Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
Wash and halve the baby potatoes, and trim the tough, woody ends off the asparagus spears.
In a small mixing bowl, whisk together the extra virgin olive oil, lemon juice, lemon zest, minced garlic, rosemary, thyme, sea salt, and black pepper.
Place the chicken breast, halved potatoes, and asparagus on the prepared sheet pan in a single layer.
Drizzle the lemon-herb oil mixture over the chicken and vegetables, tossing them gently to ensure everything is well-coated.
Roast in the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender and lightly browned.
Remove from the oven and let the chicken rest for 5 minutes before slicing to ensure it stays juicy and flavorful.
