Preheat the oven to 400°F and line a baking sheet with parchment paper or lightly grease a baking dish.
Prepare the chicken. Pat the chicken quarters dry with paper towels and place them in the prepared baking dish. Drizzle lightly with olive oil.
Make the seasoning blend. In a small bowl mix together parsley, smoked paprika, garlic powder, thyme, rosemary, salt, and black pepper.
Season the chicken. Sprinkle the seasoning mixture generously over both sides of the chicken, making sure to gently lift the skin and season under the skin as well for extra flavor.
Bake the chicken. Place the chicken in the oven and bake for 50–60 minutes, or until the chicken is cooked through and the skin is golden and crispy.
Prepare the garlic herb butter sauce. While the chicken is baking, add butter to a small saucepan over medium heat. Stir in minced garlic, thyme, rosemary, parsley, salt, and pepper. Cook for 1–2 minutes until fragrant and the butter is fully melted.
Finish the dish. Remove the chicken from the oven and pour the butter sauce over the chicken.
Pour the garlic herb butter sauce over the hot chicken quarters so it soaks into the crispy skin.
Serve and enjoy! The chicken will be juicy, flavorful, and coated in a rich garlic herb butter sauce that makes this dish absolutely delicious.
