How to Make Onion Powder and Onion Flakes

It's time to re-stock my onion powder and onion flakes.  Here is how you can make your own using a dehydrator (you could also use your oven if the temperature goes low enough).





Simply peel your onions, and chop them up.   You can use a non-electric hand chopper or simply dice them up quickly in a food processor. You can also dry them in slices if that's what you need for future meals, but they are too large to fit into a coffee grinder to make into powder.







Spread the chopped onions on parchment paper lined dehydrator trays, and dry in your dehydrator according to the instructions it comes with.

When the onions are dried, simply break apart your diced onions for "flaked" onions.  Place the remainder in a small coffee grinder and grind until it becomes a powder.

Store the onion flakes in airtight glass jars in your spice cabinet.  These will also collect moisture, so you may want to store them using my next tip.



Store the onion powder in your freezer to keep it dry and prevent it from hardening.  If you place it in your cabinet it will quickly harden, unlike garlic powder.  You can also put some white rice, a few beans in it, but I typically don't shake mine out.  I measure with a measuring spoon, and it's much easier for me if I don't have anything in the onion powder.  Shallot powder also hardens over time.

I recycled a jar the size of a half pint to store my onion powder, using a screw top lid.  My canning funnel fits in it perfectly to pour it out of the grinder easily.

Thanks for this tip. I bought a 3 pound bag of white onions yesterday and was hoping they wouldn't go bad before I could use them. I'll be using your tips from this post to make onion slices, diced onion and onion powder.
granny j, the slices would be great for soups this winter. I plan on getting more. We did not plant any this season.

That is good to know about the onion powder. I was just thinking that I should try to make some - I use it fairly often and would rather use my own onions. I hadn't realized it would harden and would not have been happy to be faced with a block of 'powder'!
I've preserved lots of food over the years but never made my own onion powder. What a goof! I sure will now. Thanks!
Susan, I have tried to come up with a way to keep the onion powder dry, and this is working so far.
Donna, I use onion powder as much as garlic, and love it! So much fresher than store bought too.

Question

  I have asked this before, but I know I follow a few writers who have written (and published) novels.  What is the best free or best least expensive (simple like Word) writing software to use that is not Google Docs? Thanks! I'll be back with an update soon I hope.  But I do appreciate your help, because I cannot find the information some of you suggested.

Horsetail Salve ~ A "first" this Year

We purchased some horsetail salve to try last year.  It is said to help with severely dry, cracked skin.  My husband was the first to try it, with very, very dry and cracked hands from work. He loves it!  He joked I could not have it back.   I started the infused, horsetail oil the last part of March. Something I learned:   horsetail is also called shavegrass. I infused horsetail in oil, and strained it.  I then made horsetail salve.  I remembered to label my jar with what oil(s) I used, so I can journal this all in my "Herbal Remedies" journal.  I often forget to write the oil used. Now, the one we bought, has more in it than I put in ours, as far as ingredients (the purchased salve had lanolin, and aloe).  We'll see if ours works just as good.  I added the sage essential oil, and vitamin E oil. A "first" time experience for us this year.    I bought the larger tins at a seed store in an Amish area last year.  They a...

  The pickings are slim right now, but we'll take anything we are blessed with.  I made a salad and cleaned the beans.  The rain will give us more for a meal in a day or so.  The green beans are every so slowly coming on this season. I made a batch of homemade granola, and instead of my homemade vanilla extract, I used my homemade Christmas Spice Extract.  It smelled so good in the oven, and while cooling.   I picked some purslane, and am doing an experiment with it this time.  Update soon.   Chit Chat ©  August 2026 by Kristina at Pioneer Woman at Heart
