01 - Pat the 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 constantly until the cheese melts completely and the sauce becomes smooth and velvety.
05 - Stir in fresh chopped parsley and dried thyme. Allow the herbs to infuse into the sauce for about 30 seconds.
06 - Return chicken breasts to the skillet, spooning sauce over the top. Simmer for 7 to 10 minutes, turning occasionally, until chicken is fully cooked through and sauce has thickened to coat the back of a spoon.
07 - Taste the sauce and adjust salt and pepper as needed.
08 - Transfer chicken and sauce to serving plates. Garnish with additional fresh parsley and serve immediately.
