Step 1

Preheat oven to 350°F and set aside a 9x13-inch baking dish.

Step 2

Season chicken liberally with salt and pepper on both sides. Dredge chicken in flour, shaking off excess.

Step 3

In a large skillet over medium heat, heat the oil. Once hot, brown the chicken on both sides. (You don't need to cook it all the way through; it will finish cooking in the oven.) Transfer chicken to baking dish.

Step 4

Add butter to skillet and increase heat to medium-high. Add mushrooms and season with salt and pepper. Let cook until golden brown. Stir in sherry, and cook 1 to 2 minutes more. Stir in soup, mixing well, and cook until heated through.

Step 5

Pour sauce over chicken and top with cheese slices.

Step 6

Cover dish with foil and bake 30 minutes. Remove foil and turn oven to broil. Broil until cheese has browned, 1 to 2 minutes.

Step 7

Let sit 5 minutes before serving. Top with parsley and serve. Enjoy!
