6 servings


  • 3 skinless, boneless chicken breast halves

  • 1 (8 ounce) package penne pasta

  • ½ (16 ounce) jar Alfredo sauce

  • 1 ½ cups shredded mozzarella cheese, divided

  • ¼ cup milk

  • 1 tablespoon onion powder

  • 1 tablespoon garlic powder

  • 1 cup shredded Cheddar cheese


  1. Preheat the oven to 350 degrees F (175 degrees C).

  2. Place chicken into a pot and cover with water. Bring to a boil over high heat; reduce heat and simmer until no longer pink in the centers and juices run clear, about 15 minutes.

  3. At the same time, bring a large pot of lightly salted water to a boil. Add penne and cook, stirring occasionally, until tender yet firm to the bite, about 11 minutes. Drain.

  4. Drain cooked chicken and cut into bite-size pieces.

Cook's Notes:

You can use any medium pasta noodles that you prefer, such as ziti, large elbow, etc.

If using the second half of a jar of Alfredo sauce, swirl the milk in the jar to get all of it out.
