Yes, if it thawed in the fridge. The USDA says food thawed in the refrigerator can be safely refrozen, although it may lose some quality. With pizza, that usually means a soggier crust and wetter toppings.
Don’t refreeze a pizza that sat out at room temperature for more than 2 hours (1 hour above 90°F), such as one left in a car or on the counter. Cook it right away if it’s still within that window, or throw it out.
Quick guide
| Pizza | Refreeze? |
|---|---|
| Store-bought frozen pizza, thawed in the fridge | Yes. Or simply cook it now |
| Thawed on the counter, under 2 hours | Better to cook it now than refreeze it |
| Out more than 2 hours | No. Throw it out |
| Leftover cooked pizza | Freeze it within 3 to 4 days. It keeps 1 to 2 months frozen |
Tips for better results
- The best option is to cook it, then freeze the leftover slices. Cooked pizza freezes better than thawed raw pizza.
- Wrap it tightly in plastic wrap and foil, so ice crystals don’t form on the toppings.
- Bake it from frozen on a hot tray or pizza stone, so the crust crisps instead of steaming.
