Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
Mince the garlic and finely chop the fresh rosemary and thyme leaves.
Peel the carrot and slice it into half-inch rounds, and cut the red bell pepper into one-inch strips.
In a large mixing bowl, combine the chicken breast, broccoli, carrots, and bell peppers.
Drizzle with olive oil and add the minced garlic, rosemary, thyme, sea salt, and black pepper.
Toss everything thoroughly until the chicken and vegetables are evenly coated in the oil and herbs.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the chicken is not covered by vegetables.
Roast for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender and slightly browned.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
