The short answer
- To reheat pizza in an oven, preheat a sheet pan or stone to 375-425°F, set the slices on it and heat 8-10 minutes, until the cheese bubbles and the crust crackles.
- Preheating the pan is the whole trick: a hot surface re-crisps the bottom, while a cold pan steams it soft.
- Leftovers should be reheated to 165°F (USDA) and eaten within 3-4 days of refrigeration.

Here is how to reheat pizza in an oven: preheat a sheet pan to 375-425°F, put the slices on the hot pan and heat them 8-10 minutes, until the cheese bubbles and the crust crackles. The oven beats the microwave because dry heat re-crisps the base. If you already bake on a stone, the best outdoor pizza oven for leftovers and fresh pies alike uses the same hot-surface trick, only faster.
How do you warm up pizza in the oven?
Heat the surface first, then the pizza. A cold pan sits under the slice and steams the bottom, which is where soggy crust comes from. A pan that has preheated with the oven starts crisping the moment the slice lands.
- Take the leftover pizza slices out of the fridge while the oven heats; 10-15 minutes helps them warm evenly.
- Put a baking sheet, cast-iron pan or pizza stone on the middle rack and preheat the oven to 400°F.
- Lift the hot pan out, line it with parchment if you like and lay the slices on it, not touching.
- Return it to the middle rack and heat 8-10 minutes, until the cheese is melted and bubbling.
- Rest the slices a minute so the cheese settles, then eat.
Skip the cold pan
Loading slices onto a cold sheet pan and then preheating is the classic mistake. The pan and the pizza warm together, the bottom never browns and the crust turns chewy.
What temperature should you reheat pizza at?
Most guides land between 350 and 450°F. Lower heat is gentler on a thick crust and heats the middle through; higher heat crisps thin slices fast but can scorch the toppings. For an ordinary slice, 400°F is the dependable middle.
| Pizza | Oven temp | Time |
|---|---|---|
| Thin slice | 400-425°F | 6-8 min |
| Thick or deep-dish | 350-375°F | 12-15 min |
| Whole pizza | 350°F | 15-20 min |
| Frozen slice | 375-400°F | 12-15 min |
These are starting points; ovens differ, so check the cheese and crust rather than the clock.
How long does it take to reheat pizza at 350 degrees?
About 10-15 minutes for a slice, and 15-20 for a whole pizza. At 350°F the oven heats gently, which suits thick, topping-heavy slices, but a thin crust takes longer to crisp. If you only have 350°F because something else is baking, add a couple of minutes and move the slices to the top rack for the last stretch.
Can you reheat pizza on a pizza stone or steel?
Yes, and it is the best way to get that fresh-baked base. Put the stone or steel in the oven while it heats to 450-500°F, slide the slices on and give them 3-5 minutes. The slab stores heat and crisps the bottom almost instantly, which is why a stone is the best surface for leftovers. Never put a cold stone into a hot oven, and if yours is dirty, this guide on how to clean a pizza stone covers brushing off crumbs without soap.
In an outdoor pizza oven, do not use the full baking heat. Wait until the floor has cooled well below its 800-900°F peak, or turn the flame low, and a slice needs only a minute or two. At full heat the topping chars before the middle warms.
How do you reheat pizza without it going hard?
Hard, dry pizza comes from too much time or too little moisture. Three habits fix it:
- Cover a whole pizza loosely with foil for the first 10 minutes, then remove it so the top browns.
- Set a small oven-safe dish of water on the lower rack. The steam keeps cheese and toppings from drying out.
- Pull the pizza as soon as the cheese bubbles. Extra minutes only toughen the crust.
Thick crusts and heavy toppings suit foil; thin crusts do better uncovered on a hot pan.
Is it safe to reheat leftover pizza?
Yes, if it was handled properly. The USDA says perishable food should not sit out more than 2 hours (1 hour above 90°F), that refrigerated leftovers keep 3-4 days and that leftovers should be reheated to 165°F. An instant-read thermometer in the thickest part settles it; slices that are steaming hot in the middle with bubbling cheese are usually there. Throw out a pizza that sat out overnight.
Reheat once
Warm only the slices you plan to eat. Repeated cooling and reheating adds time in the temperature range where bacteria grow, and the crust degrades each round.
Oven, toaster oven, microwave or skillet?
Reheating pizza in the oven wins for a crisp base and for batches. A toaster oven does the same job for one or two slices, and an air fryer is a quick method for a single slice at 350°F for 3-4 minutes. A skillet over medium heat with a lid gives the crispest bottom in a few minutes, while a microwave is quick but leaves the crust soft and rubbery instead of crispy.

Frequently asked questions
How long does it take to reheat pizza in the oven at 350 degrees?
Usually 10-15 minutes for a slice on a preheated sheet pan. At 350°F the crust crisps more slowly, so 400°F for 8-10 minutes is the better balance of crisp and melted cheese.
Can you reheat pizza after it has been in the fridge?
Yes. The USDA says refrigerated leftovers are good for 3-4 days and should be reheated to 165°F. Cold pizza straight from the fridge needs a minute or two more than one left to sit for 10 minutes.
How do you keep pizza warm in the oven?
Set the oven to its lowest setting, often around 200°F, and keep the pizza on a rack or pan, uncovered. It holds for a short while, but the crust slowly dries, so eat it within about half an hour.
Can you reheat frozen pizza in the oven?
Yes. Reheat frozen slices straight from the freezer on a preheated pan at 375-400°F, allowing 12-15 minutes. Thawing first is optional, and the crust crisps best from a hot start.
How can I reheat pizza that was left out?
Check the clock first. The USDA says perishable food should not sit out more than 2 hours, or 1 hour above 90°F. Pizza left out longer than that should be thrown away, not reheated.
