Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Peel the sweet potato and cut into half-inch cubes, then slice the carrot into quarter-inch rounds.
Place the chicken breast, sweet potato cubes, carrot rounds, and broccoli florets onto the prepared sheet pan.
Drizzle the extra virgin olive oil over the chicken and vegetables.
Evenly sprinkle the dried rosemary, dried thyme, garlic powder, sea salt, and black pepper over everything.
Toss the vegetables with your hands or tongs to ensure an even coating of oil and spices, then flip the chicken to coat both sides.
Spread the ingredients out into a single layer to ensure even roasting.
Roast for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
