Oyster mushrooms can be frozen with relative ease and will remain edible for up to a year. However, freezing them raw may affect their texture and taste, so it is recommended to cook them at least partly before freezing. They can be blanched, sautéed, or fried before freezing, but frying will infuse them with the flavour of the fat used, which may not be desirable for certain dishes. Frozen oyster mushrooms are best used in cooked dishes such as soups, sauces, stir-fries, and stews, rather than eaten raw.

What You'll Learn
Oyster mushrooms can be frozen raw or cooked
If you are freezing raw oyster mushrooms, you can place them directly into a freezer bag or container without any processing. However, blanching them first will help to preserve their flavour and texture. To blanch, prepare a pot of boiling water, two colanders, a bowl, and some plastic freezer bags. Slice the mushroom caps, then submerge them in the boiling water for 30 seconds to one minute. Strain the mushrooms and place them in a colander suspended over a bowl to collect the drain water. Allow the mushrooms to cool, then pack them into freezer bags and place them in the freezer.
Oyster mushrooms can also be sautéed or fried before freezing. This will prevent them from becoming soggy when defrosted. However, fried mushrooms will take on the flavour of the fat used for cooking, which may not complement all dishes. If you sauté or fry your mushrooms before freezing, there is no need to recook them. Simply add them to your dish towards the end of cooking to warm them through.

Freezing them in an airtight container or bag is best
Oyster mushrooms can be frozen with relative ease. Freezing them in an airtight container or bag is best.
Firstly, it is important to note that oyster mushrooms should be cooked at least partly before freezing. If you try freezing them fresh, they may turn into a soggy mass or take on a rubbery texture. They can be blanched or fried before freezing. If frying, note that the mushrooms will take on the flavour of the fat you cook them in.
To blanch oyster mushrooms, prepare a pot of boiling water, two colanders, a bowl, and plastic freezer bags. Slice the mushroom caps and submerge them in the boiling water for 30 seconds to one minute. Then, strain the mushrooms with the colander and place them in another colander suspended over a bowl to collect the drain water. Allow the mushrooms to cool, and then pack them into freezer bags and place them in the freezer.
If you are freezing raw oyster mushrooms, you can place them directly into a freezer bag or container. However, this does not preserve the mushroom's flavour or texture as well as blanching does. To prepare raw oyster mushrooms for freezing, soak them in cold water, pick out any damaged pieces or parts that look slimy, and let them dry. You can also cut up larger pieces into bite-sized slices. Place the mushrooms on a cooking tray lined with parchment paper and freeze them overnight. Once frozen, put the mushrooms in an airtight container or zip-top bag and store them in the freezer.
Frozen oyster mushrooms are best used in soups, sauces, or stews rather than eaten raw, as freezing can dull their flavour. When you are ready to use frozen oyster mushrooms, simply warm them up by mixing them into your meal as it finishes cooking. If you recook them, you risk compromising their nutritional value, flavour, and texture.

They can be blanched or fried before freezing
Oyster mushrooms can be blanched or fried before freezing. This is because freezing raw mushrooms can negatively affect their texture, taste, and nutritional profile.
To blanch oyster mushrooms, prepare a pot of boiling water, two colanders, a bowl, and plastic freezer bags. Slice the mushroom caps, saving the stems for stocks, and submerge the slices in the boiling water for 30 seconds to one minute. Then, strain the mushrooms with a colander and place them in another colander suspended over a bowl to collect the drain water. Allow the mushrooms to cool, then pack them into freezer bags and place them in the freezer.
Alternatively, you can fry oyster mushrooms before freezing. However, frying will impart a flavour to the mushrooms that may not complement certain dishes. To fry oyster mushrooms, dry the moisture on the surface completely before frying. You can also sauté the mushrooms in salted butter until they are almost completely done, then let them cool to room temperature before freezing.
Regardless of whether you blanch or fry your oyster mushrooms, it is important to package them securely to prevent freezer burn and prolong their shelf life.

Frozen oyster mushrooms are best used in cooked dishes
Oyster mushrooms can be frozen raw or cooked. However, freezing them raw may affect their flavour and texture, resulting in a soggy mass when thawed. Frozen oyster mushrooms are therefore best used in cooked dishes, where their texture and taste can be masked.
To freeze oyster mushrooms, they should first be cleaned and cut into bite-sized slices. They can then be blanched by submerging them in boiling water for 30 seconds to a minute. After blanching, they should be strained and left to cool before being placed in freezer bags and stored in the freezer.
Freezing cooked oyster mushrooms is also an option. Before freezing, they should be sautéed or fried. Fried mushrooms will absorb the flavour of the fat they are cooked in, so this should be considered when planning to use the frozen mushrooms in future dishes. Sautéed mushrooms can be added directly to a dish and warmed up without compromising their nutritional value, flavour, or texture. Fried mushrooms can be used in dishes such as fried oyster mushrooms or blended burgers.
Frozen oyster mushrooms can be added to cooked dishes such as soups, stir-fries, pasta sauces, gravies, and stroganoff. They can also be used as a topping for pizza or added to omelettes and quesadillas.

They can be defrosted at room temperature or in the fridge
Oyster mushrooms can be frozen raw or cooked. However, freezing them raw may result in a soggy, malformed mass upon defrosting. To avoid this, you can blanch or fry the mushrooms before freezing them. If you choose to fry them, be aware that they will take on the flavour of the fat you cook them in.
When you're ready to use your frozen oyster mushrooms, you can defrost them at room temperature or in the fridge. Leaving them to thaw at room temperature is a quick option if you're in a hurry, but be aware that they may release water during the process, resulting in a soggy texture. If you want to avoid this, it's best to defrost them slowly in the fridge. However, don't leave them in the fridge for longer than 24 hours, as this may compromise their texture, taste, and freshness.
If you sautéed your mushrooms before freezing them, you don't need to recook them. Simply add them to your dish towards the end of cooking to warm them up. If you try to recook them, you may compromise their nutritional value, flavour, and texture.
Frozen oyster mushrooms are best suited for cooked dishes such as soups, sauces, stir-fries, and stews. They can be added directly to these dishes during cooking to defrost and warm through.
