WHAT'S THE BEST WAY TO ROAST A TURKEY?

The Butterball Open Pan Roasting Method will consistently create a juicy, tender, golden brown, picture-perfect turkey.

Place thawed or fresh turkey, breast up on a flat rack in a shallow pan, 2 to 2-1/2 inches deep.
Brush or rub skin with oil to prevent the skin from drying and to enhance the golden color.
Insert oven-safe meat thermometer deep into the lower part of the thigh muscle, but not touching the bone. When thigh is up to temperature and if turkey is stuffed, move thermometer to center of stuffing for stuffing temperature. Make sure to follow the stuffing tips.
Place in a preheated 325°F oven.
When the turkey is about two-thirds done, loosely cover the breast and top of drumsticks with a piece of lightweight foil to prevent overcooking the breast.
Use this roasting schedule as a guideline; start checking for doneness 1/2 hour before recommended end times:
************************
Net Weight (in pounds) Unstuffed (in hours) Stuffed (in hours)
10 to 18 3 to 3-1/2 3-3/4 to 4-1/2
18 to 22 3-1/2 to 4 4-1/2 to 5 {HERE'S YOUR ANSWER.
22 to 24 4 to 4-1/2 5 to 5-1/2
24 to 30 4-1/2 to 5 5-1/2 to 6-1/4
***********************
Turkey is done when the meat thermometer reaches the following temperatures:

180°F deep in the thigh; also, juices should be clear, not reddish pink when thigh muscle is pierced deeply.
165°F in the center of the stuffing, if turkey is stuffed.
Before removing stuffing and carving, let turkey stand 15 minutes to allow juices to set.

Answer 4

That's a good one.. they usually call for about 20 minutes per pound.. so, I would go with at least 5 hours., in a pre heated oven at about 325..... baste it every half and hour, insert a meat thermometer if you have any question about it.. Cover it for the first hour.. good luck!

Answer 5

until the pop-up timer comes up. that should take every bit of 3 and a half to 4 hours...depending on the temperature.

Answer 6

30 min. per lb.
