Portobello mushrooms are a mature form of the button mushroom (Agaricus bisporus), known for their large size, dark brown cap, and meaty texture. In India, they are less common and usually available in premium supermarkets or grown in controlled climate farms due to specific temperature requirements. Portobello mushrooms are rich in nutrients and are widely used in grilling, burgers, sandwiches, and continental dishes because they work well as a vegetarian meat substitute.
