How to Reheat Food in an Air Fryer — Times, Temperatures, and What to Avoid

Reheat most leftovers in the air fryer at 160–175°C (325–350°F) for 3–10 minutes—not at the same temperature you used to cook the food the first time. The goal is to heat through until steaming hot and restore texture, not to brown the outside again while the center stays cold.

Why Reheating Is Not the Same as Cooking

When you cook raw food, you use high heat to drive moisture out of the surface and build crust. Leftovers already have a dry, set exterior. Hit that same temperature again and the outside burns or turns leathery before the inside reaches a safe eating temperature.

Air fryers move heat faster than microwaves and more aggressively than most ovens. That is an advantage for crisping—but it becomes a liability if you dial your usual 200°C (400°F) “cook temp” for a slice of pizza or a piece of fried chicken. The fix is lower air-fryer temperature + shorter windows, checking often, and using a thermometer on anything that was originally poultry, stuffing, or mixed dishes.

Reheat Temperature and Time Chart

These ranges assume food was fully cooked and cooled safely (refrigerated within 2 hours, stored at 4°C / 40°F or below). Times vary by thickness, basket size, and model—check early the first time you reheat a new dish.

If your air fryer runs hot (many basket models do), use the bottom of each range for temperature and check 1–2 minutes early. The brand converter explains how model calibration shifts effective heat.

Reheat Pizza in an Air Fryer

Cold pizza is dense and the cheese sets hard. At 175°C (350°F), a thin slice usually needs 3–4 minutes; a thick slice or deep-dish wedge may need 5–6 minutes.

What works: Place the slice cheese side up on parchment or directly on the perforated basket—avoid stacking. If the bottom browns before the cheese softens, next time start at 170°C (340°F) for 4–5 minutes.

What fails: Cooking pizza at 200°C+ to “speed it up” chars the underside and toppings before the cold center relaxes. Microwaves ruin crust; air fryers fix crust—only if the temperature stays moderate.

Reheat Fried Chicken in an Air Fryer

Arrange pieces skin-side up in a single layer at 175°C (350°F). Boneless tenders: 3–5 minutes. Thighs and drumsticks: 5–7 minutes. Large breast pieces: 6–8 minutes, checking at 6.

The coating should sound crisp when tapped; the meat must reach 74°C (165°F) in the thickest part for food safety on poultry. If the skin is browning too fast, drop to 165°C (330°F) and add 2–3 minutes.

Do not spritz oil on already-greasy fried chicken—it often makes the crust soggy, not crisp.

Safe Internal Temperatures After Reheating

Per USDA guidance, leftovers should reach 74°C (165°F) all the way through when reheated. That includes poultry, ground meat, casseroles, stuffing, rice dishes, steaks, chops, and mixed leftovers.

An instant-read thermometer is the only reliable check. Color and steam are helpful signals but not substitutes for temp on dense leftovers.

Six Mistakes That Ruin Reheated Food

1. Using full “cook” temperatures. 200°C (400°F) is for raw chicken and frozen fries, not yesterday’s roasted vegetables. It dries edges before the center warms.

2. Overcrowding the basket. Air fryers need airflow. Stacked pizza slices or piled fries create steam pockets—soggy centers, uneven heat. Single layer, batch if needed.

3. Reheating without a quick preheat. A cold basket adds 1–2 minutes of guesswork. Preheat 2–3 minutes at your reheat temperature before adding food (especially pizza and breaded items).

4. Ignoring moisture on rice and pasta. Plain rice reheated dry turns hard in minutes. Add a tablespoon of water per cup of rice and stir halfway. Loose casseroles benefit from a foil tent for the first half of the time.

5. Walking away during the last 2 minutes. Reheat windows are narrow. The difference between “crisp” and “cardboard” is often 60–90 seconds. Set a timer and check visually at the low end of the range.

6. Reheating food that sat out too long. If perishable food stayed above 4°C (40°F) for more than 2 hours (1 hour above 32°C / 90°F), do not reheat—discard. No appliance makes unsafe food safe again.

Practical Tips

Spritz, don’t soak. Dry fries and dry pizza crust benefit from a very light oil mist. Wet surfaces steam instead of crisp.

Foil for saucy items. Small portions of lasagna or saucy pasta can be wrapped loosely in foil for the first half of the time, then opened to re-crisp the top.

Convert from oven “reheat” instructions. If a package says “reheat in oven at 175°C for 15 minutes,” the air fryer is usually faster—start at 70% of the time and the same or slightly lower temperature, then adjust. The oven to air fryer converter is tuned for raw-to-cooked conversions; for reheating, prefer the chart above over blind math.

Scale batch size mentally. Doubling the mass in one basket increases time non-linearly—often +40–60%, not +100%. When in doubt, cook in two batches for even results. The serving / scaling guide helps when you’re scaling original recipe portions, not just reheating one plate. Thicker pieces need more time per gram of cold mass—the cooking time by weight tool is useful when you’re reasoning about a large roast or breast portion, not thin slices.

Use °C internally, display what you prefer. If a recipe or thermometer uses only one unit, the °C / °F converter keeps you aligned with your air fryer dial.

Use the oven to air fryer converter when adapting raw oven recipes—not for reheating, where lower temps rule. For frozen uncooked items straight from the freezer, see the frozen food air fryer guide. Model-specific heat differences are covered in the brand converter.
