Yes — the air fryer is one of the best tools for reheating leftovers, especially fried and crispy foods. The circulating hot air restores crispiness that a microwave destroys with steam. Most leftovers reheat at 350–375°F for 3–8 minutes. The trade-off is a few extra minutes compared to a microwave.
Best foods to reheat in an air fryer
The air fryer excels at reheating: pizza (3–4 min at 350°F — crispy crust, melted cheese), fried chicken (5–8 min at 370°F — restored crunch), French fries (3–5 min at 400°F), egg rolls and spring rolls (3–4 min at 370°F), mozzarella sticks (3–4 min at 375°F), and any other breaded or fried food. The rule of thumb: if the original food was crispy, the air fryer restores it. If it was soft (mashed potatoes, soups, casseroles), use a microwave.
Temperature and time guide for reheating
Pizza: 350°F, 3–4 minutes. Fried chicken pieces: 370°F, 5–8 minutes. French fries: 400°F, 3–5 minutes, shake halfway. Egg rolls / spring rolls: 370°F, 3–4 minutes. Chicken wings: 375°F, 4–6 minutes. Burgers: 350°F, 3–5 minutes. Pasta bakes (in a pan): 325°F, 5–8 minutes. All proteins should reach 165°F (74°C) internal temperature per USDA guidelines.
Foods that do not reheat well in an air fryer
Avoid reheating these in the air fryer: soups, stews, chilis, and sauces (liquid will drip through the basket or dry out completely). Leafy salads (the greens wilt immediately). Cream-based pasta dishes (the sauce dries and splits). Very delicate baked goods like custard tarts or cream puffs (the custard overcooks before the pastry reheats). For these, a microwave or stovetop is better.
Food safety when reheating
The USDA requires all reheated leftovers to reach an internal temperature of 165°F (74°C). Use an instant-read thermometer for thicker items (chicken, meat portions) rather than relying on appearance or time alone. Leftovers should be reheated only once — do not reheat the same item repeatedly.

What temperature should you reheat leftovers in the air fryer?
Most leftovers reheat well at 350°F (177°C) for 3–8 minutes depending on thickness. Pizza takes 3–4 minutes at 350°F. Chicken pieces take 5–8 minutes at 370°F. Fried foods (fries, nuggets, fried chicken) reheat best at 375–400°F for 3–5 minutes to restore crispiness. The USDA recommends reheating leftovers to an internal temperature of 165°F (74°C). Avoid reheating liquids or soups — the air fryer is not designed for liquid-based dishes.
Does reheating in an air fryer make food crispy again?
Yes — this is one of the air fryer's best uses. The circulating hot air drives off surface moisture that makes reheated food soggy in a microwave. Fried chicken, French fries, pizza, egg rolls, and spring rolls all regain most of their original crispiness when reheated in the air fryer at 375–400°F for 3–5 minutes. The microwave reheats food faster but steams it, destroying crispiness. The air fryer adds 3–5 minutes but restores texture. The only caveat: very saucy dishes reheat better in a microwave.
Which types of leftovers reheat best in an air fryer compared to a microwave?
Fried and breaded items — french fries, fried chicken, egg rolls, onion rings, and pizza — are where an air fryer completely outperforms a microwave, restoring actual crispiness instead of creating a soggy texture. Roasted vegetables, grilled meats, and casseroles also reheat well with better texture. The microwave still wins for speed on soft, saucy dishes like soups, stews, and mashed potatoes, where crispiness is not the goal.
