Parmesan cheese is a beloved ingredient in many dishes, from pasta to salads to soups. But what happens when you buy a big block of Parmesan and can’t use it all at once? How long does Parmesan cheese last in the fridge?

The answer is that it depends on the type of Parmesan cheese you have and how it’s stored. Here are some general guidelines:

Grated Parmesan:
If you have grated Parmesan cheese that’s been opened but stored properly, it should last about 3 to 4 weeks in the fridge. It’s important to keep the cheese tightly sealed in its original packaging or transfer it to an airtight container. This will prevent moisture and bacteria from getting in and spoiling the cheese.

Block Parmesan:
If you have a block of Parmesan cheese, it can last much longer than grated Parmesan. In fact, if stored properly, it can last up to 6 months or even longer.

To store a block of Parmesan, wrap it tightly in plastic wrap or aluminum foil and then place it in an airtight container or resealable bag. This will help prevent the cheese from drying out and developing mold.

How to tell if your Parmesan has gone bad:
Even if you’ve stored your Parmesan properly, there’s still a chance that it could go bad before its expiration date. Here are some signs that your Parmesan has gone bad:

– Mold: If you see any mold on your Parmesan, even just a little bit, throw it away immediately.
– Smell: If your Parmesan smells sour or unpleasant, that’s another sign that it’s gone bad.
– Texture: If your grated or shredded Parmesan feels clumpy or slimy instead of dry and crumbly, that’s another indication that it’s spoiled.

  • Pro tip: If you’re not sure whether your Parmesan cheese is still good, you can always do a taste test. If it tastes off or sour, it’s time to toss it.

How to properly store Parmesan cheese:

To maximize the shelf life of your Parmesan cheese, it’s important to store it properly. Here are some tips:

– Keep it cool: Parmesan cheese should always be stored in the fridge. This will help prevent bacterial growth and keep the cheese fresh. – Keep it dry: Moisture is the enemy of Parmesan cheese.

That’s why it’s important to keep the cheese tightly wrapped and sealed in an airtight container or resealable bag. – Don’t freeze it: While some cheeses can be frozen, Parmesan is not one of them. Freezing can cause the cheese to become crumbly and lose its flavor.

In conclusion:

Parmesan cheese can last anywhere from a few weeks to several months depending on how it’s stored. Grated Parmesan should be used within 3 to 4 weeks of opening, while block Parmesan can last up to 6 months or longer if stored properly.

To ensure that your Parmesan stays fresh, keep it tightly sealed in an airtight container and store it in the fridge. And if you’re ever unsure whether your Parmesan has gone bad, don’t take any chances – simply throw it away.
