Marinate the turkey the day before cooking.
In a bowl, mix together olive oil, garlic, onion, rosemary, thyme, parsley, lemon zest & lemon juice.
Place turkey on roasting rack in a large roasting pan. Rub the entire outside of turkey with marinade. (You can also rub the marinade under the turkey skin) Cover the turkey with plastic wrap and refrigerate overnight.
Remove turkey from the refrigerator 1 hour before cooking. Preheat oven to 325 degrees.
Melt butter and pour over the turkey. Season turkey with the pepper. Place the turkey in oven and cook until 160-165 degrees at the thickest part of the thigh using a thermometer.
Remove turkey from the oven, tent with foil and let rest 30 minutes before slicing.
We do not recommend stuffing the Heritage Turkey as that will increase the cooking time and the danger of drying out the turkey. Cook the stuffing on the side in a separate pan. The Heritage Turkey will be done before the Stuffing will be fully cooked.
