Can Cheese Be Frozen To Preserve It? | Stay Fresher

There’s a special joy in finding a delicious block of cheese, perhaps on sale, or simply having a little extra after a gathering. The thought of it going to waste can be disheartening, especially when we value every bit of our nutritious food. Understanding how to properly store cheese, including freezing, can help us enjoy it longer and reduce food waste.

The Science Behind Freezing Cheese

When cheese freezes, the water content within its structure turns into ice crystals. The size and formation of these crystals directly influence the cheese’s texture upon thawing. Larger ice crystals, which form during slow freezing, can disrupt the protein and fat matrix of the cheese more significantly, leading to a crumbly or mealy consistency.

The fat content in cheese also plays a role. Fat doesn’t freeze in the same way water does, offering some protection against extreme ice crystal damage. However, the emulsion of fat and protein can still separate, particularly in cheeses with higher moisture and fat content, resulting in a drier, less cohesive product.

Which Cheeses Freeze Best (and Which Don’t)

Not all cheeses are created equal when it comes to the freezer. Hard, aged cheeses generally withstand freezing better than their softer, higher-moisture counterparts. This is due to their lower water content and denser structure, which makes them less susceptible to significant ice crystal damage.

Hard and Semi-Hard Cheeses: Your Freezer Friends

• Cheddar: Blocks or shredded cheddar freeze well, though they might become a bit more crumbly. Ideal for cooking.
• Mozzarella: Shredded mozzarella is a freezer staple for many, perfect for pizzas and casseroles. Blocks can also be frozen but may have a slightly softer texture after thawing.
• Swiss/Gruyère: These semi-hard cheeses hold up reasonably well, often used for grating or melting after thawing.
• Parmesan/Asiago: Hard grating cheeses can be frozen in blocks or pre-grated. Their texture is less affected, making them suitable for their intended use.

Soft and Fresh Cheeses: Best Avoided

Cheeses with high moisture content and delicate textures typically do not freeze well. The extensive ice crystal formation causes their structure to break down, leading to a watery, grainy, or rubbery consistency.

• Brie/Camembert: These soft, rind-ripened cheeses become mushy and lose their creamy texture.
• Cream Cheese/Ricotta: Their high moisture and delicate protein structure lead to separation and a grainy texture, making them unsuitable for most uses after thawing.
• Goat Cheese (Chèvre): While some firmer goat cheeses might tolerate freezing for cooking, fresh, soft chèvre will suffer significant textural degradation.
• Feta: Freezing feta can make it crumbly and alter its briny texture, though it might still be usable in cooked dishes where texture is less critical.

Proper Preparation for Freezing Success

The way you prepare cheese for the freezer significantly impacts its quality upon thawing. Air is the enemy of frozen food, leading to freezer burn and off-flavors. Proper wrapping is key to maintaining quality.

Optimal Wrapping Techniques

1. Double Wrapping: Wrap cheese tightly in plastic wrap or wax paper, ensuring no air pockets. Then, place the wrapped cheese into a freezer-safe bag or an airtight container. This dual layer provides robust protection against moisture loss and freezer burn.
2. Vacuum Sealing: For the best results, especially with larger blocks of hard cheese, vacuum sealing removes almost all air, drastically extending quality and preventing freezer burn.
3. Portioning: Freeze cheese in smaller, usable portions. Once thawed, cheese should ideally be consumed within a few days and not refrozen. Portioning prevents repeated thawing and refreezing of the entire block.

For shredded cheese, a light dusting of cornstarch or flour before freezing can help prevent the shreds from clumping together. This allows you to easily grab a handful for your recipes without thawing the entire bag.

Thawing and Using Frozen Cheese

Patience is a virtue when thawing cheese. Proper thawing minimizes further textural degradation and ensures food safety. The safest and most recommended method is slow thawing in the refrigerator.

The Thawing Process

1. Refrigerator Thawing: Transfer the frozen cheese, still in its original packaging, to the refrigerator. Allow at least 24-48 hours for a small block or shredded cheese to thaw completely. Larger blocks may require more time.
2. Avoid Room Temperature: Do not thaw cheese at room temperature. This can promote bacterial growth on the surface while the interior remains frozen, posing a food safety risk. According to the U.S. Department of Agriculture, perishable foods should never be thawed on the counter or in hot water, as bacteria can multiply rapidly at temperatures between 40°F and 140°F. More information on safe thawing practices can be found at USDA.gov.

Best Uses for Thawed Cheese

Once thawed, the texture of cheese will likely be more crumbly or softer than its fresh counterpart. This makes it less ideal for serving on a cheese board or slicing for sandwiches. However, it remains perfectly suitable for many culinary applications.

• Cooking and Melting: Thawed cheese excels in dishes where it will be melted, such as casseroles, gratins, sauces, and baked pasta dishes. The slight textural changes are often unnoticeable once melted.
• Grating: Hard cheeses like Parmesan or aged cheddar, even if a bit crumbly, can still be grated beautifully over dishes.
• Sauces and Dips: Incorporate thawed cheese into creamy sauces, cheese dips, or even homemade mac and cheese.

Can Cheese Be Frozen To Preserve It? — FAQs

Does Freezing Cheese Kill Bacteria?

Freezing cheese does not kill bacteria; it merely renders them dormant. Once cheese thaws, any bacteria present can become active again. This is why proper thawing in the refrigerator is essential to prevent rapid bacterial growth and maintain food safety.

Can I Freeze Cheese That Has Already Been Opened?

Yes, you can freeze cheese that has already been opened, provided it has been handled properly and is still fresh. Ensure you cut away any dry or hardened edges and rewrap it meticulously to prevent freezer burn and exposure to air.

How Long Can Cheese Stay Frozen?

For optimal quality, most hard and semi-hard cheeses can be frozen for 6 to 9 months. Hard grating cheeses like Parmesan can last even longer, up to a year, without significant quality degradation. Beyond these times, the cheese remains safe but its texture and flavor may diminish.

Will Freezing Cheese Affect Its Flavor?

Freezing can subtly alter the flavor of cheese, often making it milder or less complex. This is due to the changes in its fat and protein structure. The impact is generally more noticeable in cheeses with delicate flavor profiles compared to robust, aged varieties.

Can I Freeze Cheese Slices for Sandwiches?

While you can freeze cheese slices, their texture will likely become crumbly or mealy upon thawing, making them less ideal for sandwiches. They might break apart easily. Thawed slices are best used in melted applications like grilled cheese or quesadillas.
