What You'll Learn
Parmesan cheese can be stored in the freezer
When storing Parmesan in the freezer, it is important to wrap the cheese properly to prevent moisture from causing spoilage. Parmesan needs to breathe, so condensation must be avoided. Vacuum-sealed bags or containers with tight lids can be used to store grated or shredded Parmesan in the freezer.
A whole, unopened block of Parmesan cheese can last seven to nine months in the refrigerator, and an unopened chunk may last up to eight months. In comparison, frozen Parmesan can last much longer, although the exact duration depends on various factors such as the quality of the cheese and freezing conditions.
When using frozen Parmesan, it is recommended to let it defrost for a few minutes at room temperature before consumption. For shredded frozen cheese, breaking up any clumps before use is advisable. It is important to note that the quality and flavour of Parmesan are best when it is fresh, but freezing is a viable option to extend its shelf life.
In summary, Parmesan cheese can be successfully stored in the freezer, especially when proper wrapping techniques are employed. Freezing Parmesan is a practical solution to prolong its shelf life, although the optimal flavour and texture may be slightly compromised.

An unopened chunk of Parmesan cheese will typically remain safe to use for about seven to nine months, even if the "sell-by" or "best by" date on the package expires.
Once the package has been opened, its shelf life depends on factors such as how well it is sealed and stored. If you've grated or shredded the Parmesan, it may have a shorter shelf life compared to a block or wheel of Parmesan. To extend the shelf life, keep the opened Parmesan in an airtight container or resealable bag in the refrigerator. A container of grated Parmesan cheese will last about one week in the refrigerator.
To prevent spoilage, wrap the Parmesan cheese as moisture will cause it to go bad. Store Parmesan cheese in the refrigerator at temperatures below 40°F (4°C). Ensure the cheese is well-sealed to prevent it from drying out or absorbing odours from the refrigerator.
If you have an abundance of Parmesan cheese, you can also consider freezing it to extend its shelf life. Parmesan cheese can be stored in the freezer to prolong its shelf life.

Grated Parmesan lasts about a week in the fridge
Parmesan cheese has a long shelf life, especially when stored properly. An unopened package of Parmesan can last several months beyond its expiration date. However, once a package of Parmesan is opened, its shelf life depends on how well it is sealed and stored. Grated Parmesan, in particular, tends to have a shorter shelf life than a block or wheel of Parmesan.
When storing grated Parmesan, it is advisable to use a vacuum-sealed bag or a container with a tight lid. This helps to prevent moisture from causing spoilage and condensation. Additionally, it is important to pay attention to any signs of spoilage, such as mould growth, off odours, or changes in texture. If mould is noticed on the surface of hard cheeses like Parmesan, it is generally safe to cut off the affected portion, and the rest of the cheese should still be usable.
To maintain the freshness of grated Parmesan, it should be stored separately from other strong-smelling food items and away from raw meats to prevent cross-contamination. Proper storage is essential to preserving the quality, flavour, and texture of Parmesan cheese.
