This Chicken Diane recipe is all about building layers of flavor as you cook. Searing chicken and then browning mushrooms in a skillet creates delicious browned bits on the bottom of the pan. When the liquids are added, those browned bits release their flavor, resulting in a rich, silky, savory sauce. Fresh lemon juice and parsley are mixed in at the end for brightness. Serve the finished dish with egg noodles and a salad.
