Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
In a small bowl, whisk together the extra virgin olive oil, minced garlic, dried rosemary, dried thyme, sea salt, and black pepper.
Place the chicken breast, cubed sweet potato, sliced carrots, broccoli florets, and sliced red bell pepper on the prepared sheet pan.
Drizzle the garlic-herb oil mixture over the chicken and vegetables, tossing everything thoroughly to ensure an even coating.
Arrange the ingredients in a single layer on the pan, placing the chicken breast in the center to ensure even cooking.
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 it and serving alongside the roasted vegetables.
