Onion powder is a fine-textured spice made from dehydrated onions. It has a pale yellow to beige color and a concentrated flavor reminiscent of fresh onions. It is commonly used as a seasoning and flavoring agent in various dishes, providing a convenient way to incorporate onion flavor without the need for chopping or sautéing onions. Onion powder is versatile and can be used in soups, stews, sauces, marinades, dressings, and spice blends. It adds depth and complexity to recipes and is particularly popular in dishes where a milder, more evenly distributed onion flavor is desired.
