Preheat the oven to 425°F (220°C). Line a rimmed baking sheet with foil and set aside.
Pat the chicken thighs dry with paper towels, removing as much moisture as possible.
Place the thighs skin-side up on the prepared baking sheet. Drizzle the olive oil over the thighs and rub it into the skin to coat evenly.
In a small bowl, combine Italian seasoning, salt, black pepper, garlic powder, onion powder, and paprika.
Sprinkle the seasoning mixture evenly over all sides of the chicken and rub it into the skin.
Bake for 35 to 40 minutes, or until the skin is crisp and an instant-read thermometer inserted into the thickest part reads 165°F (74°C).
Let the chicken rest for a few minutes before serving.
