The turkey I use for holidays!
Leaving the roasting bag or foil over the breast for the entire duration traps steam and prevents the skin from turning golden brown and crisp. Proper heat management from 400 degrees Fahrenheit down to 350 degrees Fahrenheit prevents the exterior from burning while cooking the interior safely.
Positioning the oven rack in the lowest third of the oven ensures the large bird receives adequate top clearance and browns evenly under radiant heat. Tying the legs together maintains a compact shape that cooks at a consistent rate. Sliding seasoned butter beneath the breast skin protects the leanest meat from drying out during extended exposure to dry heat.
