01 - Pat chicken breasts dry with paper towels. Season both sides generously with salt and pepper.
02 - Heat olive oil and butter in a large skillet over medium-high heat. Add chicken and sear 4 to 5 minutes per side until golden brown and nearly cooked through. Remove from skillet and set aside.
03 - Reduce heat to medium. Add minced garlic to the same skillet and sauté 30 seconds until fragrant.
04 - Add Boursin cheese, chicken broth, and heavy cream to the skillet. Stir continuously until cheese melts completely and sauce becomes smooth and creamy.
05 - Stir in fresh parsley and dried thyme until well combined.
06 - Return chicken breasts to the skillet. Simmer 7 to 10 minutes, turning occasionally, until chicken is cooked through and sauce has thickened nicely.
07 - Taste the sauce and adjust salt or pepper as needed.
08 - Sprinkle additional fresh parsley over the top just before serving.
