Reheating pizza in an air fryer takes just 3 to 5 minutes at 350°F, and the crust comes back surprisingly crisp. That short window is exactly why so many people now ask how long to warm up pizza in the air fryer instead of reaching for the microwave or oven.
The microwave makes the crust soft and chewy. A regular oven takes 10 to 15 minutes and heats up your whole kitchen. The air fryer sits right in the middle — fast like a microwave, crispy like an oven.
Below you will find exact times, temps, and simple steps for different pizza types. You will also learn how to avoid the common mistakes that ruin leftover slices.
How Long To Warm Up Pizza In The Air Fryer
The short answer: 3 to 5 minutes at 350°F (175°C) for a standard slice. Thicker slices or deep dish may need 5 to 7 minutes. Thin crust can be done in as little as 2 to 3 minutes.
These times are for a preheated air fryer. If you skip preheating, add about 1 to 2 minutes. Always check your pizza at the 3 minute mark the first time you try a new air fryer model, since wattage varies between brands.
Quick Time And Temperature Chart
- Thin crust slice: 2 to 3 minutes at 350°F
- Regular hand tossed slice: 3 to 4 minutes at 350°F
- Thick crust or pan pizza: 5 to 6 minutes at 350°F
- Deep dish slice: 6 to 8 minutes at 340°F
- Two slices side by side: 4 to 5 minutes at 350°F
- Frozen pizza slice: 6 to 8 minutes at 360°F
Notice that frozen slices take longer. The ice inside the toppings has to melt and then heat through before the crust can crisp up. Do not crank the temp above 375°F to speed things up. The cheese will burn before the middle gets hot.
Why The Air Fryer Works So Well For Pizza
An air fryer moves hot air around the food at high speed. That moving air pulls moisture off the surface of the crust. Dry surface plus high heat equals crisp crust. It is the same science behind a convection oven, just in a smaller space.
The small basket also means the air stays close to the food. There is nowhere for the heat to escape, so the slice reheats fast without drying out the cheese. This is why 3 to 5 minutes is enough when a full oven needs triple that time.
Step By Step: How To Reheat Pizza In An Air Fryer
- Preheat the air fryer at 350°F for 2 to 3 minutes. This step matters more then most people think.
- Place the slice in the basket in a single layer. Do not stack slices.
- Leave a little space between slices so air can flow around each one.
- Set the timer for 3 minutes and start checking.
- Add 1 minute at a time if the middle is still cold.
- Pull the slice out when the cheese bubbles and the bottom feels firm.
- Let it rest on a plate for 30 seconds before eating. The inside is very hot.
If you want extra insurance against a soggy bottom, put a small square of parchment paper under the slice. Poke a few holes in it so air still moves underneath. Never use loose parchment without weight on it, since it can fly up into the heating element.
Should You Use Foil In The Air Fryer
Foil works, but it blocks airflow on the bottom. That means the crust will not crisp as well. If you use foil, keep it flat and do not wrap the slice. Many people skip foil altogether and just wipe the basket after. That gives the best crust every time.
How To Keep The Cheese From Burning
Cheese burns fast in an air fryer because the heating element sits close to the food. A few simple tricks help:
- Keep the temp at 350°F or lower for cheesy slices
- Add a tiny splash of water to the basket edge, not on the pizza, to add steam
- Cover the slice loosely with foil for the first 2 minutes if the cheese is thick
- Pull the slice as soon as the cheese starts to bubble, not after
If your air fryer runs hot, drop to 340°F and add one extra minute. Every unit is a little different. Once you learn yours, you can hit the perfect slice every time without thinking about it.
Times For Different Types Of Pizza
Reheating Thin Crust Pizza
Thin crust is the fastest. Two to three minutes at 350°F is usually all it needs. Any longer and it turns into a cracker. Check it at 2 minutes. If the cheese is melted, it is done.
Reheating Thick Crust And Pan Pizza
Thick crust holds more moisture, so it needs more time. Use 350°F for 5 to 6 minutes. If the top browns too fast, lower the temp to 330°F and give it another 2 minutes. The goal is to heat the center without burning the top.
Reheating Deep Dish Pizza
Deep dish is basically a pie. The middle stays cold long after the outside is hot. Set the air fryer to 340°F and plan on 6 to 8 minutes. You can also cover it with foil for the first 4 minutes, then remove the foil to crisp the crust.
Reheating Frozen Pizza Slices
Frozen slices need 6 to 8 minutes at 360°F. Do not thaw them first. Going straight from freezer to air fryer gives the best result. Flip once at the halfway point so both sides heat evenly.
Common Mistakes To Avoid
- Stacking slices on top of each other. The bottom slice steams instead of crisps.
- Skipping the preheat. Cold basket equals soggy crust.
- Setting the temp too high. 400°F burns the cheese in under 2 minutes.
- Walking away. Three minutes goes by fast and pizza can go from perfect to burnt quick.
- Using too much oil. A light spray is fine, a drizzle makes the crust greasy.
One more tip: reheat the slice whole, not cut into small pieces. Small pieces dry out and the edges get hard. Keep the slice intact and cut it after it comes out.
Air Fryer Vs Microwave Vs Oven
The microwave wins on speed but loses on texture. Thirty seconds gives you hot pizza with a rubbery crust. The oven gives great texture but takes 10 to 15 minutes plus preheat time. The air fryer gives you oven quality in about 4 minutes with no preheat needed in most models.
For one or two slices, the air fryer is the clear winner. For a whole pizza, the oven still makes more sense because you can fit more at once. Match the tool to the job and you will get better results every time.
Final Tips For Perfect Leftover Pizza
Store leftover pizza in the fridge in a sealed container or wrapped tight in foil. It keeps for 3 to 4 days. After that, the quality drops fast and it is safer to toss it.
When you reheat, start with less time then you think you need. You can always add 30 seconds. You can not undo a burnt slice. With a little practice, 3 to 5 minutes at 350°F will become your go to number, and your leftover pizza will taste almost as good as the first night.
