Roasted vegetables refers to a cooking technique where vegetables are placed in an oven or on a stove top and cooked until they become tender, caramelized, and flavorful. The high heat causes the natural sugars in the vegetables to caramelize, resulting in a rich, savory taste that is popular among food enthusiasts. Roasted vegetables can be eaten as a side dish or incorporated into main courses such as pasta or stir fry dishes for added flavor and nutrition.
