Instructions
Preheat the oven to 350 degrees F (175 degrees C). Spray a 9x13-inch baking dish with cooking spray.
Melt butter for cream sauce in a large skillet over medium-low heat. Add onion, celery, bell pepper, and garlic. Cook and stir until vegetables soften and onion turns translucent, 5 to 7 minutes.
Whisk flour and Creole seasoning into onion mixture to make a paste. Slowly add half-and-half, whisking constantly. Whisk in sherry, lemon juice, basil, and thyme. Season with salt and pepper. Cook, stirring constantly, until sauce thickens, 3 to 4 minutes. Remove from heat. Add mozzarella; stir until melted and combined.
Lightly season snapper and shrimp on both sides with seafood seasoning. Arrange snapper in a single layer in the prepared baking dish. Top with shrimp and mushrooms. Pour cream sauce over top. Sprinkle with Parmesan.
Bake, uncovered, in the preheated oven until fish flakes easily with a fork and shrimp are bright pink on the outside and the meat is opaque, about 30 minutes.
