01 - Pat the chicken breasts dry with paper towels. Season both sides generously with salt and black pepper, ensuring even coverage.
02 - Heat olive oil and butter in a large skillet over medium-high heat until butter foams. Add chicken breasts and sear for 4–5 minutes per side until golden brown and nearly cooked through. Transfer to a plate and set aside.
03 - Reduce heat to medium. Add minced garlic to the same skillet and sauté for 30 seconds until fragrant, being careful not to burn.
04 - Add Boursin cheese, chicken broth, and heavy cream to the skillet. Stir continuously until the cheese melts completely and the sauce becomes smooth and velvety.
05 - Stir in fresh chopped parsley and dried thyme. Allow the sauce to simmer for 1 minute to meld flavors.
06 - Return chicken breasts to the skillet. Simmer for 7–10 minutes, turning occasionally, until chicken reaches an internal temperature of 165°F and the sauce thickens enough to coat the back of a spoon.
07 - Taste the sauce and adjust salt and pepper as needed. The sauce should be rich, creamy, and well-balanced.
08 - Transfer chicken to serving plates and spoon the sauce generously over each piece. Garnish with additional fresh parsley before serving immediately.
