Rinse turkey; remove giblets, gizzard, and neck, and set aside.
Place turkey on a rack in broiler pan; sprinkle with salt and pepper. Add 1/2 cup water or stock to bottom of the pan along with turkey giblets, gizzard, neck, and any other trimmings. Place turkey in oven, legs-first.
Roast at 500° for 20-30 minutes or until top of turkey begins to brown; reduce heat to 350°. Continue to roast, checking after 1 hour or so; to keep top from overbrowning, cover with aluminum foil. If bottom of pan dries out, add water or stock, 1/2 cup at a time. Turkey is done when an instant-read thermometer inserted into thickest part of thigh measures 180°. If top is still not browned enough, remove foil and increase heat to 425° for last 20-30 minutes of cooking time.
Remove turkey from oven. Transfer to platter and make Simple Sherry Gravy while turkey rests (let sit for 20 minutes before carving).
