Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Wash and peel the potato and carrots, then chop the potato into 1-inch cubes and slice the carrots into half-inch thick rounds.
Mince the garlic clove finely.
Place the chicken breast, potato cubes, and carrot rounds into a large mixing bowl.
Drizzle with the extra virgin olive oil and add the minced garlic, dried rosemary, dried thyme, sea salt, and black pepper.
Toss everything thoroughly until the chicken and vegetables are evenly coated in the oil and seasonings.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the chicken has space around it to roast evenly.
Roast in the center of the oven for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
Serve the sliced chicken alongside the roasted vegetables while warm.
