Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Mince the garlic cloves and finely chop the fresh rosemary and thyme leaves.
Cut the gold potato into 1-inch cubes and trim the tough, woody ends off the asparagus spears.
In a large mixing bowl, combine the chicken breast, potato cubes, minced garlic, rosemary, thyme, olive oil, sea salt, and black pepper.
Toss everything thoroughly until the chicken and potatoes are evenly coated in the herb oil.
Spread the chicken and potatoes onto the prepared baking sheet in a single layer, ensuring they aren't overcrowded.
Roast for 15 minutes, then remove the tray and add the asparagus spears, tossing them quickly in the juices on the pan.
Return to the oven and roast for an additional 10 to 12 minutes until the chicken reaches an internal temperature of 165°F and the potatoes are golden.
Let the chicken rest for 5 minutes before slicing to keep it juicy, then serve immediately with the roasted vegetables.
