Directions

Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish or similar casserole dish with butter or cooking spray.
Sauté the vegetables: In a large skillet over medium heat, melt the butter. Add the diced onion, bell pepper, and celery, and sauté for 5-7 minutes until softened. Add the garlic and cook for an additional 30 seconds.
Make the creamy sauce: Sprinkle flour over the vegetables and stir for 1-2 minutes. Gradually whisk in the milk or half-and-half, stirring until the mixture thickens (about 3-5 minutes). Add the cream cheese and stir until smooth.
Add seafood and seasonings: Remove the skillet from heat and gently fold in the shrimp, crabmeat, shredded cheeses, mayonnaise, lemon juice, Worcestershire sauce, Old Bay seasoning, paprika, salt, pepper, and parsley. Stir until evenly mixed.
Assemble the casserole: Pour the seafood mixture into the prepared baking dish, spreading evenly.
Prepare the topping: In a small bowl, combine panko breadcrumbs, Parmesan cheese, and melted butter. Sprinkle this mixture evenly over the casserole.
Bake: Place the casserole in the oven and bake for 25-30 minutes, or until bubbly and golden brown on top.
Serve and enjoy: Let the casserole cool for a few minutes before serving. Garnish with more parsley if desired.
