01 - Pat the chicken breasts dry with paper towels. Season both sides evenly with salt and black pepper.
02 - Heat olive oil in a large skillet over medium heat. Sear the chicken breasts for 5 to 6 minutes per side until golden brown and cooked through to an internal temperature of 165°F. Transfer to a plate and keep warm.
03 - In the same skillet, melt the butter over medium heat. Add the minced garlic and sauté for 1 minute until fragrant, stirring to prevent burning.
04 - Pour in the chicken broth and heavy cream, stirring well to combine and scrape up any browned bits from the bottom of the skillet to deglaze.
05 - Add the Boursin cheese to the skillet, breaking it apart with a spoon. Stir continuously until the cheese is fully melted and the sauce is smooth.
06 - Stir in the chopped chives and parsley. Let the sauce simmer gently for 2 to 3 minutes until it thickens slightly.
07 - Place the chicken breasts back into the skillet, spooning the sauce over them. Simmer for another 2 to 3 minutes until the chicken is heated through and well coated.
08 - Transfer the chicken to serving plates and spoon the Boursin sauce generously over the top. Garnish with additional fresh chives if desired.
