About 3 to 4 days. That is how long refrigerated pizza stays safe to eat, assuming it went into the fridge within 2 hours of coming out of the oven.
Leftover pizza is one of the most reheated foods in America, which makes the storage window worth actually knowing instead of eyeballing it.
The toppings matter here — cheese and meat make pizza perishable, so it follows the same rules as other cooked leftovers rather than getting any special treatment for being pizza.
Refrigerated at 40°F or below, pizza keeps for about 3 to 4 days. That applies to most standard toppings — pepperoni, sausage, vegetables, and plain cheese all fall in the same range.
A skillet on medium heat with a lid, or an oven at about 375°F for 8 to 10 minutes, restores a crisp crust better than the microwave. If using a microwave, reheat to at least 165°F internally to be safe.
If you will not finish it in 4 days, freeze slices flat, then bag them once solid — frozen pizza holds good quality for about 1 to 2 months and can go straight from freezer to oven.
Give leftover pizza 3 to 4 days in the fridge, refrigerate it promptly, and reheat to 165°F if you are not sure how fresh it still is.
No — day 5 is past the recommended 3-to-4-day window for refrigerated pizza. Throw it out.
A sealed airtight container or wrap keeps it fresher longer than the original box, which is not designed to seal in the fridge.
Yes — as long as it is within the 3-to-4-day window, cold pizza is safe to eat without reheating.
Baked homemade pizza follows the same 3-to-4-day fridge rule; raw dough is different and typically lasts about 3 days refrigerated or several months frozen.
