Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Peel and dice the sweet potato into 1/2-inch cubes and slice the carrots into rounds to ensure even cooking.
Place the chicken breast, sweet potatoes, carrots, and broccoli florets on the prepared baking sheet.
Drizzle the extra virgin olive oil over the chicken and vegetables.
Evenly sprinkle the dried rosemary, thyme, garlic powder, sea salt, and black pepper over everything.
Toss the ingredients thoroughly with your hands or tongs to ensure every piece is well-coated in oil and spices.
Spread the mixture into a single layer, ensuring the chicken has enough space to roast properly.
Bake 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 keep it juicy.
