Make sure your turkey is defrosted. Preheat the oven to 325°F.
In a medium bowl, add the butter, dried rosemary, dried thyme, dried sage, sea salt, and pepper. Stir to combine completely. Set aside.
Add the roughly chopped onions and chicken broth to a roasting pan.
Remove the turkey packaging, neck, and the bag of giblets from the turkey, pat dry with paper towel. Add the turkey breast side up to the roasting pan.
Starting at the neck and working your way down, slide fingers underneath the skin and rub half the butter between the bird and skin. With the remaining half of the butter, rub it on the outside of the skin.
Add the fresh rosemary, thyme, and bay leaf inside the unstuffed turkey. Tent the turkey with foil.
Bake for 15 minutes per pound. Uncover for the last 30 minutes of baking to get a golden brown skin and baste the Turkey with the pan juices every 10 minutes until done. Cook until internal temperature is 165°F.
