Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Peel the carrots and slice them into half-inch rounds, then break the broccoli into bite-sized florets.
Mince the garlic cloves finely.
Place the chicken breast, broccoli florets, and carrot rounds onto the prepared sheet pan.
Drizzle the extra virgin olive oil over the chicken and vegetables, then sprinkle with the minced garlic, dried rosemary, dried thyme, sea salt, and black pepper.
Use your hands or tongs to toss everything together until the chicken and vegetables are thoroughly and evenly coated in the oil and seasonings.
Spread the ingredients out into a single layer, ensuring the chicken has space around it to roast properly.
Bake 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 lightly browned.
Remove from the oven and let the chicken rest for 5 minutes before slicing to ensure it remains juicy and flavorful.
