Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Scrub the Yukon Gold potato well and dice into uniform 1-inch cubes to ensure even cooking.
Pat the chicken breast completely dry with a paper towel and place it in a large mixing bowl along with the diced potatoes.
Drizzle the extra virgin olive oil over the chicken and potatoes, then sprinkle with the dried rosemary, thyme, garlic powder, sea salt, and black pepper.
Toss the ingredients thoroughly with your hands or a spatula until every piece is evenly coated in the oil and herb mixture.
Spread the chicken and potatoes onto the prepared baking sheet in a single layer, making sure they are not crowded so they roast rather than steam.
Place in the oven and roast for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender.
Remove from the oven and allow the chicken to rest for at least 5 minutes on a cutting board to lock in the juices before slicing.
Garnish the dish with freshly chopped parsley and serve warm.
