Preheat your oven to 200°C and line a large baking sheet with parchment paper.
Prepare the vegetables by slicing the carrots into thin rounds and chopping the red bell pepper into bite-sized pieces.
Place the chicken breast, broccoli florets, carrots, and bell peppers onto the prepared baking sheet.
Drizzle the extra virgin olive oil over the chicken and vegetables.
Evenly sprinkle the dried rosemary, dried thyme, garlic powder, sea salt, and black pepper over everything.
Toss the vegetables and coat the chicken thoroughly with the oil and spice mixture to ensure maximum flavor.
Arrange the ingredients in a single layer, ensuring the chicken has enough space to roast evenly.
Bake for 20 to 25 minutes, or until the chicken reaches an internal temperature of 74°C and the vegetables are tender and slightly caramelized.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
Plate the sliced chicken alongside the roasted vegetables and serve immediately.
