Move your oven rack to the lowest position. Preheat the oven to 425℉
Clean and pat dry the turkey. If you brined your turkey, make sure to rinse it well to avoid overly salty gravy.
Place the turkey in the roasting pan. Fold wing tips up and underneath the bird to avoid overcooking. If you have a neck, place it in the bottom of the roasting pan.
Stuff the turkey cavity with the onion, garlic, butter, rosemary and thyme.
In a small bowl, mix together softened butter, olive oil, garlic powder, onion powder, rosemary, and thyme.
Slide your hand underneath the turkey skin and gently move the turkey skin away from the breast meat. Take half of the rub and place it underneath the turkey skin over both turkey breasts. The remaining half, rub over the entire top of the turkey.
Place turkey in the oven and roast at 425℉ for 30 minutes.
Tent the turkey with aluminum foil and reduce the oven temperature to 325℉ for the remainder of the cooking time (13-15 min per pound), until a 165℉ internal temperature is reached.
Remove turkey from the oven and allow it to rest for 20-30 minutes to allow the meat to rest before serving. Enjoy!
