If you have ever been disappointed by microwave-reheated pizza or soggy leftover fries, an air fryer will change your life. The best air fryer for reheating food brings leftovers back to their original crispy glory in just a few minutes. From day-old pizza to last night's fried chicken, air fryers restore texture and flavor that microwaves simply cannot. Here are the models that do it best.
Microwaves heat food by exciting water molecules, which creates steam and makes crispy foods soggy. Ovens work but take 15 to 20 minutes including preheat time for a small portion of leftovers. Air fryers hit the sweet spot — they preheat in under 3 minutes and reheat most foods in 3 to 5 minutes while restoring crispiness. The circulating hot air re-crisps the exterior while gently warming the interior.
The Cosori Pro LE earns our top spot for reheating thanks to its dedicated reheat preset and quick startup. Simply press the reheat button and the air fryer selects the optimal temperature and time. The square basket fits leftover pizza slices perfectly — no folding or cutting required. The nonstick basket wipes clean in seconds, making it practical for daily reheating.
For singles and couples who primarily want an air fryer for reheating portions of leftovers, the Chefman TurboFry 3.5-Quart is an affordable and compact choice. It heats up quickly, fits on any countertop, and handles one to two servings of reheated food perfectly. The simple temperature dial and timer make operation completely straightforward.
The Ninja Air Fryer Pro offers four functions — air fry, roast, reheat, and dehydrate. The dedicated reheat function is specifically tuned to warm food without overcooking it. The 5-quart ceramic-coated basket is large enough for family-sized leftover portions and cleans easily even after reheating cheesy or saucy foods.
The Instant Vortex Mini is designed for smaller kitchens and everyday convenience. Its compact 4-quart size is ideal for reheating one to three servings of leftovers. Four one-touch smart programs simplify operation, and the EvenCrisp system ensures your reheated food is warmed through evenly. It is light enough to move in and out of a cabinet easily.
Pizza might be the single best food to reheat in an air fryer. Place slices in a single layer at 325°F for 3 to 4 minutes. The crust gets crispy, the cheese re-melts, and the toppings heat through. The result is better than fresh delivery pizza from most chains.
Spread leftover fries in a single layer at 375°F for 3 to 5 minutes. Shake once halfway through. They come out almost as crispy as when they were first served.
Reheat fried chicken at 375°F for 4 to 6 minutes. The breading re-crisps beautifully while the meat stays juicy inside. This method works for chicken tenders, wings, and drumsticks.
Egg rolls, spring rolls, crab rangoons, and fried rice all reheat well at 350°F for 3 to 5 minutes. Stir-fried dishes should be placed in an oven-safe dish.
Reheat steak at 300°F for 3 to 5 minutes for a gentle warm-through without overcooking. This low temperature preserves the original doneness.
Croissants, muffins, and pastries reheat at 300°F for 2 to 3 minutes. They emerge warm and flaky rather than tough.
For everyday reheating, the Cosori Pro LE offers the best combination of a dedicated reheat preset, perfect basket size, and easy cleanup. The Chefman TurboFry is unbeatable for budget buyers who mostly reheat small portions. If you want a model that also excels at cooking, the Ninja Air Fryer Pro provides the best all-around versatility. Once you start reheating in an air fryer, you will never go back to the microwave for crispy foods.
A microwave is faster for simply warming food, but an air fryer only takes 3 to 5 minutes for most items and produces dramatically better results. For crispy foods like pizza and fries, the extra minute or two is absolutely worth it.
Avoid reheating soupy or very saucy foods directly in the basket as they will drip through. Leafy salads and raw vegetables also do not reheat well. Delicate foods like soft fish fillets may dry out.
A brief 1-to-2-minute preheat can improve results, but it is not strictly necessary. Many foods reheat well when placed in a cold air fryer. Preheating is most helpful for pizza and breaded items.
Yes, aluminum takeout containers are safe in an air fryer. Remove the lid and make sure the container does not completely block airflow. This is a convenient way to reheat takeout directly in its packaging.
Use a lower temperature (300°F to 325°F), do not reheat longer than necessary, and lightly mist breaded foods with water or oil before reheating. Covering loosely with foil also helps retain moisture.
