Heat oven to 425 degrees.
Slide pan into oven and roast for 30 minutes or until lightly browned, basting every few minutes with the melted butter. Turn the oven down to 350 degrees and continue roasting for 30 minutes or until a thermometer in the chicken reads 160 degrees (This is Linda talking now instead of The Communal Chef. I don't know if it's an altitude difference but mine took more 45-50 minutes. Also, if your chicken is bigger than the 3 1/2 lbs the recipe calls for add 15 minutes per pound cooking time).
