Pizza lasts 3 to 4 days in the refrigerator when it is stored at or below 40°F (4°C) in an airtight container or wrapped tightly in aluminum foil or plastic wrap. Left open and unwrapped on a shelf, a slice dries out and is best eaten within 1 to 2 days. Cured-meat pizzas such as pepperoni and sausage hold the full 3 to 4 days, while pizzas topped with fresh vegetables, seafood, or fresh mozzarella lean toward the shorter end at 2 to 3 days. Frozen at 0°F, pizza keeps 1 to 2 months for best quality. The tables below give the refrigerator and freezer shelf life by pizza type, the storage methods that stretch it, reheating temperatures and times, and the spoilage signs that mean it is time to throw a slice out.

How Long Does Pizza Last in the Fridge?

Cooked and leftover pizza stays safe and good for 3 to 4 days in the fridge when it is kept at or below 40°F (4°C) — the same window the USDA gives for most leftovers. Store-bought slices may edge slightly past homemade because of preservatives in the dough and cured toppings, but 3 to 4 days is the rule to follow for any pizza. After that the risk of bacterial growth climbs and the pizza should be discarded. Below is the refrigerator shelf life by pizza type.

How Storage Method Changes Shelf Life

How you wrap the pizza matters as much as the toppings. Air is the enemy: it dries the crust and lets the pizza pick up fridge odors. An unwrapped slice sitting open on a shelf is only good for a day or two, while a sealed slice reaches the full 3 to 4 days.

What Affects Pizza's Shelf Life

A pizza's refrigerator shelf life depends mostly on three things: the toppings and cheese, the crust, and how cold and clean the fridge is. Fresh, wet ingredients spoil faster than cured or dried ones.

Toppings and Ingredients

Perishable toppings like fresh vegetables, seafood, and soft cheeses shorten a pizza's life, while cured meats and hard cheeses extend it. Tomato-based sauces generally last longer than creamy or dairy-based sauces. For a topping-specific breakdown, read how long does pepperoni pizza last in the fridge?.

Type of Crust

Crust thickness changes how quickly a slice dries out. Thin-crust pizzas dry out faster, while thick and deep-dish crusts hold moisture and stay pleasant a little longer. If you make your own dough, see Fridge.com guide on refrigerated pizza crust.

Best Way to Store Leftover Pizza

Good storage is what turns "one more day" into three or four. Follow these steps as soon as the pizza has cooled:

1. Cool quickly, store promptly: Let the pizza come down to room temperature so it does not sweat and turn soggy, then refrigerate within two hours of cooking (within one hour if the room is above 90°F).
2. Wrap each slice: Wrap slices tightly in plastic wrap or aluminum foil to keep air out.
3. Seal it up: Place the wrapped slices in an airtight container or a resealable bag with the air squeezed out.
4. Separate stacked slices: Slip a sheet of parchment or wax paper between slices so they do not stick together.
5. Label and date: Mark the container with the date so you know when the 3-to-4-day clock runs out.

Veggie pizzas release water as they sit; blot the slices with a paper towel before wrapping to keep the crust from going soggy. For a full walkthrough, see how to store pizza in the fridge.

Where to Store Pizza in the Fridge

Placement affects how steadily cold the pizza stays:

• Use the middle shelf, where the temperature is most stable.
• Avoid the door — it is the warmest spot and swings in temperature every time the fridge is opened.
• Keep pizza away from raw meat and seafood to prevent cross-contamination; store raw items on the bottom shelf in a tray.
• Hold the fridge at 34 to 40°F (1 to 4°C) and set any humidity control low to discourage sogginess.

Unbaked refrigerated pizza dough keeps for up to 5 days; bake or freeze it before then. For more storage ideas, see leftover pizza in fridge.

How to Reheat Refrigerated Pizza

Reheat leftover pizza to an internal temperature of 165°F (74°C). The method you pick trades speed for crispness:

1. Oven: Preheat to 375°F (190°C) and heat slices on a baking sheet (or straight on the rack for a crisper base) for 10 to 15 minutes, until the cheese bubbles and the crust is crisp.
2. Skillet / stovetop: Warm a non-stick skillet over medium heat, add the slice, cover with a lid, and heat 5 to 8 minutes for a crisp bottom and melted cheese.
3. Toaster oven: Preheat to 375°F (190°C) and heat 8 to 10 minutes.
4. Microwave: Fastest but softest. Set the slice on a paper towel and heat 30 to 60 seconds; placing a microwave-safe cup of water alongside helps keep the crust from turning chewy.

Freezing Pizza to Extend Its Shelf Life

Freezing is the best way to keep pizza beyond a few days. Frozen at 0°F or below — the temperature the USDA recommends for the freezer — pizza keeps 1 to 2 months for best quality and stays safe as long as it remains frozen. Freeze leftover slices within 2 to 3 days of cooking or buying, while they are still fresh.

1. Cool the pizza to room temperature to avoid condensation.
2. Wrap each slice individually in plastic wrap or foil to prevent freezer burn.
3. Flash-freeze the wrapped slices on a baking sheet for about an hour so they do not stick together.
4. Transfer to a freezer bag or airtight container, avoid overcrowding, and label with the date.

Freezer burn — the dry, discolored patches that form when air reaches the food — does not make pizza unsafe, but it dulls flavor and texture, so wrap tightly. For step-by-step help, see how to freeze leftover pizza and how to freeze pizza slices.

Thawing and Reheating Frozen Pizza

Thaw frozen pizza in the refrigerator overnight (about 8 to 12 hours) for the best texture, or reheat it straight from frozen. Thawing at room temperature takes 1 to 2 hours, but do not leave the pizza out longer than that. Once thawed in the fridge, use the pizza within 3 to 4 days and do not refreeze it. Reheat in a 375°F (190°C) oven for 10 to 15 minutes, or microwave for 1 to 2 minutes, until it reaches 165°F.

Signs Pizza Has Gone Bad

Even inside the 3-to-4-day window, check a slice before eating it. Watch for these signs of spoilage:

• Odor: A sour or off smell means bacteria are at work — discard it.
• Mold: Any fuzzy green, white, or black spots on the crust, cheese, or toppings mean the whole slice goes in the trash.
• Discoloration: Unusual colors or a slimy, glossy film point to spoilage.
• Texture: Slimy cheese or an excessively dry, hard crust is a sign to toss it.
• Taste: If a bite tastes off or bitter, stop eating it.

Use this timeline as a guide, and remember the USDA rule: when in doubt, throw it out. Do not taste a slice to decide — harmful bacteria can be present without any change in smell or look.

Creative Ways to Use Leftover Pizza

Before the clock runs out, put extra slices to work in something new:

• Pizza omelette or frittata: Chop the pizza and fold it into beaten eggs.
• Pizza grilled cheese or quesadilla: Layer slices between bread or tortillas and griddle until crisp.
• Waffle-maker pizza: Press a slice in a waffle iron for crispy edges.
• Pizza croutons: Cube and toast leftover crust for salads or tomato soup.
• Refresh it: Add fresh toppings like arugula, tomato, or basil, a drizzle of olive oil, or a shake of red pepper flakes and Parmesan before reheating, and serve with marinara, ranch, or garlic-butter dip.

Frequently Asked Questions

How long is pizza good in the fridge?

Properly stored at or below 40°F (4°C), pizza is good for 3 to 4 days.

Can you eat pizza that has been in the fridge for a week?

No. Pizza should be eaten within 3 to 4 days. A week-old slice is past the safe window and should be discarded, even if it looks fine.

Is 5-day-old pizza safe to eat?

Five days is beyond the recommended 3-to-4-day limit, so the risk of foodborne illness rises. When in doubt, throw it out.

How long does cooked pepperoni or sausage pizza last in the fridge?

Because pepperoni and sausage are cured meats, these pizzas keep the full 3 to 4 days when sealed and refrigerated.

How long does veggie pizza last in the fridge?

Vegetable pizza lasts about 2 to 3 days, since the vegetables release moisture that shortens its life and softens the crust.

Can you leave pizza out overnight?

No. Bacteria multiply quickly at room temperature. Refrigerate pizza within two hours (one hour if the room is above 90°F); pizza left out overnight should be thrown away.

How long does thawed frozen pizza last in the fridge?

Once thawed in the refrigerator, use the pizza within 3 to 4 days and do not refreeze it.

What temperature should the fridge be for storing pizza?

Keep the refrigerator at or below 40°F (4°C); the ideal range is 34 to 40°F (1 to 4°C).
