01 - Preheat oven to 400°F. Line a large sheet pan with parchment paper or lightly oil it.
02 - In a small bowl, combine olive oil, lemon zest, lemon juice, minced garlic, rosemary, thyme, salt, and pepper. Rub this mixture all over the turkey breast.
03 - Arrange the turkey breast in the center of the sheet pan.
04 - In a separate bowl, toss potatoes, carrots, and red onion with olive oil, salt, and pepper. Arrange the vegetables around the turkey breast on the pan.
05 - Roast for 40–50 minutes, or until the turkey breast reaches an internal temperature of 165°F and the vegetables are tender. Stir vegetables halfway through for even roasting.
06 - Let the turkey rest for 5–10 minutes before slicing. Serve with roasted vegetables and garnish with extra lemon wedges, if desired.
