Making Creamy Seafood Stuffed Shells is an enjoyable task. Follow these simple steps to create a delicious meal:

1. Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a 9×13 baking dish.
2. Cook the Pasta: Bring a large pot of salted water to a boil. Add the jumbo pasta shells and cook them al dente according to package instructions. Drain and set aside.
3. Prepare the Filling: In a mixing bowl, combine ricotta cheese, chopped shrimp, chopped scallops, crab meat, half of the mozzarella cheese, garlic powder, onion powder, and fresh parsley. Season with salt and pepper to taste. Mix well until all ingredients are evenly combined.
4. Stuff the Shells: Carefully fill each cooked pasta shell with the seafood mixture. Place stuffed shells in the prepared baking dish, opening side up.
5. Make the Sauce: In a separate bowl, mix heavy cream and marinara sauce. Pour the sauce evenly over the stuffed shells, ensuring they are well covered.
6. Add Cheese: Sprinkle the remaining mozzarella cheese over the top of the shells, along with grated Parmesan cheese for added flavor.
7. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for about 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.
8. Garnish: Once baked, remove from the oven and let it rest for a few minutes. Garnish with additional fresh parsley before serving.

These steps lead to a wonderful dish that captures the essence of indulgent comfort food.
