Roasted garlic refers to a technique where whole cloves of garlic are roasted in an oven until they become soft and caramelized. This process brings out a rich, nutty flavor that is often used as a seasoning or garnish for various dishes such as pasta, bread, soups, stews, and salads. Roasted garlic can also be mashed or pureed to create a spread that can be used in cooking or as a condiment.
