Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Dice the sweet potato into 1/2-inch cubes and slice the carrots into coins to ensure they cook at the same rate as the chicken.
Place the chicken breast, broccoli florets, carrots, and sweet potato on the prepared baking sheet.
Drizzle the extra virgin olive oil over the chicken and vegetables, then sprinkle evenly with sea salt, black pepper, garlic powder, and dried thyme.
Toss everything together with your hands or tongs until well-coated, then spread into a single layer.
Roast in the oven for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are golden.
Let the chicken rest for 5 minutes before slicing to keep it juicy, then serve alongside the roasted vegetables.
