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. The end result has a slightly different texture than store-bought onion powder, but a much more onion-packed flavor.
Onion Powder on the Nesco Snackmaster ProMy first use of my onion powder was in a rub for rotisserie-style chicken. You can definitely tell the difference between onion powder made on the Nesco Snackmaster Pro and the stuff in a jar. Wow!

After drying the onions for 24 hours I ground them using a blade coffee grinder (not the burr grinder). Not all of the onion pieces would go thru the grinder (they were still a bit moist) so I returned them to the dehydrator for just a bit.

The final product went into Mason jars with lids and then vacuum-sealed using a jar attachment for a vacuum sealer. You just have to remember that after you open the jar to remove some of the powder you’ll need to re-seal it. No big deal and well worth the effort.

Bell pepper powder is also great when made on your Nesco Snackmaster Pro.

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.

  • 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.
