The shelf life of leftover pizza depends on a variety of different factors, including the sell-by date, preparation and storage method. 

How long it lasts depends on its original state. For example, you may have ordered from Domino’s or another favorite pizza place and taken it home to freeze, or you may have bought it from the store already frozen.

This has an effect on how long your frozen pizza will last. Typically, takeout pizza or homemade pizza can last between 4-6 months, whereas store-bought frozen pizza could potentially last between 12-18 months. 

Even after then, it is likely that it will still remain safe for consumption. One thing to note, however, is that best by dates are usually guidance for the taste and freshness of the product. If it is stored in the freezer for longer, over time, the food quality may deteriorate.

How to Know if Frozen Pizza has Gone Bad?

These are things that you should look out for to detect if your frozen pizza has gone bad:

Freezer Burn

Freezer burn shows up on your food when it has dried out. This can occur from incorrect storage or from being in the freezer for a long period of time. Ice crystals can formulate on the outside and dry spots or discoloration may appear on your pizza.

In some cases, freezer burn can also appear as dark, leathery patches.

You CAN still eat the pizza as it is safe to do so, but it may have an impact on the quality of the product, regarding taste and texture, so it’s really up to you on this one.

What Happens if You Eat Frozen Pizza After It Has Spoiled?

Due to the fact that frozen foods are often safe to eat even after their expiration date, it is highly unlikely that you will get sick or have any effects if you eat frozen pizza after its best by date. 

Sometimes it’s better to be safe than sorry. You can see the symptoms of food poisoning on the CDC website to give you that peace of mind. 

How to Store Frozen Pizza Correctly?


According to the U.S. Food and Drug Administration (FDA), if frozen food is consistently kept at 0 degrees Fahrenheit, it should last indefinitely if the packaging has not been opened or damaged. So, the temperature is a massive factor in how your frozen pizza should be stored.

Whilst freezing food does not kill off bacteria, it stops it from growing whilst stored at the correct temperature and therefore minimizes any risk of food poisoning or illness.

If the frozen pizza is left out in temperatures above 40 degrees Fahrenheit for two hours or more, you should discard it, just to be safe. 

To ensure that your freezer is at the right temperature, you can buy thermometers to put into your freezer and regularly check it. You should do this at least once a week. By taking these precautions, you are ensuring that your frozen foods last for longer. 


If you have bought an already frozen pizza from the store, chances are that it is already packaged correctly and you wouldn’t have to do anything with this.

However, if you have homemade pizza or leftovers from takeout, you should think about extra measures to put in place to ensure that you are correctly storing it. 

You should place your pizza into a freezer-safe airtight container. This ensures that there’s little room for bacteria to accumulate when opening and closing your freezer, as well as being a good way to prevent freezer burn.

Final Thoughts

Whether or not frozen pizza goes bad can be a little tricky to give a straightforward answer. Frozen pizza does technically expire. After being stored for a long period of time, frozen pizza will eventually lose its original yummy taste and the texture may become a little spongier. 

Ideally, that’s not what you really want! So, to ensure that you can still reap the delicious benefits of your pizza, aim to consume within 12-18 months.
