- 4 skinless, boneless chicken breast halves
- sea salt and ground black pepper to taste
- 1 tablespoon extra-virgin olive oil, or more as needed
- 2 tablespoons unsalted butter, divided
- 6 (1 ounce) slices prosciutto, cut into thirds
- 1 small shallot, minced
- 8 ounces crimini mushrooms, stemmed and halved
- 1/2 cup sweet Marsala wine
- 1/2 cup chicken stock
- 1/4 cup chopped flat-leaf parsley
- Place chicken cutlets between 2 sheets of plastic wrap on a solid, level surface. Firmly pound the meat with the smooth side of a meat mallet to a 1/4-inch thickness. Season both sides with salt and pepper.
- Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high heat until butter is melted. Place chicken cutlets into the skillet; cook until both sides are golden brown, about 5 minutes for each side.
- Lower the heat to medium; add olive oil to the skillet if needed. Place prosciutto and shallots into the skillet; cook and stir until warmed, about 1 minute. Stir in the mushrooms and cook until browned, about 5 minutes. Season with salt and pepper. Pour wine into skillet; simmer until flavors combine, about 1 minute. Add chicken stock; simmer and stir until the sauce reduces slightly, about 1 minute.
- Stir 1 tablespoon of butter into the skillet. Return chicken to the pan; simmer until chicken is heated through, about 1 minute. Garnish with parsley, salt, and pepper.
