Preheat the oven to 325°F (165°C).
Prepare the turkey by patting it dry with paper towels and removing any giblets.
Season the turkey by mixing butter, salt, black pepper, garlic powder, onion powder, paprika, thyme, rosemary, lemon juice, and minced garlic in a bowl. Rub the mixture all over the turkey, including under the skin for maximum flavor.
Stuff the cavity with the quartered onion, carrots, and celery for extra moisture and flavor.
Roast the turkey: Place it on a roasting rack in a large roasting pan. Pour the chicken broth into the pan to keep the turkey moist during cooking.
Cook uncovered for about 3 hours, basting every 30 minutes with the pan juices or additional melted butter.
Check doneness: Use a meat thermometer to ensure the thickest part of the turkey reaches 165°F (75°C).
Rest the turkey for 30 minutes before carving to allow the juices to redistribute.
Serve and enjoy!
