Can Cheese Be Refrozen? | Expert Insights

Many of us find ourselves with leftover cheese after a meal or a good sale, leading to the freezer being a practical storage solution. The question of whether to refreeze cheese once it has thawed comes up often, and it involves understanding both food safety and how cheese changes during the freezing process.

Understanding the Impact on Cheese Quality

The primary concern with refreezing cheese relates to its texture, not necessarily its safety. Cheese contains water, and when it freezes, this water forms ice crystals. These crystals expand, disrupting the delicate protein and fat structures within the cheese. This structural damage is what leads to noticeable changes in consistency.

Upon thawing, especially after a second freeze-thaw cycle, the cheese can become crumbly, mealy, or even dry. The fat may separate, resulting in a greasy appearance. This separation occurs as ice crystals rupture the delicate emulsion of fat and water that gives cheese its smooth texture. This effect is more pronounced in cheeses with higher moisture content, where there is more water to form destructive ice crystals, and in softer cheeses where the protein matrix is less dense and offers less structural resistance to ice crystal formation.

Food Safety Considerations for Refreezing Cheese

From a food safety perspective, refreezing cheese is generally acceptable, provided it was thawed correctly the first time. The key principle here is preventing bacterial growth. If cheese was thawed slowly in the refrigerator and kept at a safe temperature (below 40°F or 4°C), it remains safe to refreeze. The FoodSafety.gov website offers comprehensive guidance on safe food handling.

The risk arises when cheese has been left at room temperature for an extended period after thawing. This allows harmful bacteria to multiply rapidly. If cheese has been outside the refrigerator for more than two hours, it should not be refrozen or even consumed, as it may have entered the “danger zone” for bacterial growth.

Thawing Safely

• Always thaw cheese in the refrigerator. This slow, steady thawing minimizes moisture loss and keeps the cheese at a safe temperature.
• Avoid thawing cheese on the countertop at room temperature.
• Do not use hot water or a microwave to thaw cheese intended for refreezing, as this can quickly bring it into unsafe temperature ranges and severely damage its texture.

Which Cheeses Handle Refreezing Best?

Not all cheeses are created equal when it comes to freezing and refreezing. The moisture and fat content play a large role in how well a cheese withstands the process.

Hard and Semi-Hard Cheeses

Harder, lower-moisture cheeses tend to fare better through freezing and refreezing cycles. Varieties like Parmesan, cheddar, Swiss, and Monterey Jack have less water, so fewer large ice crystals form. While they may still become a bit crumbly or dry, their flavor generally holds up. These cheeses are often best used for cooking after refreezing, where texture changes are less critical.

Soft and High-Moisture Cheeses

Soft cheeses, especially those with high moisture content, do not refreeze well. Ricotta, cream cheese, cottage cheese, fresh mozzarella, and brie will almost certainly suffer significant texture degradation. They can become watery, grainy, or mushy, making them unappealing for most uses. It is best to avoid refreezing these types of cheese.

Here is a quick reference for common cheese types:

Best Practices for Freezing Cheese Initially

To give your cheese the best chance of surviving a refreeze, it helps to freeze it correctly the first time. Proper preparation minimizes quality loss.

1. Portioning: Divide large blocks of cheese into smaller, usable portions before freezing. This allows you to thaw only what you need, reducing waste and the number of freeze-thaw cycles for the entire block.
2. Airtight Packaging: Wrap cheese tightly in plastic wrap, then place it in a heavy-duty freezer bag, removing as much air as possible. Vacuum sealing is even better, as it creates an oxygen-free barrier, which is highly effective at preventing freezer burn. Freezer burn, caused by dehydration and oxidation from air exposure, leads to dry, discolored spots and off-flavors, further compromising the cheese’s texture and taste.
3. Labeling: Clearly label each package with the type of cheese and the date it was frozen. This helps track freshness and prevents confusion.
4. Freezer Temperature: Ensure your freezer maintains a consistent temperature of 0°F (-18°C) or colder. Consistent cold helps preserve quality.

Best Practices for Refreezing Cheese

When you decide to refreeze cheese, a few steps can help minimize further quality degradation.

1. Thawed in Refrigerator: Only refreeze cheese that has been thawed entirely within the refrigerator. If it was thawed on the counter or in the microwave, it should be used immediately or discarded.
2. Prompt Refreezing: Refreeze the cheese as soon as you determine you won’t use it. Do not let it sit in the refrigerator for days after thawing before refreezing.
3. Anticipate Quality Loss: Set realistic expectations. The cheese will likely be more crumbly or dry than after the first freeze. It might not be ideal for a cheese board.
4. Consider Intended Use: Plan for the refrozen cheese to be used in cooked dishes where texture changes are less noticeable.

Maximizing Refrozen Cheese Use

Even with texture changes, refrozen cheese can still be a valuable ingredient. Its altered texture often makes it a good candidate for melting applications.

Grating refrozen cheese can be easier if it’s slightly crumbly. It works wonderfully in sauces, casseroles, and on pizzas or baked pasta dishes. The melting process helps to reintegrate some of the separated fats and moisture, making the texture more palatable than if eaten raw.

Here are some ideas for using refrozen cheese effectively:

Storage Duration and Quality

While cheese can be refrozen safely, its storage duration in the freezer is cumulative. The quality of cheese, even hard varieties, begins to decline after about 6-9 months in the freezer. Refreezing shortens this window for maintaining optimal quality.

The USDA provides guidelines for freezer storage, emphasizing that freezing keeps food safe indefinitely, but quality decreases over time. For refrozen cheese, aim to use it within 2-3 months to enjoy its best remaining qualities, especially if it’s a hard or semi-hard variety.
