Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
Mince the garlic cloves and chop the bell pepper and carrot into bite-sized pieces.
In a large bowl, whisk together the olive oil, minced garlic, rosemary, thyme, sea salt, and black pepper.
Add the chicken breast, broccoli florets, bell pepper, and carrot to the bowl, tossing thoroughly until everything is evenly coated in the herb oil.
Spread the chicken and vegetables in a single layer on the prepared sheet pan, ensuring they aren't overcrowded to allow for proper roasting.
Roast for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender and slightly caramelized.
Let the chicken rest for 5 minutes before slicing to keep it juicy, then serve alongside the roasted vegetables.
