Prepare the Chicken: Season the chicken breasts with salt, pepper, and dried thyme on both sides.
Sear the Chicken: In a large skillet, heat the olive oil over medium-high heat. Add the chicken breasts and sear for 5-6 minutes on each side until golden brown and cooked through. Remove the chicken from the skillet and set aside.
Sauté the Mushrooms: In the same skillet, melt the butter. Add the sliced mushrooms and sauté for about 5 minutes, or until they are browned and tender. Add minced garlic and cook for an additional minute until fragrant.
Create the Sauce: Reduce the heat to medium-low, then pour in the heavy cream and stir to combine. Gradually add the grated Parmesan cheese, stirring until melted and smooth.
Combine Chicken and Sauce: Return the chicken to the skillet, spooning the mushroom sauce over the top. Simmer for an additional 2-3 minutes, allowing the flavors to meld together.
Serve: Garnish with freshly chopped parsley before serving.
