Why Use an Air Fryer for Reheating?
If you are still defaulting to the microwave, it is time to reconsider. The air fryer works by circulating intensely hot air around the food at high speed. This process, known as the Maillard reaction, is what creates the golden, crispy crust that makes food taste freshly cooked.
The microwave, on the other hand, heats food by exciting water molecules. This process inevitably makes the exterior of foods like pizza, chicken, and fries soggy and wet. The oven can achieve similar results to the air fryer, but it takes much longer and uses significantly more energy.
Mastering how to reheat food in an air fryer is the ultimate kitchen hack. It saves you time, reduces food waste, and makes your leftovers taste like a brand new meal. It is the single best tool for reviving texture and flavor.
General Rules for Reheating in an Air Fryer
Before we dive into specific foods, there are a few universal principles that will guarantee success every time you reheat food in an air fryer.
1. Always Preheat Your Air Fryer
This is the most important step. Do not skip it. Preheating ensures that the food hits the hot air immediately, starting the crisping process right away. Most air fryers take between 3 and 5 minutes to preheat. If your model doesn’t have a preheat button, just run it empty at the desired temperature for 3 minutes.
2. Do Not Overcrowd the Basket
Hot air needs to circulate around every piece of food. If you pile leftovers on top of each other, the food will steam instead of crisping up. You will end up with uneven results. Always place food in a single layer, leaving a little space between each piece.
3. Use the Right Temperature
Generally, you will want to reheat food at a slightly lower temperature than you cooked it at. High heat can burn the outside before the inside is warm. A good starting point is between 300°F (150°C) and 375°F (190°C). We will cover specific temperatures for different foods below.
4. Shake or Flip Halfway Through
Air fryers have hot spots. To ensure even heating, pause the machine halfway through the reheating time and shake the basket (for fries and small items) or flip the food (for chicken, steak, and pizza).
5. Add a Little Oil (Optional)
If your leftovers look a bit dry, spritzing them with a light coating of oil (avocado or olive oil spray works best) can help restore moisture and promote crisping. Be careful not to use too much, or the food will become greasy.
How to Reheat Pizza in an Air Fryer
This is the reason many people buy an air fryer in the first place. The air fryer does the impossible: it makes leftover pizza taste better than it did the night before. The crust becomes perfectly crunchy, the cheese melts beautifully, and the toppings are hot and bubbly.
Step-by-Step Instructions
- Preheat your air fryer to 350°F (175°C).
- Place the pizza slices directly into the basket. Do not stack them. If you have a larger air fryer, you can fit multiple slices in a single layer. If you have a smaller basket, reheat them one at a time.
- Heat for 3 to 5 minutes. For thin crust pizza, check at the 3-minute mark. For thick crust or deep-dish, it may take up to 6 minutes.
- Remove and let it cool for one minute before eating. The crust will be shatteringly crisp, and the cheese will be perfectly melted.
Pro Tip: If you are reheating a slice with a lot of oily toppings (like pepperoni), place a piece of parchment paper under the pizza to catch the drips. This makes cleanup much easier.
How to Reheat Fried Chicken and Other Fried Foods
Fried chicken is notoriously difficult to reheat. The microwave turns the skin into a sad, soggy mess. The oven works, but it takes a long time. The air fryer restores the crispy, crunchy skin in minutes.
Step-by-Step Instructions
- Preheat your air fryer to 375°F (190°C).
- Place the chicken pieces in the basket. Make sure they are not touching. If you have a lot of chicken, reheat it in batches.
- Heat for 6 to 10 minutes. Boneless tenders will be ready in about 6 minutes. Bone-in thighs and legs will take closer to 10 minutes. Flip the chicken halfway through.
- If the skin looks dry, spritz it lightly with cooking oil before reheating.
Pro Tip: This method works perfectly for other fried foods like onion rings, mozzarella sticks, and egg rolls. The key is to keep the temperature moderate and the time short so the filling gets hot without the coating burning.
How to Reheat Steak and Meat
Reheating a steak is a delicate operation. The goal is to warm the center without turning the exterior into a well-done, leathery crust. The air fryer can do this, but you need to go low and slow.
Step-by-Step Instructions
- Preheat your air fryer to 300°F (150°C).
- Take the steak out of the fridge and let it sit at room temperature for about 10 minutes.
- Place the steak in the basket. Heat for 5 to 8 minutes, flipping halfway through.
- Check the internal temperature with a meat thermometer. You are aiming for the same doneness you originally cooked it to (e.g., 130°F for medium-rare).
- Let the steak rest for 2 minutes before cutting. This allows the juices to redistribute.
Pro Tip: If you have a thick steak, you can reduce the temperature to 250°F (120°C) and increase the time slightly. This gives the heat more time to penetrate the center without burning the outside.
How to Reheat French Fries and Potato Wedges
Cold, limp French fries are a tragedy. The air fryer is the only device that can actually bring them back to life. They won’t be exactly like fresh, but they will be close enough to make you happy.
Step-by-Step Instructions
- Preheat your air fryer to 400°F (200°C).
- Spread the fries out in the basket. Do not overcrowd them.
- Spray them lightly with cooking oil and toss them to coat.
- Heat for 3 to 6 minutes. Shake the basket halfway through. For extra crispy fries, add one minute to the time.
Pro Tip: This method works for all types of potato products: tater tots, hash browns, curly fries, and potato wedges. The high heat is what restores the crunch.
How to Reheat Pasta and Casseroles
Pasta can be tricky because it dries out easily. However, for baked pasta dishes like lasagna, ziti, or mac and cheese, the air fryer is excellent. For plain spaghetti with sauce, you need to take precautions.
For Baked Pasta (Lasagna, Ziti)
- Preheat your air fryer to 350°F (175°C).
- Place the portion in an oven-safe dish that fits inside your basket.
- Heat for 8 to 12 minutes. The top will become bubbly and slightly crispy, while the inside stays creamy.
For Saucy Pasta (Spaghetti, Alfredo)
- Preheat your air fryer to 300°F (150°C).
- Place the pasta in an oven-safe dish. Add a tablespoon of water or a splash of milk to create steam.
- Cover the dish securely with aluminum foil.
- Heat for 5 to 8 minutes, stirring halfway through.
How to Reheat Vegetables and Roasted Veggies
Roasted vegetables often become mushy when reheated in the microwave. The air fryer helps them retain their texture and even adds a bit of extra char. This works best for hearty vegetables like broccoli, cauliflower, carrots, and Brussels sprouts.
Step-by-Step Instructions
- Preheat your air fryer to 350°F (175°C).
- Spread the vegetables in a single layer in the basket.
- Heat for 3 to 5 minutes. Shake the basket halfway through.
- Check frequently. Vegetables can go from perfectly roasted to burnt very quickly.
Pro Tip: If your vegetables are looking a little shriveled, spritz them with a little oil and water before reheating. This will help plump them back up.
How to Reheat Bread, Rolls, and Croissants
There is nothing quite like a warm, flaky croissant or a soft, warm dinner roll. The air fryer can revive bread products in just a few minutes. Be careful, though, because bread burns easily due to the high sugar content.
Step-by-Step Instructions
- Preheat your air fryer to 300°F (150°C).
- Place the bread item in the basket. If it is a roll or croissant, you can slice it in half to ensure the inside gets warm.
- Heat for 2 to 4 minutes. Check at the 2-minute mark. The bread should be warm and slightly crispy on the outside.
- For garlic bread or cheesy bread, you can add one extra minute to melt the cheese.
Pro Tip: To make stale bread taste fresh again, lightly mist it with water before reheating. The moisture will steam the inside while the air crisps the crust.
How to Reheat Leftovers from Chinese Takeout
Chinese takeout leftovers are a staple in many households. The air fryer is perfect for reviving the crispy elements of these dishes, like spring rolls, egg rolls, and fried wontons. It also does a great job with fried rice.
Step-by-Step Instructions
- Preheat your air fryer to 375°F (190°C).
- For fried rice: Spread it in a thin layer on a piece of parchment paper or directly in the basket. Heat for 4 to 6 minutes, stirring halfway through.
- For spring rolls, egg rolls, and wontons: Place them in the basket in a single layer. Heat for 4 to 7 minutes, flipping halfway through.
- For saucy dishes like orange chicken or General Tso’s, it is better to use the microwave or a stovetop pan, as the sauce will burn in the air fryer. You can, however, air fry the chicken pieces first to crisp them, then toss them in the sauce.
How to Reheat Breakfast Items
Breakfast leftovers are a joy, and the air fryer makes them even better. Whether you have leftover pancakes, bacon, or scrambled eggs, the air fryer can handle it.
Pancakes and Waffles
- Preheat to 350°F (175°C).
- Stack the pancakes or waffles in the basket. They can be touching.
- Heat for 2 to 3 minutes. The edges will become crisp, and the inside will be fluffy.
Bacon
- Preheat to 350°F (175°C).
- Place the bacon strips in the basket. They can overlap slightly, but try to keep them in a single layer.
- Heat for 3 to 5 minutes. It will come out perfectly crispy.
Scrambled Eggs
- Preheat to 300°F (150°C).
- Place the eggs in a small oven-safe dish.
- Heat for 2 to 3 minutes. Stir halfway through. Be careful not to overcook them, as they will become rubbery.

Tips and Best Practices for Air Fryer Reheating
To truly master how to reheat food in an air fryer, keep these additional tips in mind. They will help you avoid common mistakes and get the best results every time.
- Use a Meat Thermometer: When reheating meat, chicken, or fish, don’t rely on guesswork. Use a digital meat thermometer to ensure the center has reached a safe temperature of 165°F (74°C) for poultry and 140°F (60°C) for beef.
- Adjust for Your Specific Model: Air fryer models vary widely in power and heat distribution. A 6-quart basket may cook faster than a 10-quart oven-style model. Start with the lower end of the suggested time range and add more time if needed.
- Use Parchment Paper or Foil Wisely: You can line your basket with parchment paper to catch drips and make cleanup easier. However, do not use paper without food on top to weigh it down, as it could blow around and touch the heating element. Always poke holes in the paper to allow air circulation.
- Don’t Overcrowd: This cannot be stressed enough. If you fill the basket to the brim, the food will steam. For the crispiest results, the basket should be no more than half full.
- Clean Your Air Fryer Regularly: A dirty air fryer can impart old, burnt flavors to your fresh leftovers. Clean the basket and drawer after every use with warm, soapy water or a non-abrasive sponge.
- Thaw Before Reheating (If Possible): If you are reheating food that was frozen, it is best to thaw it in the refrigerator overnight. This ensures even reheating. If you are in a rush, you can reheat from frozen, but add 3 to 5 minutes to the recommended time and check often.
Frequently Asked Questions
Can I put aluminum foil in the air fryer?
Yes, you can use aluminum foil in the air fryer. However, you must use it carefully. Make sure the foil is weighed down by food so it doesn’t blow around and touch the heating element. Also, avoid covering the entire basket, as this will restrict air circulation. Only use foil to line the bottom or to cover a dish.
Can I reheat food in a paper bag or cardboard box?
No. Unlike a microwave, an air fryer gets extremely hot and uses powerful fans. Paper bags and cardboard boxes are a fire hazard. They can easily ignite or shed particles into the food. Always remove leftovers from their takeout containers and place them directly in the basket or on a heat-safe plate.
Why is my food burning on the outside but cold in the middle?
This is a classic sign that the temperature is too high and the time is too short. The intense heat is cooking the outside before the inside has a chance to warm up. Lower the temperature by 25°F (or 15°C) and increase the cooking time. This allows the heat to penetrate the center more gently.
Do I really need to preheat the air fryer to reheat food?
Yes, preheating is highly recommended when you want to learn how to reheat food in an air fryer properly. Starting with a hot basket ensures that the food begins to crisp immediately. If you put food into a cold air fryer, it will take longer to heat up, and the texture will suffer. The only exception is if you are reheating something very delicate that might burn, like a croissant.
Can I reheat multiple different foods at the same time?
Yes, you can reheat different foods together, but only if they require a similar temperature and time. For example, you can reheat French fries and chicken tenders together because they both work well at 375°F for about 6 minutes. Avoid mixing foods with drastically different reheating requirements, like a wet casserole and crispy fries.
Is it safe to reheat food in an air fryer?
Yes, it is perfectly safe. The air fryer cooks food using hot air, which is a dry heat method. As long as you ensure that the food reaches a safe internal temperature (165°F for leftovers), it is just as safe as using an oven or stovetop. Always make sure your food is stored properly in the fridge before reheating.
Conclusion
Reheating food doesn’t have to be a disappointing experience. By learning how to reheat food in an air fryer, you can transform your leftovers into meals that taste almost as good as the original—sometimes even better. The air fryer gives you back the texture, the crunch, and the flavor that the microwave steals away.
Whether you are reviving a slice of pizza, a piece of fried chicken, or a batch of soggy French fries, the air fryer is the tool you need. Start with the general rules, follow the specific guides for your favorite foods, and don’t be afraid to experiment a little. Once you see the results, you will never go back to the microwave again. Your leftovers deserve better.
