Step 1

In a large shallow bowl mix salt and pepper into flour. Dip chicken cutlets into flour and shake off excess. Set coated cutlets on a parchment or wax paper-lined baking sheet.

Step 2

In a large pan saute the prosciutto over medium heat for 5 minutes in 2 tablespoons of olive oil. Add the mushrooms and continue to cook until they release their water (about 5 minutes). Set mushrooms and prosciutto aside in a bowl tented with foil.

Step 3

In the same pan add a bit more olive oil and 1 tablespoon of butter. Cook the chicken in batches (about 3 minutes per side) until browned. Work in batches adding more oil and butter if required. Set all chicken aside in a plate and tent with foil.

Step 4

To the pan add the Marsala wine and chicken stock. Scrape the bottom of the pan with a wooden spoon to dislodge the flavor bits. Turn heat to medium-high and cook for 3-5 minutes until the sauce is slightly reduced.

Step 5

Turn heat to low and add the remaining butter. Swirl it around or whisk to form the sauce. If the sauce is not thick enough add a slurry of 1 tablespoon of cornstarch mixed with 1 ounce of water. Turn heat to high and stir until thickened (about 1 minute). When satisfied with the sauce's consistency, taste test and make final adjustments to salt and pepper levels.

Step 6

Finally, add the chicken, mushrooms, and prosciutto back to the pan and heat through for 1-2 minutes until hot. Top with parsley and serve. Enjoy!
