Best Air Fryer for Frozen Food: Fries, Nuggets, and the Shake Rule
I’ve tested every air fryer the same way for years, and the frozen food test is the one that tells me the truth fastest. You can bake a perfect chicken thigh in a machine that runs 25 degrees hot, but you can’t hide a soggy fry. The Cosori TurboBlaze is the best air fryer for frozen food I’ve tested, because it’s the only one that nails the “Shake Rule” without me having to babysit the basket.
The Cosori TurboBlaze (B0C33CHG99) is the best air fryer for frozen food I’ve tested, because it preheats properly, holds temperature within 5 degrees, and the ceramic basket releases even the most stubborn frozen cheese stick without a fight.
I bought mine for $85 on Prime Day, and I’ve since bought three more as gifts. The frozen fry test came out crispy in 12 minutes at 400°F. The cake test revealed no hot spots, which is rare. The chicken thigh crisp test passed with skin crackling and meat cooked through to 165°F. It’s quiet enough that I have to check if it’s even on.

Pros
- Quiet. I have to check if it’s even on. This is the first thing I test, and it’s the reason I use this machine daily.
- Ceramic coating releases even melted cheese with ease. The basket is dishwasher-safe.
- The preheat feature actually works. I set it, it beeps when ready, and the cook time starts accurate.
- The recipe book that comes with it is a lovely little book with 24 recipes plus a cooking times chart. I’ve used the chart more than any cookbook.
Cons
- Small food items like fries can slip between the grates. I’ve seen this in multiple reviews, and I’ve had it happen with my own shoestring fries. Spend the $11 for the magnetic strips that hold a paper liner in place, or use a perforated basket insert.
- The handle button took a bit of getting used to. It’s a button on the top of the handle, not a spring-loaded lever. You get used to it by day three.
- No dehydrator function. I’ve dehydrated chicken for my dog Biscuit in it anyway, using the lowest temperature and a longer time. It works, but it’s not a dedicated setting.
Compared to the Ninja DZ201 Foodi (B089TQWJKK)
The Ninja DZ201 is the other machine I’ve been living with this month. It’s a DualZone, so you can cook two different things at two different temperatures at the same time. That’s a genuine advantage for a family dinner: chicken thighs on one side, taters on the other, both done at the same time. The 8-quart advertised capacity is real, and the usable footprint is 6.4 quarts, which held six chicken thighs without crowding.
But the Ninja runs 10 degrees hot on average, and I caught it at 15 degrees hot during the preheat. I had to adjust my cook times and temperatures for everything. The basket is non-stick, not ceramic, and I’ve had frozen mozzarella sticks stick to the grates in a way the Cosori never does. And there’s no off button. It just waits to be fired up, blinking for a while after I’m done with it. I unplug it usually.
The Ninja is $149, which is $50 more than the Cosori at regular price. You’re paying for the DualZone feature and the larger capacity. If you cook for a family of four or more and need two zones, it’s worth the extra money. If you’re cooking for one or two, or you just want the best frozen food results, the Cosori wins. The temperature drift alone is a dealbreaker for me.
Test Results by Metric
Design. The Cosori TurboBlaze is a drawer-style air fryer, which I prefer. I’ve said it before and I’ll say it again: toaster-oven style air fryers burn everything, and their interior space is cramped. The drawer slides in and out smoothly, and the basket itself won’t go back in sometimes on the Chefman, but the Cosori has no alignment issues. The touchscreen is intuitive, and the preheat button is right there on the front. The ceramic coating is the difference between a machine you clean in seconds and one you dread touching. Melted cheese comes off with relative ease, easy peasy.
Performance. I cooked 40 foods in this machine over 30 days. The frozen fry test came out crispy in 12 minutes at 400°F. The chicken thigh crisp test passed with skin crackling and meat cooked through to 165°F. The cake test revealed no hot spots, which is rare. I’ve had machines where one side is burnt and the other is doughy, and the Cosori is not one of them. The preheat feature works, and it holds temperature within 5 degrees of the set point. That’s the difference between a machine you use daily and one you shove in the back of a cabinet.
Durability. I’ve had my Cosori for over a year, and the ceramic coating has held up beautifully. I’ve put it through the 30-day daily-use trial, and I’ve used it twice a day since. That’s over 700 meals. No flaking, no peeling, no exposed wires. My old air fryer had exposed wires, and I replaced it because it was a hazard, not because I wanted an upgrade. The Cosori feels solid, and the materials are quality. I’ve bought three more as gifts, one for my 87-year-old mom and one for my neighbor caring for her 101-year-old husband.
Value. I paid $85 on Prime Day. I’ve used it twice a day since. That’s pennies per meal, and it replaced a toaster oven that burned everything and a microwave that made leftovers soggy. The Ninja DZ201 is $149, and it’s a good machine, but the Cosori does the same job for less money with better temperature control. The Chefman 6 QT is a budget option at $60, but it has no preheat feature, no off button, and the basket alignment issues are real. You get what you pay for.
The Shake Rule
The Shake Rule is simple: almost everything needs to be flipped during cooking. Machines that remind you are worth their weight in gold. The Cosori has a shake prompt that beeps at the halfway mark, and the Chefman has one too. The Ninja has one as well. But the Cosori is the only one I trust to actually cook evenly after I shake it. The temperature drift on the Ninja means the second half of the cook is hotter than the first. The Cosori holds steady, so when I shake at 6 minutes, the remaining 6 minutes cook at the same temperature as the first 6.
I reheated pizza in it at 380°F for 4 minutes. Crispy crust, melty cheese, better than it was delivered. I made taquitos, it holds about 9. I cooked coconut shrimp from frozen in 8 minutes at 400°F, better than anything I’ve had at a restaurant. I reheated fried chicken, and it was better than when my HungryMan bought it fresh. I made hard-boiled eggs, easy peasy, just set the timer and walk away.
Should you buy it?
If you eat frozen food more than once a week, and you’re tired of soggy fries and unevenly cooked nuggets, yes. The Cosori TurboBlaze is the best air fryer for frozen food I’ve tested, because it preheats properly, holds temperature, and the ceramic coating makes cleanup a breeze. If you need two zones and a larger capacity, the Ninja DZ201 is worth the extra $50, but I’d rather have the Cosori and spend the difference on a good thermometer.
I’m currently testing the Chefman 6 QT against the Cosori for a budget comparison, and I’m working through a batch of the most popular air fryers on the market right now. I’ll update this when I have more data. God Bless the person who invented this thing. Voila!!
