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.

Step 1

Choose young immature onions with good color.

Step 2

Slice the onions into rings about 1/8 inch thick with a knife.

Step 3

Place the onions on drying trays on one layer. Leave a little space between the pieces.

Step 4

Place the trays in the dehydrator. Turn the dehydrator to 140 degrees Fahrenheit.

Step 5

Leave the onions in for 3 to 6 hours. Turn the onions over at the halfway mark.

Step 6

Turn down heat to 130 degrees Fahrenheit for the last hour of dehydration.

Step 7

Remove onion slices from dehydrator and let them cool.

Step 8

Store the onions in containers and keep in a cool and dry place. Another option is to put the containers in the freezer.
