Pat the chicken dry with paper towels and add to a cast iron skillet or roasting pan.
Combine the olive oil, salt, pepper, garlic powder, paprika and onion powder in a small bowl and mix well.
Using a spoon, lift the skin on the chicken breast to separate from the meat. Add a spoonful of the seasoning mixture under the skin.
Spread the remaining seasoning mixture evenly over the chicken, gently pressing the seasonings into the skin with your hands.
Place the skillet on the center rack and cook for approximately 70-90 minutes. Check internal temperature after an hour and to make sure the skin is not getting too dark.
Remove from heat and spoon the juices from the pan over the chicken.
Allow to sit for at least 15-20 minutes before slicing.
