Pound the chicken breasts down to about 1 inch thickness. Season both sides with salt and pepper.
Heat olive oil in a large skillet over medium heat, and cook the chicken until golden brown and cooked through (about 6-7 minutes per side). Remove to a plate, cover, and set aside.
In the skillet, add minced garlic and saute until fragrant. Deglaze the pan with the chicken broth, and simmer for 2 minutes before stirring in the heavy cream and water.
Stir in the Italian seasoning, onion powder, and salt and pepper.
Add the uncooked pasta to the sauce, and stir together. Cover with a lid and heat to a boil. Once it reaches a boil, reduce to a simmer and cook until pasta is tender - 10-14 minutes.
Once pasta is cooked, stir in the parmesan cheese until melted.
Slice the chicken and serve on top of the pasta.
Sprinkle with freshly chopped parsley and additional parmesan before serving.
