Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Wash and halve the baby potatoes, and trim the tough woody ends off the asparagus spears.
In a small 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 asparagus in a large mixing bowl and pour the herb oil over them, tossing thoroughly to ensure everything is evenly coated.
Spread the ingredients out in a single layer on the prepared baking sheet, ensuring the chicken has enough space to crisp up.
Roast for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender and golden brown.
Remove from the oven and let the chicken rest for 5 minutes before slicing and serving alongside the roasted vegetables.
