Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Wash and scrub the yellow potato, then dice it into 1/2-inch cubes to ensure even roasting.
Trim the woody ends off the asparagus spears and set them aside.
In a small bowl, whisk together the extra virgin olive oil, lemon juice, lemon zest, chopped rosemary, and thyme.
Place the potato cubes on one side of the sheet pan, drizzle with half of the herb-oil mixture, and sprinkle with half of the salt and pepper.
Toss the potatoes to coat and roast in the oven for 10 minutes.
While potatoes roast, season the chicken breast with the remaining salt and pepper.
Remove the pan from the oven, place the chicken breast and asparagus on the other side, and drizzle everything with the remaining herb-oil mixture.
Return the pan to the oven and roast for an additional 15 to 20 minutes, or until the chicken reaches an internal temperature of 165°F.
Let the chicken rest for 5 minutes before slicing to ensure it stays juicy and flavorful.
