Step 1

Prepare your onions by removing the skins, trimming the ends, and slicing into even sized pieces.

Step 2

Separate the onion segments and spread them out evenly on your dehydrator trays in a single layer.

Step 3

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.

Step 4

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.

Step 5

Place the dried onion flakes into the bowl of a spice grinder and pulse until you have a mixture of flakes and powder.

Step 6

Use a fine mesh strainer over parchment paper to filter out the onion flakes from the onion powder.

Step 7

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.

Step 8

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.
