Onion powder is a concentrated savory seasoning made from whole onions that have been peeled, sliced, and fully dehydrated before being ground into a fine, flour-like dust. It captures the essence of fresh onions without the moisture or texture, making it an essential pantry staple for “tear-free” cooking.
