Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Pat the chicken breast dry with a paper towel and slice it into 1-inch bite-sized pieces to ensure even cooking.
Slice the carrots into thin rounds, cut the zucchini into half-moons, and break the broccoli into small, uniform florets.
In a large mixing bowl, combine the chicken pieces, vegetables, minced garlic, rosemary, thyme, sea salt, pepper, and extra virgin olive oil.
Toss everything thoroughly until the chicken and vegetables are well-coated with the oil and aromatics.
Spread the mixture in a single layer on the prepared baking sheet, ensuring nothing is overcrowded so the vegetables roast rather than steam.
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 vegetables are tender.
Remove from the oven and let the dish rest for 3 minutes before serving to allow the juices to redistribute.
