Parm Cheese: How Long Does It Last?

Parmesan cheese is a hard, nutty-flavoured cheese made from cow's milk. It is a popular addition to pasta dishes, soups, and salads. When stored properly, Parmesan can last for several weeks to months. If unopened and in its original packaging, it can last for several months beyond its expiration date. Once opened, its shelf life depends on how well it is sealed and stored. To extend the shelf life, it is recommended to store opened Parmesan in an airtight container or resealable bag in the refrigerator.

Parmesan cheese can last 7-9 months in the fridge if unopened

Parmesan cheese is a hard cheese with a long shelf life, especially when stored properly. An unopened block of Parmesan can last seven to nine months in the refrigerator.

To achieve this, the cheese must be stored correctly. Firstly, moisture will cause spoilage, so Parmesan cheese needs to breathe to prevent condensation. Wrap the cheese in parchment paper, cheesecloth, cheese paper, or wax paper. Then, cover the wrapped cheese in plastic wrap or aluminium foil to prevent it from absorbing other odours from the refrigerator. Place the cheese in a dry, cool part of the refrigerator, such as a crisper drawer.

The quality and flavour of Parmesan cheese are best when it's fresh. However, if stored correctly, an unopened block of Parmesan cheese can last seven to nine months in the refrigerator.

Once the cheese is opened, its shelf life reduces to one to two months. Grated Parmesan will only last about one week in the refrigerator. Therefore, it is important to store Parmesan correctly to prolong its shelf life.

Opened, it will last 1-2 months

Parmesan cheese is a hard cheese with a long shelf life. When opened, it will last for 1-2 months in the fridge, as long as it is stored correctly. To extend its shelf life, it should be kept in an airtight container or resealable bag in the refrigerator, stored at temperatures below 40°F (4°C).

It is important to ensure that the cheese is well-sealed to prevent it from drying out or absorbing odours from the refrigerator. Parchment paper, cheesecloth, cheese paper, or wax paper can be used to wrap the cheese, followed by plastic wrap or aluminium foil to protect it from other smells.

Additionally, moisture can cause spoilage, so it is important to allow the cheese to breathe and prevent condensation. Grated Parmesan should be stored in an airtight container, vacuum-sealed bag, or a container with a tight lid to prevent clumping and to maintain its flavour.

It is also important to check for signs of spoilage, such as mould growth, off odours, or changes in texture. While it is generally safe to cut off mould on hard cheeses, it is important to use your judgment and consider the specific storage conditions.

Grated Parmesan should be stored in an airtight container

To further prevent moisture absorption, you can add a little cornstarch, flour, or arrowroot powder to your grated Parmesan. These ingredients will absorb any excess moisture without affecting the flavour or quality of the cheese.

It is also important to store your grated Parmesan in the refrigerator at temperatures below 5°C (40°F). Cool temperatures will make it harder for the cheese to absorb moisture, preventing clumping and bacterial growth.

While grated Parmesan can be stored for several weeks, it is best to use it within two weeks to ensure optimal flavour and texture. If you are unable to use the cheese within this time frame, you can extend its shelf life by freezing it in an airtight container. Frozen grated Parmesan can last for up to six months and can be defrosted and used as needed.

Parmesan can be frozen in an airtight container or bag

Parmesan cheese is a hard, dry cheese that can be frozen to extend its shelf life. While it is not the most freezer-friendly cheese, freezing is a good option if you want to preserve your Parmesan for longer than its usual shelf life.

When freezing Parmesan cheese, it is important to use an airtight container or bag to prevent moisture from reaching the cheese. This will help to maintain its taste and texture. Wrap the cheese tightly in plastic wrap before placing it in the container or bag to ensure that it is fully protected from the air. You can also wrap the cheese in parchment paper, cheesecloth, or wax paper before wrapping it in plastic to provide additional protection from condensation.

If you are freezing grated or shredded Parmesan cheese, it is best to use a vacuum-packed freezer bag or airtight container to ensure that the cheese is protected from the air. You can also wrap the plastic-wrapped cheese in foil to provide extra protection. Mark the bag with the date and name of the contents so you know when it needs to be used.

Frozen Parmesan cheese will last for about three to six months if it is shredded or grated, and over a year if it is a wedge or block. However, it is important to note that freezing can alter the texture and taste of the cheese. Once thawed, the cheese may become crumbly and dry, making it difficult to grate. It is best to use frozen Parmesan as an ingredient in dishes such as soups or pizzas rather than as an antipasto.

Signs of spoilage include mould, off odours, or changes in texture

Parmesan cheese is a hard cheese with a long shelf life, but it can still spoil. Signs of spoilage include mould, off odours, or changes in texture.

Mould is a type of fungus that can grow on cheese. It is important to check your Parmesan cheese for mould regularly, especially if it has been stored for a long time. If you notice mould on the surface of your Parmesan cheese, it is generally safe to cut off the affected portion. However, if the mould is extensive, it is better to discard the cheese entirely.

Off odours are another sign of spoilage. Parmesan cheese should have a slightly nutty aroma. If it starts to smell sour, rancid, or otherwise unpleasant, it is likely spoiled and should be discarded.

Changes in texture can also indicate that your Parmesan cheese has gone bad. Parmesan is a hard cheese, so if it becomes crumbly, soft, or otherwise changes in texture, it is best to throw it out.

To prevent spoilage, it is important to store your Parmesan cheese properly. This includes wrapping the cheese tightly to prevent air and moisture from getting in, storing it in an airtight container or resealable bag, and keeping it in the refrigerator at temperatures below 40°F (4°C). With proper storage, an unopened package of Parmesan cheese can last for several months beyond its expiration date, while an opened package can last for up to two months. Grated or shredded Parmesan has a shorter shelf life, typically lasting about one week in the refrigerator.
