Now that you have the ingredients, let’s go through the preparation process step-by-step:

1. Prepare the Chicken: Place each chicken breast between two pieces of plastic wrap. Use a meat mallet or rolling pin to pound the chicken to about ½ inch thickness.
2. Season the Chicken: Sprinkle the chicken breasts with salt and pepper on both sides.
3. Wrap with Prosciutto: Take two slices of prosciutto and lay them over each flattened chicken breast, covering as much area as possible. Place one sage leaf on top of each.
4. Dredge in Flour: Lightly dust the wrapped chicken breasts with flour, shaking off any excess.
5. Heat the Pan: In a large skillet, heat the olive oil and 2 tablespoons of butter over medium-high heat until hot but not smoking.
6. Cook the Chicken: Place the chicken breasts in the hot skillet, prosciutto side down. Cook for about 4-5 minutes until golden brown.
7. Flip and Continue Cooking: Carefully flip the chicken and add the remaining butter to the skillet. Cook for an additional 4-5 minutes until the chicken is cooked through and the prosciutto is crispy.
8. Add Liquids: Once the chicken is done, remove it from the pan and set aside on a plate. Pour the chicken broth and white wine (if using) into the skillet, scraping up the browned bits.
9. Reduce the Sauce: Bring the sauce to a simmer and let it reduce for about 2-3 minutes. This will concentrate the flavors.
10. Serve: Place the chicken back into the pan to coat with the sauce for a minute before serving.
