01 - Set the oven to 350°F (175°C).
02 - Pat the turkey breast dry with paper towels and place it skin side up on a roasting rack inside a roasting pan.
03 - Combine olive oil, kosher salt, black pepper, garlic powder, onion powder, dried thyme, dried rosemary, paprika, lemon zest, and lemon juice in a small bowl to form a paste.
04 - Rub the seasoning paste evenly over the turkey breast, coating the skin and underside thoroughly.
05 - Scatter minced garlic, quartered onion, carrot chunks, and celery around the turkey in the pan, then pour the chicken broth into the roasting pan.
06 - Roast the turkey uncovered for 60 to 75 minutes, basting once or twice with pan juices, until the internal temperature reaches 165°F (74°C) at the thickest point.
07 - If the skin is not golden brown, increase oven temperature to 425°F (220°C) and roast for an additional 10 minutes.
08 - Remove the turkey from the oven and cover loosely with foil. Let it rest for 15 minutes before slicing to retain juiciness.
