Onion Uthappam is a savory South Indian dish that features a thick, pancake-like dosa topped with finely chopped onions and sometimes other vegetables. The batter for uthappam is similar to that used for dosas, made from fermented rice and urad dal (split black gram). The batter is poured onto a hot griddle and spread into a thick, round shape. Chopped onions are sprinkled generously on top, along with optional ingredients like tomatoes, green chilies, or cilantro. The uthappam is cooked until it is golden brown and crispy on the bottom while remaining soft and spongy on the top. It is typically served with coconut chutney, sambar, and sometimes with a spicy tomato chutney, making it a flavorful and hearty option for breakfast or a light meal.
