Today it’s all about how to dehydrate green onions or scallions. Plus, how to make green onion powder. Can you tell I love to dehydrate food? It takes up less space on my pantry shelves.

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.

Step Three

The green onion (white section) part is on the left. It takes longer to dehydrate because the white part of the onion is thicker. The scallions are the longer green part of the green onions.

These took about 2-3 hours to dehydrate. The white sections took a lot longer to dehydrate.

Step Four

You can see the scallions on the top and the thicker white part of the green onions in the bottom of the dehydrator pictured below.

Step Five

The thicker white onion sections are on the left and the green scallions are on the right. They begin to blow all over the dehydrator when they are dry. I want you to know that up front.

They are perfect to dehydrate, and then you use your FoodSaver to seal the pints or quart jars.

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

    I do all this but instead of throwing away the root parts I plant and get a whole new crop. Thanks for all your good ideas.

    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!!!

    The most popular phrase at our home is Gramma can I throw this away or do you need it for something first.

    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 🙂

      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
