Yes, you can freeze mushrooms, but it is best to cook them first, by sauteing or steaming, because raw mushrooms turn watery and mushy when frozen and thawed. Cool the cooked mushrooms, then freeze them in portions for up to 9 to 12 months. Use them straight from frozen in cooked dishes.
Freeze mushrooms cooked (sauteed or steamed), not raw. They keep 9 to 12 months; use from frozen.
How to Freeze Mushrooms
- Clean and slice the mushrooms, then saute or steam them until just cooked.
- Cool them fully, then portion into freezer bags or containers.
- Label and use within 9 to 12 months.
- Add them straight from frozen to soups, sauces and stir-fries.
Why Cook Them First
Raw mushrooms are high in water, so freezing them raw makes them soggy and rubbery once thawed. Cooking first drives off moisture and preserves a better texture. For fresh storage, see how to store mushrooms. Freeze portions in an airtight container.
