Mushrooms are mostly water and if you freeze them raw, they tend to become mushy. This consistency works okay in soups, casseroles, and stews, but it’s not the best result you can achieve. If you prepare the mushrooms first, either using traditional steam blanching or sautéing, you’ll be able to use those mushrooms in more ways in the kitchen.
