If you’re a fan of Italian cuisine, you know how essential grated Parmesan cheese is for adding flavor to your dishes. However, storing this type of cheese can be a hassle, especially if you buy it in bulk. Here are some tips on how to store grated Parmesan cheese long term.

Understanding Parmesan Cheese

Before we dive into storage techniques, let’s get to know Parmesan cheese better. Grated Parmesan cheese is made from hard Italian cheese, known as Parmigiano-Reggiano. It has a low moisture content, which makes it last longer than other types of cheeses.

How to Store Grated Parmesan Cheese Long Term

  • Refrigerate: Grated Parmesan cheese should be refrigerated immediately after opening the package. Keep it in an airtight container or resealable bag with all the air squeezed out.
  • Freeze: You can also freeze grated Parmesan cheese to make it last even longer.

    Transfer the cheese into a freezer-safe container or bag and make sure all the air is removed before sealing it tightly.

  • Avoid Moisture: Moisture can cause bacteria growth and spoil your grated Parmesan cheese. Therefore, keep it away from moisture by not storing it in the refrigerator door or near any damp areas.
  • Avoid Temperature Fluctuations: Maintaining a consistent temperature is crucial for storing grated Parmesan cheese long term. Avoid exposing it to temperature fluctuations by keeping it away from direct sunlight and heat sources like ovens and stoves.

The Shelf Life of Grated Parmesan Cheese

When stored properly, grated Parmesan cheese can last for a long time. In the refrigerator, it can last up to six months, while frozen Parmesan cheese can last up to eight months. However, keep in mind that the longer you store it, the more its flavor will deteriorate.


Grated Parmesan cheese is a staple ingredient for many Italian dishes and storing it properly is essential for its longevity and flavor. Remember to refrigerate or freeze it immediately after opening the package, keep it away from moisture and temperature fluctuations, and consume it before its shelf life expires.
