Parmesan is a classic type of hard Italian cheese with a richly complex, nutty flavor. Since it usually gets sold in large blocks, it’s essential to know how to properly store it and how long its shelf life is. In this article, learn the answer to, “How long is parmesan cheese good for?”
In general, hard cheeses like cheddar and parmesan have a much longer shelf life than soft cheeses like Brie or cream cheese. Hard cheeses have a significantly lower moisture content, which helps forestall the growth of harmful bacteria and mold.
However, like all dairy products, parmesan cheese is perishable and does eventually go bad. The exact shelf life of parmesan cheese depends on whether or not the package is open, what sort of packaging you’re using, and if the cheese sits out at room temperature for a long time.
Read on to discover exactly how to tell when parmesan cheese is gone bad and how to keep your delicious cheese fresh for as long as possible.
Does Parmesan Cheese Go Bad?
If you’ve had a block of parm in your fridge for several weeks, you may start asking, “Does parmesan cheese go bad?” The short answer is yes. But not for quite some time.
Under optimal storage conditions, an unopened package of parmesan cheese lasts up to four months. After opening, try to use it within the next six to eight weeks.
Although the names sometimes get used interchangeably, parmesan cheese is not the same as Parmigiano-Reggiano. To have the classification of Parmigiano-Reggiano, the cheese must contain specific ingredients, age for one to three years, and come from the Parma, Modena, or Reggio Emilia region of Italy.
Authentic Parmigiano-Reggiano cheese is prepared exclusively with skimmed cow’s milk, salt, and the curdling enzyme rennet.
Parmesan cheese has a similar texture and flavor profile to Parmigiano-Reggiano. However, since the production process isn’t as closely regulated, it’s usually much more affordable.

If you have a large quantity of parmesan cheese, freezing it is an excellent way to extend its shelf life indefinitely. Wrap your parmesan cheese in parchment paper or wax paper, then place it inside a freezer bag. Frozen dairy products often have a granular texture once thawed and are best in cooked dishes.
