01 - Pat chicken breasts dry with paper towels. Season both sides generously with salt and black pepper.
02 - Heat olive oil and butter in a large skillet over medium-high heat. Add chicken breasts and sear for 4 to 5 minutes per side until golden brown and nearly cooked through. Transfer chicken to a plate and set aside.
03 - Reduce heat to medium. Add minced garlic to the 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 creamy.
05 - Stir in fresh parsley and dried thyme. Allow the herbs to infuse into the sauce for about 1 minute.
06 - Return chicken breasts to the skillet along with any accumulated juices. Simmer for 7 to 10 minutes, turning chicken occasionally, until cooked through and sauce has thickened. Internal temperature should reach 165°F.
07 - Taste the sauce and add additional salt or pepper if needed.
08 - Transfer chicken and sauce to serving plates. Garnish with additional fresh parsley before serving hot.
