Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C).

Place chicken in a lightly greased baking dish. Squeeze lemon over both sides of the chicken breasts and season both sides using 1 1/2 teaspoons garlic powder and 3/4 teaspoon pepper.

Bake in the preheated oven until juices run clear and chicken is no longer pink inside, about 40 minutes.

Meanwhile, in a large saucepan, season the chicken broth with the remaining 1/2 teaspoon garlic powder and 1/4 teaspoon pepper.

Bring to a boil and add lemon juice and pasta. Cook over medium heat, stirring occasionally, until all liquid is absorbed, about 25 minutes.

Cut cooked chicken into bite-sized pieces and stir into cooked pasta, along with the cream and lemon zest. Cook, stirring, over low heat for 5 minutes.
