Preheat the oven: Set oven to 400°F (200°C).
Prep the chicken: Pat the thighs dry with paper towels and trim any extra fat around the edges to prevent smoke in the oven.
Season: In a bowl, toss chicken with olive oil, paprika, salt, and pepper until evenly coated. Let rest for 10–15 minutes at room temperature.
Arrange and bake: Place chicken in a cast iron skillet. Scatter garlic cloves, lemon wedges, and herbs around them. Add butter if using.Bake uncovered for 25–30 minutes, flipping halfway through.
Optional broil: For golden color, broil the thighs for 1–2 minutes at the end. Keep an eye on them to avoid drying out.
Rest & serve: Let the chicken rest for 5 minutes, then spoon the pan juices over the top before serving.
