Creating Creamy Mushroom Chicken is straightforward if you follow these steps:

1. Prepare Chicken: Season the chicken breasts with salt and pepper on both sides.
2. Heat Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Cook Chicken: Add the chicken breasts and sear for about 5-7 minutes on each side until golden and fully cooked. Remove from the skillet and set aside.
4. Sauté Aromatics: In the same skillet, add the chopped onion and cook until translucent, about 3-4 minutes. Add the minced garlic and sauté for an additional minute.
5. Add Mushrooms: Toss in the sliced mushrooms and cook until they are soft and browned, about 5 minutes.
6. Pour in Broth: Add the chicken broth to the skillet, scraping up any browned bits from the bottom.
7. Stir in Cream: Reduce the heat to low, then stir in the heavy cream and dried thyme. Let the sauce simmer for a few minutes until it thickens slightly.
8. Combine Chicken and Sauce: Return the cooked chicken to the skillet, coating it in the creamy sauce. Allow it to heat through for another 2-3 minutes.
9. Adjust Seasoning: Taste and adjust seasoning with more salt and pepper if needed.
10. Garnish and Serve: Remove from heat, garnish with fresh parsley, and serve warm.
