Do you have a packet of grated parmesan cheese that has passed its expiration date? Are you wondering if it’s still safe to consume or if it’s time to throw it out? In this article, we will answer your questions about how long grated parmesan cheese lasts after expiration.

What is Grated Parmesan Cheese?

Grated parmesan cheese, also known as Parmigiano-Reggiano, is a hard, grainy cheese that originated in Italy. It is made from cow’s milk and aged for at least 12 months. Grated parmesan cheese is commonly used as a topping for pasta dishes, soups, and salads.

Expiration Date vs. Best By Date

Before we dive into the shelf life of grated parmesan cheese after expiration, it’s important to understand the difference between the expiration date and the best by date. The expiration date indicates when the food product is no longer safe to consume and should be thrown out. On the other hand, the best by date suggests when the food product will be at its highest quality in terms of flavor and texture.

How Long Does Grated Parmesan Cheese Last After Expiration?

When it comes to grated parmesan cheese, it typically has a shelf life of about six months beyond its printed expiration date in the fridge or freezer.

If you’ve opened your packet of grated parmesan cheese before its printed expiration date, but haven’t finished it yet – don’t worry! Once opened, grated parmesan cheese can last up to six months in the fridge if stored properly in an airtight container or ziplock bag.

If your grated parmesan cheese has a funky smell or texture that wasn’t there before opening – this could indicate that it has gone bad and should no longer be consumed.

Tips for Storing Grated Parmesan Cheese

To prolong the shelf life of your grated parmesan cheese, here are some tips for storing it properly:

  • Store grated parmesan cheese in an airtight container or ziplock bag to prevent moisture and air from getting in.
  • Label the container or bag with the date you opened it to keep track of how long it’s been in the fridge or freezer.
  • Store grated parmesan cheese in the fridge at a temperature between 34°F and 38°F.
  • For even longer storage, freeze grated parmesan cheese for up to eight months. Thaw frozen cheese in the fridge overnight before using.

In Conclusion

In summary, grated parmesan cheese can last up to six months beyond its printed expiration date if stored properly in an airtight container or ziplock bag. Remember that the expiration date indicates when it is no longer safe to consume, while the best by date suggests when it will be at its highest quality. Follow these tips for storing your grated parmesan cheese to ensure it stays fresh and tasty for as long as possible.
