01 - Pat chicken breasts dry with paper towels, then 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 4–5 minutes per side until golden brown and nearly cooked through. Transfer 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. Allow herbs to infuse into the sauce for 1 minute.
06 - Return chicken breasts to the skillet, spooning sauce over the top. Simmer for 7–10 minutes, turning occasionally, until chicken reaches internal temperature of 165°F and sauce has thickened.
07 - Taste sauce and adjust seasoning with additional salt and pepper if needed. Garnish with extra fresh parsley and serve immediately.
