How Long Does Leftover Pizza Last?
Leftover pizza from delivery, takeout, homemade, or frozen pizza that has been cooked.
The Short Answer

Reheat leftover pizza in a skillet on medium heat with a lid on. The bottom gets crispy while the steam melts the cheese. Microwave pizza is a crime against food science.
How to Store Leftover Pizza
Stack slices with parchment paper between them in an airtight container. Do not leave the pizza box in the fridge; it dries out the pizza.
How to Tell if Leftover Pizza Has Gone Bad
Look for these signs that leftover pizza has spoiled: hardened, dried-out texture, mold spots, off smell.
The Professor's rule: When in doubt, throw it out. No meal is worth food poisoning.
The Bottom Line
Properly stored leftover pizza stays safe for 3–4 days in the fridge. Always store in airtight containers, refrigerate within 2 hours of purchase or preparation, and trust your senses. If something looks, smells, or feels off, discard it regardless of how many days it has been. Freezing is always an option if you will not use it within the refrigerator window.
