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 chopped parsley and dried thyme. Let the herbs infuse into the sauce for about 1 minute.
06 - Return chicken breasts to the skillet. Simmer for 7 to 10 minutes, turning occasionally, until chicken is fully cooked through and sauce has thickened to desired consistency.
07 - Taste sauce and adjust seasoning with additional salt and pepper if needed. Garnish with extra fresh parsley before serving.
