01 - Set the oven to 425°F and prepare a large sheet pan lined with parchment paper or foil for easier clean-up.
02 - Combine 2 tablespoons olive oil, kosher salt, black pepper, thyme, rosemary, lemon zest, and minced garlic in a small bowl to form a marinade.
03 - Pat the turkey breast dry. Rub the marinade thoroughly over the entire turkey, including beneath the skin when feasible.
04 - In a large bowl, coat the baby potatoes, carrots, and red onion with 1 tablespoon olive oil, kosher salt, and black pepper. Spread them evenly on the prepared sheet pan.
05 - Place the turkey breast skin side up in the center of the vegetables on the sheet pan.
06 - Roast in the oven for 40 to 50 minutes, or until the internal temperature of the turkey reaches 165°F and the vegetables are tender and golden.
07 - Remove from oven and allow the turkey breast to rest for 10 minutes before carving.
08 - Slice the turkey and serve alongside the roasted vegetables. Optionally garnish with lemon wedges and fresh herbs.
