Preheat your oven to 400°F (200°C).
In a large oven-safe skillet, heat the olive oil over medium-high heat. Season the chicken thighs with salt, black pepper, garlic powder, thyme, and rosemary.
Once the oil is hot, add the chicken thighs skin-side down to the skillet. Sear for about 5-7 minutes until the skin is golden brown. Flip the chicken and cook for an additional 3-4 minutes.
Remove the chicken from the skillet and set aside. In the same skillet, pour in the white wine, scraping the bottom to deglaze the pan. Let it simmer for 2-3 minutes.
Stir in the heavy cream and Dijon mustard, mixing well until combined. Return the chicken thighs to the skillet, skin-side up.
Transfer the skillet to the preheated oven and roast for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Once cooked, remove the skillet from the oven and let it rest for 5 minutes. Garnish with fresh parsley before serving.
