Freezing cheese is a great way to extend its shelf life, but it's important to note that it can affect the texture and quality. When cheese is frozen, small ice crystals form on the inside, disrupting the internal structure, and when it's thawed, water is released, causing it to become crumbly and dry. However, frozen cheese still melts very nicely, especially when grated or shredded, making it perfect for recipes like casseroles, pizzas, and grilled cheese sandwiches. Hard cheeses like cheddar, Parmesan, and Monterey Jack are ideal for freezing due to their low moisture content, while soft cheeses like Brie and fresh cheeses like queso fresco may not fare as well in the freezer.

What You'll Learn
Freezing cheese changes its texture and quality
Freezing cheese can be an effective way to increase its shelf life and reduce waste. However, it is important to note that freezing cheese changes its texture and quality.
Cheese contains a lot of water, and when frozen, this water turns into ice crystals, which disrupt the internal structure of the cheese. The formation of ice crystals damages the proteins that hold the cheese together, resulting in a crumbly and mealy texture after thawing. While the ice crystals turn back into water during the thawing process, the proteins remain broken, leading to a noticeable change in texture.
The impact of freezing on cheese texture varies depending on the type of cheese. Hard and semi-hard cheeses with lower moisture and higher fat content, such as cheddar, Swiss, and blue cheese, are generally better suited for freezing. These cheeses are ideal for melting into dishes after thawing, as their texture may become crumbly and difficult to slice. However, they still retain their melting properties.
On the other hand, soft and delicate cheeses with higher water content, such as Brie, Camembert, and ricotta, are not recommended for freezing. Freezing can negatively affect their texture, making them drier and crumblier. Additionally, freezing can damage the live mold and bacteria populations essential for the ripening process in certain cheeses, impacting their overall sensory quality.
To minimize texture changes, it is recommended to shred or grate hard cheeses before freezing and use them as ingredients in cooked dishes rather than eating them fresh. Thawing frozen cheese in the refrigerator and allowing it to breathe can also help retain moisture and improve texture.

Some cheeses are better suited for freezing
While it is possible to freeze most cheeses, some are better suited for freezing than others. The freezing process can cause changes in the texture of the cheese, making it drier, crumbly, and less meltable. Therefore, cheeses that are intended to be cooked or melted after thawing are better suited for freezing.
Hard and semi-hard cheeses with lower moisture and higher fat content, such as cheddar, Monterey Jack, and Parmesan, are well-suited for freezing. These cheeses are ideal for grating, shredding, or melting after being frozen. Blocks or large chunks of these cheeses can be frozen, but it is important to cut them into smaller pieces and tightly wrap them before placing them in the freezer.
Semi-soft cheeses like mozzarella, pizza cheese, and shredded cheese also freeze relatively well. Frozen mozzarella can still be used on pizzas as it melts in the oven. However, the freezing process may negatively affect its texture and melting properties, especially if stored for longer periods.
Some soft cheeses, such as goat cheese, can also be frozen. However, most soft cheeses, including cottage cheese, ricotta, and fresh cheeses like queso fresco, paneer, and brie, are not recommended for freezing as their texture can be significantly impacted. Freezing can cause these cheeses to become tough, granular, and exude liquid.
Shredded cheese, whether store-bought or homemade, is also a good candidate for freezing as it thaws quickly and can be easily incorporated into recipes. Overall, while freezing cheese can alter its texture, it is still a useful method for extending the shelf life of certain types of cheese and reducing food waste.

Freezing cheese extends its shelf life
Freezing cheese is an effective way to extend its shelf life. Freezing food has been used as a preservation method for over 3,000 years, and it is especially useful for cheese, which can be expensive and tends to spoil quickly. Freezing cheese can prevent it from going bad, saving you money and reducing food waste.
However, it is important to note that freezing cheese will alter its texture. When cheese is frozen, its water and fat content form ice crystals that can damage the protein structure of the cheese. This can make the cheese crumbly, mealy, and difficult to slice, even after it has been thawed. The quality of the cheese can change, with some types changing more dramatically than others. For example, soft cheeses like brie, Camembert, and ricotta have a higher water and fat content and can be frozen, but their texture will be negatively affected.
Hard and semi-hard cheeses with lower moisture and higher fat content are better suited for freezing. This includes cheeses like cheddar, Monterey Jack, and Parmesan. Blocks or large hunks of these cheeses are ideal for freezing, and they can be frozen in their original packaging if unopened. Shredded hard cheeses can also be frozen, but it is recommended to use them within six to nine months to avoid a loss in quality.
If you plan to freeze cheese, it is important to properly prepare it for storage. Portion the cheese into quantities that you are likely to use at one time, as you should not refreeze cheese that has been previously frozen and thawed. Remove as much air as possible from the packaging and store it in a resealable plastic bag or airtight container. To thaw frozen cheese, place it in the refrigerator for 12 hours or overnight, allowing it to naturally retain some of its moisture.

Cheese should be frozen rapidly to prevent ice crystals
Freezing is an effective way to increase the shelf life of cheese, reduce waste, and save money. However, it can alter the texture of the cheese, making it drier, crumbly, and less versatile. This happens because when cheese is frozen, its water and fat content form ice crystals that can damage the protein structure of the cheese, which contributes to its texture and how it performs under heat.
To prevent the formation of large ice crystals, cheese should be frozen rapidly. Rapid freezing minimizes the growth of ice crystals and reduces the damage to the cheese's protein structure. This can be achieved by cutting the cheese into smaller pieces, wrapping them tightly, and placing them in the freezer for short intervals, allowing them to thaw slightly between intervals. This gradual freezing method helps prevent ice crystals from forming and expanding, thus preserving the cheese's texture and quality.
Additionally, the type of cheese also plays a role in its freezing behavior. Hard and semi-hard cheeses with lower moisture and higher fat content, such as cheddar, Monterey Jack, and Parmesan, are better suited for freezing. Soft cheeses like Camembert, Brie, and Ricotta have higher water content and are more susceptible to texture changes during freezing.
When using frozen cheese, it is recommended to grate, crumble, or melt it. Thawed cheese may not be suitable for dishes that require a creamy texture, such as Caprese salad or deli sandwiches. It is also important to note that freezing does not significantly affect the flavor of the cheese but mainly impacts its texture.

Frozen cheese is best grated, melted, or crumbled
Freezing cheese is a great way to increase its shelf life and reduce waste. However, it is important to note that not all cheeses freeze well, and the texture and quality of the cheese may be affected.
Hard and semi-hard cheeses with lower moisture and higher fat content are best suited for freezing. This includes cheeses like cheddar, Swiss, brick cheese, and blue cheese. These cheeses tend to become crumbly and mealy after freezing and may be harder to slice. However, they can still be melted and used in dishes such as grilled cheese sandwiches or casseroles.
Soft cheeses like brie, Camembert, ricotta, and cottage cheese have a higher water and fat content and are not as well-suited for freezing. Freezing can significantly damage their structure, and they may become watery and crumbly when thawed.
Some semi-soft cheeses like mozzarella, pizza cheese, Stilton, and soft goat cheese are suitable for freezing but may have negatively affected texture and melting properties. Grated or shredded hard cheeses like Parmesan and Romano can be frozen but may lose quality, so it is recommended to refrigerate them instead.
When freezing cheese, it is best to grate or crumble it first and portion it into small, usable quantities. Store each portion in an airtight, freezer-safe container or a resealable plastic bag with as much air removed as possible. Label the container or bag with the date and use the cheese within two to three months.
To thaw frozen cheese, place it in the refrigerator overnight or for about 12 hours. This will allow the cheese to retain some of its moisture and texture. Once thawed, the cheese is best suited for dishes where it will be grated, melted, or crumbled, such as casseroles, mac and cheese, or grilled cheese sandwiches. It may not be ideal for dishes where the cheese needs to be sliced or served plain.
