The shelf life of Parmesan cheese can vary depending on how it is stored and handled. However, when stored properly, Parmesan cheese can last for a long time after opening. In this article, we will discuss how long Parmesan cheese is good for after opening and provide some tips on how to extend its shelf life.

How to Store Parmesan Cheese

Proper storage is key to keeping your Parmesan cheese fresh for as long as possible. Here are some guidelines:

  • Wrap it tightly: After opening the package, wrap the remaining cheese in wax or parchment paper. This will help prevent moisture from getting in and keep the cheese from drying out.
  • Avoid plastic wrap: Plastic wrap can trap moisture and promote mold growth. It’s best to use wax or parchment paper instead.
  • Refrigerate it: Parmesan cheese should be stored in the refrigerator at a temperature between 35°F and 40°F (1.6°C and 4.4°C).

The Shelf Life of Parmesan Cheese

The shelf life of Parmesan cheese depends on various factors, including its age, quality, and storage conditions. Generally, a block of Parmesan cheese can last anywhere from several weeks to several months after opening if stored properly.

Freshly grated Parmesan cheese:

If you have freshly grated Parmesan cheese, it’s best to use it within a week or two for optimal flavor and texture. However, if stored well in an airtight container in the refrigerator, it can still be safe to eat for up to three weeks.

Sliced or shredded Parmesan cheese:

Sliced or shredded Parmesan cheese typically has a longer shelf life compared to freshly grated cheese. When stored properly, it can last for up to six months after opening.

Grated Parmesan cheese in a can:

Grated Parmesan cheese in a can is often shelf-stable and has a longer shelf life compared to other types of Parmesan cheese. It can last for several months or even years if unopened. However, once opened, it should be stored in the refrigerator and used within three to four months.

How to Tell if Parmesan Cheese Has Gone Bad

While properly stored Parmesan cheese can last for a long time, it’s important to know how to identify signs of spoilage. Here are some indicators that your Parmesan cheese may have gone bad:

  • Mold: If you notice mold growth on the surface of the cheese or if it has an off smell, it’s best to discard it.
  • Slimy texture: If the cheese feels slimy or sticky, it may be an indication of spoilage.
  • Bitter taste: A strong bitter taste is another sign that the Parmesan cheese has gone bad.

In Conclusion

Parmesan cheese can last for a considerable amount of time after opening if stored properly. By following the guidelines mentioned above and paying attention to signs of spoilage, you can enjoy your Parmesan cheese for an extended period without compromising its quality or taste.
