Sprinkle seasoning over top of the chicken, and gently pat (but do not rub, or it will come off the skin).
Flip chicken over and sprinkle more seasoning and rub into crevices.
Cook chicken at 380F for 25-30 minutes, skin side down first, flipping at 15 minutes in. Chicken is done when it reaches an internal temperature of 165F** Repeat with remaining chicken.

Notes
*chicken thighs are pretty fatty on their own. Feel free to skip the extra oil. I feel it helps distribute seasoning and crisp thighs perfectly, but you can skip the extra oil if you want to avoid it! **bone-in chicken can reach 165F but still be pink near the bones (dark meat). I like to cook mine a little extra to prevent or reduce this. I cooked my second batch for 30-35 minutes, so they were much darker on the outside than in the photos, but no complaints from the family.
