03When you are ready to cook, heat the oven to 375 degrees. Place on a foil-lined baking sheet. Roast, turning once halfway through, until an instant-read thermometer inserted in the center of the turkey reads 160 degrees, 45 minutes to 1 hour (it will continue to cook as it cools). Let stand 10 minutes before untying and slicing. Serve with remaining tapenade and mayonnaise on the side.
