Drying vegetables is an easy and effective way to preserve them. By removing the moisture, vegetables last longer and have a longer shelf life. A wide range of vegetables are suitable for dehydration, including onions. Onions play an important role in many recipes. Although dry onions don’t have as pungent a taste or aroma as fresh onions, they still provide flavor for dishes. Dehydrators are effective for drying and preserving.
Choose young immature onions with good color.
Slice the onions into rings about 1/8 inch thick with a knife.
Place the onions on drying trays on one layer. Leave a little space between the pieces.
Place the trays in the dehydrator. Turn the dehydrator to 140 degrees Fahrenheit.
Leave the onions in for 3 to 6 hours. Turn the onions over at the halfway mark.
Turn down heat to 130 degrees Fahrenheit for the last hour of dehydration.
Remove onion slices from dehydrator and let them cool.
Store the onions in containers and keep in a cool and dry place. Another option is to put the containers in the freezer.
