Place Alfredo sauce, chicken broth, and pasta in a 12-inch skillet.
Bring to a simmer over medium heat, stirring occasionally to prevent pasta from sticking to the bottom of the pan. Continue simmering until pasta is cooked through, about 15 to 20 minutes.
For extra creamy pasta, stir in cream cheese until melted and combined.
Top with chicken, grated parmesan cheese, and chopped parsley.
Season with salt and pepper to taste.
Serve immediately.
Notes
Al dente is the ideal consistency for pasta. The pasta will be tender and will still have a slightly firm texture when you bite into it.
If you would like to thin out the sauce a bit, add hot water to the pan and stir until the sauce is smooth.
