Dehydrating Onions

Dehydrating onions can be a tearful job, so please run your range hood vent (if you have one).

Place your dehydrator as close to the vent hood as possible.

That will help enormously to take the onion odor out of the kitchen and away from your pets sensitive noses and nervous systems – it's poisonous to them!

NOTE: When dehydrating this pungent veggie, you may want to consider dehydrating some garlic at the same time if you've got a spare dehydrator tray or two available!

Don't mix the two with, say, apples, when dehydrating – unless you WANT your APPLES to taste like ONIONS or GARLIC!!

Air Ventilation Warning

You may also wish to have your windows OPEN, or put the A/C on while you're dehydrating onions or garlic ... as the very strong odor can certainly circulate throughout the whole house!

Drying time: between 4-12 hours.

"I noticed that my white onions did not turn as brown as my Vidalia onions, did a little research and found that it might have to do with the sweeter onion which makes sense. I also noticed that the Vidalia seem sweeter dried then fresh which is fine with me.

I am so very happy that I found a great deal on them and dried close to 50lbs of them this spring. I did do many batches outside when I saw that the humidity was very low, with starting them outside in the morning by night the smell was almost gone when I finished them in the home."
