01 - Set oven temperature to 425°F. Line a large sheet pan with parchment paper or aluminum foil for ease of cleanup.
02 - In a small bowl, blend olive oil, kosher salt, freshly ground black pepper, thyme, rosemary, lemon zest, and minced garlic to form a flavorful marinade.
03 - Dry the turkey breast thoroughly with paper towels. Evenly coat the turkey breast with the marinade, ensuring coverage beneath the skin when possible.
04 - Toss halved baby potatoes, sliced carrots, and red onion wedges with olive oil, kosher salt, and black pepper in a large mixing bowl.
05 - Distribute the seasoned vegetables in an even layer over the prepared sheet pan. Place the turkey breast, skin side upward, nestled centrally among the vegetables.
06 - Roast in the preheated oven for 40 to 50 minutes, or until the turkey reaches an internal temperature of 165°F and the vegetables turn golden and tender.
07 - Remove the turkey from the oven and allow it to rest for 10 minutes before slicing to retain juices.
08 - Slice the turkey breast and serve alongside the roasted vegetables. Optionally, garnish with lemon wedges and fresh herbs for added brightness.
