Ninja DZ401 vs Cosori TurboBlaze: Which Should You Buy in 2026?

Air fryers became a permanent kitchen fixture sometime around 2022, and the market has only gotten more competitive in 2026. Two models keep coming up at the top of every “best of” list: the Ninja DZ401 Foodi 10 quart dual basket and the Cosori TurboBlaze 6 quart single basket. They take very different approaches. Ninja gives you two independent baskets that finish their food at the same time. Cosori gives you one larger basket with a more powerful DC motor and five fan speeds. We tested both for crispiness, capacity, ease of cleaning, noise, energy use, and value, then broke down which one fits which kitchen. Read on for the full breakdown.

Side by Side Specs

Capacity and Real World Cooking

The Ninja DZ401 has a clear capacity advantage on paper. Ten total quarts split between two five quart baskets is a serious amount of food. You can fit a four pound chicken in one basket, two pounds of fries or vegetables in the other, and have them finish at the same time using Smart Finish. For Sunday dinners, weeknight family meals, and meal prep cooks, this is a huge time saver. No more cooking the protein, then putting it under foil while the side dish runs through the same machine.

The Cosori TurboBlaze has a six quart single basket. That sounds smaller, but the basket geometry actually fits a whole five and a half pound chicken with room to spare. You can also fit a 12 inch pizza, a one pound bag of fries, or six chicken breasts in a single layer. For a household of one or two, six quarts is plenty. For a family of four, the TurboBlaze can handle it but you may need to cook proteins and sides in separate batches.

Real world test: cooking a four pound bag of frozen French fries plus eight chicken thighs. The Ninja DZ401 finishes everything in 22 minutes, both items perfectly done at the exact same moment. The Cosori TurboBlaze takes 34 minutes total because the chicken and fries cook in two separate batches. If your weeknight schedule is tight, the Ninja saves real time.

Crispiness and Cooking Performance

Crispiness is where the Cosori TurboBlaze flexes hard. The DC motor with five fan speeds and that 3,600 rpm top speed delivers more even airflow than just about any single basket air fryer at this price. French fries come out shatter crisp on the outside and pillowy soft inside. Chicken wings render fat better and develop a deeper brown crust. Frozen foods like dumplings or tater tots get golden in 8 to 10 minutes flat.

The Ninja DZ401 is no slouch. The dual basket design uses a smaller fan in each basket, so airflow is intense in a more contained space. Crispiness is excellent, just slightly less uniform than the TurboBlaze on items where every piece needs the same exact crisp. Things like wings and potatoes still come out great, but you may need to shake the basket once during the cook for the most even results.

If you have ever felt that some pieces in your air fryer come out crispier than others, the TurboBlaze will likely impress you. If you mostly cook in larger batches and accept a quick mid cycle shake, the Ninja delivers more food faster.

Cooking Functions and Versatility

The Cosori TurboBlaze offers nine functions including Proof and Keep Warm, which the Ninja does not. The Frozen mode is calibrated specifically for cooking frozen foods without thawing, and that comes in handy for weeknight dinners. The 90 degree low setting is also lower than the Ninja’s 105 degree minimum, which matters for slow dehydration of fruits or making jerky.

The Ninja DZ401 has six functions but adds the killer feature of dual zone cooking. Match Cook duplicates settings across both baskets when you want to cook 10 quarts of one food. Smart Finish syncs the timing so that two different foods finish at the same time even if one needs longer. That dual zone capability has more day to day value for most families than the extra functions on the Cosori.

Ease of Cleaning

Both units have ceramic nonstick coatings that release food cleanly. Both have dishwasher safe baskets and crisper plates.

The Cosori TurboBlaze gets a small edge here because the PFAS free ceramic coating tends to last longer than competitor coatings, and the basket is large enough that you can wipe it down easily without battling corners. There is also less surface area to clean compared to two separate Ninja baskets.

The Ninja DZ401 has two baskets to clean. They go in the dishwasher, but if you handwash, that is roughly twice the work. The crisper plates are also two pieces. Plan an extra two minutes of cleanup compared to the Cosori.

Noise Level

The Cosori TurboBlaze runs noticeably quieter on the lower fan speeds and slightly louder on speed five at full blast. Average noise across a typical cook hovers around 60 to 65 decibels.

The Ninja DZ401 runs at a consistent 65 to 70 decibels through the entire cook because the AC motors do not modulate. Not loud enough to be annoying, but more present in an open kitchen layout than the Cosori on its lower speeds.

Footprint and Counter Space

The Ninja DZ401 is a counter hog. At 15.6 x 13.9 inches plus the height clearance you need to open the baskets, it takes a real chunk of counter or pantry storage. If you have limited counter space, this matters.

The Cosori TurboBlaze is dramatically smaller at 11.8 x 14.4 inches, and the lid swings open vertically so you do not need much rear clearance. It fits in apartment kitchens, RVs, and tight counters where the Ninja just will not.

The Bottom Line

If you have a family or you cook two foods at once on a regular basis, the Ninja DZ401 is the obvious pick. The dual basket design is genuinely a game changer once you start using it, and the time savings on busy weeknights are real. If you cook for one or two, want the absolute best crisp on a single basket, prefer a smaller footprint, and care about PFAS free materials, the Cosori TurboBlaze is the smarter buy and saves you about $80 in the process.

Both units are top tier in 2026. The right one depends entirely on your household size and counter space. There is no wrong answer between these two air fryers, only a wrong fit.
