In a skillet over medium heat, melt 2 tablespoons of butter and sauté 2 minced garlic cloves until fragrant, about 1 minute. Add 1 cup of lobster and 1 cup of crab meat, cooking for 2-3 minutes until heated through. Remove from heat, allowing the seafood to cool while you prepare the filling.

In a mixing bowl, combine the sautéed seafood mixture with 8 ounces of softened cream cheese, 1 cup of shredded mozzarella cheese, and a pinch of salt and pepper. Use a spatula to blend the ingredients until smooth and creamy. Set aside, giving the flavors a moment to meld while you cook the pasta.

Bring a large pot of salted water to a boil. Carefully add the jumbo pasta shells and cook according to the package instructions until al dente, typically around 10-12 minutes. Once cooked, drain the shells and let them cool slightly, as you'll be stuffing them soon.

In the same skillet used for the seafood, melt another 2 tablespoons of butter over medium heat. Whisk in 2 tablespoons of flour to create a roux, cooking for 1 minute. Gradually stir in 1 cup of heavy cream and ½ cup of grated Parmesan cheese, whisking until the sauce is creamy and smooth, about 3-4 minutes.

Preheat your oven to 375°F (190°C). Spread a thin layer of the creamy sauce in the bottom of a baking dish. Take the cooled pasta shells and generously stuff them with the seafood filling, placing them in the dish. Cover the shells with the remaining sauce, ensuring they’re well coated.

Cover the baking dish with aluminum foil and bake for 20 minutes. Afterward, remove the foil and bake for an additional 10 minutes until the top is bubbly and golden brown. The aroma of the Creamy Seafood Stuffed Shells will fill your kitchen, signaling that dinner is almost ready.

Once finished baking, let the dish cool for a few minutes to set. Garnish with extra Parmesan cheese or fresh herbs, if desired. Serve the Creamy Seafood Stuffed Shells warm and watch everyone enjoy this luxurious comfort food delight!
