Ninja vs Cosori Air Fryer — Which Should You Buy?

The Two Most Recommended Family Air Fryers

The Ninja AF101 and the Cosori Pro II 5.8-Qt are the two air fryers I recommend most frequently. They sit at different points on the capacity and price spectrum, and the right one depends almost entirely on how many people you’re cooking for and how often.

I tested both for months in my kitchen, often side by side. Here’s everything I found.

Head-to-Head Comparison

Capacity: Cosori Wins, But Size Matters

This is the most important comparison and the one most buyers underestimate. 4 quarts vs 5.8 quarts isn’t just a number difference — it’s the difference between cooking for four people in one batch or two.

For a family of four, the Ninja AF101 handles boneless chicken, chips, vegetables, and fish in one batch. For bone-in pieces like thighs or drumsticks for four people, you’ll often need two batches. For five people, batch cooking is the norm rather than the exception.

The Cosori Pro II’s 5.8-quart square basket comfortably holds four large bone-in thighs or five boneless pieces in one go. For a family of four cooking bone-in cuts nightly, this removes the most frustrating part of the Ninja AF101 experience.

Winner: Cosori Pro II — but only matters if you’re cooking for 4+ regularly.

Cooking Performance: Effectively Equal

Both air fryers produce excellent food. After months of testing both, I can’t reliably taste the difference in a blind comparison of chicken thighs, chips, salmon, or roasted vegetables cooked at the same temperature and time.

The Cosori’s 230°C ceiling vs the Ninja’s 205°C does produce marginally crispier results on chicken wings and battered items at maximum temperature — but it’s a minor difference that most families won’t notice in everyday cooking.

Winner: Draw for 95% of family cooking. Cosori marginally ahead for high-heat crispy applications.

Presets: Cosori by a Distance

The Ninja has four functions: Air Fry, Roast, Reheat, Dehydrate. These do the job, but you’ll be manually setting temperatures and times for everything.

The Cosori has 12 presets — Chicken, Chips, Steak, Seafood, Bacon, Frozen Foods, Bread, Pizza, Cake, Vegetables, Reheat, and Dehydrate — each with calibrated temperatures and times that actually work. The VeSync app adds 100+ guided recipes and a shake reminder mid-cook.

For a family new to air frying, the Cosori’s presets reduce the learning curve significantly.

Winner: Cosori Pro II — if you value guided cooking. The Ninja is fine if you’re happy setting things manually.

Cleanup: Effectively Equal

Both baskets clean in under two minutes by hand or go in the dishwasher. I tested both with identical meal types across eight weeks and found no meaningful difference in cleanup time or difficulty. The Cosori’s ceramic coating releases fattier foods (bacon, duck) slightly more cleanly than the Ninja’s non-stick, but the difference is marginal.

Winner: Draw.

Build Quality and Durability

Both held up well over months of daily use. The Ninja’s non-stick basket showed no peeling or scratching after three months and 67 uses including regular dishwasher cycles. The Cosori’s ceramic coating showed no degradation after eight weeks of daily use. I’d expect both to last 2–4 years of regular family use with proper care.

The Ninja feels slightly more solidly constructed — the basket slides in and out with a more satisfying click. The Cosori’s basket fits securely but the mechanism feels slightly lighter.

Winner: Slight edge to Ninja AF101 on pure build feel.

Price: Ninja Wins

The Ninja AF101 at ~£70 is £20–40 cheaper than the Cosori Pro II, depending on sales. For families where the smaller capacity isn’t a limitation (2–3 people), that £20–40 is better spent elsewhere.

Winner: Ninja AF101.

Frequently Asked Questions

Is the Ninja AF101 or Cosori Pro II easier to use?

Both are straightforward, but the Ninja is simpler — four functions, a dial, done. The Cosori has more options, which means slightly more decision-making. For someone who wants to press one button and walk away, the Cosori’s presets actually make it easier for common meals. For someone who prefers minimal controls, the Ninja wins on simplicity.

Which air fryer lasts longer — Ninja or Cosori?

Based on my testing and long-term reports from other family cooks, both are comparably durable. Both brands have good customer support within their warranty periods. I’d expect similar lifespans of 3–5 years with daily use.

Can I cook the same foods in both?

Yes — everything you can cook in the Ninja, you can cook in the Cosori and vice versa. The Cosori can cook slightly larger quantities and at slightly higher temperatures, but no food type is exclusive to either model.

Is the Cosori Pro II worth the extra money over the Ninja?

For families of four or more who cook with the air fryer daily, yes — the extra capacity alone justifies the price difference. For families of two to three, or families who use the air fryer three or four times a week rather than daily, the Ninja AF101 is the better value.
