You can freeze raw, blanched or cooked mushrooms depending on your use:

  • Raw : quick, but spongier texture when defrosted — ideal for stews or pan-fried dishes 🥘.
  • Blanched : preserves color, firmness, and flavor better — perfect for omelets or quiches 🍳.
  • Cooked (sautéed): ready to use, intense flavor, no water released during cooking — great for saving time 🔥.

Tip: Blanching is best to keep mushrooms looking nice, and remember to prepare them well before freezing (gently cleaning, slicing). Use tightly sealed freezer bags to avoid frost ❄️.

Did you know? Button mushrooms freeze very well, but all fresh mushrooms can follow these instructions: porcini, chanterelles, oyster mushrooms, shiitake mushrooms... For morels, always cook them before freezing (never raw) 🧑‍🍳!

How to freeze mushrooms step by step?

  1. Prepare the mushrooms : brush or dry them gently (avoid soaking them in water). Trim the earthy stems and slice as needed.
  2. Choose your method :
    • Raw : Arrange them in a single layer on a baking sheet, freeze for 2 hours then transfer to a freezer bag.
    • Blanched : immerse them for 2-3 minutes in boiling salted water, refresh in iced water, drain and dry well before freezing.
    • Cooked : Sauté them in a pan in a little oil or butter until they release their water. Let them cool before freezing.
  3. Pack carefully : Use airtight bags or boxes, remove as much air as possible. Indicate the date and variety ✍️.
  4. Store in the freezer : Store flat for optimal storage. Mushrooms can be easily stored for several months without any problems.
Practical tip: For hassle-free cooking, make ready-to-use portions (for example, for an autumn stir-fry or a homemade pizza!). And hey presto, guaranteed time savings ⏱️.
