Dried Onions: When Dehydration is Complete
When your onions are done dehydrating, allow them to cool completely before you do anything else. Once they’re cool, dump them loosely in a bowl, and cover them with a clean kitchen cloth. Set the bowl aside, out of direct sun light, for a couple of weeks. Every day, shake the onions gently and look carefully for drops of condensation that might have gathered on the inside of the bowl. If you find any water droplets, it means they need to be dried more, so back into the oven or dehydrator they must go. If you find no moisture, you can package the onions up after 12 days or so.
Package your onions into small batches – Vacuum sealing (Amazon) is best. Store your dried vegetables, from onions to dried carrots, bell peppers, and dehydrated tomatoes, in a cool, dry, and dark place like the freezer for longest shelf life.
Using Dried Onions
Use these ratios for your onions, when cooking:
1 teaspoon dried onion = 1 small onion
1 to 2 tablespoons dried onion = 1 medium onion
1/4 cup dried onion = 1 cup chopped fresh onion
Don’t like the texture of re-hydrated onion in your food? Then make onion powder! Grind the dried pieces of onion into a powder with either a mortar and pestle, food processor, or manual grinder. Each tablespoon of dried onion will grind down into about a teaspoon of onion powder. A half teaspoon of onion powder is the equivalent of a quarter cup fresh onion.
Onion powder can be used as-is or mixed with other ingredients like salt, herbs or seasonings. I like it in a little shaker to sprinkle onto meats and into sauces and salad dressings.
Now that you know how simple the process of dehydrating onion pieces is, you can tackle it with confidence.

We used to dry onions every year. Mom has an electric dehydrator and we just cut the onions into thin slices… didn’t bother separating them, just laid the slices on the trays. Once dry we stored them in clean dry canning jars. A quick whirl in the food processor chopped them if we wanted chopped.
They are so fantastic on homemade rolls… Just roll the tops of your uncooked rolls in the dried onion pieces, then bake. You’ll have amazing onion rolls for sandwiches.
And did you know that dried onions are sweet? We ate them for snacks!

I’m from a onion farm village and the onion use to come in number year and i want the process and how to dehydrat it grind in to powder
I just got a dehydrator and I’m woriendng if your toddler has any trouble chewing these? One of the main reasons I got a dehydrator was to make healthy snacks for my little one (14 months) but after my first batch I’m concerned about her ability to chew some of the dehydrated foods. What has your experience been?

As far as littles and dehydrated foods. i am mother, foster mom, grand-ma and great grand-ma to 24 wonderful individuals. So based on my experiences; littles will knaw, suck and masticate any number of food stuffs and non-food stuffs. Variety is key, the textures and flavors are building blocks for future good health. As always be vigilant, to limit and avoid chocking hazards. Happy gardening and preserving. Just a note, my group has tasted, tested and proofed such wonders as kale chips, jicama w/ lime chips, trail mix of dryed beets, kolhirabi, carrots, eggplant, and squash. I make jam, jelly and conserves with no to very little sweetners, so far cantaloup marmalade and fruit/veggie butter is a hit.

I am from Africa where we are blessed with lots of sunshine so I always have sun-dried onion flakes.

Do the onions leave a lingering onion flavor on the plastic dehydrator racks? I want to dry fruits with the same racks and don’t want oniony fruit.
Thanks for your response!
