½cupdry Marsala wine not cooking wine; or more chicken stock
1tablespoonsherry vinegaror red wine vinegar
½cupchicken broth
2teaspoonschopped fresh thyme or 2 tablespoons chopped fresh parsley
Instructions
Split each chicken breast in half horizontally to create two thinner pieces of chicken (called cutlets). (Carefully place your hand on top to get a feel for whether or not you are slicing the chicken evenly.) Lay a piece of plastic wrap on top of the chicken, then with the flat side of a meat mallet or a rolling pin, gently pound it into an even thickness (about 1/4-inch or so thick). Season both sides of the chicken using 1/2 teaspoon salt and the pepper. In a shallow dish (a pie dish works well), place the flour. With tongs, lightly dredge the chicken on both sides.
In a large, high-sided skillet, heat 1 tablespoon of the oil over medium-high. Once the oil is hot and shimmering, add 2 of the chicken pieces in a single layer (angle the chicken away from you as you set it down). Cook the on both sides until golden brown and the chicken is cooked through, about 2 to 3 minutes per side. Transfer to a plate and tent with foil to keep warm. Add the remaining 1 tablespoon oil, then repeat with the remaining 2 chicken pieces.
To the skillet, add 2 tablespoons butter, shallot, garlic, mushrooms, and remaining 1/2 teaspoon salt. Cook until the mushrooms soften and begin to brown, about 6 to 8 minutes.
Pour in the Marsala and vinegar. Stir, scraping along the bottom of the pan. Let cook until the Marsala is reduced by half, about 3 minutes.
Add the chicken broth and let simmer 1 minute. Stir in the remaining 1 tablespoon butter. Carefully taste and add more salt or pepper as desired, then add the chicken back to the skillet. Let heat through briefly (30 seconds to 1 minute). Sprinkle all over with fresh thyme. Enjoy immediately.
