Preheat your oven to 400°F and line a large sheet pan with parchment paper.
Pat the chicken breast dry with a paper towel to ensure the skin gets extra crispy during roasting.
In a small bowl, whisk together the olive oil, lemon juice, lemon zest, rosemary, thyme, sea salt, and black pepper.
Place the chicken breast, broccoli, sliced carrots, and cubed sweet potato on the prepared sheet pan.
Drizzle the herb and lemon oil mixture over the chicken and vegetables, tossing the produce to coat evenly.
Roast in the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender.
Let the chicken rest for 5 minutes before slicing to keep the meat juicy and flavorful.
