How Long is Pizza Good for in the Fridge?

As a pizza lover, I often find myself with leftover slices after a night of indulgence. The question that inevitably arises is, “how long is pizza good for in the fridge?” Properly storing and reheating leftover pizza is crucial to maintaining its quality, flavor, and safety for consumption. In this comprehensive guide, I’ll delve into the intricacies of keeping your pizza fresh, from the moment it leaves the oven until it’s time to reheat and savor those delicious leftovers.

Sitting out at Room Temperature

When it comes to how long pizza is good for at room temperature, the United States Department of Agriculture (USDA) has a strict “two-hour rule” for perishable foods. This means that pizza should not be left out at room temperature for more than two hours. This guideline is crucial because the temperature range between 40°F and 140°F (4°C and 60°C) is known as the “danger zone,” where bacteria can rapidly multiply and potentially cause foodborne illnesses.

It’s important to note that leaving pizza in cardboard boxes without proper insulation can accelerate the deterioration process. The cardboard offers minimal protection against temperature fluctuations, potentially allowing the pizza to enter the danger zone faster. To prevent bacterial contamination and ensure food safety, it’s best to promptly refrigerate any leftover pizza after the initial two-hour window.

In the Fridge

According to the USDA guidelines, pizza can stay fresh in the refrigerator for up to four days. However, proper storage is key to maintaining its quality during this time. To maximize freshness, tightly wrap any leftover slices in foil or plastic wrap, or store them in an airtight container. This helps prevent the pizza from drying out and absorbing unpleasant odors from other foods in the fridge.

Refrigeration effectively slows down the growth of bacteria and other microorganisms, helping to preserve the pizza’s flavor and texture. Remember, the colder the temperature, the slower the bacterial growth, extending the safe consumption window of your leftover pizza.

In the Freezer

If you’re planning to store pizza for longer periods, freezing is an excellent option. When properly wrapped and stored in the freezer, pizza can maintain its quality for one to two months. To ensure optimal preservation, tightly wrap the pizza in foil or plastic wrap, or store it in an airtight, freezer-safe container. This will prevent freezer burn and minimize moisture loss, which can affect the pizza’s texture and flavor.

It’s important to note that while freezing can extend the pizza’s shelf life, it may result in slight changes to its taste and texture over time. As the storage period increases, the pizza may become drier or develop an off-flavor. Therefore, it’s best to consume frozen pizza within a reasonable timeframe to avoid significant deterioration.

Before consuming any leftover pizza, always inspect it for abnormal colors or odors, which could indicate spoilage. If the pizza appears or smells questionable, it’s better to err on the side of caution and discard it to prevent potential foodborne illnesses.

How to Reheat Pizza

Reheating leftover pizza is an art form in itself, and choosing the right method can make all the difference in achieving that fresh-out-of-the-oven taste and texture. Various reheating methods are available, including the oven, frying pan, air fryer, and microwave. The choice ultimately depends on your available equipment and desired results.

Reheating Methods

In an Oven

Reheating pizza in an oven is a popular and effective method. It can be done using a conventional oven, convection oven, or even a toaster oven. Here are the steps to follow:

  1. Preheat your oven to 400°F (200°C). This high temperature ensures that the pizza crust gets crispy while the toppings heat through evenly.
  2. Place the pizza slices on a baking sheet or directly on the oven rack. If using a baking sheet, consider lining it with parchment paper or foil for easy cleanup.
  3. Reheat the pizza for 8 to 10 minutes, or until the crust is crispy and the toppings are heated through.
  4. Monitor the pizza closely to prevent burning or overheating.

Preheating the oven is crucial to achieve a crispy crust and evenly heated toppings. If you’re using a convection oven, you may need to adjust the temperature and cooking time slightly, as convection ovens tend to cook faster and more evenly.

In a Frying Pan

If you don’t have access to an oven, a frying pan can be an excellent alternative for reheating pizza. Follow these steps:

  1. Choose a nonstick skillet and place it over medium heat.
  2. Add a small amount of water to the pan, about 2-3 tablespoons.
  3. Place the pizza slices in the pan and cover with a lid.
  4. Heat the pizza for 3 to 5 minutes, or until the crust is crispy and the toppings are heated through.

The water in the pan creates steam, which helps to reheat the pizza evenly without drying out the crust or toppings. Be careful when removing the lid, as the steam can be hot.

In an Air Fryer

Air fryers have gained immense popularity in recent years, and they can be an excellent tool for reheating pizza. Here’s how to do it:

  1. Preheat your air fryer to 350°F (175°C).
  2. Place the pizza slices in the air fryer basket, being careful not to overcrowd it.
  3. Air fry the pizza for 3 to 5 minutes, or until the crust is crispy and the toppings are heated through.
  4. Check the pizza frequently to prevent burning or overheating.

Air fryers work by circulating hot air around the food, creating a crispy texture while reheating evenly. This method is particularly useful for achieving a crispy crust without the need for additional oil or butter.

In a Microwave

While the microwave may not be the ideal method for reheating pizza, it can be a convenient option when you’re short on time. Here are some tips for microwave reheating:

  1. Place the pizza slices on a microwave-safe plate or container.
  2. Add a microwave-safe mug or ramekin filled with water next to the pizza. This helps to create steam, preventing the crust from becoming chewy or dry.
  3. Microwave the pizza for 30 seconds to 1 minute, depending on the number of slices and your microwave’s power.
  4. Check the pizza and continue microwaving in 30-second intervals until the desired temperature is reached.

Keep in mind that microwave reheating can sometimes result in a soggy crust or unevenly heated toppings. To mitigate this, you may want to consider briefly crisping up the crust in a hot skillet or under the broiler after microwaving.


In summary, properly storing and reheating leftover pizza is essential for maintaining its quality and safety. By following the guidelines outlined in this article, you can enjoy your pizza leftovers for up to four days in the fridge or up to two months in the freezer. Whether you prefer the oven, frying pan, air fryer, or microwave, selecting the right reheating method can help you achieve that fresh-out-of-the-oven taste and texture.

Remember, when it comes to how long pizza is good for in the fridge, the key is to store it properly and consume it within a reasonable timeframe. With these tips in hand, you can savor every last slice of your favorite pizza without compromising on flavor or risking foodborne illnesses. Bon appétit!
