Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
Slice the carrots into thin rounds and chop the red bell pepper into bite-sized pieces.
In a small bowl, whisk together the extra virgin olive oil, minced garlic, dried thyme, dried rosemary, sea salt, and black pepper.
Place the chicken breast, broccoli florets, sliced carrots, and bell pepper pieces on the prepared sheet pan.
Drizzle the garlic-herb oil mixture over the chicken and vegetables, tossing well to ensure everything is evenly coated.
Arrange the ingredients in a single layer, ensuring the chicken has enough space to roast properly.
Roast in the oven for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender and slightly caramelized.
Remove from the oven and let the chicken rest for 5 minutes before slicing and serving alongside the roasted vegetables.
