Preheat the oven to 350°F.
Remove the giblets from the turkey and rinse the turkey inside and out. Trim any excess fat and leftover pinfeathers, then pat the outside dry with paper towels. Place the turkey in a large roasting pan.
1 12-pound fresh turkey
Combine all the dry seasonings in a small bowl.
2 Tablespoons sea salt, 1 teaspoon black pepper, 2 teaspoons dried thyme, 1 Tablespoon dried oregano, 1 teaspoon smoked paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, 3 dried bay leaves
Brush the outside of the turkey with the melted butter, then sprinkle and rub the seasoning mix evenly over the entire turkey and in the cavity. Stuff the cavity with the fresh herbs, onion, and garlic. Tie the legs together with kitchen string and tuck the wing tips under the turkey to prevent burning.
1 small bunch fresh Italian parsley, 1 small bunch fresh thyme, 1 yellow onion, 4 tablespoons unsalted butter, 1 head garlic
Roast the turkey for about 2 1/2 hours, basting occasionally with pan juices. The turkey is done when the juices run clear when you cut between the leg and thigh, and an instant-read thermometer reads 165°F (74°C) in the thickest part of the thigh.
Transfer the turkey to a cutting board, cover with foil, and let it rest for 20 minutes before carving. Slice and serve hot.
