivers reliability and efficiency.
