Cover baking sheet with aluminum foil for easier clean-up. Place oven-safe rack over foil. Spray with non-stick cooking spray.
Place chicken thighs on baking rack and rub each with olive oil on both sides.
In a small bowl, stir together seasonings. Rub onto both sides of chicken thighs.
Place in oven and set for 400 degrees. Bake for 35 minutes, turning halfway for even color.
Thighs should no longer pink at the bone and the juices should run clear. An instant-read thermometer inserted near the bone should read 165 degrees Fahrenheit.
Notes
By placing the chicken thighs in a cool oven, the fat renders as the oven heats up but the skin will crisp when the oven reaches the designated temperature. Also, the baking rack helps the air to circulate around the chicken to promote even doneness.
