Creating Creamy Mushroom Chicken can be straightforward with these easy-to-follow steps:

1. Prepare the Chicken: Season the chicken breasts with salt and pepper.
2. Heat the Pan: In a large skillet, heat olive oil over medium-high heat.
3. Cook the Chicken: Add the chicken breasts to the skillet. Cook for about 5-7 minutes on each side until golden brown and cooked through. Remove the chicken from the skillet and set aside.
4. Sauté the Onions and Garlic: In the same skillet, add butter, diced onion, and minced garlic. Sauté for 2-3 minutes until the onions are translucent and fragrant.
5. Add Mushrooms: Stir in the sliced mushrooms and cook for an additional 5 minutes until they are tender and have released their moisture.
6. Mix in Cream and Chicken Broth: Pour in the heavy cream and chicken broth, stirring until well combined. Add dried thyme, and season with more salt and pepper if desired.
7. Simmer: Let the sauce simmer for about 5 minutes, allowing it to thicken slightly.
8. Combine with Chicken: Return the cooked chicken breasts to the skillet, ensuring they are coated with the creamy sauce. Cook for an additional 2-3 minutes to heat through.
9. Garnish: Remove from heat, sprinkle with fresh parsley, and serve immediately.
