  • 2 tablespoons olive oil

  • 1 pound fresh shrimp, peeled and deveined

  • 1 pound bay or sea scallops, rinsed and drained

  • 3 tablespoons butter

  • 2 tablespoons all-purpose flour

  1. Preheat the oven to 400 degrees F (200 degrees C). Lightly butter 8 ramekins.

  2. Heat olive oil in a large skillet over medium-high heat. Add shrimp and scallops; sauté until opaque and firm, about 5 minutes. Remove from the heat.

  3. At the same time, melt butter in a medium saucepan over medium heat. Stir in flour until smooth, then gradually whisk in hot broth. Increase the heat to high and cook, stirring constantly, until thickened. Mix in wine, mushrooms, and shallots; cook for 5 to 10 more minutes.

  4. Arrange shrimp, scallops, and crabmeat in the bottom of the prepared ramekins. Pour sauce over seafood, then sprinkle with provolone and Parmesan cheeses.

  5. Bake in the preheated oven until golden, about 12 to 15 minutes.

  6. Remove from the oven, sprinkle with parsley, and serve.
