Parmesan cheese is a popular Italian cheese that is known for its strong and nutty flavor. It is commonly used in various dishes such as pasta, pizza, and salads.

Due to its popularity and long shelf life, many people wonder if it can be canned for later use. In this article, we will explore whether or not Parmesan cheese can be canned.

What is Canning

Canning is a process of preserving food by sealing it in an airtight container. It involves heating the food to a high temperature to kill bacteria and other microorganisms that can cause spoilage. The food is then sealed in a container such as a jar or can.

Is it Safe to Can Parmesan Cheese

Unfortunately, Parmesan cheese cannot be safely canned at home. This is because cheese contains moisture which creates an environment that is conducive to bacterial growth. Even if you were able to remove all of the moisture from the cheese, it would still not be safe to can due to the risk of botulism.

Botulism is a rare but serious illness caused by a toxin produced by the bacterium Clostridium botulinum. This bacterium thrives in environments with low oxygen levels such as canned foods. Symptoms of botulism include muscle weakness, paralysis, and even death.

How Should Parmesan Cheese Be Stored

While Parmesan cheese cannot be canned, there are several ways to store it safely for later use. One of the most common ways is to store it in an airtight container in the refrigerator. This will help prevent moisture from getting into the cheese which can cause spoilage.

Another way to store Parmesan cheese is by freezing it. Simply grate the cheese into small pieces and place them in an airtight container or freezer bag. When you are ready to use it, simply thaw it in the refrigerator overnight.


In conclusion, Parmesan cheese cannot be safely canned at home due to the risk of botulism. However, there are several safe ways to store Parmesan cheese for later use such as storing it in an airtight container in the refrigerator or freezing it. By following these storage methods, you can safely enjoy your favorite Italian cheese for longer periods of time.
