Clean the mushrooms by gently brushing off any dirt or debris. You can also wipe them with a moist paper towel if needed. Remove the stems if desired.

After blanching, pat the mushrooms dry with a clean kitchen towel or paper towel. Arrange them in one layer on a cooking sheet lined with parchment paper.

Place the cooking sheet in the freezer & allow the mushrooms to freeze for about 1 to 2 hours or till they become solid.

4. Storing the Frozen Mushrooms

Transfer the mushrooms to airtight freezer bags or containers once they have completely frozen. Remove any excess air from the bags before sealing them tightly.

Label the bags with the date and contents for easy reference. Store the frozen mushrooms in the freezer for up to 6 months.
