Preheat the cast-iron skillet while you prepare the chicken. Place the skillet in a 500 degree Fahrenheit oven and let the skillet heat!
Rub the entire chicken, front and back, legs, thighs… every inch with olive oil, salt, and pepper.
Remove the hot skillet from the oven to place the whole chicken in it.
Place the skillet and chicken back in the oven and cook for 15 minutes. The chicken will become a very nice dark, golden brown.
Lower the oven temperature to 350 degrees and cook the chicken for another 30-40 minutes until the chicken is a nice, golden, crispy brown color.
Use a meat thermometer to test the temperature, read more below.
The chicken is cooked when the thermometer reads 165 degrees Fahrenheit. You can remove at 160 and it will continue to cook to 165.
Remove and let it sit for a minute. Spoon the juice on the bottom of the pan over the chicken.
