Authentic dirty rice usually contains gizzards & livers, or some other form of giblets, but don't fret if you don't like them. You can simply increase the beef or pork and still have a wonderful meal. Take it easy on the Cajun seasoning though - add a little, taste and adjust!
This recipe was wonderful with one note. It is intended to be made and consumed immediately. In other words, don't try to make it in advance and reheat or hold it. Instead, cook it just before you intend to serve it, and then serve it hot and direct from the oven.
Crawfish, simmered in a very simple butter roux, seasoned with a basic trinity, garlic, stock and Cajun seasoning, and finished with a little fresh parsley and green onion. Serve over hot rice with fresh French bread for dipping.
