Reheating pizza in an air fryer restores its crispy crust and melted cheese better than microwaving. But how long do you heat up pizza in the air fryer? The short answer is 3 to 5 minutes at 350°F to 375°F, depending on the slice thickness and your model.
That small window of time is what makes the air fryer so good for leftovers. A microwave makes crust soggy in 60 seconds. An oven takes 15 minutes and heats up your whole kitchen. The air fryer sits right in the middle, fast and effective.
Below you will find exact times, temperatures, and simple steps for the best results every time.
How Long Do You Heat Up Pizza In The Air Fryer
Most slices need 3 to 5 minutes. Thin slices cook closer to 3 minutes. Thick, loaded slices with heavy toppings need 5 to 6 minutes. Frozen pizza takes longer, around 8 to 12 minutes, because it starts cold all the way through.
The exact time also depends on your air fryer wattage. A 1500-watt unit runs hotter and faster than a small 1000-watt model. Start with 3 minutes, check the slice, then add 1 minute at a time if needed.
Quick Time Chart By Pizza Type
- Thin crust slice: 3 minutes at 375°F
- Regular hand-tossed slice: 4 minutes at 360°F
- Thick pan or deep dish slice: 5 to 6 minutes at 350°F
- Two slices side by side: 4 to 5 minutes at 360°F
- Frozen pizza slice: 8 to 10 minutes at 360°F
- Whole small frozen pizza: 10 to 12 minutes at 360°F
These times assume a preheated basket. If you skip preheating, add about 1 minute to each number.
Best Temperature For Reheating Pizza
Set your air fryer between 350°F and 375°F. This range melts the cheese again without burning the crust. Going above 400°F can char the edges before the middle gets hot. Going below 325°F dries out the slice before the cheese softens.
For thick slices, stay at 350°F. For thin slices, 375°F gives a faster, crispier finish. When in doubt, 360°F is a safe middle ground for any slice.
Step-By-Step: Reheating Pizza In An Air Fryer
- Preheat the air fryer at 360°F for 2 to 3 minutes. This step matters more than most people think.
- Place the slice in the basket in a single layer. Do not stack slices.
- Leave a little space between slices so hot air moves around each one.
- Set the timer for 3 minutes and let it run.
- Check the slice at the 3-minute mark. The cheese should be bubbling and the crust firm.
- Add 1 more minute if the center is still cool.
- Remove with tongs and let it rest for 30 seconds before eating.
That last step is not filler. The rest lets the heat spread evenly through the slice so the middle is not cold while the edges burn your mouth.
Should You Use Foil Or Parchment Paper?
You can line the basket with parchment paper for easy cleanup, but do not let it block airflow. Punch a few holes in it or cut it to fit the flat bottom only. Never use foil in an air fryer unless the manufacturer says it is safe. Loose foil can fly up into the heating element and cause damage.
For the crispiest crust, skip the liner entirely. The perforated basket lets hot air hit the bottom of the slice directly.
How To Keep The Crust Crispy
- Do not add oil or butter. The pizza already has enough fat.
- Place the slice cheese-side up. Flipping it makes a mess and does not help.
- Avoid overcrowding. Two slices max in a small basket.
- Reheat within 3 to 4 days of refrigeration for the best texture.
- If the top browns too fast, drop the temp to 340°F and add 1 minute.
Cold pizza straight from the fridge works fine. You do not need to let it sit out first. In fact, cold slices hold their shape better in the basket and are less likely to fall apart.
Common Mistakes To Avoid
Many people ruin leftover pizza in the air fryer with a few small errors. Here are the ones I see most often.
Not Preheating The Air Fryer
A cold basket means the first 2 minutes just warm the machine, not the food. Your slice ends up uneven, with a hot edge and a cool center. Always preheat, even for a single slice.
Setting The Timer Too Long
Air fryers cook fast. A slice left in for 8 minutes turns into a cracker with burnt cheese. Start short. You can always add time, but you cannot undo a burnt slice.
Stacking Slices
Stacked slices steam each other. The bottom slice gets soggy and the top one cooks unevenly. Use one layer only. If you have four slices, reheat them in two batches.
Using The Wrong Temperature
Too hot burns the crust. Too low dries the cheese into a rubbery sheet. Stick to 350°F to 375°F and you will avoid both problems.
Air Fryer Vs Other Reheating Methods
It helps to see why the air fryer wins for most people.
- Microwave: 45 to 60 seconds. Fast, but the crust turns soft and chewy.
- Oven: 10 to 15 minutes at 375°F. Good results, but slow and heats the kitchen.
- Skillet: 5 to 7 minutes on medium-low. Crispy bottom, but the cheese stays firm.
- Air fryer: 3 to 5 minutes at 360°F. Crispy crust and melted cheese in one step.
The air fryer is the only common method that fixes both the crust and the cheese at the same time. That is why it has become the go-to choice for leftovers.
What About A Toaster Oven Air Fryer Combo?
These units work the same way but often run a bit slower. Add 1 to 2 minutes to the times above. Use the air fry or convection setting, not plain toast or bake. The fan is what makes the crust crisp.
Tips For Larger Batches And Whole Pizzas
Reheating a whole pizza in an air fryer is tricky because most baskets are small. If your air fryer fits a whole 10-inch pizza, set it to 350°F for 6 to 8 minutes. Check it at the halfway point and rotate if your unit cooks unevenly.
For a large pizza that does not fit, cut it into quarters and reheat two pieces at a time. Each batch takes 3 to 4 minutes. This is faster than the oven and gives better results than the microwave.
If you are reheating several slices for a group, keep finished slices on a plate under a clean towel. They stay warm for about 10 minutes while you work through the batches.
Final Numbers To Remember
Keep this simple rule in your head. Thin slice, 3 minutes. Regular slice, 4 minutes. Thick slice, 5 to 6 minutes. Frozen slice, 8 to 10 minutes. All at 350°F to 375°F, always preheated.
Check at the low end of the range, add time in 1-minute steps, and let the slice rest briefly before you eat. Do that and your leftover pizza will taste close to fresh every single time.
