Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Finely mince the garlic cloves and roughly chop the fresh rosemary and thyme leaves.
Peel the carrot and slice it into thin rounds, slice the zucchini into half-moons, and break the broccoli into bite-sized florets.
In a large mixing bowl, combine the chicken breast, broccoli, carrots, and zucchini.
Drizzle the olive oil over the mixture, then add the minced garlic, rosemary, thyme, sea salt, and black pepper.
Toss everything thoroughly until the chicken and vegetables are evenly coated in the oil and aromatics.
Spread the mixture in a single layer on the prepared sheet pan, ensuring the chicken is not crowded by the vegetables.
Roast for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender and slightly caramelized.
Remove from the oven and let the chicken rest for 5 minutes before slicing to ensure it stays moist and flavorful.
