How to Make Onion Powder

Updated: Oct 25, 2023

Onion powder is such a great addition to your kitchen toolbox. Some of my (Marie’s) children are a little picky about onions in their food. By using the powder instead, I not only avoid tears at the dinner table but tears cutting up the onions as well. This really is such a simple process. For years I was buying it at the store until Emmaline showed me how easy this was to make and I have made my own ever since.
