Pure, flavorful homemade onion power


  • One medium yellow onion


  1. Preheat oven to 150 degrees F or 200 degrees if that is the lowest your oven will go
  2. Peel and thinly slice onion
  3. Arrange on a parchment lined baking sheet and bake for at least two hours until the onion is dehydrated. Two hours is best but the key is making sure the pieces are crumbly dry. Let cool.
  4. Grind in a spice grinder, crush with a mortar and pestle or mash with the back of a spoon.
