This flavorful rice dish originated in southern Louisiana during the 1700's and 1800's. According to Wikipedia, it was first made by enslaved Africans using rice and "undesirable" cuts of meat like organ meat. Over time, this traditional meal has adapted to the changing food supply and is now usually made with higher quality meat like ground beef and Andouille sausage. Health conscious versions like my vegetarian dirty rice are also becoming more common.
