Pat the chicken thighs dry with paper towels, season them generously with salt and pepper on both sides.
In a medium skillet over medium heat, melt the butter. Once melted, add the minced garlic and chopped rosemary. Sauté for about 1-2 minutes until fragrant, being careful not to burn the garlic.
In a large oven-safe skillet, heat the olive oil over medium-high heat. Add the chicken thighs, skin side down, and sear for about 5-6 minutes until golden brown. Flip the thighs and cook for an additional 3-4 minutes.
Pour the garlic rosemary butter mixture over the chicken thighs while the thighs are still in the skillet.
Place the skillet in the preheated oven and roast the chicken for 25-30 minutes or 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 before serving. Drizzle some remaining butter mixture from the skillet over the chicken.
Serve with fresh lemon wedges on the side and sprinkle with fresh parsley if desired.
