Combine the thyme, parsley, onion powder, garlic powder, Cajun seasoning, smoked paprika, salt and pepper in a small bowl.
Coat the chicken with the olive oil, rub on all of the spice mixture, then set aside to marinate – the longer the better! Overnight is best!
Place the marinated chicken in a baking dish, cover with foil, and place in a 400 degree oven for ½ hour.
Meanwhile, whisk together the bone broth and the flour.
Remove the chicken from the oven, and pour the broth/flour mixture all around the chicken, then cover and place back into the over for another ½ hour.
Remove the chicken from the oven, baste with the pan juices, then return the chicken to the oven, uncovered, basting every 15 minutes until roasted.
Once cooked, cover and let rest for 10 minutes, then enjoy!
