How to Reheat Chips in the Air Fryer (Chippy Chips Too)
To reheat chips in the air fryer, spread them in a single layer and cook at 160°C to 200°C for roughly 4 to 10 minutes, shaking the basket halfway. A small portion of chippy chips you just want hot is done in about 4 to 5 minutes. A full basket you want properly crisp again needs nearer 10 minutes at 200°C. Check one of the thickest chips before you serve: it should be steaming hot in the middle, not just warm on the outside.
That’s the method. The rest is how to stop them going leathery, and how to keep leftover chips safe until you get to them.
First, a confession about leftover chips
On my frozen chips in the air fryer page I say chips reheat badly, and I stand by it for the microwave. A microwave steams them, and a steamed chip is a sad, bendy thing. Cooking only what you’ll eat is still the cheapest plan.
But real life includes a Friday chippy tea where the kids order big and eat half. Two portions of chips are not going in the bin on a one-income budget. The air fryer is the rescue. It blows dry heat round each chip, so the outside crisps up again instead of going soft.
The times, from two UK recipes
Two UK air fryer sites give different numbers, which tells you something useful: there’s a range, and your machine decides where you land in it.
- Feast Glorious Feast, in its chippy chips in the air fryer recipe, cooks leftover chip shop chips for 10 minutes at 200°C in a preheated air fryer, with a shake after 5 minutes. It adds that if you “just want them hot and aren’t bothered about them being mega crisp”, they are likely to be piping hot after around 5 minutes.
- Recipe This, in its reheat fish and chips in the air fryer guide, puts leftover chips in for 4 minutes at 160°C. For fish and chips together it uses 6 minutes at 160°C, then 2 more at 180°C to crisp them up.
So here is a sensible starting point:
| What you’re reheating | Temperature | Rough time |
|---|---|---|
| One portion, just want it hot | 160°C | 4-5 minutes |
| A full basket, want it crisp | 200°C | 8-10 minutes |
| Chips and battered fish together | 160°C, then 180°C | 6 minutes, then 2 more |
| Chips you froze, straight from frozen | 200°C | about 12 minutes |
The frozen figure is Feast Glorious Feast’s: it cooks frozen leftover chippy chips for 12 minutes at 200°C. Always check at the lower end. Thin chip shop chips can go from golden to crunchy brown sticks in a minute or two.
How to do it so they actually crisp
- Take them out of the paper or the tub. Chips that have sat wrapped have soaked up their own steam. Tip them out and let them sit for a few minutes while the air fryer warms up.
- One layer, loosely. This matters more than the time. Piled chips steam each other and you get the microwave texture you were trying to avoid. If you have a lot, do two batches. The first lot stays hot on a warm plate while the second cooks.
- No extra oil. Chip shop chips are fried, and frozen oven chips come coated. They already have plenty of fat on them.
- Shake at halfway. The chips cook where the hot air hits. A shake turns them over and moves the pale ones to the top.
- Salt and vinegar at the end. Add them after reheating, not before. Vinegar on a cold chip just makes it soggy before it starts.
Keeping leftover chips safe
Chips are cooked potato, so the same rules apply as for any leftovers. The government’s cooking your food guidance, which I read again on 11 October 2026, says:
- leftovers should be cooled and put in the fridge within two hours
- you should eat leftovers within 48 hours or freeze them
- when reheating leftovers, you should only ever reheat once
- food should be cooked to steaming hot throughout, rather than warmed, because the high temperature kills bacteria
So chips left on the side overnight go in the bin, sadly. Chips cooled and in a covered tub in the fridge within two hours are fine for tomorrow’s tea. Reheat only the amount you’re going to eat, because once is your one go.
Freezing works too. Spread cooled chips on a tray so they freeze separately, then bag them. That’s how you get the “straight from frozen” line in the table.
Turning leftover chips into a second tea
A handful of reheated chips is a side, not a meal. Here’s what turns them into tea:
- Chips and fish fingers. Put the fish fingers in the air fryer first and add the chips for the last few minutes, so it all finishes together.
- Cheesy chips. Scatter grated cheese over for the last minute or two. It’s the cheapest upgrade in the kitchen.
- Chip butty. Hot chips, buttered bread, a bit of ketchup. Every fussy eater I’ve ever met says yes to this.
- Loaded chips. Spoon over any leftover chilli or bolognese, with cheese on top.
If you’d rather start from scratch next time, my air fryer chips post covers fresh potatoes cut, soaked and crisped. It takes more effort, but it costs very little for a big bowl.
Where it usually goes wrong
- Too many in the basket. Overcrowding is behind nearly every soggy reheat.
- Too long at 200°C. Thin chips dry out fast. Check early.
- Reheating twice. Food safety rules say once only, and they’d taste like crisps by then anyway.
- Microwaving first “to speed it up”. All that does is steam them and undo the air fryer’s work.
FAQ
How long do you reheat chips in an air fryer?
Usually 4 to 10 minutes. About 4 minutes at 160°C if you only want a small portion hot, or up to 10 minutes at 200°C, shaken halfway, for a full basket you want crisp. Check one of the thickest chips before you serve.
Can you reheat chippy chips the next day?
Yes, if they were cooled and in the fridge within two hours of buying them. Gov.uk says eat leftovers within 48 hours and reheat them only once, until they’re steaming hot all the way through.
Do you need to add oil when reheating chips?
No. Chip shop chips are fried and frozen chips come coated, so they already have oil on them. Extra oil makes them greasy, not crisper.
Can you reheat chips from frozen in the air fryer?
Yes. Freeze cooled chips spread out on a tray, then cook them from frozen. Feast Glorious Feast gives 12 minutes at 200°C for frozen leftover chippy chips. Don’t defrost them first, or they go soggy.
Why are my reheated chips still soggy?
They were probably piled up, or still in the wrapper steaming before they went in. Spread them in one layer, cook in two batches if you need to, and give them a few extra minutes at 200°C.
