How to Dry Mushrooms in the Oven

  1. Clean and Slice

  2. Arrange on a Tray

    Place a piece of parchment paper on the baking tray for ease of cleaning then place the oven safe rack on top. Place the mushrooms on top of the rack without overlapping the slices.
    If you don’t have a rack you can place the slices directly on the parchment paper but they will need to be turned over halfway through the drying time.

    Place in a preheated oven at 212ºF (100ºC) for 2 hours. The slices should be thin and leathery. Take out of the oven then leave to cool for 2 hours or overnight on the rack.

  1. a few of my mushrooms are still a little moist. what do I do with them? maybe I sliced those a little too thick.

    1. You can either leave them on a rack to air dry in a spot which has good air circulation such as near an outside door for a few days or place them back in the oven preheated to 212ºF (100ºC). Check every 10 to 15 minutes until they feel dry.
