How To Dehydrate Mushrooms

How to dehydrate fresh edible mushrooms for long term storage is an easy way to preserve mushroom so you can enjoy fresh mushroom recipes anytime you want.

Dehydrated mushrooms will last 6 month to a year when stored in an airtight container.



  • 4 to 5 lbs fresh mushrooms, washed, rinsed and drained well.


  1. 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.
  2. Break the stem off of each mushroom and slice into 1/4 to 1/2 inch thick slices with a sharp knife.
  3. Place the sliced mushrooms on a dehydrator tray that has been lined with a plastic mesh liner for your dehydrator.
  4. Continue slicing and filling the dehydrator trays until you run out of trays or mushrooms.
  5. Stack the trays on the dehydrator base and place the lid on.
  6. Turn the dehydrator on.
  7. The amoount of time it will take will depend on the temp of the dehydrator and the thickness of the slices.
  8. Check the mushrooms after and hour and flip them over for even drying. Check the mushroom slices every hour.
  9. If using a dehydrator like the model I am using it will take about 4 to 4 1/2 hours to dehydrate 1/4 inch thick slices.
  10. Dehydrating at a lower temp will mean it will take longer.
  11. As the mushroom slices dry remove them from the dehydrator and allow to cool on the tray or a paper towel.
  12. Store dried mushroom slices in an airtight glass container.


  • A sharp knife is recommended to slice the fresh mushrooms. I tried using a mandoline 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.
