Preheat the oven to 425 degrees Fahrenheit. For easier cleanup, line a baking sheet with parchment paper. In a small bowl, mix the paprika, onion powder, garlic powder, chili powder, oregano, salt, and pepper.
Drizzle the olive oil over the chicken thighs and then sprinkle the thighs with the spices. If you're not planning on eating the skin, sprinkle the spices under the skin. (See notes)
Place the chicken thighs on the baking sheet and bake for 35-40 minutes, or until the internal temperature reaches 165 degrees Fahrenheit.
