DIY Onion Powder

Easy Homemade Onion Powder

Julia Child once said, “It’s hard to imagine a civilization without onions.”

And while they may seem insignificant, onions are one of the most important building blocks of any savory recipe, likely just as important as a dash of salt. Yellow onions in particular have the strongest flavor of any onion, which is why they’re a staple in nearly all of The Fresh 20 recipes.

And this one is no different. Because the one and only ingredient is… 1 yellow onion.

DIY Spices

Taking a little time to make your own spices can save money, add better flavor to recipes than store-bought, and help you avoid preservatives. There’s no match for fresh onion powder, so I’ve committed to making my own.

It’s a simple process that involves dehydrating the ingredients, then using a spice grinder to make a fine powder. The active prep time is really less than 5 minutes!

  2. Peel and thinly slice onion
