Ingredients

For the Mushroom Filling:

  • 1 pound cremini mushrooms finely chopped
  • 2 cloves garlic minced
  • ¼ cup unsalted butter
  • ½ cup grated Parmesan cheese
  • ¼ cup fresh parsley finely chopped
  • Salt and freshly ground black pepper to taste

For the Chicken:

  • 4 boneless skinless chicken breasts
  • ¼ cup unsalted butter melted
  • ¼ cup grated Parmesan cheese
  • Salt and freshly ground black pepper to taste

Instructions
 

Prepare the Mushroom Filling:

  1. In a large skillet over medium heat, melt the butter. Add the minced garlic and sauté for approximately 30 seconds, or until fragrant. Add the chopped mushrooms and cook for 10 to 15 minutes, stirring occasionally, until they are softened and most of the moisture has evaporated. Stir in the grated Parmesan, chopped parsley, salt, and pepper. Remove from heat and allow to cool slightly.

Prepare the Chicken Breasts:

  1. If needed, pound the chicken breasts to an even thickness using a meat mallet. Carefully cut a deep horizontal slit along the side of each chicken breast to create a pocket, ensuring not to slice all the way through.

Stuff the Chicken:

  1. Spoon the cooled mushroom mixture evenly into each chicken breast pocket. Secure the openings with toothpicks to hold the filling in place during cooking.

Cook the Chicken:

  1. In a large skillet over medium-high heat, melt the remaining butter. Season the outside of the stuffed chicken breasts with salt and pepper. Place the chicken in the skillet and cook for approximately 5 to 7 minutes per side, or until golden brown and fully cooked through. During the final minute of cooking, sprinkle the tops with additional Parmesan cheese.

Rest and Serve:

  1. Remove the chicken from the heat and allow it to rest for 5 to 10 minutes before removing toothpicks and serving. Serve warm with preferred side dishes such as mashed potatoes, steamed vegetables, or rice.
