Ingredients

  • Onions

Instructions

To dry the onions:

  • Prepare your onions by removing the skins, trimming the ends, and slicing into even sized pieces. 
  • Separate the onion segments and spread them out evenly on your dehydrator trays in a single layer.
  • Set the temperature of the dehydrator to 125˚F and dry for 3-9 hours. The timing will depend on the size of your onion pieces and moisture content. The dehydrated onions should be crisp and snap when your break them.
  • Let the dried onion pieces cool, crush into onion flakes, and package into airtight glass containers or process further into dried onion flakes and onion powder.

To make minced dried onions and onion powder:

  • Place the dried onion flakes into the bowl of a spice grinder and pulse until you have a mixture of flakes and powder.
  • Use a fine mesh strainer over parchment paper to filter out the onion flakes from the onion powder.

To store the dehydrated onions:

  • Store the dehydrated onion flakes, minced onions, and onion powder in separate jars. Label, date, and store in a cool area away from direct light.
  • Check the jars in a few days to be sure there isn't any moisture accumulating on the glass. If you find moisture, dehydrate again and repackage into fresh jars.
