Shredded cheese is a versatile ingredient that can be used in a variety of dishes. However, it's important to know how long it lasts and when it goes bad to ensure food safety and maintain its flavour. The shelf life of shredded cheese can vary depending on factors such as storage methods, type of cheese, and moisture content. Proper storage techniques, such as airtight containers and freezing, can extend the lifespan of shredded cheese, but it's important to be vigilant about signs of spoilage, including odours, discolouring, and mould.

Storage methods
The shelf life of shredded cheese depends on the type of cheese and the storage method. Soft cheeses like mozzarella and cheddar have a high moisture content, making them more perishable, while hard cheeses like Parmesan and Swiss have a lower moisture content and higher salt content, aiding in their preservation.
Fridge Storage:
- Reseal opened packages tightly or transfer the cheese to an airtight container.
- Wrap hard cheeses like Parmesan in wax paper, parchment paper, or cheese paper before placing them in an airtight container.
- Store different types of cheese separately to avoid transferring flavours and odours.
- Keep the cheese drawer organised and label each package with the cheese type and best-by date.
- Regularly clean the cheese drawer to prevent the growth of mould or bacteria.
Freezer Storage:
- Freeze shredded cheese in its original unopened package or transfer it to a freezer-safe bag or container after removing excess air.
- Spread the cheese on a baking sheet to freeze individually, then transfer to a freezer bag for longer-term storage.
- Defrost frozen shredded cheese in the refrigerator before use, and consume within a few days of thawing.
Additionally, it is important to use your senses to determine if the shredded cheese has gone bad. Mould, discolouration, off-odours, or a change in texture are indications that the cheese has spoiled and should be discarded.

Type of cheese
The shelf life of shredded cheese depends on the type of cheese and storage methods. Soft cheeses like mozzarella, ricotta, and cheddar have a high moisture content, making them more perishable. Once opened, soft cheeses will last around one to two weeks in the fridge. It's important to discard soft cheeses once mold appears, especially if it's red or black.
On the other hand, hard cheeses like Parmesan, Swiss, and Gouda have a lower moisture content and higher salt content, making them last longer. Unopened, hard cheeses can last up to six months in the fridge, and once opened, they will stay fresh for at least three to four weeks.
Freezing is an option for both soft and hard cheeses to extend their shelf life. Frozen shredded cheese should be consumed within six months, regardless of the type.
It's worth noting that some pre-shredded cheeses are coated in cellulose or powdered potato starch to prevent clumping, which may affect their melting ability and taste. Grating your own cheese may be preferable for certain dishes, like mac 'n' cheese, where melting is crucial.

Expiry dates
The expiry date of shredded cheese depends on several factors, including the type of cheese, whether it has been opened, and how it is stored.
Hard cheeses, such as Parmesan and Swiss, last longer than softer cheeses. Unopened hard cheeses can last up to six months in the fridge, according to the USDA. Once opened, hard cheeses will stay fresh for at least three to four weeks in the refrigerator, provided they are stored properly. This involves wrapping the cheese in wax, parchment, or cheese paper and then sealing it in an airtight container.
Soft cheeses, such as mozzarella and cheddar, have a higher moisture content, which makes them more perishable. Unopened soft cheeses will last around a week in the fridge, while opened soft cheeses should be consumed within one to two weeks.
Shredded cheese that has been frozen can be stored for up to six months. To freeze shredded cheese, place the unopened package directly in the freezer. If the package has been opened, transfer the cheese to a freezer-safe bag or container, removing as much excess air as possible before freezing.
It is important to use your best judgment when consuming shredded cheese, even if it is before the expiry date. If the cheese has any off odors, discolouration, or spots of mold, it should not be eaten.

Signs of spoilage
The shelf life of shredded cheese depends on a variety of factors, including the type of cheese, storage methods, and whether it has been opened. It's important to keep an eye out for any signs of spoilage to ensure food safety.
One of the most common signs of spoilage in shredded cheese is the presence of mould. Mould can appear as spots on the surface of the cheese, and it indicates that the cheese is no longer safe to eat. It is important to discard any cheese with mould, especially if it is red or black mould.
Another sign of spoilage is an off odour or unusual smell. Cheese naturally has a distinct smell, but when it starts to spoil, it may emit an unpleasant or sour odour. If the cheese smells off, it is best to discard it.
Discolouration is also an indication of spoilage. If the shredded cheese has changed colour or developed odd spots, it is likely to have gone bad. This discolouration could indicate the growth of bacteria or mould beneath the surface.
Texture is another indicator of spoilage. If the shredded cheese feels slimy, sticky, or significantly drier than usual, it has probably spoiled. Fresh cheese should have a consistent texture, and any deviations from its normal feel could indicate deterioration.
It's worth noting that proper storage can help extend the shelf life of shredded cheese. Storing it in an airtight container or resealable bag in the refrigerator can keep it fresh for longer. Additionally, wrapping hard cheeses in wax, parchment, or cheese paper before placing them in an airtight container can further prolong their freshness.

Freezing shredded cheese
Shredded cheese can be frozen to extend its shelf life. Freezing shredded cheese is a good way to prevent it from spoiling before you can use it. The best shredded cheeses to freeze are everyday blocks, such as cheddar, Monterey Jack, and part-skim mozzarella. These cheeses are commonly used in dishes like mac and cheese and pizza.
To freeze shredded cheese, it is recommended to shred the cheese first and then place it in an airtight, resealable plastic freezer bag. You can also put the store-bought bag of shredded cheese directly into the freezer. When freezing shredded cheese, it is important to remove as much air from the bag as possible to prevent freezer burn. Frozen shredded cheese can be stored for up to two to three months.
When using frozen shredded cheese, it is best to cook with it frozen rather than letting it thaw first, as the cheese's texture might be altered slightly after freezing. The change in texture is unnoticeable once the cheese is melted. Frozen shredded cheese can be used straight from the freezer by breaking off or shaking out the desired amount. It can also be defrosted overnight in the refrigerator or at room temperature for about 20 minutes.
Some people prefer to shred their own blocks of cheese and then freeze them, as pre-shredded cheese is often coated in cellulose to prevent sticking, which can affect its melting properties. Additionally, shredding your own cheese allows you to choose the type of cheese you prefer and avoid any potential allergens or additives in pre-shredded cheese.

Frequently asked questions
Once opened, shredded cheese will last around one to four weeks in the refrigerator, depending on the type of cheese. Hard cheeses like Parmesan and Swiss should be eaten within a month of purchase, while soft cheeses like cheddar and mozzarella will only be good for one to two weeks after opening.
Yes, you can freeze shredded cheese. If the package is unopened, you can place it directly in the freezer. If it has been opened, transfer the cheese to a freezer-safe bag or container, removing as much excess air as possible. Frozen shredded cheese should be consumed within six months.
Your senses are one of the best ways to tell if shredded cheese has gone bad. Look for any discolouring or spots of mould, and avoid cheese with a strange odour. If you notice any of these signs, throw the cheese away.
Shredded cheese has a shorter shelf life than block cheese because shredding increases the surface area exposed to oxygen, moisture, and bacteria, which can cause the cheese to spoil faster.
To make shredded cheese last longer, focus on proper storage techniques. Transfer the cheese to an airtight container or reseal the package tightly. Keep the cheese in a cool, dry place, such as the refrigerator or freezer, and ensure it is not exposed to excess moisture, as mould grows quickly on wet cheese.
