01 - Pat the chicken breasts thoroughly dry with paper towels. Season both sides evenly with kosher salt and freshly ground black pepper.
02 - Heat the olive oil in a large skillet over medium heat. Once the oil shimmers, place the chicken breasts in the pan and sear for 5 to 6 minutes per side until deeply 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 unsalted butter over medium heat. Add the minced garlic and sauté for approximately 1 minute, stirring constantly, until fragrant and lightly golden.
04 - Pour in the chicken broth to deglaze the pan, scraping up any browned bits from the bottom. Add the heavy cream and stir to combine thoroughly.
05 - Add the Boursin cheese to the skillet, breaking it apart with a wooden spoon. Stir continuously until the cheese has fully melted and the sauce is smooth and velvety.
06 - Stir in the chopped chives and parsley. Let the sauce simmer gently for 2 to 3 minutes, stirring occasionally, until it thickens enough to coat the back of a spoon.
07 - Nestle the seared chicken breasts back into the skillet, spooning the sauce over the top. Simmer together for another 2 to 3 minutes until the chicken is heated through and fully coated.
08 - Transfer each chicken breast to a warm plate and spoon the Boursin sauce generously over the top. Garnish with additional fresh chives and serve immediately.
