Preheat oven to 425, then bake chicken for about 25 minutes - this will vary depending which part, and how much chicken you're making. Legs, 25 mins; thighs, 30 mins; breasts, 35 mins. Estimated.
When your chicken timer (you set one, right?) goes off, turn pieces over. Kick the heat up to 450, and repeat bake time. (For example, another 25 mins for legs).
The potatoes need about 25 mins to be perfect, so add them at the appropriate time. I know some of you like to eat chicken skin. To crisp it up, turn the broiler on & give it a few mins.
WATCH THE CHICKEN CAREFULLY. The broiler will burn it in no time (I've heard). If your broiler is IN your oven (instead of a drawer underneath) take the potatoes out prior to broiling.
