To keep pizza warm in the oven, set it to its lowest setting, usually 170°F to 200°F (about 75°C to 95°C), take the pizza out of the box, place it on a baking sheet or directly on the oven rack, and cover it loosely with foil. It’ll stay hot without drying out for about 30 minutes to an hour. Don’t put the cardboard box in the oven.
That last point is the one people ask about most, so we’ll cover it properly, along with how to keep the crust crisp instead of soggy.
Step-by-step: keeping pizza warm in the oven
- Preheat the oven to its lowest temperature, around 170°F to 200°F.
- Take the pizza out of the box.
- Put it on a baking sheet, a pizza pan or straight onto the middle rack. A rack keeps the bottom crispest.
- Cover loosely with aluminum foil to stop the top drying out. Don’t wrap it tightly, or steam will soften the crust.
- Keep it in for up to about an hour. Check it after 30 minutes.
- If the cheese starts to look dry, pull it out. Longer than that and quality drops fast.
If you have a pizza stone, put it in while the oven preheats and slide the pizza onto it. It holds heat evenly and keeps the base crisp.
Can you put a pizza box in the oven?
You shouldn’t. Even though the oven is on a low setting, it’s not a good idea, for three reasons:
- Fire risk. Paper and cardboard can ignite at temperatures somewhere around 400°F to 450°F. Your oven might be set to 200°F, but heating elements and gas flames get much hotter than the air temperature, and a box touching or sitting close to them can scorch or catch fire.
- Inks and coatings. Pizza boxes are printed and sometimes coated. They’re designed to hold hot food, not to be baked.
- It doesn’t work well. Cardboard insulates, so the pizza warms more slowly inside the box, and trapped steam makes the crust soggy.
Some people say they’ve done it without any problems at very low temperatures. It’s still a risk you don’t need to take, when moving the pizza onto a baking sheet takes ten seconds.
What temperature keeps pizza warm?
| Oven setting | Result | How long |
|---|---|---|
| 150°F to 170°F | Warm, very gentle | Up to about an hour |
| 170°F to 200°F | Hot and ready to serve, the best range | 30 to 60 minutes |
| 225°F to 250°F | Starts to cook further and dry out | 15 to 20 minutes max |
| 350°F and above | Reheating, not holding | 5 to 10 minutes |
From a food safety point of view, hot food should be held at 140°F (60°C) or above. Pizza that’s been sitting at room temperature for more than two hours should go in the fridge rather than back in the oven.
Other ways to keep pizza warm
Leave it in the box, off the oven
If you’re eating within 20 to 30 minutes, the box itself does a decent job. Corrugated cardboard is a good insulator. Keep the lid closed, and put the box somewhere warm, like on top of (not inside) the stove while the oven is on.
Use a warm towel or insulated bag
Wrap the closed box in a thick towel or put it in an insulated food bag. Delivery drivers use insulated bags for exactly this reason.
Keep it on a warm pan
For a party, keep a few slices on a preheated baking sheet on the counter, and swap trays in and out of the low oven as people eat.
Slow cooker on warm
A slightly unusual one: lay a sheet of parchment in a large slow cooker set to warm and stack slices with parchment in between. It keeps slices warm for a while, though the crust softens.
How to keep pizza crust crispy
- Vent the steam. Sogginess comes from moisture. If the pizza sits in the box, open the lid slightly for a minute to let steam escape.
- Use the rack. A pizza directly on the oven rack stays crispier than one on a solid tray.
- Don’t stack pizzas. Stacked boxes trap heat and steam between them.
- Skip the microwave. It heats the water in the dough and makes the crust chewy.
Reheating leftover pizza
| Method | Temperature | Time | Result |
|---|---|---|---|
| Oven | 375°F to 400°F on a preheated tray | 8 to 10 minutes | Crisp base, melty cheese |
| Skillet | Medium heat, lid on for the last minute | 4 to 6 minutes | Crispiest base |
| Air fryer | 350°F | 3 to 4 minutes | Quick and crisp |
| Microwave | High | 30 to 60 seconds | Fast but soft crust |
Why good pizza boxes matter for heat
The box plays a big part in how hot a pizza arrives. Corrugated board traps heat between its fluted layers, small vent holes let steam out so the crust doesn’t go soggy, and a snug fit stops the pizza sliding around. Grease-resistant coatings keep the box strong when it’s carrying hot, oily food.
If you run a pizzeria, food truck or frozen pizza brand, we make custom pizza boxes in corrugated board with food-safe inks, plus frozen pizza boxes and pizza bags. If you’re curious about what goes into the board itself, read what cardboard is made of.
Frequently asked questions
Use the lowest setting, usually 170°F to 200°F (75°C to 95°C). That keeps it hot without cooking it further.
About 30 minutes to an hour. After that, the cheese and crust start to dry out.
It’s not recommended. Even at low settings, heating elements can get hot enough to scorch cardboard, and the box traps steam. Move the pizza to a baking sheet instead.
Cardboard and paper typically ignite somewhere around 400°F to 450°F, depending on the material and conditions. Direct contact with a flame or heating element can scorch it faster.
Keep it in the closed box wrapped in a towel or insulated bag, or on a preheated baking sheet. For longer holds, a slow cooker on the warm setting works too.
