Mushrooms are a versatile ingredient, but they can quickly spoil. Freezing them is a great way to extend their shelf life and reduce food waste. While freezing can negatively affect their texture and some nutrients, it is still a helpful preservation method. To freeze sliced mushrooms, they must be cleaned, cooked, cooled, and then placed in a freezer bag. This process ensures they retain their flavour and texture as much as possible.

What You'll Learn
Freezing sliced mushrooms extends shelf life
Mushrooms are highly perishable and only last about a week in the refrigerator. However, freezing sliced mushrooms is an effective way to extend their shelf life. Freezing mushrooms can reduce food waste and help you take advantage of sales or leftovers.
Before freezing, clean the mushrooms by brushing off any visible dirt or rinsing them in cold water, ensuring they are thoroughly dried. Trim any woody parts from the stems, then slice the mushrooms into uniform pieces. Smaller mushrooms can be left whole.
To prepare the mushrooms for freezing, you can steam or sauté them. To steam, soak the mushrooms in a bowl of water with lemon juice for 10 minutes to prevent discolouration, then steam for 3-5 minutes. Transfer the mushrooms to an ice water bath, then strain and pat them dry. To sauté, cook the mushrooms in a pan with a small amount of oil or butter over medium heat until soft and the pan is mostly dry. Allow the mushrooms to cool.
Once the mushrooms are cooled, spread them on a parchment-lined baking sheet and place them in the freezer. Once frozen, transfer the mushrooms to a freezer-safe container or bag, removing as much air as possible before sealing and labelling. Frozen mushrooms can be stored for up to a year and should be used in cooked dishes, as freezing affects their texture and makes them unpleasant to eat raw.

Sliced mushrooms can be frozen raw or cooked
To freeze cooked sliced mushrooms, prepare the mushrooms by cleaning and slicing them as mentioned above. Then, cook the mushrooms by sautéing or steaming them. To sauté the mushrooms, heat a small amount of oil or butter in a pan over medium heat and cook the mushrooms until they are soft. To steam the mushrooms, soak them in a bowl of water with lemon juice for 10 minutes, then place them in a steamer basket over a pot of boiling water for 3-5 minutes. After cooking, allow the mushrooms to cool to room temperature, then transfer them to a freezer bag or container, removing as much air as possible before sealing and labelling. Frozen cooked mushrooms can be added directly to dishes or thawed overnight in the fridge.
Freezing mushrooms is a great way to extend their shelf life, reduce food waste, and have them on hand for recipes throughout the year. However, it's important to note that freezing can affect the texture and flavour of mushrooms, making them soggy or mushy. For this reason, it is generally recommended to cook mushrooms before freezing, as this removes some of the moisture and improves their texture and flavour. Additionally, mushrooms are a good source of nutrients, and while freezing does not affect their calorie, fibre, or mineral content, it can reduce the content of certain water-soluble vitamins.

Cooking sliced mushrooms before freezing improves texture
Mushrooms are highly perishable and only last about a week in the refrigerator. Freezing them is a great way to extend their shelf life and reduce food waste. However, freezing changes the structure and texture of mushrooms, and they can become soggy and mushy. Cooking sliced mushrooms before freezing improves their texture and flavour.
Mushrooms hold a good amount of water, and freezing them fresh can result in an unpleasant, mushy texture. Cooking them before freezing removes some of this moisture, improving their texture and making them more enjoyable to eat. Sliced mushrooms can be cooked by sautéing or steaming before freezing.
To sauté sliced mushrooms, heat a small amount of oil or butter in a pan over medium heat. Add the mushrooms and cook until they are soft and the pan is mostly dry. The mushrooms will release their moisture during cooking, which will then evaporate. It is important not to overcrowd the pan, as this can prevent the mushrooms from cooking properly.
Steaming is another option for cooking sliced mushrooms before freezing. To steam, place the mushrooms in a steamer basket over a pot of boiling water and cook for 3-5 minutes. Then, transfer the mushrooms to an ice water bath for the same amount of time, strain, and pat them dry.
Whether sautéed or steamed, it is important to allow the mushrooms to cool completely before transferring them to a freezer-safe container or bag. Remove as much air as possible, seal, and label the container or bag. Frozen cooked mushrooms can be stored in the freezer for up to a year and can be added directly to cooked dishes, such as stews, casseroles, pasta bakes, or stir-fries.

Blanching sliced mushrooms before freezing improves safety
Mushrooms are highly perishable and only last about a week in the refrigerator. Freezing them is a great way to extend their shelf life and reduce food waste. While freezing mushrooms is a simple process, there are certain steps you can take to ensure optimal flavour, texture, and safety.
Blanching sliced mushrooms before freezing is an effective way to improve their safety. Mushrooms are susceptible to bacterial growth, and blanching can help address this issue. The process involves briefly heating the mushrooms, which destroys enzymes that contribute to spoilage. This not only extends their shelf life but also improves food safety by inactivating common foodborne pathogens such as Listeria and Salmonella.
To blanch sliced mushrooms, start by soaking them in a mixture of water and lemon juice to prevent discolouration. Then, steam the mushrooms for a few minutes, followed by an ice bath to stop the cooking process. This process not only improves safety but also helps retain their flavour and texture.
After blanching, it is important to dry the mushrooms thoroughly before freezing. Pat them dry with a towel and ensure they are completely cool. Then, transfer the mushrooms to a single layer on a parchment-lined baking sheet and place them in the freezer. Once frozen, transfer the mushrooms to a freezer-safe bag or container, removing as much air as possible before sealing and labelling.
By blanching sliced mushrooms before freezing, you can improve their safety, extend their shelf life, and preserve their flavour and texture. This process ensures that you can enjoy mushrooms year-round while minimising the risk of foodborne illnesses.

Frozen sliced mushrooms are best suited for cooked dishes
Mushrooms are highly perishable, lasting only about a week in the refrigerator. Freezing them is a great way to extend their shelf life and reduce food waste. Frozen sliced mushrooms are best suited for cooked dishes, as freezing changes their structure and texture, making them less pleasant to eat raw.
When preparing mushrooms for freezing, it is important to start with fresh, whole mushrooms and avoid any that are shrivelled or slimy. Clean the mushrooms by brushing off any visible dirt or rinsing them gently in cold water, then pat them dry thoroughly. Trim the stems, and cut larger mushrooms into uniform slices or quarters. Smaller mushrooms can be left whole.
Before freezing, it is recommended to cook the sliced mushrooms to improve their texture and flavour. Sautéing or steaming are the best methods for cooking mushrooms before freezing. To sauté, heat a small amount of oil or butter in a pan over medium heat and cook the mushrooms until they are fork-tender and the pan is mostly dry. To steam the mushrooms, soak them in a bowl of water with lemon juice for 10 minutes to prevent discolouration, then steam for 3-5 minutes. After cooking, allow the mushrooms to cool to room temperature before transferring them to a freezer bag or container.
When ready to use, frozen sliced mushrooms can be added directly to cooked dishes, such as stews, casseroles, pasta bakes, or stir-fries. They can also be thawed overnight in the refrigerator before cooking, but this is not necessary. Frozen mushrooms may lose some of their nutritional value over time, particularly in terms of water-soluble vitamins like riboflavin, niacin, and folate. However, freezing does not affect their calorie, fibre, or mineral content.
