Pat the chicken thighs dry using paper towels and season both sides with salt and freshly ground black pepper.
In a medium skillet, melt the unsalted butter over medium heat. Add the minced garlic and chopped fresh rosemary, sauté for 1-2 minutes until fragrant.
In a large, oven-safe skillet, heat the olive oil over medium-high heat. Place the chicken thighs skin side down and sear for 5-6 minutes until golden brown. Flip and cook for an additional 3-4 minutes.
Pour the garlic and rosemary butter mixture over the thighs in the skillet, ensuring they are well coated.
Transfer the skillet to the preheated oven and roast for 25-30 minutes until the internal temperature reaches 165°F (74°C) and the skin is crispy.
Remove the skillet from the oven and let the chicken rest for about 5 minutes. Drizzle any remaining butter mixture over the chicken.
Serve with fresh lemon wedges and sprinkle with chopped fresh parsley if desired.
