When I make a whole turkey, I use Convection Roast. The more exposed the turkey the better use a rack if you have one. I start by searing the backside up at 500 degrees for 15 min then, using wads of paper towel, I flip the turkey, again sear for about 15 min. then drop the temperature to 350. Insert the probe in the thickest part of the white meat avoiding bone, fat and gristle and roast to 160 degrees. It should reach temperature in about 2 -2 1/2 hours
