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 carrots into rounds and the red bell pepper into strips.
Place the chicken breast on one side of the prepared baking sheet and arrange the broccoli, carrots, and bell peppers on the other side.
Drizzle the extra virgin olive oil evenly over the chicken and the vegetable medley.
Sprinkle the dried rosemary, dried thyme, garlic powder, sea salt, and black pepper over everything.
Toss the vegetables with your hands or a spatula to ensure they are well-coated, and rub the seasonings into both sides of the chicken.
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 and slightly caramelized.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
Plate the sliced chicken alongside the roasted vegetables and serve immediately.
