Preheat your oven to 425°F (220°C) and line a large sheet pan with parchment paper.
Wash and halve the baby potatoes, and trim the woody ends off the asparagus spears.
In a small bowl, whisk together the extra virgin olive oil, minced garlic, chopped rosemary, and chopped thyme.
Place the halved potatoes on one side of the sheet pan, drizzle with half of the herb oil mixture, and season with a pinch of sea salt and black pepper.
Roast the potatoes for 10 minutes to give them a head start on crisping up.
While potatoes roast, pat the chicken breast completely dry with a paper towel and season both sides with the remaining salt and pepper.
Remove the pan from the oven, move potatoes to one side, and place the chicken breast and asparagus on the other side.
Brush the remaining herb oil over the chicken and asparagus, then top the chicken with thin slices of lemon.
Return the pan to the oven and roast for 15-20 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender.
Let the chicken rest for 5 minutes before serving to ensure the juices redistribute for maximum tenderness.
