A vegetable casserole is a baked dish that typically combines a variety of vegetables, such as carrots, broccoli, and bell peppers, with a binding agent like cheese, cream, or sauce. It is often topped with breadcrumbs or additional cheese for added texture and flavor. This dish can be served as a main course or a side dish, making it versatile for different meals. Casseroles are popular for their ease of preparation and the ability to use leftover or seasonal vegetables. They can be customized with different ingredients, such as herbs, spices, or even grains like rice or quinoa, to suit individual tastes and dietary preferences.
