Description

A simple, creamy oven-baked pasta dish featuring tender chicken, penne, and a cheesy Alfredo sauce topping.


Ingredients

Scale
  • 3 skinless, boneless chicken breast halves
  • 1 (8 ounce) package penne pasta
  • 1/2 (16 ounce) jar Alfredo sauce
  • 1 1/2 cups shredded mozzarella cheese, divided
  • 1/4 cup milk
  • 1 tablespoon onion powder
  • 1 tablespoon garlic powder
  • 1 cup shredded Cheddar cheese

Instructions

  1. Preheat your oven to 350 degrees F (175 degrees C).
  2. Place chicken in a pot, cover with water, and bring to a boil over high heat. Reduce heat and simmer for about 15 minutes, until the chicken is no longer pink inside and the juices run clear.
  3. At the same time, bring a large pot of lightly salted water to a boil. Add the penne and cook until tender yet firm to the bite, about 11 minutes. Drain the pasta.
  4. Drain the cooked chicken and cut it into bite-size pieces.
  5. In a large bowl, combine the chicken, cooked noodles, Alfredo sauce, 1/2 cup of the mozzarella cheese, milk, onion powder, and garlic powder. Mix everything well.
  6. Pour the mixture into a 1 1/2-quart casserole dish.
  7. Layer the remaining mozzarella cheese and the Cheddar cheese on top.
  8. Bake in the preheated oven for about 25 minutes, until the cheese is melted and bubbly.

Notes

  • For a lighter dish, use a reduced-fat Alfredo sauce.
  • You can substitute rotisserie chicken for the fresh cooked chicken to save time.
  • Add steamed broccoli florets to the mixture for extra vegetables.
