Ingredients

  • 12 ounces penne pasta
  • 2 cups cooked chicken shredded or diced
  • 2 cups Alfredo sauce
  • 1 cup heavy cream
  • 2 cups shredded mozzarella cheese divided
  • ½ cup grated Parmesan cheese divided
  • 1 teaspoon garlic powder
  • 1 teaspoon Italian seasoning
  • ½ teaspoon onion powder
  • Salt and black pepper to taste
  • 2 tablespoons chopped fresh parsley optional
  • Optional Add-Ins
  • 2 cups steamed broccoli
  • 1 cup fresh spinach
  • ½ cup cooked bacon bits
  • ½ cup sliced mushrooms
  • Crushed red pepper flakes

Instructions

  • Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish. Cook the penne pasta until just al dente according to the package directions. Drain well.
  • In a large mixing bowl, whisk together the Alfredo sauce, heavy cream, garlic powder, Italian seasoning, onion powder, salt, and black pepper until smooth.
  • Add the cooked pasta, shredded chicken, 1 cup mozzarella cheese, and ¼ cup Parmesan cheese to the sauce mixture. Stir until everything is evenly coated.
  • Transfer the mixture to the prepared baking dish. Sprinkle the remaining mozzarella and Parmesan evenly over the top.
  • Cover with aluminum foil and bake for 20 minutes. Remove the foil and continue baking for 10–15 minutes, or until the cheese is melted, bubbly, and lightly golden.
  • Let the casserole rest for 5 minutes before serving. Garnish with chopped parsley and serve warm.

Notes

  • Rotisserie chicken makes this recipe even quicker.
  • Cook pasta just until al dente, so it doesn't become soft while baking.
  • Freshly shredded cheese melts much more smoothly than pre-shredded cheese.
  • Add broccoli or spinach for extra vegetables.
  • For a crispier cheese topping, broil for 2–3 minutes after baking.
