It is possible to freeze shiitake mushrooms raw or cooked, but cooking before freezing is generally recommended to avoid the mushrooms becoming mushy. To freeze shiitake mushrooms, start by cleaning and trimming the mushrooms, removing the stems, then slicing them to your desired thickness. Next, cook the mushrooms by sautéing or steaming, before leaving them to cool.

Cleaning and preparing shiitake mushrooms for freezing
Next, trim the stems of the shiitake mushrooms with a sharp knife, as they are extremely tough and fibrous. You can choose to remove the stems entirely or keep part of the stem intact, as long as it is soft and not woody. After trimming, slice the mushrooms to your desired thickness and size.
At this point, you can choose to blanch the mushrooms by placing them in boiling water for 2-3 minutes, followed by an ice water bath to stop the cooking process. This step is optional but can help preserve the texture and flavour of the mushrooms. Whether you blanched the mushrooms or not, make sure to drain and pat them dry with a clean towel or paper towel before freezing.
Finally, spread the shiitake mushrooms in a single layer on a baking tray or cookie sheet, ensuring they don't touch each other. Place the tray in the freezer until the mushrooms are frozen solid, which can take a few hours. Once frozen, transfer the mushrooms to a freezer bag or airtight container, removing as much air as possible to prevent freezer burn. Label the container with the date and contents, and store in the freezer for up to two to six months.

Cooking shiitake mushrooms before freezing
Shiitake mushrooms are edible fungi valued for their rich, savoury, and slightly earthy taste. They are commonly used in various cuisines, particularly in Asian dishes. When it comes to freezing shiitake mushrooms, there are two main options: freezing them raw or cooking them before freezing. This response will focus on the latter option, providing a detailed guide on cooking shiitake mushrooms before freezing them.
Cleaning and Preparing the Shiitake Mushrooms:
Before cooking and freezing shiitake mushrooms, it is essential to clean and prepare them properly. Start by wiping the mushrooms with a damp cloth or paper towel to remove any dirt or grit. Avoid washing the mushrooms with water, as this can make them mushy. Next, remove the stems using a sharp knife, as the stems are too tough to eat. You can save the stems for later to make a delicious mushroom stock or broth. Now, slice the mushroom caps to your desired size and thickness.
Cooking the Shiitake Mushrooms:
There are two recommended methods for cooking shiitake mushrooms before freezing: sautéing and steaming.
Sautéing:
To sauté the mushrooms, heat a pan or large skillet over medium-high heat and add butter, olive oil, or a combination of both. Add the sliced mushroom caps to the pan and sauté until they are cooked. You can also add seasonings during this process to enhance their flavour. Once cooked, remove the mushrooms from the skillet and let them cool to room temperature.
Steaming:
To steam the mushrooms, bring a pot of water to a boil. Place a steamer basket in the pot, add the sliced mushroom caps to the basket, cover, and steam for about 3 to 5 minutes. Remove the basket from the pot and let the mushrooms cool to room temperature.
Freezing the Cooked Shiitake Mushrooms:
Once the cooked shiitake mushrooms have cooled, you can transfer them to a freezer-safe container or bag. It is recommended to use an airtight container or bag to prevent freezer burn and preserve flavour and texture. Label the container or bag with the date and contents. Place the shiitake mushrooms in the freezer, where they can last for up to 6 to 12 months.
Using Frozen Cooked Shiitake Mushrooms:
When using frozen cooked shiitake mushrooms, it is best to add them to dishes that will be thoroughly cooked, such as soups, casseroles, stews, or pasta dishes. You can add them directly to the dish without thawing, but you may need to increase the cooking time to ensure they are heated through. If you prefer to thaw the mushrooms before use, place them in the refrigerator overnight to soften. Remember, once defrosted, they should be consumed immediately and not refrozen.

Freezing cooked shiitake mushrooms
Shiitake mushrooms can be frozen cooked or raw. However, freezing raw shiitake mushrooms can make them very mushy when cooked, so it is generally better to cook them before freezing.
To freeze cooked shiitake mushrooms, first, cook the mushrooms. You can either sauté them in a skillet with a little oil for 5 minutes or steam them. To steam, bring a small amount of water to a boil in a pot, add a steamer basket, place the mushrooms in the basket, cover, and cook for 3 to 5 minutes. You can also roast them in the oven. The skin on the shiitake will hold up to the heat, even when the mushrooms are young.
Once cooked, let the mushrooms cool completely. Then, transfer them to a lined baking sheet and spread them out in a single layer. Place the baking sheet in the freezer and leave until the mushrooms are frozen solid. Finally, transfer the mushrooms to freezer-safe bags or containers. Aim for a layer thickness of no more than 1/2 inch. You can store cooked shiitake mushrooms in the freezer for up to 6 to 12 months.
When you are ready to use the mushrooms, do not thaw them at room temperature as this can make them soggy. Instead, put them straight from the freezer into your cooking pot.
