  • Slice garlic cloves into thin, uniform slices. Uniform slices will dry at the same rate and help to avoid burning some slices while you wait for others to be ready.

  • Lay garlic cloves on your dehydrator trays with room between them for air to flow. Do not overlap.

  • Set the dehydrator on a low temperature (95 degrees) and set in a place where there is good air circulation (a porch with open windows works great)
  • Check the garlic after 10-12 hours. When it is fully dried, the slices should break in half with a crunch instead of bending. It make take up to 15 hours to reach this point.
  • Once dry, use a spice grinder, coffee grinder (used for spices) or mortar and pestle to grind the garlic in batches.

  • Sift the ground garlic through a fine meshed strainer to keep larger chunks out of your garlic powder. This will result in a fine powder. Larger pieces may have a higher moisture content and cause the powder to clump up; set these aside and use them sooner in cooking.
  • Place garlic powder into a spice jar or other glass container that seals out air and moisture (or a ziploc bag).
