Onions are such a versatile vegetable. They are cheap and add so much flavor, just about any savory recipe is better when onions are added. Dehydrating onions is quick and easy.
Begin by chopping your onions to the desired size. I usually do large flakes so the pieces don’t fall through the holes on my dehydrator but you could always mince them. Try to remove the thin pieces of skin that clings between the layers. (You can get a dehydrator like mine here)
Dunk your onion pieces into boiling water for about 30 seconds to a minute. They will turn slightly translucent when they are ready and they will be softer. Put them in a strainer and run cold water over them to stop the cooking process.
Pat the pieces dry with some paper towel and remove any extra bits of the skin (which will now be mushy and easy to remove). Arrange the pieces in a single layer on your dehydrator and turn it on.
My dehydrator doesn’t have a temperature control so I just let it run for about 5 hours to have the onions as dry as I need them. They end up paper thin. Now here’s a recipe you can use your onions for:
Dry Onion Soup Mix
1 cup dehydrated onion flakes
1/3 c bouillon
1/4 tsp sugar
1 tsp parsley
Store the ingredients in an airtight jar until ready for use. I also like to throw in some other dehydrated veggies (carrots, garlic, celery and whatever else catches your fancy.) To make into soup, add 4 c of water, or for dip, add to a tub of sour cream.
