Cook pasta according to package directions. Drain and set aside.

Salt and pepper both sides of the chicken breasts. Heat half of the butter in a large skillet over medium-high heat. Add chicken breasts and cook until deep golden brown on both sides and done in the middle. Remove from the skillet, slice into thin strips, and set aside. Let the chicken rest to reabsorb liquids.

Add the remaining butter to the skillet, followed by the minced garlic. Stir the garlic around the pan to avoid burning, and cook for 1 minute. Pour in wine (or broth), then let it bubble up and reduce for 1 1/2 to 2 minutes. Add milk, cream, and extra salt and pepper as desired, whisking constantly until it's all combined. Allow liquid to heat up and thicken for a few minutes. If it gets too thick, you may thin it with a little chicken broth.

When the sauce looks good, remove it from the heat. Add Parmesan to the pan, then throw the hot pasta right on top of it. Toss it a bit. Add the chicken and continue tossing until it’s all combined. Again, if it gets too thick, splash in a little broth (you may return the pan to low heat if it needs it.)

Taste it, adjust seasonings, and top with minced parsley and extra Parmesan. Serve immediately!
