How Long Does Parmesan Cheese Keep?

When it comes to Parmesan cheese, many people wonder how long it can be kept before it goes bad. Whether you use it as a topping for pasta, a key ingredient in a sauce, or simply enjoy it on its own, knowing how to properly store and extend the shelf life of Parmesan cheese is important.

Storage Tips for Parmesan Cheese

1. Refrigeration is Key

Parmesan cheese should always be stored in the refrigerator.

The cold temperature helps slow down the growth of bacteria and keeps the cheese fresh for longer. Wrap the cheese tightly in plastic wrap or place it in an airtight container before refrigerating.

2. Avoid Freezer Storage

While some cheeses can be stored in the freezer, Parmesan cheese doesn’t fare well in extremely low temperatures.

Freezing can alter its texture and affect its flavor. It’s best to avoid freezing Parmesan cheese if possible.

Shelf Life of Parmesan Cheese

Freshly Grated Parmesan Cheese:

  • Freshly grated Parmesan cheese has a shorter shelf life compared to whole blocks or wedges of cheese.
  • If stored properly in the refrigerator, it can last for about 1 to 2 weeks.
  • To keep it fresh for longer, store grated Parmesan cheese in an airtight container or resealable bag with excess air removed.

Whole Blocks or Wedges of Parmesan Cheese:

  • Whole blocks or wedges of Parmesan cheese have a longer shelf life compared to grated cheese.
  • If stored properly in the refrigerator, they can last for about 3 to 4 weeks.
  • Ensure that the cheese is wrapped tightly in plastic wrap or stored in an airtight container to prevent moisture and odors from affecting its quality.

Signs of Spoiled Parmesan Cheese

1. Mold Growth:

If you notice mold on your Parmesan cheese, it’s an indication that it has gone bad. Mold can affect the taste and texture of the cheese, making it unsafe to consume.

2. Off Odor:

A strong, unpleasant odor is another sign that your Parmesan cheese has spoiled. Trust your senses – if it doesn’t smell right, it’s best to discard it.

Conclusion

In conclusion, Parmesan cheese can be kept for different durations depending on whether it’s freshly grated or in whole block form. When properly stored in the refrigerator, grated Parmesan can last for about 1 to 2 weeks, while whole blocks or wedges can last for approximately 3 to 4 weeks.

It’s important to be aware of signs of spoilage such as mold growth and off odors. By following these storage tips and keeping an eye out for spoilage indicators, you can enjoy your Parmesan cheese at its best for a longer period!
