Onionssliced or chopped thin (try to make the pieces consistent in size)
Instructions
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.
