Can You Freeze Mushrooms: Cooked First
Yes—you can freeze mushrooms, but they keep a firmer, more useful texture when cleaned, sliced, cooked, cooled, and packed airtight before freezing. Raw mushrooms can also be frozen, according to Love Food Hate Waste, but thawed mushrooms are usually best in soups, sauces, casseroles, and other cooked dishes rather than fresh salads. Store for up to 3 months.
