Crab Meat au Gratin is the best hot crab dip EVER! You will love this authentic Louisiana recipe. It's an easy, seafood party appetizer!
You can make this ahead of time and put it in the refrigerator until you're ready to serve. Cover it with aluminum foil and bake it at 350°F for about 20-25 minutes before topping it with the extra cheese and popping it under the broiler.
