Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Pat the turkey breast completely dry with paper towels to ensure the skin and surface crisp up beautifully.
In a small bowl, whisk together the dried rosemary, dried thyme, garlic powder, sea salt, and black pepper.
Coat the turkey breast with half of the olive oil, then rub the herb mixture evenly over all sides of the meat.
Prepare the vegetables by halving the Brussels sprouts and slicing the carrots into rounds, then toss them with the remaining olive oil on the baking sheet.
Nestle the turkey breast in the center of the vegetables and roast for 25 to 30 minutes, or until the internal temperature reaches 165°F.
Remove from the oven and let the turkey rest for at least 5 minutes before slicing to keep the meat succulent and juicy.
