Onion Flakes are a convenient, long-lasting form of dehydrated onions that have been chopped into small pieces. They provide a concentrated, savory flavor and aroma, similar to fresh onions but with none of the preparation. A popular kitchen staple, onion flakes are used in a wide range of dishes, from soups and stews to spice rubs and savory baked goods. They rehydrate when cooked, making them a versatile and easy-to-use ingredient.
