Ingredients
  

  • 2 cups cooked chicken chopped or shredded
  • 16 ounces penne pasta
  • ½ cup unsalted butter
  • 2 cups heavy whipping cream
  • 4 ounces cream cheese
  • ½ teaspoon minced garlic
  • 1 teaspoon garlic powder
  • 1 teaspoon Italian seasoning
  • ¼ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 cup grated Parmesan cheese
  • 2 cups shredded mozzarella cheese
  • ¼ cup grated Parmesan cheese for topping

Instructions
 

  • Preheat your oven to 350°F (175°C).
  • Cook the penne pasta according to the package instructions until al dente. Drain, rinse, and set aside.
  • In a medium saucepan over medium heat, combine the butter, heavy cream, and cream cheese. Stir until smooth and fully melted.
  • Add the minced garlic, garlic powder, Italian seasoning, salt, and black pepper. Whisk until well combined.
  • Stir in the grated Parmesan cheese and simmer for 3–5 minutes until the sauce thickens slightly.
  • Place the cooked pasta into a large mixing bowl or back into the pasta pot. Pour the Alfredo sauce over the pasta and stir to coat evenly.
  • Fold in the cooked chicken until everything is well combined. This Baked Chicken Alfredo Pasta filling should be creamy and evenly coated.
  • Spread half of the pasta mixture into a greased 9×13-inch baking dish.
  • Sprinkle half of the mozzarella cheese over the pasta.
  • Add the remaining pasta mixture and finish with the remaining mozzarella and the extra Parmesan cheese.
  • Bake for 20–30 minutes until the cheese is melted, bubbly, and lightly golden.
  • Let the casserole rest for 5 minutes before serving.

Notes

  • Substitute penne with rotini, rigatoni, or ziti.
  • Use grilled chicken for extra flavor.
  • Mix in mushrooms or broccoli for added texture.
  • Serve with garlic bread, Caesar salad, or roasted vegetables.
