By some miracle, you ended up with more pizza than you could eat—or you intentionally ordered a larger pie just to have leftovers. Great idea, unless those leftovers sit in the fridge until they dry up, curl up and turn downright disgusting. Properly stored, leftover pizza will retain its best quality for 3 to 4 days in the refrigerator or up to 2 months in the freezer.
Store leftover pizza
The best way to store leftover pizza is NOT to leave it in the box and shove the whole thing in the refrigerator. The cardboard and air freely circulating around the slices will dehydrate them in a big hurry.
The best way is to stack and wrap: Place a single layer of slices on a dinner plate, top with a layer of wax, freezer, foil, or parchment paper. Keep stacking, alternating pizza and paper, until all the pizza’s on the plate. Wrap the whole thing tightly up in plastic wrap and place it in the refrigerator. That’s it! It’s not as easy as just throwing the box in the fridge, but you’ll end up with tastier leftover pizza to reheat.
