Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Wash and halve the baby potatoes, and trim the tough, woody ends off the asparagus spears.
Finely mince the garlic cloves and roughly chop the fresh rosemary and thyme leaves.
In a small mixing bowl, whisk together the extra virgin olive oil, minced garlic, rosemary, thyme, sea salt, and black pepper.
Place the chicken breast, halved baby potatoes, and asparagus onto the prepared sheet pan.
Drizzle the garlic-herb oil over the chicken and vegetables, tossing them well to ensure every piece is evenly coated.
Arrange the ingredients in a single layer on the pan, placing the chicken breast in the center surrounded by the vegetables.
Roast in 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 immediately squeeze the fresh lemon juice over the entire pan to brighten the savory flavors before serving.
