Parmesan cheese, also known as Parmigiano-Reggiano, is a hard, granular cheese that is aged for at least 12 months. It is a popular cheese used in many dishes, from pasta to pizza to salads. But what happens if you find yourself with a block of Parmesan cheese that has passed its expiration date? Can you still eat it?
Understanding Expiration Dates
Expiration dates are not exact indicators of when food will go bad. They are more of a guideline to help consumers determine how long a product will be at its best quality. For most foods, the expiration date is based on the manufacturer’s estimate of how long the food will retain its flavor, texture, and nutritional value.
Parmesan Cheese and Expiration Dates
Parmesan cheese is a particularly long-lasting cheese due to its low moisture content and high acidity. This means that it can last for months, even years, beyond its expiration date. However, the quality of the cheese may start to decline over time.
Signs of Spoiled Parmesan Cheese
Even though Parmesan cheese is a relatively long-lasting cheese, it can still spoil. Here are some signs to look for:
- Mold: If you see any mold on your Parmesan cheese, it is best to discard it. Mold can produce harmful toxins that can make you sick.
- Unpleasant Odor: If your Parmesan cheese smells sour or rancid, it is likely spoiled.
- Discoloration: If your Parmesan cheese has changed color, it may be a sign of spoilage.
- Texture Changes: If your Parmesan cheese has become crumbly or mushy, it is likely spoiled.

To extend the shelf life of your Parmesan cheese, store it properly. Here are some tips:
- Wrap it tightly: Parmesan cheese should be wrapped tightly in plastic wrap or aluminum foil to prevent it from drying out.
- Refrigerate it: Parmesan cheese should be refrigerated at all times.
- Freeze it: Parmesan cheese can be frozen for up to 6 months.
Reusing Parmesan Cheese After the Expiration Date
If your Parmesan cheese has passed its expiration date but does not show any signs of spoilage, you may still be able to use it. Here are some ideas:
- Grate it: Grated Parmesan cheese can be used as a topping for pasta, pizza, or salads.
- Melt it: Melted Parmesan cheese can be used in sauces, soups, or casseroles.
- Bake it: Parmesan cheese can be baked into bread, crackers, or cookies.
Health Risks
