Good marsala wine is obviously a key ingredient in Chicken Marsala, but what else is needed to make a successful version of this sweet and savory Sicilian classic? Not much else except some patience and attentiveness. Mushrooms are a necessity, but I left out the onions, shallots, chicken stock, tomatoes, flour, capers, lemon, and whatever else all the internet recipes tell you to put into the dish. I wanted to create an easy, no mess version of Chicken Marsala that captured the fundamental essence of the dish and here it is.
