At 350 F. How long to cook 13 pound turkey?

At 350°F, a 13-pound turkey typically takes about 3 to 3.5 hours to cook. It's important to ensure the internal temperature reaches at least 165°F in the thickest part of the breast and innermost part of the thigh. Using a meat thermometer can help ensure it's fully cooked. Let the turkey rest for about 20-30 minutes before carving for the best results.
