Pizza is one of the most popular foods in the world, and it’s not uncommon for people to order a pie or make one at home, only to have leftovers that need to be stored. But how long does pizza last when it’s not refrigerated? The answer to this question depends on several factors, including the type of pizza, the storage conditions, and personal tolerance for food safety.
Factors Affecting the Shelf Life of Pizza
When it comes to determining how long pizza lasts unrefrigerated, there are several factors to consider. These include:
Type of Pizza
Different types of pizza have varying shelf lives. For example:
- Cheese pizza: This type of pizza tends to last longer than others because it doesn’t contain meat or vegetables, which can spoil quickly.
- Meat lovers pizza: Pizzas with meat toppings like pepperoni, sausage, and bacon have a shorter shelf life due to the risk of bacterial growth.
- Veggie pizza: Pizzas with vegetable toppings like mushrooms, onions, and bell peppers can last longer than meat-topped pizzas, but still pose a risk of spoilage.
Storage Conditions
The way you store your pizza can greatly affect its shelf life. Here are some factors to consider:
- Temperature: Pizza should be stored in a cool, dry place, away from direct sunlight and heat sources. A temperature range of 40°F to 70°F (4°C to 21°C) is ideal.
- Humidity: High humidity can cause pizza to become soggy and develop off-flavors. Store your pizza in a dry environment to prevent this.
- Light: Direct sunlight can cause pizza to become stale and develop off-flavors. Store your pizza in a dark or shaded area.
Personal Tolerance for Food Safety
Ultimately, the shelf life of pizza depends on your personal tolerance for food safety. If you’re concerned about the risk of foodborne illness, it’s best to err on the side of caution and discard your pizza after a few hours.

How long does pizza last unrefrigerated?
Pizza can last unrefrigerated for several hours, but its shelf life largely depends on the storage conditions and the type of pizza. Generally, a pizza can be safely stored at room temperature for 2-4 hours. However, if the room temperature is above 90°F (32°C), it’s recommended to discard the pizza after 1 hour.
It’s essential to note that even if the pizza is within its safe storage time, its quality may degrade over time. The crust may become soggy, and the toppings may lose their flavor and texture. If you’re unsure whether the pizza is still safe to eat, it’s always best to err on the side of caution and discard it.
What factors affect the shelf life of pizza?
Several factors can affect the shelf life of pizza, including the type of crust, toppings, and storage conditions. A pizza with a thick crust and minimal toppings may last longer than a pizza with a thin crust and high-moisture toppings. Additionally, pizzas stored in a cool, dry place will generally last longer than those stored in a warm, humid environment.
The handling and preparation of the pizza can also impact its shelf life. Pizzas that are handled roughly or exposed to contaminants may spoil faster than those that are handled carefully and stored properly. Furthermore, pizzas that are cooked to an internal temperature of at least 165°F (74°C) will generally last longer than those that are undercooked.
Can I store pizza at room temperature overnight?
It’s not recommended to store pizza at room temperature overnight. While a pizza may be safe to eat after several hours at room temperature, storing it overnight can increase the risk of bacterial growth and foodborne illness. Bacteria like Staphylococcus aureus, Salmonella, and E. coli can multiply rapidly on perishable foods like pizza, especially in warm temperatures.
If you need to store pizza overnight, it’s best to refrigerate it at a temperature of 40°F (4°C) or below. This will slow down bacterial growth and help keep the pizza fresh for a longer period. When refrigerating pizza, make sure to store it in a covered container to prevent moisture and other contaminants from affecting its quality.
How do I store pizza to extend its shelf life?
To extend the shelf life of pizza, it’s essential to store it properly. If you plan to store pizza for a short period, you can keep it at room temperature in a cool, dry place. However, if you need to store it for an extended period, refrigeration is the best option. When refrigerating pizza, make sure to store it in a covered container to prevent moisture and other contaminants from affecting its quality.
When storing pizza, it’s also essential to keep it away from strong-smelling foods, as the pizza can absorb odors easily. Additionally, you can freeze pizza to extend its shelf life. Frozen pizza can be stored for up to 3-4 months. When freezing pizza, make sure to wrap it tightly in plastic wrap or aluminum foil to prevent freezer burn.
Can I freeze pizza to extend its shelf life?
Yes, you can freeze pizza to extend its shelf life. Freezing pizza can help preserve its quality and prevent bacterial growth. When freezing pizza, make sure to wrap it tightly in plastic wrap or aluminum foil to prevent freezer burn. Frozen pizza can be stored for up to 3-4 months.
When freezing pizza, it’s essential to note that the quality may degrade over time. The crust may become soggy, and the toppings may lose their flavor and texture. However, freezing is a great way to extend the shelf life of pizza, especially if you don’t plan to consume it within a few days.
How do I reheat frozen pizza?
Reheating frozen pizza is a straightforward process. You can reheat it in the oven, microwave, or on the stovetop. When reheating frozen pizza, make sure to follow the recommended cooking instructions to ensure food safety. The internal temperature of the pizza should reach at least 165°F (74°C) to prevent foodborne illness.
When reheating frozen pizza, you can also add some extra toppings or seasonings to enhance its flavor. However, make sure to handle the pizza safely and avoid cross-contamination with other foods. Additionally, if you’re reheating a frozen pizza that’s been stored for an extended period, it’s essential to check its quality before consumption. If the pizza has an off smell or slimy texture, it’s best to discard it.
What are the signs of spoiled pizza?
Spoiled pizza can exhibit several signs, including an off smell, slimy texture, and mold growth. If the pizza has an unusual or sour smell, it’s likely spoiled. Additionally, if the crust is soggy or the toppings are slimy, it’s best to discard the pizza.
Mold growth is another sign of spoiled pizza. Check the pizza for any visible signs of mold, especially in the crevices and corners. If you notice any mold, it’s essential to discard the pizza immediately. Furthermore, if you’re unsure whether the pizza is still safe to eat, it’s always best to err on the side of caution and discard it.
