Shredded Block Cheese: How Long Does It Last?

Shredded cheese is a convenient way to add flavor to a variety of dishes, but how long does it last? Whether you shred the cheese yourself or purchase it pre-shredded, the shelf life is typically 3-5 days in the refrigerator. This is because shredded cheese has a larger surface area exposed to oxygen, which accelerates spoilage. To extend the shelf life, shredded cheese can be frozen.

When it comes to the type of cheese, harder cheeses tend to last longer than softer varieties. For example, shredded mozzarella, a soft cheese, will only last 5 days after shredding, while a block of the aged variety will last at least a couple of weeks.

To maximize the shelf life of shredded cheese, it is important to store it properly. Use a sealed container or bag, and if you need to handle the cheese with your hands, make sure they are washed first. Additionally, it is recommended to separate large amounts into smaller bags or containers to avoid contamination.

Shredded cheese lasts 3-5 days in the fridge

The shelf life of shredded cheese is relatively short compared to blocks of cheese. An unopened package of shredded cheese can be stored in the fridge for at least a week or two past its printed date. However, once opened, shredded cheese only retains its quality for about 3 to 5 days.

When to Discard Shredded Cheese

It is recommended to discard shredded cheese if:

• It is too old. An unopened package that is more than a couple of weeks past its date or opened shredded cheese that has been stored for more than 5 to 6 days should be discarded.
• It has signs of mold. Unlike blocks of hard cheese, where moldy parts can be cut off, the same does not apply to shredded cheese. If there are signs of mold, the entire package should be thrown out.
• It smells off. If the cheese has a strange or sourish odour, it is no longer safe to consume.
• It feels wet or spongy. Although texture changes are not common in shredded cheese, it is best to discard it if the texture has altered.

How to Store Shredded Cheese

To ensure the freshness of shredded cheese, it is recommended to:

• Store it in a sealed container or bag in the fridge.
• Use a clean utensil to remove the cheese from the package to avoid contamination.
• Wash your hands before handling the cheese with your hands.
• Keep the package sealed tightly when not in use.
• Separate the shredded cheese into smaller bags or containers if you have a large amount to prevent excess exposure to air.
• Freeze any excess cheese if you do not intend to use it within the next few days.

Types of Cheese for Shredding

Common types of cheese that are shredded include:

• Mozzarella (aged variety sold in blocks)
• Cheddar
• Swiss
• Colby Jack
• Mexican Blend

It can be frozen to last longer

Shredded cheese can be frozen to last longer. It is a great option if you want to make your shredded cheese last longer than 3-5 days.

Freezing shredded cheese is a simple process. All you need to do is put the shredded cheese in a plastic zippered bag and place it in the freezer. You can also use a hard-sided box if you have the space. The shredded cheese can be used directly from the freezer for either cooked or cold purposes. It thaws quickly, so if you sprinkle some on a salad or wrap, it will likely be thawed by the time you get your drinks and dressings.

If you want to keep your shredded cheese from sticking together, you can dust a small amount of flour or cornstarch over the shreds and gently toss it with your hands until lightly coated.

You can also freeze blocks of cheese and grate them as you need them. This will help the cheese last longer and also make it easier to grate.

Block cheese lasts much longer

Shredded cheese, on the other hand, only lasts three to five days after opening, whether it's store-bought or homemade. This is because shredded cheese has a larger surface area exposed to the air, which makes it more prone to bacterial growth.

Therefore, if you want your cheese to last longer, it's best to keep it in block form and shred it as needed. This way, you can take advantage of the longer shelf life of block cheese while still enjoying the convenience of shredded cheese when required.

Additionally, shredding your own cheese has several other benefits. Firstly, it tastes better and melts better due to the absence of anti-caking agents and other additives commonly found in pre-shredded cheese. Secondly, it can save you money, as pre-shredded cheese is usually more expensive than block cheese. Finally, you have more options when it comes to cheese varieties, as pre-shredded cheese is typically only available in a limited range of options.

To store block cheese, wrap it in wax, parchment, or cheese paper and keep it in the fridge. This will help maintain its moisture and maximise its shelf life.

Freshly grated cheese melts better

On the other hand, freshly grated cheese lacks these additives, allowing your recipes to turn out less clumpy and much smoother. For example, when making a Baked Ham and Cheese Pasta with Béchamel Sauce, using freshly grated cheese ensures that the cheese melts into the cream properly, creating a luxurious sauce that coats the pasta evenly.

Additionally, grating your own cheese gives you more options beyond the typical Mexican Blend, Colby Jack, Mozzarella, and Swiss varieties found in pre-shredded packages. By grating your own cheese, you can explore the thousands of other delicious cheese options available, such as Parmigiano Reggiano, which has a protected designation of origin and must comply with strict regulations regarding its production and ingredients.

In summary, freshly grated cheese melts better due to the absence of preservatives found in pre-shredded cheese, resulting in smoother, less clumpy dishes. It also provides greater flexibility in terms of cheese variety and allows you to avoid unnecessary additives in your food.

Grating your own cheese saves money

Grating your own cheese can be a great way to save money. Here are some reasons why:

It is more cost-effective

Buying blocks of cheese and grating them yourself is often cheaper than buying pre-shredded cheese. You are paying for the convenience of having the cheese pre-shredded, and this labour cost is reflected in the price. By grating your own cheese, you can save money on your grocery bill.

You get more cheese for your money

When you buy pre-shredded cheese, you are not only paying a premium for the labour, but you are also paying for additives and preservatives that help to keep the cheese from clumping together. These additives can make up a significant portion of the bag, meaning you get less cheese for your money. With block cheese, you get more cheese per ounce, and it will likely last longer too.

It tastes better

Freshly grated cheese tastes better than pre-shredded cheese. The additives in pre-shredded cheese can affect the flavour and texture, giving it a powdery or starchy taste and a clumpy texture when melted. Freshly grated cheese melts better and has a smoother, more luxurious texture. It also has a fresher, creamier taste because it doesn't contain preservatives.

It is more versatile

Pre-shredded cheese usually comes in a limited number of varieties, such as Mexican blend, Colby Jack, or Mozzarella. When you grate your own cheese, you have a wider range of options to choose from, including specialty cheeses that you may not find in pre-shredded form. This gives you more flexibility in your cooking and allows you to experiment with different flavours.

It is healthier

Pre-shredded cheese often contains preservatives and chemicals such as potato starch, natamycin, and cellulose (wood pulp) to prevent clumping and extend shelf life. These additives are not necessary when you grate your own cheese, resulting in a healthier, more natural product.
