Last night's chips don't need to stay limp, and pizza really shouldn't come back from the microwave with a soggy base. Reheating leftovers in an air fryer oven is one of those small kitchen wins that makes everyday meals quicker and much more satisfying. When you want hot food with a decent texture and less waiting around, an air fryer oven usually does a better job than a full-size oven and a far better one than the microwave.
In short: reheat most leftovers at 160°C to 180°C for 3 to 8 minutes, in a single layer, and check halfway through. Make sure the food is steaming hot all the way through before you eat it. The table below gives starting points for the foods people reheat most often.
Air fryer oven reheating times and temperatures
Use these as starting points. Times depend on portion size, how cold the food is and how full the tray is, so check early and add a minute or two if needed.
| Leftover | Temperature | Time | Tip |
|---|---|---|---|
| Pizza slices | 160°C to 180°C | 3 to 5 minutes | Thin crust needs less time than deep pan |
| Chips | 180°C | 3 to 6 minutes | Single layer, shake once |
| Roast potatoes | 180°C | 4 to 8 minutes | Turn halfway for even crisping |
| Breaded chicken, nuggets, spring rolls | 170°C to 180°C | 4 to 8 minutes | Larger pieces need the longer time |
| Sausage rolls and pastries | 160°C to 170°C | 3 to 5 minutes | Too hot and the outside browns first |
| Roasted vegetables | 170°C | 3 to 5 minutes | Firmer veg recovers best |
| Sliced cooked meat | 160°C | 3 to 5 minutes | Cover lean meat loosely with foil |
Whatever the food, the finish line is the same: piping hot all the way through. UK food safety guidance says reheated food should reach 75°C in the centre, so a food thermometer is useful for thicker portions.
Why air fryer ovens work so well for reheating leftovers
The appeal is simple. An air fryer oven circulates hot air quickly in a compact space, so food reheats faster and more evenly than it would in a full-size oven. Because the heat is dry rather than steamy, it helps restore crisp edges instead of softening everything on the plate.
That matters with the foods people actually reheat most often: pizza, roast potatoes, chicken goujons, spring rolls, chips, pastries and leftover veg. These are the meals that lose their appeal when they go rubbery or wet. The air fryer oven gives them a second chance without much effort.
It is not magic, though. Some foods will never taste exactly as they did fresh, and a few leftovers are better handled another way. Saucy pasta, stews and anything with a lot of liquid are usually better in the microwave or on the hob. The air fryer oven shines when texture matters.
How to reheat leftovers in an air fryer oven
A good result usually comes down to three things: temperature, spacing and timing. If the tray is crammed full, the hot air cannot circulate properly. If the heat is too high from the start, the outside can dry out before the middle is hot.
For most leftovers, a medium heat works best. Somewhere around 160°C to 180°C is the sweet spot. That is hot enough to warm food through and bring back crispness, but gentle enough to avoid burning the edges.
Preheating helps, especially for foods you want crisp, such as pizza or chips. It only takes a couple of minutes, but it gives the food a head start and can make the final texture more even. If you skip it, you can still get good results; just allow a little extra time.
One more thing people often skip is checking halfway through. Shake the basket, flip larger pieces and keep an eye on colour. Reheating is quicker than cooking from scratch, so the gap between perfect and overdone can be smaller than you think. If you are new to the controls, our guide on how to use an air fryer oven covers settings, temperatures and trays.
Reheating leftovers by food type
Pizza
Pizza is one of the clearest air fryer oven wins. Reheat slices at around 160°C to 180°C for 3 to 5 minutes. The base firms up, the cheese melts properly and the toppings warm through without turning greasy. Thin-crust pizza usually needs less time than deep pan, so start low and check early.
Chips and roast potatoes
Cold chips are a classic disappointment, but an air fryer oven revives them well. Spread them in a single layer and cook at about 180°C for 3 to 6 minutes, shaking once. Roast potatoes behave similarly and often come back with crisp edges that are surprisingly close to fresh.
Fried foods
Chicken strips, nuggets, tempura and similar leftovers all benefit from dry circulating heat. Reheat at around 170°C to 180°C for 4 to 8 minutes depending on size. The coating crisps up again, which is exactly what the microwave cannot do.
Pastries
Sausage rolls, croissants and savoury bakes can work beautifully, but they need a little care. Too hot, and the outside browns before the centre is warm. Aim for around 160°C to 170°C and check after 3 or 4 minutes.
Roasted vegetables
Roasted vegetables reheat well if they were not too soft to begin with. Use around 170°C for 3 to 5 minutes. They may not recover all their original texture, especially courgettes or aubergines, but they usually improve more than they would in the microwave.
Cooked meat
Slices of chicken breast, pork or beef can dry out if overheated, so lower temperatures are often better. Try 160°C in short bursts, checking regularly. If the meat is quite lean, a light covering of foil can help stop the edges going tough while the centre warms through.
Foods that need a different approach
There is a point where the air fryer oven stops being the smartest option. Leftover curry, chilli, soup, risotto and heavily sauced pasta generally reheat more evenly in a pan or microwave. An air fryer oven can dry the surface before the inside gets fully hot, and the basket is not designed for loose liquids unless you are using a suitable oven-safe dish.
Even then, it depends on the dish. A pasta bake with a firm top can work if it is in a proper container and reheated gently. Macaroni cheese can be decent too, especially if you add a small splash of water before heating so it does not tighten up too much. But for spoonable meals, the hob usually remains the safer bet.
Common mistakes that ruin reheated food
The most common mistake is overcrowding. It is tempting to put everything in at once, especially on a busy evening, but packed trays trap moisture. Instead of crisping, the food steams.
The second is setting the temperature too high. People often assume reheating should be as hot and fast as possible. In reality, leftovers are already cooked. You are warming them through, not trying to brown them from scratch.
Another issue is forgetting that different foods hold heat differently. A small portion of chips will reheat much faster than a thick slice of lasagne. If you are reheating a mixed meal, do not treat everything the same. Warm the sturdier items first and add more delicate bits later.
Do you need oil when reheating leftovers?
Usually, no. Most leftovers already contain enough surface fat to crisp up again on their own. Adding extra oil can help in a few cases, such as chips that have gone very dry, but use a light hand. A small spritz is plenty.
Too much oil can make food greasy rather than fresh-tasting. The point of reheating in an air fryer oven is to bring back texture without making a simple meal feel heavier than it needs to.
Food safety matters as much as flavour
Good texture is nice, but safe reheating matters more. Cool leftovers quickly, ideally within two hours, then cover them and keep them in the fridge. UK guidance is to eat most leftovers within two days and to reheat them only once.
- Reheat until the food is steaming hot all the way through, which means at least 75°C in the centre.
- Cut or break up thicker portions so the middle heats properly.
- Cooked rice needs extra care: refrigerate it promptly, eat it within 24 hours and do not reheat it more than once.
- If something has been left out too long, or you are not sure how old it is, throw it away.
An air fryer oven can improve yesterday's dinner, but it cannot rescue food that should have gone in the bin.
Why an air fryer oven earns its place for leftovers
This is where the air fryer oven earns its place on the worktop. It takes the effort out of those in-between meals when you are short on time but still want something enjoyable. Lunch at home feels less like making do, and midweek dinners become easier when leftovers actually taste worth eating.
For busy households, that convenience adds up. You waste less food, rely less on takeaways and spend less time waiting for a big oven to heat up. A larger model such as the f77 Super Oven Pro 30L air fryer oven gives you room to reheat more than one portion at once, while the compact f66 Super Oven 15L suits smaller kitchens and one or two people.
That is part of the reason appliances like these have become everyday essentials rather than occasional gadgets. Weighing one up against your main oven?

A quick rule of thumb
If the leftover was meant to be crisp, flaky, roasted or golden, the air fryer oven is probably your best option. If it was meant to be soft, saucy or spoonable, another method may suit it better.
That simple distinction takes most of the guesswork out of reheating. Start a little lower on temperature than you think, avoid overcrowding and check early. With that approach, reheating leftovers stops being trial and error and becomes one of the easiest ways to make everyday meals feel fresh again.
Frequently asked questions
What temperature should I reheat leftovers at in an air fryer oven?
For most leftovers, 160°C to 180°C works best. Use the lower end for pastries, sliced meat and thicker portions so the centre warms before the outside browns, and the higher end for chips, roast potatoes and breaded foods. Whatever you reheat, it should be steaming hot all the way through before you serve it.
How long does it take to reheat pizza in an air fryer oven?
Most pizza slices take 3 to 5 minutes at 160°C to 180°C. Thin crust is usually ready at the shorter end, while deep pan slices need a little longer. Lay the slices flat in a single layer, check after 3 minutes and stop once the base is crisp and the cheese has fully melted.
Can you reheat rice in an air fryer oven?
You can, but it is not the best tool for plain rice because it dries the surface quickly. If you do, use an oven-safe dish, add a splash of water and cover it. Rice should have been chilled promptly after cooking, eaten within 24 hours and reheated only once, until steaming hot throughout.
Do you need to preheat an air fryer oven to reheat food?
It is not essential, but a couple of minutes of preheating helps foods you want crisp, such as pizza, chips and breaded chicken. The hot air gets to work straight away, so the outside crisps while the centre warms. If you skip preheating, add a minute or two to the reheating time and check the middle.
