01 - Preheat the oven to 400°F. Line a rimmed sheet pan with parchment paper or foil to facilitate cleanup.
02 - In a small bowl, combine olive oil, lemon zest, lemon juice, minced garlic, rosemary, thyme, salt, and black pepper. Rub the mixture thoroughly over the turkey breast, including beneath the skin where accessible.
03 - In a large bowl, toss carrots, baby potatoes, and red onion with olive oil, salt, and black pepper until evenly coated. Spread the seasoned vegetables across the prepared sheet pan.
04 - Place the turkey breast skin side up in the center of the vegetables on the sheet pan.
05 - Roast in the preheated oven for 50 to 60 minutes, or until the internal temperature of the turkey breast reaches 165°F and the vegetables are tender. Toss the vegetables halfway through cooking to ensure even roasting.
06 - Remove from oven and allow the turkey breast to rest for 10 minutes before slicing. Serve the sliced turkey alongside the roasted vegetables. Optionally, garnish with a fresh squeeze of lemon juice.
