My southern cousin gave me this super-easy way to cook turkey 35 years ago. It isn't pretty to look at since the meat falls off the bones, but it is very moist and delicious which is what counts! My husband is the official carver of turkey so when I cook turkey this way, he's got a day off!
Preheat oven to 500 degrees (yes,500, it's not a misprint)
Clean turkey and salt and pepper it. Put a cup of water in the bottom of a large roaster pan. Turn turkey breast side down in pan. Fill cavity with water until full (about 3 cups). Put lid on the roaster pan and set timer for exactly 1 hour. Put it in the oven.
Shut off oven at 1 hour and leave door SHUT and go to bed.
Turkey will be done in the morning. Make dressing separately. Heat turkey before serving if desired.
