Preheat your oven to 375°F (190°C). Grease a shallow, ovenproof baking dish and set aside.
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Stir in the flour and cook for 2 minutes, stirring constantly, to form a roux.
Gradually whisk in the milk, white wine, and heavy cream, allowing the mixture to thicken into a smooth sauce. Stir in the nutmeg, salt, and pepper. Remove the sauce from heat and set aside.
In a large skillet, melt the remaining 2 tablespoons of butter over medium heat. Add the shallots and sauté until softened, about 2 minutes.
Add the scallops, shrimp, and mussels to the skillet. Cook for 3-4 minutes, or until the seafood just begins to turn opaque. Remove from heat and stir in the chopped parsley.
Transfer the cooked seafood and shallot mixture to the prepared baking dish. Pour the béchamel sauce evenly over the top.
In a small bowl, combine the breadcrumbs, Parmesan cheese, and olive oil. Sprinkle this mixture evenly over the gratin.
Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and the sauce is bubbly.
Remove from the oven and let rest for 5 minutes before serving. Serve with lemon wedges on the side for a fresh citrus twist.
