Butterfly the chicken breasts and season on both sides with some salt and pepper to taste.
Heat the oil in a large, high-sided frying pan on a medium-high setting. Fry the chicken for about 4-5 minutes on each side, until browned and completely cooked through. Remove from the pan and set aside on a plate.
Boil the pasta in salted water as per the package instructions.
Add the butter to the pan you cooked the chicken in and reduce to a medium-low setting. Allow the butter to melt, then add the garlic and fry for 2 minutes, stirring constantly.
Add the cream and Italian herbs and stir well. Let it bubble for a couple of minutes.
Add the Parmesan cheese and some salt and pepper to taste, stir and let everything cook for another few minutes.
Add ¼ cup of the pasta water to the sauce and stir it in. Then drain the pasta and add that too, stirring to combine it with the sauce.
Slice up the chicken breasts and serve on top of the pasta. Add some fresh chopped parsley to garnish if desired.
