Mushrooms are a versatile ingredient that can be frozen to extend their shelf life. Freezing mushrooms can be a great way to avoid waste and preserve their nutrients, but it can also affect their quality, texture, and nutritional value. Before freezing, it is important to clean and prepare the mushrooms by wiping them with a damp paper towel to remove any dirt. The stems can be trimmed, and the mushrooms can be sliced or left whole, depending on their size and intended use. Mushrooms can be frozen raw or cooked, and various methods such as steaming, sautéing, or blanching can be used to prepare them for freezing. Frozen mushrooms can be stored in airtight containers or freezer bags for up to a year and used in soups, sauces, casseroles, or other recipes.

Clean and prepare the mushrooms
Before freezing Tibetan mushrooms, it is important to clean and prepare them properly to ensure they retain their flavour and texture. Here is a step-by-step guide:
Cleaning:
- Use a damp paper towel to gently wipe and clean the mushrooms. This helps remove any dirt or debris. Avoid washing the mushrooms under running water, as they tend to absorb water and become mushy, both when cooked and frozen.
- Alternatively, use a brush or cloth to scrub and brush off any visible dirt or residue. You can also use a paper towel to brush away any dirt gently.
Trimming and Slicing:
- Inspect the stems of the mushrooms and trim off any dried-out, woody parts. Remove the entire stems of larger mushrooms like chanterelle, shiitake, and portobello.
- Decide whether to slice or leave the mushrooms whole. Smaller mushrooms can be left whole, while larger mushrooms should be sliced or quartered.
- If slicing, use a sharp knife to cut the mushrooms into uniform pieces. The size of the slices may vary depending on your intended use.
Blanching (Optional):
- Blanching is optional but can help improve the shelf life and safety of the mushrooms. It also helps minimise discolouration.
- To blanch, soak the mushrooms in a solution of water and lemon juice or citric acid for 5-10 minutes.
- Bring a pot of water to a boil and place a steamer basket inside. Add the mushrooms and steam for 2-5 minutes.
- Immediately plunge the blanched mushrooms into ice water for the same amount of time they were steamed.
Drying:
- After cleaning, trimming, and optional blanching, ensure the mushrooms are thoroughly dried.
- Place them on a tray lined with kitchen paper or a clean cloth to absorb any remaining moisture.
Proper cleaning and preparation are crucial steps to ensure your Tibetan mushrooms retain their quality during freezing. Now that your mushrooms are clean and prepared, you can proceed to the next steps of freezing, such as sautéing, steaming, or flash-freezing.

Steam or sauté
Freezing Tibetan mushrooms is a great way to extend their shelf life and reduce food waste. Before you begin the steaming or sautéing process, it is important to clean and prepare the mushrooms. Use a damp paper towel to wipe them clean and remove any dirt. You can also trim off any dried-out parts of the stems or remove the stems entirely from certain types of mushrooms. Smaller Tibetan mushrooms can be kept whole, but most others should be sliced into uniform pieces. This ensures that they cook and freeze evenly.
Steaming
If you choose to steam your Tibetan mushrooms, start by bringing a pot of water to a boil. Place a steamer basket over the boiling water, making sure it is secure and covered. Transfer the prepared mushrooms to the basket and steam for around 3 to 5 minutes. You can also add a teaspoon of lemon juice to the water to prevent discolouration. After steaming, immediately transfer the mushrooms to an ice water bath for a few minutes. This stops the cooking process. Then, strain the water and pat the mushrooms dry with a towel.
Sautéing
To sauté your Tibetan mushrooms, heat a small amount of neutral oil or butter in a skillet over medium-high heat. You can also add a small amount of olive oil or butter for flavour. Add the mushrooms and cook for about 5 minutes, stirring occasionally, until they are tender but not squishy. Avoid seasoning the mushrooms during this process, as this will cause them to steam instead of browning. Once cooked, remove the mushrooms from the skillet and let them cool completely.
Once your Tibetan mushrooms are steamed or sautéed and cooled, it is time to freeze them. Spread the mushrooms out in a single layer on a parchment paper-lined baking sheet and place them in the freezer for about an hour, or until they are frozen solid. Finally, transfer the frozen mushrooms to a labelled, resealable freezer bag, removing as much air as possible before sealing. Frozen cooked mushrooms can last up to 6 to 9 months in the freezer.

Flash freeze
Freezing Tibetan mushrooms can be done in several ways, one of which is flash freezing. Flash freezing is a great way to preserve the texture and flavour of mushrooms and ensure they don't become mushy when cooked.
To flash freeze Tibetan mushrooms, start by cleaning and preparing the mushrooms. Wipe them with a damp paper towel to remove any dirt, and trim off any dried-out parts of the stems. You can keep small mushrooms whole, but larger ones should be sliced or quartered.
Next, cook the mushrooms slightly. You can either sauté them in a skillet with a little oil or butter over high heat for about 5 minutes, or steam them. To steam, bring an inch of water to a boil in a pot, add a vegetable steamer basket, and then add the mushrooms. Cover and steam for 3 to 5 minutes. Allow the mushrooms to cool completely after cooking.
Once the mushrooms are cooled, spread them out in a single layer on a lined baking sheet. Place the baking sheet in the freezer, making sure it's placed somewhere it won't be bumped. Freeze the mushrooms for 1 to 2 hours until they are frozen solid.
Finally, transfer the frozen mushrooms to freezer-safe bags, removing as much air as possible before sealing. Label the bags with the date, and store them in the freezer for up to 6 months to a year.
Flash freezing is a convenient way to preserve the freshness and quality of Tibetan mushrooms, ensuring they are ready to be used in your favourite recipes whenever you need them.

Store in freezer bags
Freezing Tibetan mushrooms can be a great way to avoid waste and preserve nutrients, but it's important to note that freezing may affect their quality, texture, and flavour. Here's a detailed guide on how to store them in freezer bags:
Cleaning and Preparation:
Before freezing Tibetan mushrooms, it's crucial to ensure they are fresh and clean. Use a damp paper towel to wipe them gently, removing any dirt or debris. Alternatively, brush off any visible dirt without washing them, as washing can make them soggy and more prone to freezer burn. Trim the stems, removing any dried-out parts, and consider slicing or quartering the mushrooms, especially if they are larger varieties.
Cooking Methods:
While it is possible to freeze raw mushrooms, cooking them slightly before freezing helps maintain their texture. You can steam or sauté them. To steam, bring a pot of water to a boil, add a steamer basket, and place the mushrooms inside for 3 to 5 minutes. For sautéing, heat a small amount of butter or oil in a skillet or frying pan over medium to high heat and cook the mushrooms for about 5 minutes until tender but not squishy. Allow the mushrooms to cool completely after cooking.
Flash Freezing:
After cleaning, preparing, and cooking the mushrooms, it's time to flash freeze them. Spread the mushrooms in a single layer on a lined baking sheet or tray. Place the sheet in the freezer for 1 to 2 hours until the mushrooms are frozen solid. This technique ensures the mushrooms freeze individually and prevents them from sticking together.
Storing in Freezer Bags:
Once the mushrooms are frozen solid, transfer them to freezer-safe bags, such as resealable freezer bags or Stasher bags. Remove as much air as possible from the bags before sealing to prevent freezer burn and extend the mushrooms' shelf life. Label the bags with the date, either by writing directly on the bag or using a sticker. Store the bags horizontally in your freezer.
Properly prepared and stored Tibetan mushrooms can last in the freezer for up to 6 months to a year. When ready to use, add the frozen mushrooms directly to hot recipes, such as soups, casseroles, or pasta dishes. Alternatively, thaw them overnight in the fridge before cooking.

Use within a year
When freezing Tibetan mushrooms, it's important to note that they should be used within a year for optimal freshness and to avoid freezer burn. Here are some detailed steps to guide you through the process:
Cleaning and Preparing the Mushrooms
Start by cleaning the mushrooms with a damp paper towel to remove any dirt. Alternatively, you can gently brush off any visible dirt, but avoid washing them as this can make them soggy. Trim the stems, removing any dried-out parts, and decide whether to keep them whole or slice them. Smaller mushrooms can be left whole, while larger varieties should be sliced or quartered.
Cooking the Mushrooms
Before freezing, it's recommended to cook the mushrooms slightly to improve their texture and safety. You can sauté them in a skillet with a little oil or butter over medium-high heat for about 5 minutes, stirring frequently. Another option is to steam the mushrooms by placing them in a steamer basket over boiling water with a teaspoon of lemon juice for 3 to 5 minutes. Allow the mushrooms to cool completely after cooking.
Flash Freezing
Spread the cooked mushrooms in a single layer on a lined baking sheet or tray. Place the sheet in the freezer for 1 to 2 hours until the mushrooms are frozen solid. Flash freezing them individually ensures they won't stick together and allows you to scoop out the desired amount for future recipes.
Storing in Freezer Bags
Once the mushrooms are frozen solid, transfer them to freezer-safe bags, such as Stasher bags or freezer-safe plastic bags. Squeeze out as much air as possible from the bags before sealing to prevent freezer burn and extend the shelf life. Label the bags with the date of freezing.
Using Frozen Mushrooms
Frozen mushrooms are best used within a year. You can add them directly to hot recipes, such as soups, stews, casseroles, or pasta dishes, without thawing. Alternatively, you can thaw them overnight in the refrigerator before cooking. Remember that frozen mushrooms may have a softer texture and a darker colour, and their nutritional value may be slightly reduced.
