Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Wash and halve the baby potatoes, and slice the carrot into half-inch thick rounds.
Trim the broccoli into bite-sized florets, ensuring they are uniform in size for even cooking.
Place the chicken breast, halved potatoes, carrot rounds, and broccoli florets onto the prepared sheet pan.
Drizzle the extra virgin olive oil over the chicken and the vegetable mixture.
Evenly sprinkle the dried rosemary, dried thyme, garlic powder, sea salt, and black pepper over all components on the pan.
Toss the vegetables and coat the chicken thoroughly using tongs or your hands to ensure the seasoning is well-distributed.
Arrange everything in a single layer, placing the chicken breast in the center of the pan for optimal heat circulation.
Roast for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender.
Remove from the oven and allow the chicken to rest for 5 minutes before slicing to keep the meat juicy.
