Freezing is an excellent way to extend the shelf life of food, but it can be tricky to defrost certain items, like cheese, without compromising their texture and taste. The best way to thaw a block of cheese depends on the type of cheese and how much time you have. While the microwave is the fastest option, it can negatively impact the flavour and texture of the cheese. For the best results, it is recommended to defrost cheese slowly in the refrigerator.
Characteristics of the best way to thaw block cheese:
| Characteristics | Values |
|---|---|
| Time | At least 6 hours in the refrigerator for a 200-300g block. Adjust the time depending on the size of the block. |
| Temperature | Cold but not freezing. Room temperature for no more than 60 minutes for hard cheeses. |
| Method | Place the unopened package on a plate in the refrigerator. Avoid using the microwave as it can affect flavour and texture. |
| Type of cheese | Hard and semi-hard cheeses are best suited for freezing and thawing. Soft cheeses like goat cheese, brie, or Camembert may become crumbly and dry. |
| Packaging | Use an airtight container to prevent moisture loss. |
| Water bath | Can be used to thaw cheese. Submerge the sealed cheese in cool water, changing the water every 30 minutes. |
| Grating | Grating the cheese while frozen speeds up the thawing process. |

The best way is slowly in a refrigerator
The best way to thaw a block of cheese is to let it defrost slowly in a refrigerator. This method is optimal for preserving the cheese's flavour and texture. While it is possible to defrost cheese in a microwave, this can negatively impact its flavour and texture.
To defrost cheese in a refrigerator, place the unopened package of cheese on a plate and leave it in the fridge for at least 6 hours. The exact time will depend on the size of the cheese block. For example, a solid block of cheddar will take a couple of days to defrost in the fridge. If you are defrosting shredded cheese, you can use it immediately out of the freezer if you plan to melt it on hot dishes.
It is important to defrost cheese slowly because defrosting it too quickly can lead to bacterial growth and texture changes. For this reason, it is not recommended to use warm water to defrost cheese. While a cold water bath can be used to defrost cheese, this requires submerging the sealed cheese in cool water, changing the water every 30 minutes.
If you are in a hurry, there are some quicker methods to defrost cheese. You can leave hard cheese on the counter for 30-60 minutes, grate the cheese while it is still frozen, or use the microwave. However, the microwave should be used sparingly and with caution, as it can cause the cheese to become plastic-like.

Quicker methods include a cold water bath
While it is best to let cheese thaw slowly in the refrigerator, sometimes you might need to speed up the process. One quick method is to use a cold water bath. This involves submerging the sealed cheese in a bowl of cool water, and changing the water every 30 minutes. This method is also known as water bath defrosting.
If the cheese is in a freezer bag or container, place it inside a larger bowl of cool water. If the cheese is not in a bag or container, put it in a bowl that can be placed inside another bowl of cool water. Keep changing the water periodically until the cheese is defrosted.
It is important to note that warm water should not be used to defrost cheese, as it can cause the outer layers to thaw too quickly, potentially leading to bacterial growth and affecting the texture. Therefore, the water used for the cold water bath method should always be cool.
Another quick method to thaw cheese is to grate it while it is still frozen and add it directly to your recipe. This method is especially useful for recipes that call for melting cheese.

Room temperature for hard cheeses
While it is possible to defrost cheese in a microwave, this method is not recommended as it can negatively impact the flavour and texture of the cheese. The best way to defrost cheese is to do so slowly, either in a refrigerator or at room temperature.
Hard cheeses, such as cheddar, provolone, and romano, can be left to thaw at room temperature. Leaving cheese at room temperature is said to produce "happy cheese". At refrigerator temperature, cheese is left "paralysed at a flavour standstill", whereas at room temperature, the fat and protein molecules loosen up.
To defrost hard cheese at room temperature, place the unopened package of cheese on a plate and leave it at room temperature for 30 to 60 minutes. The time it takes to defrost will depend on the style of the cheese and the size of the piece. Be careful, as cheese will start to go bad if left out for more than 4 hours. Hard cheeses should be discarded if left at room temperature for more than 6 hours.
If you are not in a hurry, it is recommended that you defrost cheese in the refrigerator. Place the cheese on a plate and leave it in the fridge for at least 6 hours. The time it takes to defrost will depend on the size of the cheese, with larger blocks requiring up to 48 hours to fully thaw.

Grating while frozen for melting recipes
Freezing cheese is an excellent way to preserve it for future use, but it's important to do it correctly to maintain its quality. Hard and semi-hard cheeses, such as cheddar, jack, or parmesan, freeze and thaw without major issues. On the other hand, softer cheeses like brie, camembert, or ricotta are likely to suffer significant textural changes and may become crumbly when thawed.
When it comes to thawing frozen cheese, the best method is to let it thaw slowly in a refrigerator. Place the unopened package of cheese on a plate and put it in the fridge for at least 6 hours, depending on the size of the block. This gradual thawing process helps to preserve the flavour and texture of the cheese.
However, if you're in a hurry and need to use the cheese in a melting recipe, you can try grating the frozen cheese directly into your dish. Grating frozen cheese is a handy technique that can make your life easier. Here's how to do it:
- Place the block of cheese in your freezer for about 15 to 20 minutes, or until it feels firm. The exact time depends on the softness of the cheese.
- Take the cheese out of the freezer once it's firm enough.
- Start grating the cheese directly into your melting recipe. The cheese will continue to thaw as it cooks, ensuring it melts evenly.
By grating the cheese while it's still frozen, you can save time and avoid the need for a lengthy thawing process. This method is especially useful when you're short on time and need to add cheese to a cooked dish. So, the next time you need to thaw frozen cheese for a melting recipe, give grating a try!

Microwaving is the fastest way, but should be used sparingly
Thawing cheese slowly in the refrigerator is the best way to preserve its flavour and texture. However, if you're short on time, you can defrost cheese quickly using a microwave.
While microwaving is the fastest way to thaw cheese, it should be used sparingly and with caution. Microwaving can negatively impact the flavour and texture of the cheese, causing it to become soggy and wet. It can also lead to uneven thawing, resulting in a block of cheese that is hot and gooey on the outside but still frozen on the inside. Therefore, it is recommended to use the microwave method only when the cheese will be melted as part of a recipe.
To thaw cheese in the microwave, start with a block of hard cheese, as soft cheeses like brie or camembert will not fare well. Place the cheese in a bowl of water and microwave in 20-second intervals until thawed. Then, let it sit for 10-15 minutes to cool down.
If you have the time, it is better to thaw cheese slowly in the refrigerator. This method helps the cheese retain its texture and flavour. Place the unopened package of cheese on a plate and leave it in the fridge for at least 6 hours, depending on the size of the block. For optimal results, leave it overnight.
Other quick methods to thaw cheese include submerging the sealed package in a cold water bath, grating the frozen cheese, or leaving it on the counter for 30-60 minutes (hard cheeses only).

Frequently asked questions
The best way to thaw block cheese is to let it thaw slowly in the refrigerator over the course of 2 days. This will help the cheese retain moisture, resulting in better texture and flavour.
If you need to defrost cheese quickly, you can use the cold water bath method. Submerge the sealed cheese in cool water, changing the water every 30 minutes. You can also leave hard cheeses on the counter for 30-60 minutes or grate the cheese while it's still frozen.
Yes, you can use the microwave to defrost cheese, but this method should be used sparingly as it can affect the flavour and texture of the cheese. Only use 20- to 45-second increments and keep checking to see if the cheese has thawed.
Softer cheeses like brie, camembert, and ricotta are more likely to suffer textural and taste issues when thawed. It's best to avoid thawing these cheeses if possible.
The shelf life of thawed cheese depends on the type and how it was frozen and thawed. Hard cheeses like cheddar, provolone, and romano should be used within 3-4 weeks of thawing. Always check for signs of spoilage before consuming and discard the cheese if it smells off, has visible mould (except for blue cheese), or tastes unusual.
