It takes a long time. One day in the fridge for each 5 lbs. A 20 lb. turkey will take 4 days in the refrigerator. If you need to defrost in a hurry you will need to take drastic action and provide a running bath of cold water, not a static bath. Check often and prepare for the oven as soon as possible.
The key here is temperature is not your friend with food. Bacteria will grow between 40 and 160 degrees (they actually never stop growing, even in the freezer but grow much, much slower) The amount of time a turkey (or other food) spends in this danger zone is crucial. So get that turkey into a hot oven as soon as it is defrosted in this manner.
An 11 pound turkey should be cooked for about 3 hours. The turkey can roast in the oven at 325 degrees.
A 13 lb turkey should be roasted for about 3 to 3.5 hours at 325F until it reaches an internal temperature of 165F.
To roast a 14.8 lb stuffed turkey thoroughly and deliciously, cook it at 325F for about 4 to 4.5 hours. Use a meat thermometer to ensure the internal temperature reaches 165F in the thickest part of the turkey.
A 20 lb brined turkey should be cooked for about 4 to 5 hours at 325F until it reaches an internal temperature of 165F.
A 20 lb stuffed turkey should be cooked for approximately 4.5 to 5 hours at 325F until it reaches an internal temperature of 165F.
20 minutes per lb - plus 20 minutes. Therefore, you would cook this weight for 90 minutes in total.
1/2 per pound at 350 degrees
Really not a good idea to roast a turkey at that high a heat. It will become dried out and burned on the outside. Roast it at 325 f - 25 minutes per pound.
read the instructions on the packaging... usually about 4 hours for a large turkey.
