How to reheat pizza so the crust stays crispy comes down to one thing: dry heat applied straight to the underside of the slice. Preheat the oven to 375°F (190°C) and slide the pizza onto a baking sheet that has been heating for 10 minutes, or set a slice in a dry skillet over medium heat. The oven takes 8 to 12 minutes for several slices. A skillet takes about 3 minutes for one or two. Skip the microwave unless you are truly out of options.
This is the week after pizza night, when the box is still on the counter and everybody is pretending the leftover slice is fine cold. It is good cold. It is also better with a hot, dry pan. Here is how to reheat pizza every way, what temperature to use, and how long to give each crust style.

How to Reheat Pizza So the Crust Stays Crispy: Quick Guide
The single rule behind every method below: preheat the pan, give the crust direct contact with hot metal, and keep the time short enough that the toppings do not dry out. Long heat does not make a crust crispier, it just makes the cheese tough.
| Method | Temperature | Time | Crust result | Best for |
|---|---|---|---|---|
| Skillet | Medium heat, dry pan | 2 min uncovered, 1-2 min covered | Crispiest base of any method | 1-2 slices |
| Oven | 375°F (190°C) | 8-12 min | Evenly crisp, holds well | 3+ slices or a whole pie |
| Toaster oven | 350°F (175°C) | 5-7 min | Crisp, no full preheat | 1-3 slices |
| Air fryer | 350°F (175°C) | 3-5 min | Very crisp edges, fast | 1-2 slices |
| Microwave | High | 20-30 sec | Soggy unless finished | Emergency only |
The Best Way to Reheat Pizza for a Crispy Crust
The best method for most people is a preheated oven at 375°F (190°C) with a baking sheet that has been heating inside it for at least 10 minutes. A cold sheet absorbs heat from the pizza instead of giving it back, which is exactly how you end up with a pale, soft base.
Where the slice sits matters less than the temperature of what it sits on. Parchment or a light spray of oil stops the cheese from welding itself to the metal. Skipping both and putting the pizza straight on a screaming-hot sheet gives you the best crust of the oven method, and cleanup is a soak rather than a scrub.
Here is the part most guides skip. When pizza cools, moisture from the sauce and cheese migrates into the dough, and the baked starches recrystallize into a dense, chalky network. That is why day-old crust is tough, not just soft. Direct bottom heat drives that trapped moisture back out and restarts browning on the underside. A microwave runs steam through a still, cool chamber instead, so the crust steams itself soft and then sits there rubbery. Bottom heat, not more heat, is the fix.
Cast iron holds and delivers heat more evenly than nonstick, which is why it wins for a single slice, but a good nonstick skillet is close behind. No oil is required for a pizza that already has sauce and cheese on the bottom.
How to Reheat Pizza in the Oven
The oven is the right call when you are reheating half a pie or more. It heats from both directions, so the toppings get hot without the base needing extra time, and it does not demand constant attention.
- Set the oven to 375°F (190°C) and let it run for at least 10 minutes.
- Put a baking sheet inside to preheat with the oven. A cold sheet is the number one reason oven-reheated pizza stays soft underneath.
- Place the slices on the hot sheet in a single layer. Touching slices steam each other instead of browning.
- Bake for 8 to 12 minutes, until the cheese is fully melted and the underside feels firm and golden when you lift an edge with a spatula.
- For a whole pie, use two sheets or bake in two rounds. Crowding drops the temperature and gives you steamed crust.
If the cheese edges brown before the middle is hot, tent the pizza loosely with foil for the first half of the time, then pull it off for the last few minutes. That keeps the topping from scorching without trapping steam.
Owning a pizza stone or pizza steel pushes this further. Set it at 475°F (245°C) and the crust comes back with a chew and char closer to a pizzeria. The catch is the 30 to 45 minute preheat, so it is a weekend move rather than a Tuesday lunch. My picks are in the 8 best pizza stones for crispy crust roundup.
How to Reheat Pizza in a Skillet for an Extra-Crispy Bottom
A skillet gives you the crispest base in the least time, and it is the method most home cooks describe once they try it. It is a two-phase job: crisp the bottom dry, then steam the top under a lid.
- Put a dry nonstick or cast iron skillet over medium heat for a minute until it is hot but not smoking.
- Lay the slice in crust-first. Cook uncovered for about 2 minutes, until the bottom looks deep golden and feels firm.
- Add a teaspoon of water to the far side of the pan, away from the crust, so it steams and does not wet the base.
- Cover with a lid, or tent with foil, and cook 1 to 2 more minutes until the cheese melts and the toppings are steaming hot.
- Lift the slice out and let it sit on the pan for 30 seconds so the base finishes drying.
Two slices fit in a 12-inch skillet if you angle them. Three is where crowding turns the pan into a steamer, and the bottoms never quite get there.
Thick and deep-dish slices need a longer first phase, about 4 minutes uncovered before the water goes in. They also do better if you cut them in half so the heat reaches the center instead of hiding cold in the middle.
Reheating Pizza in an Air Fryer
The air fryer is the fastest truly crisp method, and it is close to a convection oven pointed at a small slice. The dry, moving hot air drives off surface moisture quickly, which is why the crust browns so well.
- Preheat the air fryer to 350°F (175°C) for 3 minutes.
- Place one or two slices in the basket in a single layer, crust down.
- Cook for 3 to 5 minutes, checking at the 3-minute mark. The cheese should be melted and blistered, the crust crisp through.
- Add 1 to 2 more minutes only if the base is still pale.
Thin crust reheats faster and crisps better at 400°F (205°C) for about 2 minutes. The usual complaint with air fryers is browned edges while the middle is still cool, and that is a basket size problem, not a temperature problem. If the slices touch or the basket feels packed, do two rounds. No oil is needed, but a very light spray on the crust helps a very dry slice.
How to Reheat Pizza in the Microwave Without a Soggy Crust
The microwave is the fastest and the worst option, and the problem is physics rather than technique. A microwave heats water molecules, and in a cool, still chamber that water becomes steam that never escapes. The crust softens, the cheese turns rubbery, and the slice comes out limp with a floppy tip.
If you have 30 seconds and a skillet, use the hybrid that gets passed around on cooking forums. Microwave the slice for 25 to 30 seconds to warm and melt the toppings, then set it straight into a dry medium skillet for about 90 seconds until the bottom crisps. You get melted cheese from the microwave and a crust from the pan.
A toaster oven works the same way. Put the microwaved slice on the rack at 350°F (175°C) for 4 to 5 minutes.
A paper towel under the slice absorbs condensation and keeps the topping from dripping, and it is worth doing. What it cannot do is crisp anything. It solves a wet plate, not a soft crust. If you want soft pizza on purpose, cold slices are genuinely good, and there is nothing wrong with eating the box standing over the sink.
Reheating Thin-Crust, Thick-Crust, and Frozen Pizza
Slice thickness changes the timing far more than pizza style does. A thin crust dries out before a deep-dish center gets hot, and every method below assumes a fully preheated pan or oven.
| Pizza type | Oven temp | Time | Watch for |
|---|---|---|---|
| Thin crust | 350°F (175°C) | 6-8 min | Cheese bubbling at the edges |
| Regular crust | 375°F (190°C) | 8-12 min | Base firm when lifted |
| Thick or pan | 375°F (190°C) | 12-15 min | Cut a slit to check the center |
| Deep dish | 375°F (190°C) | 15-18 min | Foil tent for the first 5 min |
| Calzone | 350°F (175°C) | 10-12 min | Bottom crisps before the filling warms |
| Frozen slice, no thaw | 400°F (205°C) | 10-12 min | Direct from freezer to hot sheet |
Frozen slices go straight into the hot oven. Letting them thaw first puts moisture on the crust that then has nowhere to go. A frozen slice also likes the preheated sheet more than most, because there is more ice water to drive off.
How you stored the pizza decides how it reheats. Cool slices fully before stacking, layer parchment or wax paper between them, and refrigerate in an airtight container for 3 to 4 days. Freeze individual slices flat in a bag for up to 2 months. If you are turning Friday night pizza into something else, the crispy leftover remakes ideas are worth a look, since a reheated slice turns into a great breadcrumb.
Reheat leftovers to steaming hot throughout, which means 165°F (74°C) in the center, and refrigerate any pizza that sat out more than two hours.
Common Mistakes That Make Reheated Pizza Soggy
- A cold pan. Preheat the skillet or the sheet for 10 minutes. A cold surface steals the heat the crust needs.
- Reheating in the delivery box. Cardboard absorbs moisture, and the box traps steam. If you must use it, slide the slices onto a tray first.
- Cranking the oven to its maximum. Broiling burns the cheese before the center heats and dries out the toppings. 375°F (190°C) is the working number.
- Stacking slices. Overlapping pieces steam each other. Every slice needs its own contact with the pan.
- Skipping the preheat. Most ovens take 15 to 20 minutes to reach temperature. That wait is most of the work.
- Adding fresh toppings before reheating. Extra sauce or wet toppings add the exact moisture you are trying to remove. Add fresh basil, Parmesan, red pepper flakes or a drizzle of hot honey after it comes out of the pan.
- Leaving it on the heat after the cheese melts. Cheese stops improving at melted and starts drying out right after. Pull it the moment the base is firm.
Frequently Asked Questions
What temperature is best for reheating pizza so the crust stays crispy?
375°F (190°C) in a conventional oven is the sweet spot for most leftover pizza. It browns the crust without drying out the toppings. Drop to 350°F (175°C) for thin crust, which burns before it crisps, and go up to 475°F (245°C) on a preheated pizza stone if you have one and a half hour to spare.
Is it okay to reheat pizza on the cardboard box?
Skip it. Cardboard drinks up the moisture the crust releases and traps the steam, so the base comes out softer than when it went in. It is also scorched by direct oven heat. Slide the slices onto a baking sheet or a preheated pizza stone instead and keep the box for storage.
How long does reheated pizza stay crispy?
A properly reheated slice holds its crisp base for about an hour at room temperature before the crust starts to relax again. The topping reheats faster than the crust, so eat it while the base is still firm. For longer storage, let it cool, then refrigerate it airtight where it will keep 3 to 4 days.
Is the air fryer better than the oven for reheating pizza?
For one or two slices, yes. At 350°F (175°C) for 3 to 5 minutes the air fryer gets there faster than a full oven and browns the edges nicely. For a half pie or more, the oven wins because the air fryer basket is too small and crowded slices come out steamed.
Does adding more cheese or toppings before reheating help?
It does not help the crust, and it works against it. Fresh toppings add moisture, which softens the base. A light sprinkle of dry grated Parmesan is the exception since it browns without releasing water. Save basil, garlic oil, pepper flakes and hot honey for after the slice leaves the pan.
Can you reheat the same pizza slice twice?
You can, and the second reheating is usually blander and drier than the first. The crust has already lost most of its moisture. Reheat gently, check the base after two minutes in the skillet, and add a few drops of water under the lid if the toppings need help. The food-safety side is fine as long as the slice has stayed refrigerated.
Conclusion
Start with a preheated oven at 375°F (190°C) and a baking sheet that has been heating for 10 minutes, and you will get a crisp base on any slice. For one or two pieces, the skillet is faster and crisper: 2 minutes dry, a teaspoon of water, then 1 to 2 minutes under the lid.
From there it is all about adjusting for the slice in front of you. Thin crust needs less time and more heat, thick and deep-dish need more time and a foil tent, and the microwave only earns its place when a 30-second warm-up gets you to a skillet or toaster oven afterward. That is how to reheat pizza so the crust stays crispy, and it takes less time than most people spend complaining about it.
