Onion Butter Masala Dosa is a delectable South Indian dish that combines the crispiness of dosa with a flavorful onion masala filling and the richness of butter. Made from a fermented batter of rice and urad dal (black gram dal), this dosa is spread thinly on a hot griddle and cooked until golden-brown. Inside, it features a savory and aromatic filling of spiced onions cooked to caramelized perfection. The onions are sautéed with mustard seeds, curry leaves, turmeric, and other spices, creating a flavorful masala. This filling is complemented by a generous smear of butter that adds richness and enhances the overall taste experience. Onion Butter Masala Dosa is traditionally served with coconut chutney and sambar on the side. The coconut chutney provides a sweet and nutty contrast, while the sambar offers a tangy and spicy flavor. Together, they create a harmonious blend of tastes that perfectly complements the crispy dosa and savory onion masala filling. Onion Butter Masala Dosa is highly popular among dosa enthusiasts for its rich flavors and comforting appeal. The combination of crispy dosa, flavorful onion masala, and buttery richness makes it a favorite choice for breakfast, lunch, or dinner in South Indian cuisine.
