01 - Pat the chicken breasts dry with paper towels and season both sides generously with salt and pepper.
02 - Heat olive oil and butter in a large skillet over medium-high heat. Add chicken breasts and sear for 4-5 minutes per side until golden brown and nearly cooked through. Remove chicken and set aside on a plate.
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 the 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 if using, allowing the herbs to infuse into the sauce.
06 - Return chicken breasts to the skillet. Simmer for 7-10 minutes, turning occasionally, until the chicken is fully cooked through and the sauce has thickened slightly.
07 - Taste the sauce and adjust salt and pepper if needed. Garnish with additional fresh parsley before serving.
