Yes, curd rice can be a good source of protein, particularly if it's made with Greek yogurt or curd that has a higher protein content. One cup (250 grams) of plain Greek yogurt contains approximately 23 grams of protein, while one cup of regular curd contains around 8 grams of protein. When rice is added to the curd, it further boosts the protein content of the dish. One cup of cooked rice contains around 3-4 grams of protein, depending on the variety.
