How to Make Onion Powder Instructions
You may start with your favorite onion (mine is the sweet onion, or walla walla) or choose a variety of onions for a wonderful flavor. You can even throw in some chopped green onion too.
If you have a cold smoker, try smoking the onion which brings more awesomeness to anything you add it to.
Chop the amount of onion you want to dry, then spread evenly on a baking sheet and place in a 150 degree oven. Of course, a food dehydrator is perfect for this. The onions are dry and ready when you can easily crumble them in your hand.
Allow to cool and then grind in a food processor, mortar and pestle, spice mill or coffee grinder until you reach the desired consistency your looking for.
Store in an airtight container in a cool and dry place, or freeze for long-time storage.
