Tired of forking over big bucks for a little jar of onion powder? Here's how to make it yourself and save:


  • Onions


1. Peel and finely chop your onions.

2. Then, spread the onion pieces out on a tray and heat in a 150 degree oven or in a food dehydrator until dry.

Tip: The onions are dry when you can easily crumble the chopped pieces in your hand.

3. Allow the onions to cool. Then, grind with a coffee grinder, spice mill, food processor or mortar and pestle until you reach your desired consistency.

4. Store your finished onion powder in an air-tight container in a cool, dry spot or freeze.
