Onion Powder on the Nesco Snackmaster Pro

Onions were on sale here last week. I hate passing up on a deal, so bought a few nice big onions, and proceeded to make homemade onion powder using my Nesco Snackmaster Pro.

  • Onions sliced or chopped thin (try to make the pieces consistent in size)


  • Place the onions into the dehydrator. Make sure they do not touch or overlap.
  • Dry at 165 F for 18-24 hours, or until the onions are crispy. Smaller pieces will take less time. I cut mine big, so they took the full 24 hours.
  • Let cool completely then grind using a blender or blade coffee grinder (not a burr grinder).
  • Keep in an air-right container. I place mine in a Mason jar, cover it, then use a vacuum-sealer attachment specifically for jars to remove all of the air.


Unless you cut your onions into large pieces, grab a few extra trays for the Nesco Snackmaster Pro. They make drying vegetables and herbs much easier.
