Keeping It Fresh: How Long Does Pizza Last In The Fridge?

April 25, 2023


Is it the time of the week when you just want to relax in the comfort of your home and be a couch potato? You open the fridge, see a leftover pizza, and wonder if you can still eat it? Do you need tips on how to reheat your day-old pizza? Look no further! 
Either you found yourself asking for the best way to reheat your pizza, how it can stay fresh, and planning to fridge it for later, this handy guide has you covered. This provides detailed information from tips for safety storage up to the shelf life of your pizza depending on its toppings and type of storing.

Storing pizza can change its nutrition a bit. When you reheat pizza, it might lose some vitamins from veggies but not too much. Also, heating it up in different ways can make small changes in how many calories it has. It’s good to remember that even if leftover pizza is easy and tasty, thinking about its healthiness matters too. Eating healthy is important, and that includes when you’re enjoying pizza from the fridge.
To ensure pizza freshness, proper storage must be of utmost importance. In order for delayed bacterial growth, your fridge temperature must be 3°C (37°F). Additionally, the packaging of your pizza is significant; choosing appropriate materials helps to keep moisture at bay and prevents the pizza from picking up undesirable fridge odors. 

If you happen to leave your pizza overnight on the tabletop, although it is not ideal to waste food, it’s recommended to just throw it away. This might already be contaminated and risk your health safety.

According to USDA guidelines, pizza can generally last for 4 days in your fridge with proper temperature. After this time span, pizza may then develop mold due to bacterial growth risking your health. Generally, pizza spoilage may vary depending on the toppings it has.

Pizzas with meat toppings may be more prone to shorter shelf life as compared to those with vegetables or cheese toppings only. How about the crust? It does matter too as thick pizza baked crust retains more moisture as compared to thinner crusts. Moisture present from pizzas stored in the fridge can rapidly grow colonies of bacteria.

Curious about how long you can leave pizza out before it becomes unsafe to eat? The USDA recommends sticking to the “two-hour rule.” This means you shouldn’t let pizza or takeout sit at room temperature for more than two hours before you should get rid of it. Bacteria love to multiply between 40 to 140 degrees Fahrenheit, so eating food that’s been sitting out can make you sick. Plus, a cardboard pizza box doesn’t provide any insulation, so your pizza is exposed to the elements.

To ensure your pizza remains fresh while stored in the fridge, consider these practices: 

  1. Allow it to cool before refrigerating to minimize crust sogginess.
  2. Store it in an airtight condition to keep moisture and odors out.
  3. Use parchment paper between slices if stacking to prevent sticking.

Once you’ve thawed pizza in the fridge, it’s okay to keep it there for a bit before reheating and eating. But if you warm it up using an oven or microwave, it’s best to eat it soon after without refreezing.

Knowing when to throw out pizza is important for your health. Here are some signs that your pizza has gone bad:

  1. Mold: Any visible green or black spots on the crust or toppings are a clear no-go.
  2. Unusual odors: Immediately throw pizzas with foul odor.
  3. Texture and taste changes: These include, hard-rock crust or slimy toppings.

If any of these signs are present, never hesitate to throw away your pizza immediately as it is most likely spoiled. Spoiled pizzas can be dangerous to eat and may pose illness.

If you want to keep your pizza for longer than a few days, freezing is a good option. Pizza can last for up to 2 months in the freezer when stored properly. Wrap each slice in plastic wrap and then put them in a freezer bag. When you’re ready to eat, thaw the pizza in the fridge for a few hours and then reheat it in the oven for the best texture. Proper storage not only extends the life of your pizza but also helps maintain its flavor and texture, making those leftovers just as enjoyable as when freshly made.

Expiration of leftover pizza is crucial to better enjoy it without sacrificing your safety. USDA released a “4-day rule” for the safe consumption of leftover pizza in the refrigerator. Sealing your leftover pizza into aluminum foil or airtight containers helps keep it fresh.

This will help prevent spoilage and maintain its quality. Don’t forget to let the pizza cool down to room temperature before refrigerating it to avoid condensation and ensure a crispy crust. By following these tips, you can confidently savor your pizza leftovers, knowing they’re both safe and scrumptious.

  1. Can I eat pizza that’s been in the fridge for a week?
  • It’s not advisable. Regular pizza storage is typically up to 4 days. Eating pizza stored longer might result in taste deterioration and potential health risks.
  1. How should I reheat refrigerated pizza to make it taste fresh?
  • For optimal taste, reheat leftover pizza in the oven at 375°F (190°C) until the cheese bubbles. Keep heating time to a maximum of 10 minutes to maintain crust crispiness.
  1. Is it okay to refrigerate pizza in its original box?
  • While convenient, it’s not ideal for freshness. The box allows air and moisture circulation, leading to quicker pizza drying.
