How Long Does Parmesan Cheese Last? Does it Go Bad?

It’s hard to deny the superiority of well-aged Parmesan cheese.

With its nutty flavor, pronounced saltiness, and crunchy texture, it adds a special something to any Italian dish.

But have you ever wondered how long your hunk of parmesan will last in the refrigerator?

Does it go bad like other types of dairy products?

As much as we love the delicious taste of genuine Parmigiano Reggiano or Grana Padano, making sure these expensive cheeses will stay edible is paramount – after all, you don’t want spoiled cheese ruining an otherwise tasty meal!

But how do you know when your parm has gone bad?

Read on to learn what kind of shelf life grated or block Parmesan really has and discover tips for prolonging its freshness.

What’s Parmesan Cheese?

Parmesan cheese is a type of hard, aged cheese that originates from Italy.

The cheese is made exclusively with raw cow’s milk, and certain breeds of cows must be used in the production process to get the desired flavor.

Parmesan has a rich taste and a somewhat crumbly texture, making it an ideal grating or shaving cheese.

It pairs well with different dishes and can also be enjoyed all on its own.

Parmesan boasts many vitamins, minerals and other nutrients making it perfect for those looking to add something nutritious to their diet.

How to Store Parmesan Cheese?

Storing parmesan cheese properly is an essential step in preserving its intense flavor and signature nuttiness.

Because it is such a hard cheese compared to other cheeses, it can last for much longer as long as you protect it from humidity.

To store Parmesan cheese for extended periods of time, wrap it in wax paper or parchment before placing in a plastic bag and storing in the warmest part of the refrigerator.

Make sure to let the extra air out of the bag before sealing and squeeze out any remaining moisture that might be present on the block of cheese itself.

Finally, replace the wrapping every 3-4 weeks to prevent excess moisture from developing around the edges which could cause molding over time.

With these few simple steps you can enjoy your favorite parmesan cheese for months to come.

How Long Does Parmesan Cheese Last?

As it ages, Parmesan cheese gets saltier and deeper in flavor.

Its long shelf life marks Parmesan as one of the few cheeses that do not require refrigeration.

Depending on how it is stored, Parmesan can stay good for two to three months after opening the package.

It can last up to eight months if sealed properly and refrigerated.

To extend its life even further, it can be grated or sliced into smaller pieces and frozen for several months without losing its texture or flavor.

Thus, with simple storage techniques like buying whole blocks instead of pre-grated portions and wrapping the cheese heavily in plastic wrap before refrigerating it, consumers can enjoy this delicious Italian delicacy for a longer period of time.

Can You Freeze Parmesan Cheese?

Parmesan cheese can be frozen, but it’s important to do so properly in order to maintain the quality of the cheese.

When freezing Parmesan cheese, wrap it tightly in plastic wrap or aluminum foil and place it in the freezer.

It’s also a good idea to write the date on the cheese so you know how long it has been frozen.

Parmesan cheese will last for several months when properly stored in the freezer, but it may start to lose some of its flavor after that point.

When thawing Parmesan cheese, be sure to do so slowly in the refrigerator.

Never thaw Parmesan cheese at room temperature, as this can cause bacteria to grow.

If you’re not planning on using your Parmesan cheese within a few months, it’s best to keep it grated and stored in an airtight container in the fridge.

This will help keep the flavor of the cheese fresh for longer.

How to Tell If Parmesan Cheese is Bad?

Parmesan cheese is a hard, dry cheese that is made from cow’s milk.

It has a sharp, nutty flavor and can be used in a variety of dishes.

Parmesan cheese can last for several months if it is stored properly.

However, like all cheeses, it can eventually go bad.

There are a few things you can look for to tell if Parmesan cheese has gone bad.

First, check the color of the cheese. If it has started to turn yellow or brown, then it has probably gone bad.

Second, smell the cheese. If it has a sour or ammonia-like smell, then it has probably gone bad.

Third, taste the cheese. If it tastes sour or bitter, then it has probably gone bad.

If you’re not sure whether or not the Parmesan cheese is still good, err on the side of caution and throw it out.

It’s better to be safe than sorry when it comes to food poisoning.


Parmesan cheese can last for a long time if stored properly.

However, it can go bad if not stored properly.

How long Parmesan cheese lasts depends on a number of factors, such as how it is stored, the type of cheese, and whether it has been opened or not.

Parmesan cheese can be stored in the refrigerator or freezer, but it should be wrapped tightly to prevent it from drying out.
