Onion is probably the most used vegetable in our house. We do a lot of cooking at home and onion is present in about 90% of those dishes, so we tend to keep it on hand. I’ve been going a bit crazy lately on ordering onions in our Imperfect Produce box, and I ended up with more than I know what to do with. Typically, I will chop them up and throw them in the freezer, but we have a ton in there already, so I decided to make onion powder instead.
I’ve been thinking a lot about preserving lately since summer is coming to an end. I was collecting herbs from the garden to dry and that triggered the thought of what to do with the onions. Making onion powder is a great way to preserve and store your onions without taking up too much space, and you don’t need a dehydrator to do it. Since I don’t have a dehydrator (yet), I just used my oven at its lowest setting, and it worked great. This is the same method I used to dry out oranges and apples for our winter garland.
Homemade Onion Powder
- To make the onion power, first, preheat your oven to its lowest temperature. Mine only goes down to 170 degrees.
- Next, peel and cut your onion(s) into thin slices. If you have a mandolin slicer it will make it much easier, but I just used a knife, and it turned out fine.
- Lay your onion slices out on a baking sheet. Bake in the oven for about 6 hours depending on the size of your slices.
- Once the onion slices are crisp and dry, you can throw them in a blender or spice grinder until they form a powder. Make sure to let the dust settle for a couple of minutes before open the lid.
- Store in a spice jar and enjoy.
