Preheat oven to 350 degrees Fahrenheit.
Rinse the chicken under cold running water and dry with paper towels.
Sprinkle salt and pepper into the cavity, then rub all over the skin.
Place chicken in a roasting pan lightly coated with cooking spray or olive oil.
Cook for 1 hour without taking off the cover (the time may vary depending on your oven - cooking times may be shorter when using a convection oven).
After cooking for 1 hour, check the internal temperature of the drumstick with the meat thermometer.
If it reads 165 degrees Fahrenheit, take it out of the oven; if not, continue to cook.
When done, remove chicken from pan and let sit 5 minutes before cutting into pieces (or allow to cool completely then cut into pieces).
