Preheat your oven to 400°F (200°C) and line a large rimmed sheet pan with parchment paper for easy cleanup.
Halve the baby potatoes and slice the carrots into half-inch thick rounds, ensuring they are uniform for even cooking.
In a small mixing bowl, whisk together the extra virgin olive oil, minced garlic, dried rosemary, dried thyme, sea salt, and black pepper.
Place the chicken breast, halved potatoes, sliced carrots, and broccoli florets onto the prepared sheet pan.
Drizzle the garlic-herb oil over the chicken and vegetables, using your hands or a brush to ensure every piece is thoroughly coated.
Roast in the center of the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender.
Remove from the oven and let the chicken rest for 5 minutes before slicing; garnish the entire dish with fresh chopped parsley.
