Mushrooms are a versatile ingredient, adding a savoury flavour and meaty texture to dishes, especially vegetarian or vegan meals. But how do you make them last longer? Freezing mushrooms can increase their shelf life and reduce food waste. Mushrooms can be frozen raw, but they tend to become soggy and mushy when cooked. To avoid this, it's best to cook them before freezing. Sautéing or steaming mushrooms before flash freezing them can help to preserve their texture, flavour, and nutrients. Frozen mushrooms are best suited for cooked dishes, such as soups, casseroles, pasta, and stir-fries.

Preparing mushrooms for freezing
Cleaning and Trimming
Start by selecting fresh mushrooms. Avoid any that appear shrivelled, slimy, or have dark spots, as these will not freeze well. Clean the mushrooms using a damp paper towel or brush to remove any dirt. You can also quickly rinse them with water, but ensure they are thoroughly dried before freezing. Trim the stems, removing any dried-out parts, and slice or chop the mushrooms into your desired size. Smaller mushrooms can be left whole.
Cooking
Cooking mushrooms before freezing is recommended to improve their texture and flavour. Sautéing is a popular method, where you cook the mushrooms in a pan with a small amount of oil or butter over medium to high heat for about five minutes, or until they are fork-tender and most of the liquid has evaporated. You can also steam mushrooms by soaking them in a bowl with water and a teaspoon of lemon juice, then steaming them for 3-5 minutes.
Flash Freezing
After cooking, allow the mushrooms to cool completely. Spread the cooled mushrooms 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.
Storage
Once the mushrooms are frozen solid, transfer them to freezer bags or containers. Remove as much air as possible before sealing to prevent freezer burn. Label the bags with the date, and store them in the freezer for up to six months to a year.
Cooking with Frozen Mushrooms
Frozen mushrooms are best suited for cooked dishes, such as soups, casseroles, pasta dishes, and stir-fries. You can add them directly to your recipes without thawing, but be sure to increase the cooking time to ensure they are heated through and any excess moisture evaporates.

Cooking methods before freezing
Mushrooms can be frozen, and there are several cooking methods that can be employed before freezing them. Here are some common methods to prepare mushrooms for freezing:
Sautéing or Pan-Frying:
- Clean and slice the mushrooms to the desired thickness.
- Heat a pan over medium-high heat and add a small amount of butter or oil.
- Sauté the mushrooms in batches to avoid overcrowding the pan. Stir frequently until they are lightly browned and softened.
- Spread the sautéed mushrooms in a single layer on a baking sheet and place them in the freezer until completely frozen.
- Transfer the frozen mushrooms to an airtight container or freezer bag for longer-term storage.
You may want to see also Freezing mushrooms can increase their shelf life and reduce food waste. However, freezing may negatively affect their nutrient composition, texture, and flavour. Mushrooms have a high water content, so they can become soggy and mushy when frozen. Here are some methods to freeze them: Cleaning and Preparation Before freezing, wipe the mushrooms with a damp paper towel to remove any dirt. Avoid washing the mushrooms as they can become soggy. Trim off any dried-out parts of the stems. Remove the stems entirely from portobello, chanterelle, and shiitake mushrooms. Smaller mushrooms can be kept whole, but most other mushrooms should be sliced or quartered. Sautéing Sautéing is a recommended method to prepare mushrooms before freezing. Heat a small amount of oil or butter in a pan over medium to high heat. Add the mushrooms and cook for about five minutes, or until they are fork-tender and the pan is mostly dry. Allow the mushrooms to cool completely before freezing. Steaming Another option is to steam the mushrooms before freezing. Start by soaking them in a bowl with water and a teaspoon of lemon juice to prevent discolouration. Then, place the mushrooms in a steamer basket over boiling water and steam for 3-5 minutes until cooked. Allow them to cool completely before freezing. Flash Freezing After sautéing or steaming, spread the cooled mushrooms onto a parchment paper-lined baking sheet. Place the sheet in the freezer for about an hour, or until the mushrooms are frozen solid. Then, transfer the frozen mushrooms to labelled resealable freezer bags, removing as much air as possible. Raw Freezing Mushrooms can also be frozen raw, but they may become mushy when cooked. Simply trim their stems and place them in a single layer on a lined baking sheet. Freeze for 1-2 hours until solid, then transfer to freezer bags, removing as much air as possible before sealing. You may want to see also Preparation Start by choosing fresh mushrooms that look and smell pleasant. Avoid any that are dry, shrivelled, darkened, mouldy, or give off a bad odour. You can keep small mushrooms whole, but most mushrooms should be sliced or quartered. It is best to trim off any dried-out parts of the stems or remove the stems entirely from larger mushrooms such as portobello, chanterelle, and shiitake. Cleaning Wipe the mushrooms with a damp paper towel, or brush them with a pastry brush, to remove any dirt. Avoid rinsing them with water, as this can make them soggy when cooked. Mushrooms absorb moisture easily, so ensure they are dried thoroughly. Cooking Cooking mushrooms before freezing is recommended to preserve their flavour and texture. Sautéing them in a pan with a small amount of oil or butter for about five minutes is a quick and easy way to dehydrate them. You can also steam mushrooms by soaking them in a bowl with water and lemon juice, then steaming them in a basket for 3-5 minutes. Freezing Once the mushrooms are cooked and cooled, spread them onto a parchment paper-lined baking sheet and place them in the freezer for about an hour, or until they are frozen solid. Then, transfer the frozen mushrooms to freezer bags. Remove as much air as possible from the bags before sealing them tightly. Storage Label the bags and store them in the freezer for up to six months to a year. Frozen mushrooms are best suited for cooked dishes, such as soups, casseroles, pasta, and stir-fries. They can be added directly to recipes without thawing, but you may need to increase the cooking time to ensure they are heated through and any excess moisture is released. You may want to see also Mushrooms can be frozen raw, but they tend to become soggy and mushy when cooked. This is because mushrooms are like tiny sponges and absorb a lot of water. Therefore, it is better to cook them slightly before freezing. Sautéing is a good option as it uses a small amount of fat and a high temperature to quickly dry out the mushrooms. Steam blanching is another option, which involves soaking the mushrooms in lemon juice and water to prevent discolouration, then steaming them for 3-5 minutes. Once the mushrooms are cooked, allow them to cool, then spread them out on a lined baking sheet and place them in the freezer. Once frozen, transfer the mushrooms to freezer bags, removing as much air as possible. Label the bags and store in the freezer for up to 6 months. Frozen mushrooms are best suited to hot recipes like soups, casseroles, pasta, risotto, and stir-fries. They can be added straight to the dish without thawing, but the cooking time may need to be increased to allow the mushrooms to fully cook and release any excess moisture. If using frozen mushrooms in a cold dish, it is best to thaw them first by transferring them to the refrigerator overnight. You may want to see also Yes, you can freeze mushrooms. Start with fresh mushrooms. Clean them with a damp paper towel or brush to remove dirt. Trim the stems and slice the mushrooms.
