Preheat oven to 400F.
Mix onion, garlic, ginger, brown sugar, pepper, salt, soy sauce, olive oil, whiskey in a zip-top bag. Add chicken and marinate for 8-24 hours.
Place a cooling rack on a baking sheet and spray both with non-stick spray. Remove chicken from marinade and place on rack. Discard marinade.
Bake for 20 minutes, then turn chicken to cook evenly. Bake for 20-25 minutes longer, until chicken is cooked through.
