Preheat your oven to 400 degrees F and line a large sheet pan with parchment paper for easy cleanup.
Scrub the Yukon Gold potato and dice it into uniform 1-inch cubes to ensure they cook at the same rate as the chicken.
Trim the woody ends off the asparagus spears.
In a large mixing bowl, combine the chicken breast, diced potatoes, and asparagus.
Drizzle with extra virgin olive oil and lemon juice, then add the minced garlic, rosemary, thyme, sea salt, and black pepper.
Toss everything thoroughly until every piece is well-coated in the herb oil.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the chicken and potatoes aren't overcrowded.
Roast for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165 degrees F and the potatoes are tender and golden.
Let the chicken rest for 5 minutes before slicing to keep it juicy, then serve immediately.
