Preheat your oven to 425°F (220°C).
Pat the chicken thighs dry with paper towels.
Place the chicken in a large bowl and drizzle with olive oil.
Sprinkle garlic powder, onion powder, smoked paprika, salt, and pepper.
Toss to coat the chicken evenly.
Arrange the chicken thighs skin-side up on a baking sheet.
Roast in the oven for 35-40 minutes until the skin is golden brown.
Use a meat thermometer to ensure the internal temperature reaches 165°F (75°C).
Let the chicken rest for 5 minutes before serving.
