Creating Creamy Garlic Mushroom Chicken Thighs is simple if you follow these steps:

1. Prepare the Chicken: Season the chicken thighs with salt and pepper on both sides.
2. Brown the Chicken: Heat olive oil in a large skillet over medium-high heat. Add the chicken thighs, skin-side down, and cook for about 5-7 minutes or until they are golden brown. Flip and brown the other side for an additional 5 minutes. Remove and set aside.
3. Sauté the Mushrooms: In the same skillet, add butter. Once melted, add the sliced mushrooms. Sauté for about 5 minutes or until they are soft and browned.
4. Add Garlic: Stir in the minced garlic and cook for another minute until fragrant.
5. Make the Sauce: Pour in the chicken broth and scrape up any browned bits. Add the heavy cream and thyme. Stir to combine.
6. Return Chicken to Skillet: Place the browned chicken thighs back in the skillet. Spoon some sauce over the top.
7. Simmer: Reduce the heat to low, cover, and let it simmer for 20 minutes until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
8. Garnish and Serve: Once done, sprinkle with fresh parsley before serving.

Following these steps will ensure your dish is rich, savory, and oh-so-delicious.
