Dehydrating onions is easy to do and it doesn’t take much time if you have the right tools. We try to purchase onions while they are on sale at the grocery store or at the farmers market. Of course, you can always grow your own onions as well.
When dehydrating onions you will need: fresh whole onions (we

Uniform pieces are essential for successful, even drying. If all the pieces are not uniformly dry, the onions can mold during storage.

Always follow the instructions that came with the dehydrator for dehydrating times. You want to dehydrate the onions until there is no moisture in it and it snaps clean when you break it in your fingers. Return all your dehydrated chopped onion into the medium
