Direct answer: To reheat pizza so the crust stays crisp, put the heat under the slice, not around it. For one or two slices, use a skillet on medium heat with a lid and a few drops of water in the pan away from the slice. For a lot of slices, use a preheated pizza steel or stone in a 450°F oven. An air fryer is a fast, good runner-up. The microwave gets pizza hot but leaves the crust soft. For safety, refrigerate leftover pizza within 2 hours, eat it within 3 to 4 days, and reheat to 165°F.

Leftover pizza has two problems: a crust that’s gone stale and leathery, and cold, set cheese. Heat that hits the top first, like a microwave or a cold sheet pan, melts the cheese while the crust steams. Heat from below re-crisps the crust, and a lid or a hot oven handles the top.

Reheating methods compared

Times and temperatures below come from the source named in each row. Ovens, burners, and air fryers vary, so treat them as starting points and watch the first slice.

Method	Best for	Crust result	Starting settings	Watch out for
Skillet (cast iron or nonstick) + lid	1–2 slices, no oven	Crisp bottom, melted top	Medium heat; preheat about 5 min; a few drops of water beside the slice, lid on (Lodge)	Burning the bottom before the cheese melts
Pizza steel or stone in the oven	3+ slices or a whole pie	Crispest bottom	450°F with the steel in for at least 30 min; slices 4–6 min, whole pie 8–10 min (Baking Steel)	The long preheat
Air fryer	1–2 slices, fast	Crisp bottom; edges can dry	Thin crust 350°F for 3–4 min; thick crust 320°F for 3–5 min; topping-heavy 325°F for 5 min (Cosori)	Small basket, dry rim
Sheet pan in the oven	A whole box, no other gear	Warm but softer	450°F, 10–12 min (Baking Steel)	Pale, soft bottom
Microwave	Speed only	Soft and chewy	Short bursts; stir/rotate, let stand, check 165°F (FoodSafety.gov)	Rubbery crust, uneven hot spots

Why leftover pizza goes soft and leathery

Overnight, moisture from the sauce and cheese moves into the crust, and a closed box adds steam. The crust also stales in the fridge, turning firm even though it isn’t dry. Heat makes it pliable again, and strong heat from below drives the extra moisture out so the bottom can crisp.

It’s the same problem as a soggy pizza middle on a fresh bake: water on top, not enough heat underneath. Reheating works when it fixes the bottom first.

Method 1: Skillet (best for one or two slices)

The pan crisps the bottom by direct contact, and a lid traps a little steam to melt the cheese. Cast-iron maker Lodge recommends this approach for cold slices.

1. Heat the pan. Set a dry skillet over medium heat for about 5 minutes, per Lodge’s cold-slice method.
2. Add the slices flat, with no overlap.
3. Add a little water beside them. Lodge says half a teaspoon, dripped into the pan away from the slice, never on the crust.
4. Cover right away with any lid that fits, or foil.
5. Cook until the bottom is crisp and the cheese has melted. Baking Steel’s skillet guidance is about 3 to 4 minutes covered before you check (Baking Steel reheating guide). Lift an edge with a spatula. If the bottom is browning faster than the top is melting, turn the heat down a notch.

A nonstick skillet works too and is easier to clean if cheese runs. If you already make cast-iron skillet pizza, use that same pan.

Method 2: Oven with a pizza steel or stone (best for a crowd)

For several slices or a whole pie, use the oven, but put the slices straight onto a hot steel or stone, not a cold pan.

1. Preheat. Baking Steel, the maker of the steel linked below, says to heat the oven to 450°F with the steel on the middle rack for at least 30 minutes.
2. Slices go straight on the surface. No tray and no foil. They say foil blocks the heat transfer into the crust, while parchment is fine if you want easy cleanup.
3. Time it. They list 4 to 6 minutes for slices and 8 to 10 minutes for a whole pie. If the crust browns before the cheese melts, they suggest dropping to 400°F for another couple of minutes.
4. Optional: a short broil at the end crisps the top. Stay at the oven.

A stone works the same way; give it at least as long to preheat. See how to use a pizza stone and pizza stone vs pizza steel. To see when the surface (not just the oven air) is ready, an infrared thermometer helps.

No steel or stone? A sheet pan works, but Baking Steel says to expect 10 to 12 minutes at 450°F and a softer bottom. As a kitchen tip, heating the empty pan in the oven first gets you closer to a hot surface.

Method 3: Air fryer (fast and good)

An air fryer blows hot air hard around a small basket, so it crisps the bottom much better than a microwave. The trade-offs are capacity and dry edges. Air-fryer maker Cosori publishes these pizza settings (Cosori reheating guide):

• Thin crust: 350°F for 3–4 minutes
• Thick crust: 320°F for 3–5 minutes
• Topping-heavy: 325°F for 5 minutes, to keep the toppings from burning

Use a single layer with space around each slice. Models differ, so check your manual and look at the first slice a minute early. For deep-dish or Detroit-style leftovers, the lower thick-crust setting gives the center time to heat through.

Method 4: Microwave (when speed wins)

Microwaves heat the water in the food, so the crust steams instead of crisping. If you use one, FoodSafety.gov says to heat microwaved food to 165°F, stir or rotate partway through, and let it stand a few minutes so cooler spots catch up (FoodSafety.gov, 4 Steps to Food Safety). USDA also notes that microwaves have cold spots, so check the temperature in more than one place (USDA FSIS, Leftovers and Food Safety).

Kitchen tip: microwave until hot through, then give the slice a minute or two in a hot, dry skillet to re-crisp the bottom.

Step-by-step: the reheat checklist

1. Pick the method by quantity: 1–2 slices in a skillet or air fryer, more on a steel or stone.
2. Get the surface hot first, so heat goes into the bottom of the slice.
3. In a skillet, add a few drops of water beside the slice and cover it to melt the cheese.
4. Check the underside at the low end of the time range, then add time in short steps.
5. Reheat leftovers to 165°F, checked with a probe food thermometer. An infrared thermometer only reads the surface.

How to store leftover pizza so it reheats well

Good reheating starts the night before. These are the federal guidelines from FoodSafety.gov (Cold Food Storage Chart, 4 Steps to Food Safety, Safe Minimum Internal Temperatures):

• Refrigerate within 2 hours. Make it within 1 hour if the pizza sat somewhere above 90°F, like a hot car or an outdoor party. Don’t leave the box on the counter overnight.
• Fridge at 40°F or below: leftover pizza keeps 3 to 4 days.
• Freezer at 0°F or below: 1 to 2 months for best quality. Frozen food kept continuously at 0°F stays safe indefinitely, but quality drops over time.
• Reheat leftovers to 165°F.
• Use shallow containers so leftovers cool quickly.

For crust quality, get the slices out of the cardboard box, which holds steam against the crust. Wrap them, or stack them in an airtight container with parchment between layers. To freeze, wrap slices individually. Kitchen approach for frozen slices: use the same methods on lower heat for longer, so the center heats before the bottom over-browns, and check the first one. If you’re freezing dough rather than baked pizza, see how to freeze pizza dough balls.

The gear that helps (and what you can skip)

Any heavy skillet with a lid does the job. If you’re choosing gear, these two match the methods above:

• Lodge Pre-Seasoned Cast Iron Skillet, 10.25 inch (affiliate). For the skillet method; a 10.25-inch pan fits one or two slices. No lid included, so use one you have, or foil. Disclosure: as an Amazon Associate, insiderpizza.com earns from qualifying purchases at no extra cost to you.
• Baking Steel Original, 14″ x 16″ (affiliate). For the oven method and for baking fresh pizza. Give it the full preheat. Disclosure: as an Amazon Associate, insiderpizza.com earns from qualifying purchases at no extra cost to you.

Skip special “pizza reheating” gadgets. A basic probe food thermometer is the one extra worth having if you want to confirm 165°F. For clean slices before storing, see pizza cutter types.

Quick answers

What temperature should I reheat pizza in the oven? Baking Steel’s guidance is 450°F on a steel preheated at least 30 minutes. Whatever the oven setting, the slice itself should reach 165°F for leftovers.

Can I eat pizza that sat out overnight? FoodSafety.gov says perishable food shouldn’t sit out more than 2 hours (1 hour above 90°F). An overnight box on the counter is past that.

Bottom line

Reheat from the bottom up: a hot skillet with a lid for one or two slices, a preheated steel or stone for a crowd, the air fryer as the fast backup, and the microwave only when speed is all that matters. Store slices out of the box, eat them within 3 to 4 days, and get them to 165°F.
