Prepare the Chicken: Season the chicken breasts with salt and pepper on both sides.

Sauté the Chicken: In a large skillet, heat olive oil over medium-high heat. Add the chicken breasts and cook for about 6-7 minutes per side, or until golden brown and cooked through. Remove from the skillet and set aside.

Cook the Mushrooms: In the same skillet, add sliced mushrooms and sauté until they are browned and tender, about 5 minutes. Add minced garlic and cook for an additional minute until fragrant.

Create the Sauce: Pour in the chicken broth and bring to a simmer. Stir in the heavy cream and thyme. Allow the sauce to cook for a few minutes until it thickens slightly.

Combine: Return the cooked chicken to the skillet, spooning the sauce over the top. Heat through for a couple of minutes.

Serve: Garnish with chopped parsley and serve over pasta, rice, or mashed potatoes.
