Can you reheat food in an air fryer? Yes, you can reheat food in an air fryer, provided that the food was cooked and stored safely and is suitable for dry circulating heat.
An air fryer can be especially effective for pizza, chips, roast potatoes, fried chicken, pastries and breaded food. It reheats the surface more effectively than a microwave, helping food become crisp rather than soft or rubbery.
However, an air fryer is only one answer to can you reheat food in an air fryer oven and can you reheat food in an air fryer like a microwave? Depending on the meal and the equipment available, a hob, skillet, oven, toaster oven, steamer or carefully controlled hot-water bath may be more suitable.
Whatever method you use, the essential food-safety rules remain the same:
- refrigerate leftovers within two hours of cooking;
- use refrigerated leftovers within 48 hours or freeze them;
- reheat each portion only once;
- make the food steaming hot throughout;
- aim for approximately 75°C in the centre when using a thermometer.
Times and appliance settings are useful starting points, but they do not prove that food is safe. A thick chicken portion may remain cool inside even when its surface is crisp and browned.
Can You Reheat Food in an Air Fryer?
An air fryer works by circulating hot air rapidly around food. This makes it particularly useful for reheating foods that originally had a crisp, baked, roasted or fried texture.
Suitable foods include:
- pizza;
- chips;
- roast potatoes;
- fried or breaded chicken;
- chicken wings;
- pastries;
- spring rolls;
- roasted vegetables;
- bread rolls;
- small pies.
Many modern air fryers have a dedicated reheat setting. Where one is available, follow the manufacturer’s recommended temperature and time. Otherwise, approximately 160°C to 180°C is a practical starting range for many cooked leftovers.
Arrange food in one layer where possible. Leaving space between pieces allows hot air to circulate and promotes more even reheating. Overloading the basket can leave food cold where pieces touch.
Turn individual pieces or shake the basket halfway through. Before serving, check the centre of thick, filled or bone-in foods.
Air fryers are less suitable for loose soups, thin sauces and very wet dishes unless the manufacturer permits the use of a suitable heat-resistant container.
Suggested Air-Fryer Reheating Times
The following times are estimates for refrigerated food, not guaranteed safety times:
| Food | Starting air-fryer setting | Approximate time | Important check |
| Pizza slices | 160°C–180°C | 3–5 minutes | Centre and toppings steaming hot |
| Chips | 180°C | 3–6 minutes | Shake halfway |
| Roast potatoes | 180°C | 5–8 minutes | Cut one open and check centre |
| Fried chicken pieces | 170°C–180°C | 5–10 minutes | Thickest part steaming hot |
| Chicken wings | 180°C | 5–8 minutes | Check near the bone |
| Spring rolls | 170°C–180°C | 4–7 minutes | Filling thoroughly hot |
| Pastries | 160°C–170°C | 4–8 minutes | Filling hot without burning pastry |
| Roasted vegetables | 170°C | 4–7 minutes | Stir or turn halfway |
| Small pie | 160°C–170°C | 8–15 minutes | Filling reaches safe temperature |
Larger portions require longer. Frozen food may require a different setting and should be reheated from frozen only when the manufacturer’s instructions or a reliable recipe permits it.
The appliance may brown food before the centre is ready. Use a clean thermometer for meat, filled pastries and thick dishes where possible.
Food-Safety Rules Before Reheating
Learning can you reheat food in an air fryer ninja begins with checking whether the leftovers are still safe to use.
Food should normally have been cooled and refrigerated within two hours of its original cooking. Refrigerated leftovers should generally be eaten within 48 hours or frozen.
Do not reheat food that:
- was left at room temperature overnight;
- has been stored beyond its safe period;
- has already been reheated once;
- has an uncertain storage history;
- is past its use-by date;
- carries instructions saying it must not be reheated.
Reheating cannot reliably reverse every effect of unsafe storage. Some microorganisms can produce toxins while food is held incorrectly, and how to reheat food without a microwave those toxins may remain even after the food becomes hot.
Remove only the quantity you intend to eat. Leave the remaining portion cold in the fridge rather than reheating a complete container and cooling it again.
Proper Reheating Temperature
Household leftovers should become steaming hot throughout, not just warm.
A clean food thermometer should read approximately 75°C at the centre or coldest point. Large or irregular foods should be checked in more than one place.
The appliance temperature is different from the food temperature. Setting an air fryer or oven to 180°C does not mean the centre of the meal has reached 75°C.
Check:
- the centre of casseroles and lasagne;
- the thickest part of meat;
- areas close to bones;
- the filling of pies and pastries;
- several parts of a mixed dish.
Eat the food promptly after reheating. Do not leave it sitting warm for an extended period.
Practical Ways to Reheat Without a Microwave
1. The Steaming Method
The basic steaming method involves placing food in a heat-resistant dish above simmering water and covering the pan so that steam surrounds it.
This is useful for:
- rice;
- dumplings;
- cooked vegetables;
- fish;
- soft buns;
- sliced chicken;
- moist grain dishes.
Place a small amount of water in a deep pan and position a heat-resistant plate or shallow bowl above the water. how to reheat food without a microwave The dish should not sit directly in the water unless it is designed to do so.
Cover the pan and allow the steam to heat the food. Stir or turn the food where practical.
Approximate reheating time is usually 5–15 minutes, depending on the quantity and density. Check that the centre is steaming hot.
This method retains moisture well but will soften food that was originally crisp.
2. Stovetop Reheating
A saucepan on the hob is often the can you warm up food in an air fryer when the meal contains liquid.
It works well for:
- soup;
- stew;
- curry;
- sauce;
- pasta;
- chilli;
- risotto;
- cooked rice dishes.
Place the food in a saucepan and add a small amount of water, milk, stock or sauce if it appears dry.
Use low-to-medium heat and stir frequently. Scrape the bottom of the pan so that food does not burn while the centre remains cool.
Covering the pan can help retain steam, but the food still needs to be stirred. Continue until the entire portion is bubbling or steaming hot.
Approximate times range from 3–10 minutes for small portions and longer for dense dishes.
3. Reheating in a Skillet
A frying pan or skillet is useful when food should remain relatively dry or develop a crisp surface.
Suitable foods include:
- stir-fries;
- noodles;
- fried rice;
- sliced meat;
- cooked vegetables;
- pizza;
- flatbreads;
- quesadillas.
Add a small amount of oil or water according to the dish. Spread the food into an even layer and use moderate heat.
Turn or stir it regularly. For thick meat or filled foods, reduce the heat and cover the pan for part of the time so that the centre warms before the outside burns.
how to reheat food without a microwave Most small portions take approximately 4–10 minutes.
A skillet is a useful answer to can you heat up food in an air fryer when you want better texture than boiling or steaming would provide.
4. Oven or Toaster Oven

An oven is suitable for larger meals and foods that should remain baked or crisp.
Use it for:
- lasagne;
- casseroles;
- roast meat;
- pies;
- baked pasta;
- pizza;
- roast vegetables;
- breaded food.
Preheat the oven to approximately 160°C–180°C, unless the original instructions specify otherwise.
Place the food in an oven-safe dish. Cover moist dishes with foil to stop the surface drying before the centre becomes hot. Remove the foil during the final few minutes when browning is desired.
A full-sized oven may take approximately 10–30 minutes, depending on portion depth. how to reheat food without a microwave A toaster oven often reheats a small portion more quickly.
People asking can you reheat meat in an air fryer can therefore use an oven, toaster oven or air fryer. The correct choice depends on the food and available appliance.
5. Air Fryer
The air fryer is one of the strongest options for crisp leftovers.
Preheat it if the appliance instructions recommend doing so. Begin at around 160°C–180°C and place food in a single layer.
Shake the basket or turn the food halfway through. Add only a light amount of oil if the texture requires it; many leftovers already contain enough fat.
Avoid placing loose baking paper in an empty air fryer, as circulating air may lift it towards the heating element. Use accessories approved for the specific model.
When asking can you reheat meals in an air fryer, remember that the answer is yes only for foods and containers suitable for the appliance. Thin plastic, polystyrene and ordinary takeaway boxes must not be placed inside.
6. Steamer Basket
A dedicated steamer basket provides more controlled steam circulation than placing a plate inside a pan.
Bring a small amount of water to a gentle simmer. Put the food in the basket without packing it too tightly, then cover it with a fitted lid.
A steamer basket works especially well for:
- dumplings;
- bao buns;
- vegetables;
- rice portions;
- fish;
- sliced poultry.
Reheating normally takes approximately 5–12 minutes. Turn or rearrange larger portions and check the centre.
The distinction between this and the basic steaming method is the equipment: the first can be improvised using a heat-resistant dish, while this method uses a purpose-built perforated basket.
7. Hot-Water Bath
A hot-water bath can reheat certain sealed foods gently when no conventional cooking appliance is available.
It should be used only when the food is in:
- a commercially sealed boil-in-the-bag package;
- a heat-resistant sous-vide pouch;
- a sealed container expressly designed for hot-water heating.
Bring water to a simmer, place the sealed package in the water and follow the manufacturer’s instructions.
Do not place ordinary takeaway containers, cling film, thin food bags or unknown plastics into hot water. how to reheat food without a microwave They may leak, soften or be unsuitable for heating.
The food should not merely become warm. Once removed from the package, check that it is steaming hot throughout.
Depending on the product and portion size, this method may take approximately 10–20 minutes. It is not suitable for food that cannot be kept completely sealed.
Microwave-Free Heating: Food Type, Alternative and Tips

- an approved hot-water bath using an electric kettle and heat-safe container.
Where only a kettle is available, do not pour hot water directly into ordinary food containers or assume that soaking a meal until lukewarm is sufficient. how to reheat food without a microwave The food must reach a safe temperature throughout.
How to Reheat Food Without a Microwave at Work
Workplace options depend on the facilities and safety rules.
Possible methods include:
- a shared toaster oven;
- an approved air fryer;
- an electric food warmer designed to reheat food;
- a multicooker where workplace rules permit it;
- a hot-water bath for an approved sealed product.
A food flask is another practical solution, although it should be filled with properly reheated steaming-hot food at home rather than used to reheat a cold meal. Preheat the flask with boiling water, empty it and add the hot food immediately.
Anyone researching can you reheat food in an air fryer oven should check the employer’s appliance and fire-safety policies before bringing electrical equipment.
How to Warm Food Without a Microwave or Oven
When neither a microwave nor oven is available, use the hob, skillet, steamer basket or a suitable multicooker.
For can you reheat food in an air fryer oven, the stove is usually best for liquid or moist meals. Steam works well for rice, dumplings and vegetables, while a skillet suits noodles, pizza and sliced meat.
The aim should be thorough reheating rather than gentle warming. how to reheat food without a microwave Food that is only lukewarm may remain within the bacterial danger zone.
How to Warm Food Without a Microwave or Stove

For can you reheat food in an air fryer oven, use an air fryer, oven, toaster oven, electric steamer or approved hot-water method.
Do not improvise with unsafe appliances. Radiators, room heaters, coffee-machine hotplates and direct contact with kettles are not appropriate methods for thoroughly reheating ordinary leftovers.
Common Mistakes to Avoid
Overcrowding an air fryer
Closely packed pieces block circulating air and may remain cold where they touch.
Using one fixed time for every food
Three minutes may be enough for a pizza slice but inadequate for a thick chicken portion.
Judging only by crispness
A browned surface can hide a cool centre.
Reheating the entire batch
Take one cold portion and leave the remainder refrigerated.
Using unsuitable containers
Plastic, cardboard and polystyrene should not enter an oven or air fryer unless specifically approved.
Slowly warming food
The purpose is to reheat it rapidly until steaming hot, not keep it lukewarm for an extended period.
Reheating more than once
UK household guidance advises one reheating cycle only.
