Creating the delicious Creamy Mushroom Chicken is straightforward when you follow these simple steps:

1. Prepare the Chicken: Start by seasoning the chicken breasts with salt and pepper on both sides.
2. Heat the Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Sear the Chicken: Add the chicken breasts to the skillet and cook for 6-7 minutes on each side, or until golden brown and cooked through. Remove the chicken from the skillet and set aside.
4. Sauté the Mushrooms: In the same skillet, add the sliced mushrooms. Sauté until they are softened and browned, about 4-5 minutes.
5. Add Garlic: Stir in the minced garlic and cook for 1 minute until fragrant.
6. Make the Sauce: Pour in the chicken broth and bring it to a simmer. Stir in the heavy cream and let it thicken for about 3-4 minutes.
7. Incorporate Cheese and Thyme: Add the grated Parmesan cheese and dried thyme to the sauce. Stir until well combined and creamy.
8. Return Chicken: Place the seared chicken breasts back into the skillet, ensuring they are coated with the creamy sauce.
9. Simmer: Allow the chicken to simmer in the sauce for an additional 2-3 minutes to heat through.
10. Garnish and Serve: Sprinkle with fresh parsley before serving for an added touch.
