Meanwhile, in a large saucepan, add remaining teaspoon of garlic powder and pepper to chicken broth.
Bring to a boil and add lemon juice and pasta. Cook over medium heat until all liquid is absorbed, stirring occasionally, approximately 25 minutes.
Cut up your chicken into bite-sized pieces and stir in to your pasta, along with the whipping cream and lemon zest.
Cook over low heat for 5 minutes, stirring every minute. Remove from heat. Let stand about 5 minutes before stirring and serving. (Sprinkle shredded or grated cheese on top if desired)
