Tender roasted turkey sliced and served with rich homemade gravy is a family holiday centerpiece. This lean, high protein dish is perfect for healthy eating, and leftovers make amazing sandwiches.
Preheat oven to 325°F (163°C). Remove giblets from turkey cavity. Pat turkey dry with paper towels for even browning.
Rub turkey inside and out with salt, pepper, thyme, and rosemary. Stuff the cavity with quartered onion, garlic cloves, carrot, and celery.
Place turkey breast-side up on a roasting rack in a large pan. Brush melted butter over the skin. Pour 1 cup chicken broth into the pan to keep moist.
Roast turkey, basting with pan juices every 30–45 minutes. Add the remaining cup of chicken broth halfway through roasting. Tent with foil if browning too quickly. Roast 2.5–3.5 hours, until thickest part of breast reaches 165°F.
Remove turkey and let rest at least 20 minutes before slicing. Meanwhile, skim fat from pan drippings, then heat drippings in a saucepan. Whisk in flour and cook over medium heat until golden, about 2 minutes. Gradually whisk in strained pan juices, stirring constantly for a smooth, rich gravy. Simmer until thickened and season as needed.
