  • Blueberries or fresh fruit of choice
  • Water for rinsing


  • Rinse berries and remove any twigs, leaves, etc.
  • Check berries by either freezing for a few hours, poking each berry with a pin, needle or paperclip, or quickly blanching in hot water.
  • After you've checked your berries, spread them out on your dehydrating trays. Try to put berries of similar size on the same trays.
  • For sticky berries or fruit, I highly recommend the silicone mats for easy clean up. You want to the berries or fruit to be evenly spaced so they dehydrate at the same rate.
  • Turn on your dehydrator to 135 degrees Fahrenheit or the fruit setting if it has one.
  • Check your berries or fruit after 12 hours and rotate your trays. My top tray dehydrates a tad faster than the bottom one, especially when I've got all four stacked at once.
  • Even with checking, berries take quite a while to fully dehydrate. My cherries took 28  hours. My small blueberries were done at about 24 hours, where as the larger ones took 36 hours.
  • Your fruit is done when it's shriveled and slightly tacky/sticky. You don't want it to be rock hard but neither do you want it to have too much moisture that it could mold. A simple trick is to put a small test amount of still WARM fruit straight from the dehydrator in a sealed glass or plastic bag. If after a few minutes you see any condensation inside, put the fruit back and dehydrate longer.
  • Store dehydrated berries in an airtight container in a dark cool place for optimal shelf life. Use in homemade breads, muffins, granola, candy, or just plain old eating! Be warned, they're kind of addicting.
