Creating the perfect oven roasted turkey is straightforward if you follow these steps:

1. Preheat the Oven: Preheat your oven to 325°F (165°C).
2. Prepare the Turkey: Remove the turkey from its packaging, and remove the giblets and neck from the cavity.
3. Rinse and Dry: Rinse the turkey under cold water and pat it dry with paper towels.
4. Season the Turkey: In a bowl, mix the softened butter, olive oil, salt, pepper, garlic powder, onion powder, thyme, rosemary, and sage. Rub this mixture all over the turkey, including under the skin and inside the cavity.
5. Stuff the Turkey: If using stuffing, loosely fill the cavity of the turkey with your stuffing mixture. Do not overpack, as the stuffing expands during cooking.
6. Add Broth: Pour the chicken broth into the roasting pan, surrounding the turkey.
7. Truss the Legs: Use kitchen twine to tie the turkey legs together for even cooking.
8. Roast the Turkey: Place the turkey breast-side up on a rack in a roasting pan. Roast in the preheated oven for approximately 3 to 4 hours. Baste every 30 minutes for added moisture.
9. Check the Temperature: Use a meat thermometer to ensure the internal temperature reaches 165°F (74°C) in the thickest part of the breast and thigh.
10. Rest the Turkey: Once cooked, remove the turkey from the oven and let it rest for 30 minutes. This allows juices to redistribute for a moist turkey.
11. Carve and Serve: Carve the turkey and serve it with your favorite sides and gravy.

By following these steps carefully, you will achieve an incredible oven roasted turkey that will impress everyone at your table.
