Sear the Chicken – Season both sides of the chicken with salt, pepper, and Italian seasoning. Heat butter or olive oil in a large skillet over medium heat. Sear the chicken for 5 minutes per side until beautifully golden. Remove and set aside.
Create the Flavor Base – In the same pan, add minced garlic and chopped onion. Stir for 2 minutes until fragrant and softened.
Build the Creamy Sauce – Pour in the chicken broth and scrape up any browned bits from the pan. Let it simmer for a minute before adding the Boursin cheese. Stir until fully melted.
Perfect the Texture – Lower the heat and pour in the heavy cream. Whisk gently until the sauce thickens into a velvety consistency.
Bring It Together – Return the chicken to the pan, spooning the sauce over each piece. Let it simmer for 3–5 minutes until the chicken reaches an internal temperature of 165°F.
Serve & Garnish – Sprinkle with fresh parsley and serve immediately over mashed potatoes, rice, or roasted vegetables.
