01 - Preheat the oven to 400°F. Line a large sheet pan with parchment paper.
02 - In a large bowl, combine olive oil, lemon juice, lemon zest, garlic, rosemary, thyme, salt, and black pepper. Add the turkey breast and coat thoroughly. Let marinate for 15 minutes or up to 2 hours in the refrigerator for enhanced flavor.
03 - In a separate bowl, toss baby potatoes, carrots, red bell pepper, zucchini, and red onion with olive oil, Italian herbs, salt, and black pepper until evenly coated.
04 - Place the vegetables in a single layer on the prepared sheet pan, leaving a space in the center for the turkey breast.
05 - Position the marinated turkey breast in the center of the vegetables on the sheet pan.
06 - Roast in the oven for 35 to 40 minutes, or until the turkey reaches an internal temperature of 165°F and the vegetables are tender and caramelized.
07 - Remove from the oven, loosely cover the turkey with foil, and let rest for 5 to 10 minutes before slicing.
08 - Slice the turkey and serve alongside the roasted vegetables. Optionally garnish with additional lemon zest or fresh herbs.
