In this article, we’ll discuss the factors that affect the shelf life of parmesan cheese, how to store it properly, and how to tell if it’s gone bad.

We’ll also provide some useful tips for using leftover parmesan cheese.

So let’s get started on your journey to keeping your parmesan cheese fresh and delicious!

What is Parmesan Cheese?

Parmesan cheese, also known as Parmigiano Reggiano, is a hard, aged cheese made from cow’s milk. It originated in Italy and is now produced all over the world.

Parmesan cheese has a distinctive flavor that is nutty and slightly sweet. It’s often grated over pasta dishes, salad, and soup. Parmesan cheese can also be sliced and eaten on its own as a snack.

How Long Does Parmesan Cheese Last?

The shelf life of parmesan cheese depends on several factors, including the type of cheese, the storage conditions, and whether it’s been opened or not.

If you purchase a block of parmesan cheese, it can last up to six months in the refrigerator when stored properly. It’s important to keep the cheese in a resealable bag or container to prevent moisture from getting in and causing mold to grow.

Once you’ve grated your parmesan cheese, it will have a shorter shelf life. Grated cheese can last up to four weeks in the refrigerator when stored in an airtight container.

If you don’t think you will be using the cheese within that time, there are steps you can take to make it last longer. One option is to freeze it.

How to Store Parmesan Cheese

Proper storage is crucial to keeping your parmesan cheese fresh. Here are some tips to help you store it properly:

  • Keep it in the refrigerator: Store parmesan cheese in the refrigerator at a temperature between 35-40°F. Be sure to wrap it in plastic wrap or store it in a resealable bag to prevent any moisture from getting in.
  • Don’t freeze the whole block: Freezing a whole block of parmesan cheese can cause the texture to change once it’s thawed. Instead, freeze grated cheese in small portions for later use.
  • Use a resealable bag: If you’re storing grated cheese, consider using a resealable bag to make it easier to store and portion out.
  • Label the container: Be sure to label the container with the date the cheese was opened or grated so that you can keep track of how long it’s been stored.

How to Tell if Parmesan Cheese Has Gone Bad

It’s important to check your parmesan cheese before using it to ensure that it hasn’t gone bad. Here are some signs to look for:

  • Mold: If you see any mold on the cheese, discard it. Mold can cause food poisoning and other health problems.
  • Rancid odor: If the cheese smells sour or rancid, it’s best to discard it. This is a sign that the cheese has gone bad.
  • Appearance: If the cheese has started to turn an unusual color or has developed a slimy texture, it’s best to discard it.

Tips for Using Leftover Parmesan Cheese

If you have leftover parmesan cheese, there are many ways to use it up. Here are some ideas:

  • Make a cheese sauce: Grate parmesan cheese and mix it with butter, milk, and flour to make a delicious cheese sauce for pasta or vegetables.
  • Add it to eggs: Grate parmesan cheese over scrambled eggs for a delicious breakfast.
  • Make a salad: Use parmesan cheese to top a Caesar salad or sprinkle it over mixed greens.
  • Make garlic cheese bread: Mix grated parmesan cheese with butter and garlic powder to make a delicious spread for bread.
  • Use it as a soup garnish: Use a vegetable peeler to slice thin strips of parmesan cheese and use them as a garnish for soup.

Conclusion

In conclusion, parmesan cheese can last up to six months in the refrigerator when stored properly. It’s important to keep it in an airtight container or resealable bag to prevent moisture from getting in.

If you’re not planning on using the cheese within four weeks, consider freezing it to make it last longer. Grated cheese can be frozen in small portions for later use.

When checking your parmesan cheese, watch out for signs of mold, rancid odor, or unusual appearance. If you spot any of these signs, it’s best to discard the cheese.

With these tips and ideas for using leftover parmesan cheese, you can enjoy this tasty cheese in all sorts of dishes without worrying about it going bad. Happy cooking!
