Preparation Steps

• Preheat oven to 375°F (190°C). Cook pasta shells according to package directions until al dente. Drain and set aside.
• In a large bowl, combine the cooked chicken, softened cream cheese, sour cream, shredded cheddar cheese, grated Parmesan cheese, Cajun seasoning, garlic powder, and onion powder. Mix well until thoroughly combined.
• Stuff each cooked pasta shell with the chicken mixture. Arrange the stuffed shells in a 9x13 inch baking dish.
• In a small bowl, whisk together the marinara sauce and heavy cream. Pour this mixture evenly over the stuffed shells.
• Cover the baking dish with foil and bake for 20 minutes. Remove the foil and bake for another 10-15 minutes, or until the sauce is bubbly and the cheese is melted and lightly golden.
• Garnish with chopped parsley before serving.
