How To Reheat Food In An Air Fryer
I’ve said it before and I’ll say it again: the air fryer beats the microwave for reheating, period. Reheated fried chicken is better than when my HungryMan brought it home fresh. Pizza comes out with a crispy crust and melty cheese instead of a soggy mess. It’s the reason I’ve barely touched my conventional oven since I got my Cosori TurboBlaze for ~$85 on Prime Day.
The air fryer is the best leftover-reheating appliance I own, because it restores texture instead of nuking it into submission. But the how matters more than the what. You can’t just toss last night’s takeout in the basket and hope. I’ve burned enough edges and dried out enough chicken thighs to know the rules. Here’s what actually works.
Pros:
- Crispy exteriors come back. Pizza crust, fried chicken skin, tater skins all get their crunch restored.
- Even heating beats the microwave’s soggy center-cold edges problem.
- Fast. Most things take 3 to 8 minutes. Reheating a full plate takes less time than preheating the oven.
Cons:
- Small items can slip through the grates. Fries and loose rice will fall into the bottom and burn.
- Almost everything needs to be flipped halfway through. Set a timer, don’t walk away.
- You have to learn your machine’s hot spots. I’ve cut into plenty of “gorgeous” reheated chicken thighs to find a cold center.
Compared to the Microwave and the Oven
The microwave makes leftovers sad. It turns crispy things soggy and hot things cold in the middle. The conventional oven takes 15 minutes to preheat and heats up the whole kitchen. The air fryer sits between them: faster than the oven, better texture than the microwave.
I’ve tested this against the Ninja DZ201 Foodi 8 Quart 6-in-1 DualZone in my shop. The Ninja’s DualZone feature is genuinely useful for reheating two things at once, like pizza and fries, at different temperatures.
But the Cosori TurboBlaze is quieter about it. I sometimes have to check if the Cosori is even on. The Ninja is noticeably louder during operation.
For a machine I use daily for reheating, quiet wins.
Reheating Pizza
Set it to 380°F. No preheat needed if your machine has a good preheat feature, but the Cosori’s preheat actually works, so I use it. Three minutes, check it, maybe another minute. The crust comes out crackly, the cheese melts back to gooey, and it tastes like it came from the pizzeria, not the fridge.
The Chefman 6 QT has no preheat feature. I’ve tested that machine too, and you just have to wait for the temperature to reach the desired level. It works, but it adds a couple minutes to every reheating session. On a Tuesday night when I’m tired, those minutes matter.
Reheating Fried Chicken
This is the test that converted me. My HungryMan brought home fried chicken, we ate half, and the rest sat in the fridge overnight. The microwave made it rubbery. The air fryer at 400°F for 4 minutes, flip, another 3 minutes, brought back the crackling skin. Better than when he bought it fresh. It takes me back to Sunday dinners at my mom’s house.
The trick is the flip. Almost everything needs to be flipped during cooking. If you skip it, the bottom stays soggy while the top gets dark. The Cosori’s basket is easy to shake. The Chefman’s basket just won’t go back in sometimes, like it doesn’t slide in well and takes a minute to get perfectly lined up. That’s the budget tradeoff.
Reheating Taters
Gorgeous taters are the whole reason I bought an air fryer. Reheating them is easy peasy. Cut them into wedges, spritz with oil, 400°F for 5 minutes, shake at the halfway mark. They come out crispy on the outside, fluffy on the inside.
Small fries are the problem. They slip between the grates and burn at the bottom. I’ve seen this in multiple reviews, and I’ve lived it. The fix is a paper liner, but you have to spend the ~$11 for the magnetic strips that hold it in place.
Otherwise it slides around. And do not put a paper liner in the basket during PreHeat. That’s a fire risk.
I’ve seen people blame the machine for a fire that was really a liner error.
Reheating Steak
This is a niche move, but it works. Slice the steak thin, 350°F for 2 minutes, flip, another minute. It warms through without turning gray. The outside gets a little crust back. My 87-year-old mom does this with her Cosori and she made salmon cakes on day one. If she can do it, anyone can.
The cake test is my favorite way to find hot spots. I baked a cake in the Chefman and it came out golden brown on one edge and doughy on the other. The Cosori held temperature within 5 degrees of the set point.
That even heat is why my reheated food comes out consistent. The Chefman ran 15 degrees hot on preheat, which means I have to account for the drift manually.
For a budget machine, you get what you pay for.
Reheating Casseroles
Use a lower temperature, 325°F, and cover with foil for the first half. This keeps the top from burning before the middle warms through. Casseroles are dense, so they take longer. Plan for 8 to 10 minutes, flipping or stirring at the halfway mark.
The Ninja DZ201 handles this well because you can set one zone to 325°F and the other to 400°F for whatever else you’re reheating. I’ve done a casserole in one zone and biscuits in the other. The handle button took a bit of getting used to, but the DualZone feature is the reason to buy the Ninja over the Cosori if you cook for a crowd.
Reheating Hard-Boiled Eggs
This sounds weird, but it works for deviled eggs. 300°F for 3 minutes warms the filling without turning the whites rubbery. I tested this after a neighbor asked about it. She’s caring for her 101-year-old husband and uses her air fryer for almost everything. These machines aren’t just gadgets. They’re tools that let people keep cooking for the people they love.
Should You Buy an Air Fryer for Reheating?
If you reheat leftovers more than twice a week, yes. The Cosori TurboBlaze at ~$85 is the best value I’ve found. It’s quiet, the ceramic coating releases even melted cheese with ease, and the basket is dishwasher-safe. I’ve bought three as gifts: one for me, one for my mom, one for my neighbor. The neighbor’s husband is 101 and he uses it himself. That’s a small miracle.
If you’re on a tight budget, the Chefman 6 QT works, but you’ll deal with the basket alignment and the blinking light when it’s off. I unplug it usually, ’cause it’ll blink for a while. No off button is a real annoyance. But it’s a good deal for the price.
If you cook for more than two people, the Ninja DZ201’s DualZone is worth the extra money. Two baskets, two temperatures, one appliance. It’s louder than the Cosori, but the capacity makes up for it.
What I’m Testing Next
I’m working through a batch of the most popular air fryers on the market right now. I’ve got a toaster-oven style model in my shop that burns everything and has a cramped interior. Drawer style is superior. I’ve said it before and I’ll say it again. Next up is a budget unit that claims 6 quarts but measures closer to 4.5. I’ll update this guide when I have the data. for the Cosori TurboBlaze or for the Ninja DZ201. Spend the ~$11 on magnetic strips for your paper liners. Let your food-freak flag fly. God Bless!
