Description

Chicken Alfredo Casserole is a one-dish, dump-and-bake comfort meal featuring rotisserie chicken, penne pasta, and a creamy Alfredo sauce topped with mozzarella and cheddar.


Ingredients

Scale
  • 3 cups rotisserie chicken, shredded
  • 12 oz uncooked penne pasta
  • 3 cups Alfredo sauce
  • 2 cups chicken broth
  • 1 cup milk
  • 1 1/2 cups shredded mozzarella cheese
  • 1 cup shredded cheddar cheese
  • 2 cloves garlic, minced
  • 1 tsp Italian seasoning
  • 1/2 tsp black pepper
  • 1/2 tsp paprika
  • Fresh parsley, for garnish

Instructions

  1. Preheat oven: Set to 375°F (190°C). Grease a 9×13-inch baking dish.
  2. Mix ingredients: In the baking dish, combine uncooked penne, shredded chicken, Alfredo sauce, chicken broth, milk, garlic, Italian seasoning, pepper, and paprika. Stir until everything is evenly incorporated.
  3. Cover & bake: Cover tightly with foil and bake for 40–45 minutes, or until the pasta is tender.
  4. Add cheese: Remove foil, sprinkle mozzarella and cheddar evenly over the top.
  5. Final bake: Return to the oven uncovered for 10–15 minutes, or until the cheese is melted and bubbly.
  6. Serve: Let cool for a few minutes, then top with fresh parsley. Enjoy warm!

Notes

  • No need to boil pasta—just mix and bake for a creamy, hands-off dinner.
  • Use leftover rotisserie chicken to cut prep time even more.
  • For a lighter version, swap in part-skim milk and reduced-fat cheese.
  • Leftovers keep well in the fridge for up to 3 days; reheat in the microwave or oven.
  • Prep Time: 10 minutes
  • Cook Time: 40-45 minutes (covered) + 10-15 minutes (uncovered)
