This depends on the turkeys' size. If you have a turkey that is over 14 pounds you will want to roast it at 325F degrees and if it's under 14 pounds, you'll want to roast it at 350F degrees. Roasting at a higher temperature can make the turkey meat become dry, so having a kitchen thermometer is necessary because the turkey will be done when the center reaches about 165F degrees. Measure the thickest part of the meat without touching the bone.
