The best way to reheat pizza in a toaster oven is to use moderate heat until the crust crisps and the cheese is hot. For most leftover slices, start around 350 degrees F on a small tray or rack. Thin slices may take only a few minutes, while thick crust or heavily topped pizza may need longer.
Quick Method
- Preheat the toaster oven to about 350 degrees F.
- Place the slice on a tray, small pan, or toaster-oven rack.
- Heat for about 4 to 8 minutes, checking early for thin crust.
- Remove when the cheese is hot and the crust is crisp.
- Let the slice sit for a minute before eating so the cheese does not burn your mouth.
Toaster Oven Settings
| Pizza type | Good starting setting | What to watch |
|---|---|---|
| Thin crust | 325 to 350 degrees F | Edges can brown quickly |
| Regular slice | 350 degrees F | Cheese should bubble and crust should firm up |
| Thick crust or deep dish | 325 to 350 degrees F, longer time | Center needs time to heat before crust over-browns |
| Very cheesy slice | Tray or foil-lined pan | Cheese can drip onto the heating elements |
Food Safety Notes
Only reheat pizza that was stored safely. Perishable leftovers should not sit in the temperature danger zone for too long, and refrigerated leftovers are best used within a few days. If the pizza has meat, seafood, or other perishable toppings, heat it thoroughly. Use a food thermometer when safety matters more than texture.
FAQ
What temperature should I use to reheat pizza in a toaster oven?
Start around 350 degrees F. Use a little lower heat for thick slices so the center warms before the crust over-browns.
How long does pizza take in a toaster oven?
Most slices take about 4 to 8 minutes, depending on thickness, toppings, and whether the toaster oven was preheated.
Should I use foil?
Foil can make cleanup easier, especially for very cheesy slices. Keep foil away from heating elements and follow your toaster oven manual.
How do I keep the crust crisp?
Use a rack or preheated tray and avoid covering the slice. Covering traps steam and softens the crust.
Can I reheat pizza that sat out overnight?
No. Reheating does not reliably make mishandled leftovers safe. Discard pizza that was left out too long.
