Button mushrooms can be frozen raw, but they may become soggy
Mushrooms are a versatile ingredient with a distinctive earthy, umami flavor and meaty texture. They are highly perishable, with a shelf life of about a week when stored in the refrigerator. However, freezing is an effective way to extend their shelf life. Button mushrooms, which account for over 90% of mushrooms bought in grocery stores, can be frozen raw, but they may become soggy.
Freezing raw button mushrooms is convenient, but it is important to consider their high water content, which can lead to sogginess upon thawing. To freeze button mushrooms raw, start with fresh mushrooms and clean them to remove any dirt. You can wipe them with a damp paper towel, brush them with a pastry brush, or give them a quick rinse, ensuring they are thoroughly dried afterward. Trim the stems, and slice or quarter the mushrooms. Place the prepared mushrooms in a single layer on a lined baking sheet and put them in the freezer. Once frozen, transfer them to freezer-safe bags, removing as much air as possible, and store them for up to six months to a year.
While freezing raw button mushrooms is straightforward, they tend to become mushy when cooked after thawing. This is because they absorb water during the thawing process, resulting in a less desirable texture. Therefore, it is recommended to use raw frozen button mushrooms in dishes where their texture is not a critical factor, such as casseroles, soups, or blended recipes.
To avoid the sogginess issue, it is advisable to cook button mushrooms before freezing. Sautéing or steaming are effective methods to remove moisture and improve their texture and flavor after thawing. To sauté, heat a small amount of oil or butter in a pan over medium heat and cook the mushrooms until fork-tender. Allow them to cool completely, then transfer them to freezer bags for storage. By cooking button mushrooms before freezing, you can better preserve their nutritional value, flavor, and texture, ensuring a more enjoyable dining experience.
In conclusion, button mushrooms can be frozen raw, but they may become soggy due to their high water content. To mitigate this, cooking them before freezing is recommended, especially if you intend to use them in dishes where texture is important. By following the proper preparation and storage methods, you can enjoy the convenience of frozen button mushrooms while maintaining their quality and versatility in your favorite recipes.

Mushrooms can be frozen raw, but they tend to become soggy and mushy when cooked. This is because mushrooms are like sponges and absorb a lot of water. Therefore, it is recommended to cook mushrooms before freezing them. However, if you want to freeze raw button mushrooms, you can follow these steps:
Firstly, trim the stems of the button mushrooms. You can keep small mushrooms whole, but larger mushrooms should be sliced or chopped into uniform pieces.
Next, clean the mushrooms by brushing off any visible dirt or gently rinsing them in cold water. Make sure to dry them thoroughly with a paper towel, as mushrooms absorb moisture easily.
Then, place the trimmed and cleaned mushrooms into a freezer bag. Squeeze out as much air as possible from the bag before sealing it. Label the bag with the date of freezing, as frozen mushrooms can last for up to 6 to 12 months in the freezer.
Finally, place the freezer bag with the button mushrooms into the freezer. It is best to lay the bag horizontally and ensure it is not bumped, so the mushrooms stay loose and frozen in a single layer.
By following these steps, you can successfully freeze raw button mushrooms and extend their shelf life. However, note that frozen raw mushrooms are best suited for cooked dishes like soups, casseroles, or pasta, where their texture is less important.
