# Directions:
01 - In a large skillet over medium heat, melt ½ tablespoon butter. Add garlic; sauté 1 minute until fragrant. Stir in lobster and crab meat, cook for 2–3 minutes until just heated through. Remove from heat and set aside.
02 - In a large bowl, combine the cooked seafood, softened cream cheese, ½ cup mozzarella, salt, and pepper. Mix until fully combined and creamy.
03 - Boil jumbo shells in salted water according to package instructions until al dente. Drain and set aside to cool slightly.
04 - In the same skillet, melt remaining 1 tablespoon butter over medium heat. Stir in flour; cook 1 minute. Slowly whisk in ½ cup heavy cream. Add grated Parmesan and remaining ½ cup mozzarella, stirring until smooth and creamy. Season with salt and pepper to taste.
05 - Preheat oven to 375°F. Spread a thin layer of cheese sauce on the bottom of a 9x13-inch baking dish. Stuff each shell generously with seafood filling; arrange in the baking dish. Pour remaining cheese sauce evenly over the shells.
06 - Cover with aluminum foil; bake 20 minutes. Remove foil and bake 10 minutes more, or until sauce is bubbly and top is golden.
07 - Let cool slightly. Garnish with extra Parmesan or fresh herbs. Serve warm.
