Ninja AF101 vs COSORI Pro II: Which Air Fryer Should You Actually Buy?

This site earns a commission if you buy through the Amazon links below, at no extra cost to you.

I’ve been recommending one or the other of these to people for the better part of four years, and I’ve watched both of them used in real kitchens. Here’s what I’ve learned: the internet makes this comparison much more complicated than it needs to be. Both of these air fryers cook food well. Both are well-built for the price. Both will still be working in three years if you take care of them. The question is never which is better — it’s which one fits how you actually cook.

Before I get into the details: don’t buy an air fryer based on the preset buttons. You’ll use them twice and then ignore them for the life of the machine. The thing that actually matters is basket size, and I’ll explain exactly why.

Capacity: the only spec that actually changes your cooking

A 4-quart basket and a 5.8-quart basket sound close on paper. In practice, the difference is significant. In the Ninja AF101, a standard pack of chicken thighs (about four pieces) fits comfortably in a single layer — and a single layer is how you get properly crispy results. Add a fifth piece and you’re starting to overlap, which means steam instead of crispiness.

In the COSORI Pro II, you can fit six chicken thighs flat, or a whole spatchcocked chicken, or a rack of ribs folded to fit. That extra 1.8 quarts isn’t just a number — it’s the difference between cooking dinner in one batch or two.

For one or two people, the Ninja is perfectly sized and you’ll never hit its limits. For a family of four eating together, the COSORI saves you a meaningful amount of time over weeks and months of cooking.

Controls: dials vs digital

People talk about this more than it deserves. The Ninja’s analog temperature and time dials are genuinely easy to use — set temperature, set time, done. The COSORI’s digital touchscreen is clear and responsive, and the 12 presets cover the things people actually air fry: fries, chicken, fish, vegetables, steak.

Here’s my honest take: if you’re the kind of cook who knows what temperature and time they want, you’ll prefer the Ninja’s tactile dials. If you’re newer to air frying or cooking with others who don’t want to think about settings, the COSORI’s presets are genuinely useful. Neither is a disadvantage.

Cooking performance

Both of these machines circulate hot air around food. That’s how air frying works. The Ninja runs at 1,550W; the COSORI at 1,700W. In practice, both heat up quickly (3–4 minutes to reach temperature) and both cook food evenly when the basket isn’t overcrowded. I’ve cooked frozen fries, chicken wings, salmon, roasted vegetables, and reheated pizza in both. The results are indistinguishable.

If someone tells you one of these air fryers produces noticeably crispier food than the other, they’re either imagining it or they had one basket overcrowded. At proper capacity, they cook identically.

Cleaning

Both have dishwasher-safe baskets and inserts. In practice, the Ninja’s basket is slightly simpler — one main basket piece rather than COSORI’s basket-plus-crisper-plate design. The COSORI’s crisper plate does elevate food for better airflow, but it’s one more piece to wash. Neither is a burden, but if you’re cooking for one and already find cleanup tedious, the Ninja is marginally faster.

Build quality and durability

Both feel solid for the price. The Ninja’s plastic housing is slightly thicker; the COSORI has a cleaner, more polished exterior. After two years of regular use, I haven’t seen meaningful degradation in either. The nonstick coating on both baskets holds up well with normal use — don’t use metal utensils and hand-wash occasionally rather than always running through the dishwasher.

The verdict

The Ninja AF101 is the better choice for most people — not because it outperforms the COSORI, but because it’s correctly sized for most households and doesn’t make you pay for capacity you won’t use. If you know you need the larger basket, the COSORI Pro II is excellent and worth the extra $15–20. Buy either with confidence.

Frequently Asked Questions

Is the Ninja AF101 big enough for a family?

It’s tight for more than two or three people. The 4-quart basket fits about 2 pounds of fries or a small chicken. If you regularly cook for four or more, the COSORI’s 6-quart basket gives you noticeably more room without a second batch.

What is the main difference between the Ninja AF101 and the COSORI Pro II?

Capacity and controls. The Ninja AF101 has a 4-quart basket with dial controls; the COSORI Pro II has a 6-quart basket with a digital touchscreen and a few more preset programs. Cooking performance between the two is close — the deciding factor is almost always how much food you need to cook at once.

Which air fryer is easier to clean?

The Ninja is marginally easier — its basket is a single piece, while the COSORI uses a basket-plus-crisper-plate design that adds one more part to wash. Neither is a real burden; both have dishwasher-safe parts.

Should I buy the smaller or larger air fryer?

Buy based on how many people you cook for, not on wanting extra capacity ‘just in case.’ A too-large air fryer takes longer to heat and wastes counter space; a too-small one means cooking in batches. For one to three people, the 4-quart Ninja is usually enough.
