How Long Is A Block Of Parmesan Good For?
Generally, a block of opened Parmesan  can last for two months, while an unopened block can last up to nine months.
To ensure that the cheese stays in good condition for as long as possible, it is important to store it in an airtight container or wrap it tightly in plastic.
Keeping it away from moisture and extreme temperatures will also help to preserve its quality.
It should be discarded when the Parmesan shows signs of spoilage, such as mold growth or a strong odor.
Additionally, it is best to consume the cheese within a month after opening the package, as the flavor may begin to fade.
Can You Put A Block Of Parmesan In The Fridge?
Yes, you can put a block of Parmesan cheese in the fridge. It should be wrapped tightly in plastic or wax paper to prevent it from drying out and to keep it from absorbing odors from other food items.
It is important to remember to bring it to room temperature before grating or slicing, as cold Parmesan can be difficult to grate or slice.
Can You Freeze It?
Yes, you can freeze a block of Parmesan cheese. This popular cheese can last for up to six months when frozen properly. To do so, grate the cheese and store it in an airtight container.
“I always have Parmigiano-Reggiano, olive oil, and pasta at home. When people get sick, they want chicken soup; I want spaghetti with parmesan cheese, olive oil, and a bit of lemon zest. It makes me feel better every time.”– Isabella Rossellini, Italian-American Actress
This will help preserve the cheese’s flavor and texture, so it can be used in recipes even after being frozen. Be sure to label the container with the date so you know how long it has been in the freezer.
Signs That Your Block Of Parmesan Has Gone Bad
- Discoloration: If your block of Parmesan has changed color from white to yellow or gray, it has gone bad.
- Mold: If you see any mold growing on your block of Parmesan, it has gone bad.
- Odor: If your Parmesan has a sour or ammonia-like smell, it has gone bad.
- Texture: If your block of Parmesan has become hard and crumbly, it has gone bad.
How To Extend the Shelf Life Of A Block Of Parmesan
First, wrap the block of cheese tightly in plastic wrap or wax paper to prevent it from drying out.
Secondly, store it in an airtight container or a resealable plastic bag and keep it in the refrigerator.
Finally, check the cheese periodically and if it starts to dry out, sprinkle a little water on it and rewrap it.
How Do You Keep It Fresh?
To keep a block of parmesan cheese fresh, you should wrap it tightly in plastic or aluminum foil.
It is important to store the cheese in a cool, dry place, such as the refrigerator, where the temperature is below 40 degrees Fahrenheit. If the cheese is exposed to temperatures higher than that, it will spoil.
Additionally, it would be best to use a clean knife every time you cut off pieces of the cheese to prevent bacteria from transferring onto the surface.
Is It Okay To Eat Parmesan Cheese With Mold?
Yes, it is okay to eat parmesan cheese with mold. The mold on parmesan cheese is a type of Penicillium  that is safe to eat.
It is what gives the cheese its unique flavor and texture. The mold helps to preserve the cheese and make it more flavorful.
However, cutting away moldy cheese parts is important before consuming it. If you are unsure of the freshness of the cheese, it is best to discard it.
Kraft Parmesan cheese typically has a shelf life of about six months after the “best when used by” date. However, it’s important to note that the cheese should be stored in a cool, dry place and refrigerated after opening.
Bad parmesan cheese will have an intense ammonia smell. It may also have a sour smell, similar to spoiled milk.

A block of Parmesan can last for several months if stored properly.
To ensure the longest shelf life, keep the block of Parmesan in a cool, dry place such as the refrigerator or a cupboard.
Additionally, make sure to wrap the block of Parmesan tightly in plastic wrap or a sealed container to prevent it from drying out.
