Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Scrub the red potato and carrots; dice the potato into 1-inch cubes and slice the carrots into 1/2-inch thick rounds.
Mince the garlic cloves and finely chop the fresh rosemary and thyme leaves.
Place the chicken breast, potato cubes, and carrot rounds on the prepared baking sheet.
Drizzle everything with extra virgin olive oil, then sprinkle with minced garlic, rosemary, thyme, sea salt, and black pepper.
Toss thoroughly with your hands or tongs to ensure every piece is evenly coated in the oil and aromatics.
Spread the ingredients into a single layer, ensuring the chicken has space around it to roast properly.
Bake for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are golden and tender.
Let the chicken rest for 5 minutes before slicing to keep it juicy, then serve alongside the roasted vegetables.
