01 - Set the oven to 350°F and allow it to reach temperature before roasting.
02 - Pat the turkey breast dry using paper towels and place it skin side up on a rack within a roasting pan.
03 - Combine olive oil, kosher salt, black pepper, garlic powder, onion powder, thyme, rosemary, paprika, lemon zest, and lemon juice in a small bowl to form a uniform paste.
04 - Rub the paste evenly over the turkey breast, coating both skin and underside thoroughly.
05 - Scatter minced garlic, quartered onion, carrot chunks, and celery around the turkey in the roasting pan. Pour the chicken broth into the pan.
06 - Roast uncovered for 60 to 75 minutes, basting once or twice with pan juices. Ensure the internal temperature reaches 165°F at the thickest point.
07 - If skin lacks golden color, increase oven temperature to 425°F and roast for an additional 10 minutes.
08 - Remove turkey from oven, tent loosely with foil, and rest for 15 minutes before carving.
