This is one of the easiest vegetables you can dehydrate and use when you need a little green onion in a recipe. It’s a win-win, I promise.

How To Dehydrate Green Onions

Step One

Wash the green onions, and cut the root off, and discard. Remove any pieces of the green sections that appear at all damaged. We want to dehydrate only the best green onions and scallions. I set my Excalibur Dehydrator at 95 degrees.

Step Two

Now you chop the green onions into small uniform pieces. They are about 3/8 inches in size. I actually kept the green onions and scallions separated.

How To Condition Your Fruit or Vegetables

If you live where it is HUMID: “To condition the fruit, take the dried fruit that has cooled and pack it loosely in plastic or glass jars. Seal the containers and let them stand for 7 to 10 days. The excess moisture in some pieces will be absorbed by the drier pieces. Shake the jars daily to separate the pieces and check the moisture condensation.” https://nchfp.uga.edu/how/dry/pack_store.html

I live in the DRY DESERT: I set my fruit and vegetables on my countertop for 5-7 days. Ten days is even better to make sure everything is dry before using your FoodSaver unit.

Step Seven

I use my FoodSaver to seal these for my pantry. I do not use oxygen absorbers because I will put the dehydrated items to use in recipes within one year.

Being a Master Canner Preserver I only preserve what I can use within 12 months. Here are the accessory hose and white sealers I use with my FoodSaver: FoodSaver Wide-Mouth/Regular-Mouth

Final Word

This post is part of my ongoing series I call “preserving our food” information to fill our pantry. If we learn how to dehydrate onions or scallions, we can prepare so many meals at home.

I strongly recommend that we all must learn to pressure can, water bath, and dehydrate our food, at the very least.

Of course, having a garden goes hand in hand in being self-reliant. We can do this, one step at a time. Please teach your family how to preserve their bounty. May God bless this world, Linda

  1. Your post is so timely. Here in Arizona, I grow L’itoi onions that are multipliers, a nice spicy green onion variety. Once you plant them, you never have to plant again! Don’t you love it? I always have green onions to share with others. But now since I have many in the garden, I think I will dehydrate some today and make the powder to add to recipes. I use green onions in so many things and you mentioned some uses I hadn’t thought of such as deviled eggs. Thanks for this valuable how-to!!!

  2. I just read your recipe on honey baked chicken which you sprinkled chopped green onions over and now I am reading how to dehydrate them.

    I must say, I did not realize that the green stalks or shoots or called scallions. I thought that it was just another name for green onions. I have cut the root ends off and very short as you did in the photo and I planted them in a small pot and they grew immediately. They reached about 6 inches and then they suddenly disappeared. I looked down at Logan (A Belgian Malinois I used to have) who came up to my side. He looked at the little pot and looked up at me. I noticed that the dog had a happy look on his face…. and it was then that I realized he must have eaten them. My green thumb defeated by a dog with gourmet tastes.

    Next time I do that, I will place the pot higher up than a dog can reach 🙂

    1. Hi Frank, oh my gosh, this is the best comment ever!! Green onions and scallions are basically the same thing. The bulb versus the green. I am going to try growing my roots ends!! Linda

  3. Hi,
    This is the first time I have been to your wonderful “How to dehydrate green onions”.
    I saw that you dehydrator has either a plastic or metal screen on the trays. I have the Elite Platium Food Dehydrator and it has plastic trays with wider spaces in the trays. I was wondering if I can buy metal screen and put it ontop of the plastic trays for the smaller things like green onion. Do you think that would work?

    1. Hi Sheri, thank you for stopping by. I tried to find “parts” for your brand of a dehydrator. I think to be safe I would find the right kind of screens that will work with your unit. I would start by calling the company to see what is safe to use. Linda

  4. Oops! I read your warning of confetti in my dehydrator and tried to avoid that mess by cutting scallions into 3″ pieces first with plans to dice them when dry… oops. Two days of drying and they were still moist. Pulled them, diced them, and drying was a success! Dumped them from racks to a big sheet of paper to funnel them into jars.

    1. Hii Shawn, oh my gosh, the confetti, I love it! Oh well, now you know! Green onions are so easy to dehydrate, and having a few mason jars with them makes it nice when you need some green onions for a recipe! I’m so glad you tried doing them! Linda
