How Long Does Shredded Cheese Last?

The shelf life of shredded cheese can vary depending on the type of cheese and how it’s stored. Let’s break it down:

How Long Does Shredded Cheese Last

  1. Unopened Shelf Life: When stored properly in the refrigerator at a temperature below 40°F (4°C), unopened shredded cheese can last for up to 6 to 8 months. Yet, ensure to check the printed expiration date as well as the packaging for specific guidelines on storage.
  2. Opened Shelf Life: Once you open the package, the shelf life of shredded cheese changes. Here’s a general estimate for different types of shredded cheese:
    • Soft and Semi-Soft Cheeses: Soft and semi-soft shredded cheeses like feta, brie cheese, and queso fresco can last for about 1 to 2 weeks in the refrigerator after opening.
    • Hard Cheeses: Hard shredded cheeses such as Parmesan, Romano, and aged cheddar can stay fresh for around 3 to 4 weeks in the refrigerator after opening.
    • Processed Cheeses: Processed shredded cheeses, commonly found in convenience foods and dips, can maintain their quality for approximately 3 to 4 weeks in the refrigerator after opening.
    • Homemade Shredded Cheese: If you shred your own cheese at home, its shelf life will be similar to that of opened shredded cheese, which is around 1 to 2 weeks.
  3. Shredded Cheese Canisters: Some shredded cheese is sold in resealable canisters, which offer convenience and extended freshness. These canisters are designed to help maintain the cheese’s quality for a longer duration after opening, often up to 6 to 8 weeks. Always check the packaging for specific instructions and follow the recommended storage guidelines.

Remember that these timeframes are general guidelines, and it’s always best to rely on your senses and look for signs of spoilage, such as mold growth, unpleasant odor, texture changes, or unusual color.

Proper storage techniques, such as refrigeration and airtight containers, can help extend the shelf life of shredded cheese, ensuring that it stays fresh and safe to consume for as long as possible.

How to Store Shredded Cheese?

Proper storage plays a vital role in maintaining the freshness and quality of shredded cheese. Follow these guidelines to ensure optimal storage conditions:

How to Store Shredded Cheese

  1. Refrigeration: Shredded cheese should always be stored in the refrigerator at a temperature below 40°F (4°C). This helps slow down the growth of bacteria and prevents spoilage. Make sure to place the cheese in an airtight container or resealable bag to maintain freshness.
  2. Avoid Exposing to Air: Oxygen can contribute to the deterioration of shredded cheese. To prevent this, squeeze out any excess air from the packaging before sealing it tightly.
  3. Separate from Strong Odors: Cheese has a tendency to absorb odors from its surroundings. Keep shredded cheese away from pungent foods like onions and garlic to preserve its flavor.
  4. Original Packaging: If your shredded cheese comes in a resealable bag, it’s best to store it in its original packaging. These bags are designed to keep the cheese fresh for longer periods.

These are general guidelines for storing shredded cheese. However, Make sure to follow the guidelines by the cheese manufacture. For example, Tillamook have excellent guidelines that you should follow if you choose to buy cheese from them.

How to Tell if Shredded Cheese Has Gone Bad?

It’s crucial to be able to identify signs of spoilage in shredded cheese. Here are some indicators that your cheese may no longer be suitable for consumption:

How to Tell if Shredded Cheese Has Gone Bad

  1. Visible Mold: Mold growth on shredded cheese is a clear indication of spoilage. Even if the mold appears only on a small section, it’s best to discard the entire package to prevent cross-contamination.
  2. Unpleasant Odor: If your shredded cheese emits a foul or sour smell, it’s likely gone bad. Fresh cheese should have a mild, pleasant aroma.
  3. Texture Changes: If the cheese becomes excessively dry, clumpy, or slimy, it’s a sign that it has lost its freshness. Avoid consuming such cheese.
  4. Unusual Color: Any significant color changes, such as the cheese turning excessively yellow or exhibiting unusual discoloration, can indicate spoilage.

How to Freeze Shredded Cheese?

Freezing shredded cheese is an excellent way to extend its shelf life and prevent waste. Follow these steps to freeze shredded cheese properly:

How to Freeze Shredded Cheese

  1. Preparation: Divide the shredded cheese into smaller portions or use the original packaging if it’s resealable.
  2. Wrap and Seal: Wrap each portion tightly with plastic wrap or aluminum foil. Then, place the wrapped portions in a freezer-safe bag, removing any excess air before sealing.
  3. Label and Date: Don’t forget to label the bag with the type of cheese and the date of freezing. This helps you keep track of its freshness.
  4. Freeze and Thaw: Place the bag of shredded cheese in the freezer, ensuring it lies flat to prevent clumping. When ready to use, thaw the cheese in the refrigerator overnight before incorporating it into your favorite recipes.


Can I still use shredded cheese past its expiration date?

The expiration date on shredded cheese indicates the recommended period for consuming it at its best quality. However, if the cheese has been stored properly and shows no signs of spoilage, it can often be used safely for a few days beyond the expiration date.

Can I freeze shredded cheese directly in its original packaging?

While it’s possible to freeze shredded cheese in its original packaging, transferring it to a freezer-safe bag or container provides better protection against freezer burn and helps maintain its taste and texture.

Can shredded cheese be refrozen after thawing?

It’s generally not recommended to refreeze shredded cheese once it has been thawed. Thawed cheese can experience quality degradation, including changes in texture and flavor.

Are there any risks associated with eating expired cheese?

Eating expired cheese can pose several risks, including the potential growth of harmful bacteria, such as Listeria or Salmonella, which can cause foodborne illnesses. Additionally, the taste, texture, and quality of the cheese may be compromised, resulting in an unpleasant eating experience.

Can I still eat cheese left at room temperature overnight?

It is not recommended to consume cheese that has been left at room temperature for an extended period, such as overnight. Bacterial growth can occur rapidly in the danger zone, and the cheese may no longer be safe to eat. To avoid potential foodborne illnesses, discard cheese that has been left out for too long.
