This deliciously-melty macaroni and cheese features fresh shrimp and lump crab meat baked into it. We load this casserole with six different kinds of cheese for a cheese-lovers delight. Perfect for the holidays, this dish serves 8 to 12 people and since the recipe calls for tapioca starch & arrowroot starch instead of flour, it can be modified to be completely gluten free if you use gluten free noodles!
