Remove any giblets from the inside of your chicken and pat the outside of the chicken dry with paper towels.
Rub the entire surface of the chicken with olive oil and then sprinkle generously with kosher salt & pepper. Make sure you get the seasoning on all parts of the chicken, especially the thighs & wings!
Place the chicken breast-up on a rack in a roasting pan (this will get you the crispiest skin since the air can circulate around the whole chicken) or in a large baking dish.
Roast in the oven for about 1 hour and 15 minutes, until the internal temperature between the thigh and breast reaches 165 degrees Fahrenheit and the skin is golden and crisp. If the chicken it not done after 75 minutes, continue checking at 10 minute intervals.
Remove the chicken from the oven and let rest for 10 minutes to let the juices redistribute throughout the meat before slicing and serving.
