So, 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, and 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 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.
REHEAT LEFTOVER PIZZA
While there are a few methods for reheating pizza, I find the oven is too involved for a couple of slices of pizza. The microwave produces a soggy, rubbery mess. Eating the pizza cold is pathetic. I’ve settled on the hands-down best way to heat up a couple of slices is in a skillet—ideally my well-seasoned cast iron skillet, although any non-stick skillet with a lid will do just fine.
This is not difficult as long as you know up front that your most important ingredient here is patience. Just follow these steps precisely and I promise you crisp bottom crust; hot, melted cheese; and no sign whatsoever that it was made the day before.
Step 1: Place one or two slices cold pizza in the cold, dry skillet, crust side down.
Step 2: Put a lid on the skillet
Step 3: Set skillet on a stovetop burner on Medium.
Step 4: Set timer for 8 minutes.
Step 5: Wait. Do not peek or remove that lid for any reason. Just don’t.
That’s it! No need to add water or oil or flip the slices or any other thing you may be wondering about. It’s all about keeping the temperature at medium high and not removing the lid for any reason until it’s done.
NOTE: Because there are several variables here—type of skillet, your burner’s temperature when set to Medium—you may need to adjust these instructions as needed.
REHEAT LEFTOVER FROZEN PIZZA
For frozen leftover pizza, let it thaw on the countertop for at least an hour or defrost in the microwave then follow instructions above.
Reheating pizza properly is all about starting out cold, keeping the temperature at Medium and not removing the lid for any reason until it’s done.
