Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Dice the sweet potato into 1-inch cubes and slice the carrots into rounds to ensure they cook at the same rate as the chicken.
In a small bowl, whisk together the extra virgin olive oil, minced garlic, dried rosemary, dried thyme, sea salt, and black pepper.
Place the chicken breast, sweet potato cubes, carrots, and broccoli florets on the prepared sheet pan in a single layer.
Drizzle the herb oil mixture over the chicken and vegetables, tossing everything thoroughly with your hands to ensure an even coating.
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.
Remove from the oven and let the chicken rest for 5 minutes before slicing it into strips.
Garnish the entire plate with freshly chopped parsley and serve immediately while hot.
