Leftover pizza is good for 3 to 4 days in the refrigerator at 40°F (4°C) or below. That’s the USDA guideline for both delivery and homemade pizza. Get it into the fridge within 2 hours of delivery or baking, or within 1 hour if it’s hotter than 90°F (32°C). In the freezer, leftover pizza keeps its best quality for 1 to 2 months, and it stays safe for as long as it stays frozen at 0°F (-18°C).
Below you’ll find the storage times in one table, what to do about pizza that sat out overnight, how to store and freeze slices, and how to reheat them safely.
Leftover Pizza Storage Times at a Glance
| Where | How long | What the time means |
|---|---|---|
| Room temperature | 2 hours at most (1 hour above 90°F / 32°C) | Safety limit; throw it out after that |
| Refrigerator, 40°F (4°C) or below | 3 to 4 days | Safety limit |
| Freezer, 0°F (-18°C) or below | 1 to 2 months | Best quality; safe indefinitely while frozen |
| Store-bought frozen pizza, kept frozen | 12 months | Best quality; cook as the package directs |

How Long Is Leftover Pizza Good for in the Fridge?
Leftover pizza is good for 3 to 4 days in the refrigerator. FoodSafety.gov’s cold storage chart, the FSIS guide to take-out foods and the USDA FoodKeeper all give the same range, so there’s no conflict to sort out here.
The 3-to-4-day window assumes two things: the pizza went into the fridge within 2 hours, and your refrigerator stays at 40°F (4°C) or below. If either of those didn’t happen, the window doesn’t apply.
USDA gives one time for pizza leftovers. It doesn’t set separate times for delivery, takeout, frozen-then-baked or homemade pizza, or for different toppings, so the same 3 to 4 days applies to all of them.
Is leftover pizza good after 5 days?
We don’t recommend eating it. Five days is past the 3-to-4-day USDA guideline for leftover pizza. If you know you won’t finish the pizza within that window, freeze the extra slices on day 1 or 2 instead of waiting.
Can Pizza Sit Out Overnight?
No. Pizza that sat out overnight should be thrown away, even if it looks and smells fine.
FSIS advises discarding perishable foods left at room temperature longer than 2 hours, or longer than 1 hour when the temperature is above 90°F (32°C). FSIS’s take-out food guidance lists pizza among the leftovers to refrigerate, and it applies the same 2-hour limit to delivered and take-out food.
The reason is temperature. According to FoodSafety.gov, the bacteria that cause food poisoning multiply quickest between 40°F (4°C) and 140°F (60°C). A kitchen counter sits squarely in that range.
Does leftover pizza need to be refrigerated?
Yes. FSIS says to refrigerate take-out and delivered food as soon as possible, always within 2 hours after purchase or delivery, or within 1 hour if the air temperature is above 90°F (32°C).
For delivery and takeout, that clock starts when the pizza arrives or when you pick it up, not when you finish eating. Time spent in a hot car on the way home counts too. If the box sat open on the table through a long evening, it’s safer to throw out what’s left.
How to Store Leftover Pizza
Good storage keeps pizza safe for its full 3 to 4 days and helps it taste better when you reheat it.
Take it out of the box
FSIS recommends covering leftovers, wrapping them in airtight packaging or sealing them in storage containers. That keeps bacteria out, holds in moisture and stops leftovers from picking up odors from other food. A cardboard pizza box isn’t airtight, so move the slices to a sealed container, a zip-top bag, or wrap them in plastic wrap or foil.
Chill it quickly
Put the pizza in the fridge as soon as the meal is over, within the 2-hour limit. Spreading slices out in a shallow container, rather than stacking a whole pie in a deep one, helps them cool faster. FSIS recommends shallow containers for quick cooling.
Check your fridge temperature and date the container
Keep your refrigerator at 40°F (4°C) or below. The U.S. Food and Drug Administration (FDA) notes that appliance thermometers are the best way to know your fridge and freezer temperatures, and they’re generally inexpensive. A strip of tape with the date on the container makes the 3-to-4-day rule easy to follow.
Can You Freeze Leftover Pizza?
Yes. Leftover pizza freezes well, and freezing is the best option for any slices you won’t eat within 3 to 4 days.
How long does frozen leftover pizza last?
FoodSafety.gov and FSIS list 1 to 2 months in the freezer for leftover pizza. That time is about quality, not safety. Pizza kept frozen continuously at 0°F (-18°C) or below stays safe indefinitely, but the crust and toppings slowly dry out and lose flavor. Freezing sooner gives you better results than freezing on day 4.
Store-bought frozen pizza that has never been thawed is a separate item. The USDA FoodKeeper lists 12 months in the freezer for best quality and says to keep it frozen and cook it as directed.
How to freeze leftover pizza
- Freeze it early. Freeze slices on the day you got the pizza or the day after, not at the end of the fridge window.
- Portion it. Freeze single slices or meal-size stacks so you only thaw what you’ll eat.
- Wrap it airtight. Wrap each slice or stack in plastic wrap or foil, then put it in a freezer bag or sealed container with as much air pressed out as possible.
- Label it. Write the date on the bag so you can use it within the 1-to-2-month quality window.
How to thaw frozen pizza
You can thaw leftover pizza in the refrigerator, which is FSIS’s safest thawing method. FSIS also says frozen leftovers such as casseroles and combination meals can be reheated in the oven or microwave without thawing first. Either way, reheat the slices until they reach 165°F (74°C).
According to FSIS, leftovers thawed in the refrigerator can go back in the freezer without being reheated. Pizza thawed in the microwave should be heated to 165°F (74°C) before it’s refrozen.
How to Reheat Leftover Pizza Safely
FSIS recommends reheating leftovers until they reach 165°F (74°C), measured with a food thermometer. Check the thickest part of the slice, where the toppings are piled highest.
- In the microwave: Cover the pizza and rotate it for even heating, then let it rest briefly before you check the temperature, as FSIS advises.
- In the oven or a skillet: These methods keep the crust crisper. Heat until the cheese is bubbling and the center reaches 165°F (74°C).
- From the freezer: Allow extra time and check the temperature in more than one spot.
Reheating doesn’t reset the clock. Pizza that’s past 3 to 4 days in the fridge, or that sat out longer than 2 hours, should be thrown away rather than reheated.
How to Tell If Leftover Pizza Has Gone Bad
Storage time and temperature are the most reliable guides. Throw leftover pizza away once it’s been in the fridge longer than 3 to 4 days, or if it sat out longer than 2 hours (1 hour above 90°F / 32°C), even if it looks and smells fine.
The FDA warns that food can make you very sick even when it doesn’t look, smell or taste spoiled. FSIS explains that the bacteria that cause foodborne illness are different from the spoilage bacteria that cause off odors and textures.
Mold, a sour smell or slimy toppings are reasons to throw pizza out right away. But the absence of those signs doesn’t mean pizza is safe, and you should never taste a questionable slice to decide. When in doubt, throw it out.
Make Leftover Pizza Go Further
Pizza night often leaves a few extra slices. A little planning keeps them from going to waste:
- Decide on day 1. Set aside what you’ll eat in the next 3 days and freeze the rest right away.
- Freeze lunch portions. Two wrapped slices in a labeled bag make an easy lunch for a busy day.
- Keep them visible. Store slices at eye level so they don’t get lost behind newer groceries.

Frequently Asked Questions
Does homemade pizza last longer than delivery pizza?
No. USDA lists one storage time for leftover pizza: 3 to 4 days in the refrigerator and 1 to 2 months in the freezer for best quality. That applies to homemade, delivery and takeout pizza alike.
How long can you keep leftover pizza in the fridge if it has meat toppings?
The same 3 to 4 days. USDA’s pizza guideline doesn’t change by topping, and cooked meat and poultry leftovers carry the same 3-to-4-day refrigerator time on their own.
