01 - Pat the chicken breasts dry with paper towels and 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 5–6 minutes per side until golden brown and cooked through to an internal temperature of 165°F. Transfer to a plate and tent loosely with foil to keep warm.
03 - In the same skillet, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to let it brown.
04 - Pour in the chicken broth and heavy cream, stirring well to combine and deglaze the skillet, scraping up any browned bits from the bottom.
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 and creamy.
06 - Stir in the chopped chives and parsley. Let the sauce simmer gently for 2–3 minutes, allowing it to thicken slightly.
07 - Place the chicken breasts back into the skillet, spooning the sauce over them. Simmer together for another 2–3 minutes until the chicken is heated through and fully coated.
08 - Transfer the chicken to serving plates and spoon the Boursin sauce generously over the top. Garnish with additional fresh chives if desired.
