Step 1: Prepare and Sear the ChickenSeason the chicken breasts generously with salt and pepper on both sides. Heat olive oil in a large skillet over medium-high heat until shimmering. Place the chicken breasts in the hot pan and sear for 4-5 minutes on each side until golden brown. The key here is not to overcrowd the pan – work in batches if necessary. A good sear forms a flavor-packed crust that seals in moisture, preventing the common mistake of dry chicken. Transfer the seared chicken to a plate and set aside.Pro Tip: For even cooking, pound chicken breasts to an even thickness of about 3/4 inch before cooking.Step 2: Create the Boursin SauceReduce the heat to medium and add minced garlic to the same pan, sautéing for 30 seconds until fragrant but not browned. Pour in the chicken broth, scraping the bottom of the pan with a wooden spoon to release those flavorful browned bits (culinary term: fond). Bring the liquid to a simmer and add both packages of Boursin cheese, stirring continuously until the cheese begins to melt. Pour in the heavy cream and add thyme and rosemary, continuing to stir until the sauce is smooth and slightly thickened (about 3-4 minutes).Chef's Insight: The sauce should coat the back of a spoon but still flow freely. If it's too thick, add a splash of broth; if too thin, simmer for an additional 2-3 minutes.Step 3: Combine and Finish the DishReturn the chicken breasts to the pan, nestling them into the creamy Boursin sauce. Reduce heat to low, cover, and simmer for 8-10 minutes, or until the chicken reaches an internal temperature of 165°F (74°C). Occasionally spoon the sauce over the chicken to ensure it absorbs the rich flavors. Once fully cooked, remove from heat and let the dish rest for 5 minutes before serving. This resting period allows the juices to redistribute throughout the meat, resulting in more tender chicken. Garnish with fresh chopped parsley before serving.Finishing Touch: For an extra flavor boost, grate a small amount
