Oct 07, · Preheat oven to °F. Prepare a large enough roasting pan with a metal rack to accomodate both turkey portions in a single layer. Place the turkey on the rack. Pour olive oil over the turkey portions to coat/5(4). Add the turkey legs after the breast has been in the oven for 30 minutes, then after another 30 minutes add the thighs so they're done at about the same time. Be sure to leave enough room around each piece (about an inch) so the parts roast evenly. Put 1 and 1/2 cups of turkey or chicken broth in the bottom of the pan.
