Slow Roasted Turkey Recipe

This method appeals to me even though slow roasting is not recommended due to health risk
question...after browning 20 mins@500F....do you turn the oven dial to 200F while not opening the door, or do you open the door , wait till it goes down to 200F and then continue???
Thanks Bob

Bob,
The best slow roast recipe I have found, and I have cooked 100's of turkeys since being a chef, is to (brine the bird is desired) cook a 25 lb bird at 200d for 12-13 hrs upsidedown 2/3 the time. last 1/3 flip the bird rightside up and 30 mins before finishing broil to crisp the skin. Super simple, sounds worse then it is. Use a thermometer to temp the bird, 165d internal. Hope it helps.

Bob, after browning 20 minutes @ 500F, you turn down the oven dial to 200F and YOU KEEP THE DOOR CLOSED! The oven will slowly lose heat while cooking the bird, raising the internal temp to a safe level before all the juices have a chance to cook out.
