How To Dehydrate Green Onions using a straightforward method that keeps their flavor and cuts down on kitchen waste. Use them in soups, stews, dips, or grind into onion powder for seasoning blends.
Spread the pieces over each dehydrator tray in a single layer. Load the trays into the appliance.
Turn the dehydrator on and set the temperature to 105 °F
After 2 hours rotate the trays and check to see how dry the green onion pieces are.
Every couple of hours check for doneness. The green tops will dry in about 6 hours total. It will take about another 4 to 6 hours for the thicker white pieces to dry completely.
Once done allow to cool completely before storing.
Transfer to mason jars, air tight containers or mylar bags.
Dehydrated onions will last a year or longer depending on how well you store them.
Recipe Expert Tips
Dried green onions can be used the same way fresh scallions or green onions can be used.
Cut the onion parts separately.
If using a dehydrator that does not have a temperature control check for doneness every hour. These models usually run at about 165 degrees. Read the manufacturers guide that came with it. Anything you are dehydrating will be done much more quickly because of the higher temperature.
