Now my favorite way to serve Chicken Marsala is not over the traditional pasta but over mashed potatoes. I had it that way at an Italian restaurant one time and have been hooked on potatoes as my side of choice for this dish ever since. The marsala sauce is wonderful over potatoes. *sigh* Pure Italian comfort food!
All-purpose flour, for dredging
Kosher salt and freshly ground black pepper
1/4 cup extra-virgin olive oil
4 ounces prosciutto, thinly sliced
8 ounces crimini or porcini mushrooms, stemmed and halved
1/2 cup sweet Marsala wine
1/2 cup chicken stock
2 tablespoon unsalted butter
1/4 cup chopped flat-leaf parsley
Put the chicken breasts side by side on a cutting board and lay a piece of plastic wrap over them; pound with a flat meat mallet, until they are about 1/4-inch thick. Put some flour in a shallow platter and season with a fair amount of salt and pepper; mix with a fork to distribute evenly.
Lower the heat to medium and add the prosciutto to the drippings in the pan, saute for 1 minute to render out some of the fat. Now, add the mushrooms and saute until they are nicely browned and their moisture has evaporated, about 5 minutes; season with salt and pepper. Pour the Marsala in the pan and boil down for a few seconds to cook out the alcohol. Add the chicken stock and simmer for a minute to reduce the sauce slightly. Stir in the butter and return the chicken to the pan; simmer gently for 1 minute to heat the chicken through. Season with salt and pepper and garnish with chopped parsley before serving.
