Preheat the oven to 400 F. Line two rimmed baking sheets with parchment paper or foil or spray with nonstick cooking spray.
Rub the chicken thighs with 1 to 2 tablespoons of the oil. Place them on the baking sheet and season with salt and pepper.
Bake the chicken for about 45 to 50 minutes, until the chicken is cooked through (an internal temperature of 165 F). Serve hot, room temperature, or cold.
