Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Pat the chicken breast dry with a paper towel and cut it into 1-inch bite-sized pieces for even cooking.
Prepare the vegetables by cutting the broccoli into florets, the carrots into coins, and the zucchini into half-moons.
In a large mixing bowl, toss the chicken, broccoli, carrots, and zucchini with the extra virgin olive oil until every piece is well-coated.
Add the minced garlic, dried rosemary, dried thyme, sea salt, and black pepper to the bowl, tossing again to distribute the aromatics.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the chicken and vegetables aren't overcrowded.
Roast for 20-25 minutes, or until the chicken is cooked through and the vegetables are tender with slightly caramelized edges.
Serve immediately while the herbs are fragrant and the chicken is juicy.
