Preheat the oven to 450°F (230°C).
Place a cast-iron pan or oven-safe skillet on the stovetop over medium heat to warm while you prepare the chicken.
In a large bowl toss the 6 skin-on chicken thighs with 1 teaspoon olive oil until each piece is lightly coated.
In a small bowl combine 1/4 teaspoon salt, 1/4 teaspoon pepper, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, and 1/2 teaspoon smoked paprika; mix well.
Sprinkle the seasoning mixture over the oiled chicken and toss or rub to coat each thigh evenly.
Carefully add the chicken thighs to the preheated skillet, skin-side down, and cook 4–5 minutes until the skin is browned and releases from the pan.
Flip the thighs and cook an additional 4–5 minutes on the other side.
Transfer the hot skillet to the preheated oven and roast 15–20 minutes, or until the chicken reaches your desired doneness (internal temperature about 165°F / 74°C).
Remove the skillet from the oven and let the chicken rest a few minutes before serving.
