Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Prepare the vegetables by slicing the carrot into thin rounds and dicing the zucchini into half-moons.
Mince the garlic clove finely.
Place the chicken breast, broccoli florets, sliced carrots, and zucchini on the prepared sheet pan.
Drizzle the extra virgin olive oil over the chicken and vegetables, then sprinkle with the minced garlic, rosemary, thyme, sea salt, and black pepper.
Toss everything thoroughly with your hands or tongs to ensure an even coating of oil and seasoning.
Arrange the ingredients in a single layer, ensuring the chicken is not covered by vegetables so it browns properly.
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 chicken rest for 5 minutes before slicing to keep it juicy.
Serve the sliced chicken alongside the roasted vegetables while warm.
