7 Best Ninja Air Fryer Ovens for Every Kitchen

The Prestige Smart XL is the Ninja oven we would put on most counters. It preheats in 90 seconds, fits 20 cookies or 9 slices of toast on a rack, and turns out two pizzas at a time or a tray of baked potatoes without heating the whole house in summer.

The fan runs hard on every function, bake and toast included, and it is loud enough that you may wonder whether something is wrong, though it won't wake a napping child next door. The fan sits behind a sealed rear enclosure with no access panel, so protect it by wiping splatter off the back wall after cooking greasy food. The top panel also gets hot, so set a heat-safe board on it before you store anything up there.

If the Prestige Smart XL is the all-rounder, the Foodi XL Pro is the batch cooker. It handles two sheet-pan meals at once and is strong on fish, whole roast chicken and reheated leftovers, which makes it our pick for families of five or more.

It is not the fastest crisper. Chicken nuggets take about 10 minutes at 450°F and bacon takes 15 to 17 minutes, a little slower than a basket air fryer, while garlic bread is done in about 3 minutes. The toast cycle runs a fixed time no matter how hot the oven already is, so set a lighter shade for the second batch. The nonstick pans and basket are the first parts to wear, lasting roughly a year of frequent use.

Where the DT201 goes big, the SP101 goes low. Its roughly 3-inch cavity is a hard limit, so a tall pile of nachos has to be pressed down and a whole chicken does not fit comfortably. Accept that, and it is the best value in Ninja's lineup. Toast browns evenly across the whole tray, frozen tater tots come out crisp outside and fluffy inside, and it holds within about 7 degrees of the set temperature.

In use it needs about 19 by 15 inches of counter, and flipped up it shrinks to about 19 inches tall by 7 inches deep. Need more height? The SP201 is the extended-height version. It fits a 2-lb roast or a 9x13 pan and reaches 400°F in about a minute, though you have to pull the base toward you before flipping it upright.

The SP151 takes the SP101's flip-up idea and adds six infrared heating elements with an 85°F to 450°F temperature range. In a small kitchen, flip-up storage is a genuine game-changer, because your prep space comes back the moment dinner is done. Preheat is consistently under a minute, the wide, shallow chamber browns single-layer fries, wings and Brussels sprouts evenly edge to edge, and a baked potato is done in about 25 minutes.

Toast is its weakest job. Six slices on the darkest setting take about 3 minutes 40 seconds, and the underside can darken before the top browns, so flip the slices or move the rack. At close to 20 lbs, flipping the oven up is a two-handed move, and it needs a backsplash behind it, so an island spot defeats the feature.

Where the flip-up models shrink the oven, the DCT451 doubles it. The top oven handles toast and reheating while the bottom oven crisps and roasts. Fries crisp up well below while a casserole bakes evenly and comes out piping hot, and toast is consistent wherever the slice sits. Smart Finish holds the faster oven so both finish together, which takes a little learning.

At about 31 lbs, it stays where you put it, so choose its spot before you unbox it. Both cavities drop crumbs and grease onto the same tray, so empty it after every greasy cook rather than letting it build up over a week.

The DT551 is the same oven as our top pick, with the probe. The Pro Cook System thermometer cooks a prime rib to the chosen doneness reliably, and a 5-lb roast cooks without issue. It is a capable baker too, with two wire racks that hold at least 24 full-size cupcakes. Two adjustments help with baking: allow a few extra minutes of preheating for cakes because the beep sounds before the cavity is fully hot, and use Reheat as a fan-free setting for delicate bakes. Bake mode itself is fairly quiet.

It ranks below its twin because of one known fault, most often traced to a broken wire at the door hinge. Earlier Smart XL generations lasted about three to four years with near-daily use, so keep your receipt.

The FO101 solves the problem the flip-ups can't: height. It takes a prime rib or a full-size frozen pizza, and the included 5-qt basket holds up to 5 lbs of fries. Both doors swing open together with one pull, handy with a hot tray in the other hand, and cookies spread and brown evenly across the sheet pan. Keep an eye on the first few cooks, since heat can run hotter than the dial says.

Ninja's dishwasher guidance for the basket is inconsistent, so we would hand-wash it. For parts, it is the best supported oven here: Ninja lists a replacement basket, rack and crumb tray, though stock comes and goes.
