Onion Uttapam is a traditional South Indian dish made using a thick layer of dosa batter spread on a hot tawa. It is topped with a mix of finely chopped onions, green chilies, coriander, and optional vegetables like tomatoes or carrots. The uttapam is cooked on both sides until golden and crispy. This wholesome dish is served hot with coconut chutney or sambar for a hearty breakfast or snack.
