Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Mince the garlic cloves finely and chop the red bell pepper into bite-sized chunks.
In a small mixing bowl, whisk together the extra virgin olive oil, minced garlic, dried rosemary, dried thyme, sea salt, and black pepper.
Place the chicken breast, broccoli florets, chopped bell pepper, and sliced carrots onto the prepared sheet pan.
Drizzle the garlic-herb oil mixture over the chicken and vegetables, tossing thoroughly with your hands or tongs to ensure everything is well-coated.
Arrange the ingredients in a single layer, making sure the chicken is not covered by the 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 with slightly browned edges.
Remove from the oven and let the chicken rest for 5 minutes before slicing to ensure it stays moist and flavorful.
