Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Slice the baby potatoes into halves so they are uniform in size, and trim the woody ends off the asparagus spears.
Place the chicken breast, potatoes, and asparagus on the prepared baking sheet, ensuring they are spread out in a single layer.
Mince the garlic and finely chop the fresh rosemary and thyme.
Drizzle the extra virgin olive oil over the chicken and vegetables, then sprinkle with the minced garlic, chopped herbs, sea salt, and black pepper.
Squeeze the juice of half a lemon over the entire tray and toss gently with your hands or tongs to ensure an even coating of oil and seasoning.
Roast in the oven for 20-25 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 and flavorful.
