  • Rinse whole mushrooms well under cold running water. Gently scrub any visible dirt away with out damaging the mushroom. Pat dry with paper towels if needed.
  • Break the stem off of each mushroom and slice into ¼ to ½ inch thick slices with a sharp knife.
  • Place the sliced mushrooms on a dehydrator tray that has been lined with a plastic mesh liner for your dehydrator.
  • Continue slicing and filling the dehydrator trays until you run out of trays or mushrooms.
  • Stack the trays on the dehydrator base and place the lid on.
  • Turn the dehydrator on.
  • The amount of time it will take will depend on the temp of the dehydrator and the thickness of the slices.
  • Check the mushrooms after and hour and flip them over for even drying. Check the mushroom slices every hour.
  • If using a dehydrator like the model I am using it will take about 4 to 4 ½ hours to dehydrate ¼ inch thick slices. Dehydrating at a lower temp will mean it will take longer.
  • As the mushroom slices dry remove them from the dehydrator and allow to cool on the tray or a paper towel.
  • Store dried mushroom slices in an airtight glass container.


  • A sharp knife is recommended to slice the fresh mushrooms. I tried using a mandolin but because mushrooms are so fragile I couldn't get a clean slice.
  • 4 to 5 lbs. of fresh mushrooms will fit in 2 to 3 quart size canning jars.
  • Serving size is ¼ cup of dried mushroom slices.
  • Love mushroom jerky? You can use the dehydrator to make amazing mushroom jerky packed full of umami flavor.
