Onion powder is a finely ground spice made from dehydrated onions, offering a concentrated burst of onion flavor in a convenient, shelf-stable form. It is widely used in cooking to add depth and savoriness to dishes such as soups, stews, sauces, marinades, and spice blends without the need for chopping fresh onions. Onion powder blends seamlessly into both dry and liquid recipes, making it a staple in home kitchens and food industries alike. Rich in flavor and low in calories, it also retains some of the beneficial compounds found in fresh onions, including antioxidants. Its long shelf life and ease of use make onion powder an essential ingredient for quick and flavorful cooking.
