Ninja Air Fryer Review

If you're looking for a dedicated air fryer, the Ninja Air Fryer provides exceptional results and a great overall experience. It has a 4-quart capacity and scored the highest of all the air fryers I've tested for temperature accuracy.

Cooking Quality

During my extensive cooking tests, I evaluated the Ninja Air Fryer across three key categories: frozen foods (tater tots and fries), proteins (chicken wings and salmon), and overall texture. The results revealed a machine that excels at creating crispy exteriors while maintaining moisture inside—the holy grail of air frying.

Fries and Tater Tots

For the tater tot and french fry test, I was looking for that perfect combination of a shatteringly crispy exterior (think Lay's potato chip, not hard and crunchy ends that assault your mouth) paired with a fluffy, cloud-like interior. The Ninja delivered.

After a 3-minute preheat—which I found essential despite not being strictly required—the tater tots emerged with beautiful golden-brown coloring and that sought-after textural contrast. The exterior shattered satisfyingly when bitten, revealing a light, fluffy interior that avoided any mushiness or mealiness. The Ninja struck an excellent balance between a crispy exterior and a moist interior texture.

Chicken Wings

Chicken wings presented a more complex challenge, requiring the air fryer to render fat effectively while crisping the skin without drying out the meat. I used a modified recipe with baking powder and spices, cooking at 400°F for 15-18 minutes with flips every 5 minutes.

The Ninja produced wings with pretty good browning and notably juicy meat. When I bit into them, the meat actually glistened, indicating excellent moisture retention. The skin achieved a nice crisp, though I'd describe it as lighter than some competitors. Still, these wings would satisfy most air fryer enthusiasts looking for a healthier alternative to deep-fried wings.

Salmon

The salmon test truly showcased the Ninja's capabilities. I achieved a lovely soft texture with crispy skin and good browning throughout. The fish maintained its moisture beautifully, coming very close to the performance of higher-end models.

Previous Next

The skin crisped up nicely while the interior remained tender and flaky—exactly what you want from air-fried salmon. This performance suggests that the Ninja handles delicate proteins as well as it does frozen convenience foods. All told, the salmon I tasted from this machine was delicious.

Cooking Speed

Speed matters when you're hungry, but consistency matters more. The Ninja Air Fryer strikes a reasonable balance between the two. During my testing, I found it requires a 3-minute preheat for optimal results, followed by cooking times that align closely with recipe recommendations. The chicken wings took 15 minutes after preheating, while the salmon reached a perfect 145°F internal temperature in just 12 minutes post-preheat.

What impressed me most wasn't its raw speed but rather the predictability. Unlike some ultra-fast models that risk burning food if you follow standard recipe times, the Ninja cooks at a pace that matches most air fryer recipes. This means you can trust that 10-12 minute recipe to actually take 10-12 minutes (plus preheat), reducing the guesswork and frequent checking that plague some models. I always recommend checking food a couple minutes before the recipe's stated time, but with the Ninja, I rarely found food overcooked when following standard guidelines.

Temperature Accuracy

Temperature accuracy can make or break an air fryer's performance, so I subjected the Ninja to rigorous testing using a 4-channel thermometer, logging data every 6 seconds over 25 minutes.

The results were impressive: when set to 400°F, the unit maintained an average temperature remarkably close to the target, deviating by only about 3.2 degrees on average.

More importantly, the Ninja avoided the wild temperature swings that plague many air fryers. While some units technically hit their target temperature but oscillate by 30+ degrees throughout the cooking cycle, the Ninja stayed within a tight 15-degree range. This consistency explains why my food came out so evenly cooked—no hot spots, no undercooked sections, just reliable results batch after batch.

The external temperature reached 146°F during operation, just slightly above my 140°F safety threshold. While you should still exercise caution, this relatively cool exterior makes it safer than many competitors, which is especially important in cramped kitchens where the unit might be positioned close to other items.

Ease of Use

Simplicity reigns with the Ninja Air Fryer's interface, which uses physical buttons rather than touch controls. I appreciate this choice since physical buttons provide tactile feedback and work reliably even with wet or greasy fingers. The interface includes straightforward controls for temperature, time, and cooking modes.

However, the temperature control system frustrated me throughout testing. The unit adjusts temperature in irregular increments ranging from 5 to 15 degrees, making precise control difficult. When I needed 370°F for a specific recipe, I had to choose between 360°F or 375°F. While 5 degrees rarely ruins a dish, this lack of precision feels like an unnecessary limitation in an otherwise capable machine.

The Ninja offers four cooking modes: Air Fry (300-400°F), Roast (250-400°F), Reheat (270-400°F), and Dehydrate (105-195°F). These aren't food-specific presets but rather heat distribution patterns, which I actually prefer—it encourages you to understand how the machine works rather than blindly trusting a “frozen fries” button. The included recipe book helps bridge the knowledge gap for beginners.

Notable absences include an automatic pause when removing the basket (requiring manual pausing before checking food) and any shake reminder system. During my wing testing, I had to set separate timers to remember the every-5-minute flips. These aren't deal-breakers, but they do make the cooking process slightly less convenient than that of some competitors.

Cleaning proved refreshingly simple. Both the crisper plate and basket are dishwasher safe, though the manufacturer recommends hand washing to extend their lifespan. I found hand washing easy enough—the PTFE-free ceramic coating released food readily, and the compact size made maneuvering in the sink simple. Even after cooking greasy wings, a quick scrub with warm, soapy water restored the basket to like-new condition.

Should You Buy The Ninja Air Fryer?

The Ninja Air Fryer makes sense for singles, couples, or anyone with limited counter space who value consistent results over bells and whistles. Its 4-quart round basket (8.25" x 8.25") provides 53.5 square inches of cooking surface—enough for a meal for two or sides for four. If you prioritize straightforward operation, reliable temperature control, and easy cleaning over advanced features like dual baskets or smartphone connectivity, this model delivers excellent value. The PTFE-free cooking surface also appeals to health-conscious users avoiding traditional non-stick coatings.

What Other Air Fryers Should You Consider?

If you need more capacity for family meals or entertaining, consider the Cosori TurboBlaze. This model was a favorite for its large capacity, offering significantly more cooking space while maintaining excellent temperature accuracy and cooking performance for vegetable-based dishes, fish, and poultry.
