Onion Powder

Onion powder is a fine, pale-beige seasoning made from dehydrated onions ground to a uniform powder. It delivers concentrated onion flavor that disperses evenly and dissolves quickly, making it ideal for dry rubs, sauces, and dressings. A warm, sweet aroma blooms on contact with heat; common retail forms include true powder and the coarser granulated onion.

Commercial onion dehydration expanded in the early 20th century, and production now spans the United States, India, and China. It anchors many American and European pantry blends and is produced by slicing, drying, and milling primarily white or yellow onions.
