I've been using this recipe for years and have found ways to refine it and make it even simpler without sacrificing taste. BTW, can also be made with shrimp rather than crawfish. Can easily be doubled or halved depending on the number being served.
This dish is always a hit at the family reunion and potluck dinners. It's creamy and cheesy and so easy to throw together. I don't remember where I got the recipe, but as often as my family requests it, I can make it with my eyes closed!
