Thin the chicken first: If your chicken breasts are especially large, slice them in half horizontally or pound them to an even thickness. They will cook more evenly and soak up more of that buttery cream sauce.
Add a little color: For a fresher look and flavor, scatter a bit of chopped parsley over the top before serving. It is not necessary, but it does make the plate look mighty nice if company is coming.
Watch the heat: Keep the cream at a gentle simmer
