Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Halve the baby potatoes and trim the tough, woody ends off the asparagus spears.
In a small mixing bowl, whisk together the extra virgin olive oil, minced garlic, dried rosemary, dried thyme, sea salt, black pepper, lemon juice, and lemon zest.
Place the chicken breast, halved potatoes, and trimmed asparagus onto the prepared baking sheet in a single layer.
Drizzle the lemon-herb oil over the chicken and vegetables, using your hands or a brush to ensure everything is evenly coated.
Roast in the center of the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are golden and fork-tender.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
