Ingredients

  • 2 boneless, skinless chicken breasts (about 1 pound total), butterflied (see Notes)
  • Kosher salt and freshly ground black pepper
  • 2 tablespoons grated Parmesan
  • 3 tablespoons flour
  • 3 tablespoons unsalted butter, divided
  • 2 tablespoons extra virgin olive oil
  • 1 cup sliced cremini mushrooms
  • 3/4 cup (about 1 large) sliced leek, white parts only
  • 2 teaspoons minced fresh garlic
  • 3 tablespoons freshly squeezed lemon juice
  • 1/3 cup chicken stock (preferably homemade)
  • 3 tablespoons dry white wine
  • 2 tablespoons capers, drained
  • 3 tablespoons chopped fresh parsley

Method

  • Place the chicken breasts between two sheets of plastic wrap and pound with a meat mallet (or a small cast-iron pan) until they are 1/4 inch thick.
  • Season the chicken very lightly with salt and pepper (not too much, since the capers in the sauce add salt).
  • On a plate, combine the Parmesan and flour; dredge the chicken pieces in the cheese mixture and shake off the excess.
  • In a large skillet over medium-high heat, melt 2 tablespoons of the butter; add the olive oil.
  • Cook the chicken breasts for 3 minutes per side, or until juices run clear when the tip of a knife is inserted into the center.
  • Remove the chicken from the pan and keep warm.
  • Add the mushrooms and leeks to the skillet and saute for 2 to 3 minutes, or until softened.
  • Add the garlic, lemon juice, chicken stock, wine, capers, and parsley.
  • Reduce the liquid in the pan by about two thirds, until the sauce is thickened and syrupy.
  • Add the remaining butter to the sauce, and stir until combined.
  • Spoon the sauce over the chicken and serve.
