Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Prepare the vegetables by cutting the broccoli into bite-sized florets, slicing the carrots into thin rounds, and dicing the zucchini into half-moons.
Place the chicken breast in the center of the baking sheet and arrange the prepared vegetables in a single layer around it.
Drizzle the extra virgin olive oil evenly over the chicken and the vegetables.
Sprinkle the dried thyme, dried rosemary, garlic powder, sea salt, and black pepper over everything on the tray.
Toss the vegetables with tongs to ensure they are well-coated in oil and spices, and flip the chicken once to season both sides.
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 with lightly caramelized edges.
Remove from the oven and let the chicken rest for 5 minutes before slicing it into strips to serve alongside the roasted vegetables.
