Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
In a small mixing bowl, whisk together the extra virgin olive oil, fresh lemon juice, lemon zest, minced garlic, chopped rosemary, and chopped thyme.
Place the chicken breast on one side of the sheet pan and the trimmed asparagus spears on the other side.
Drizzle the lemon-herb oil mixture over both the chicken and the asparagus, using your hands or a brush to ensure the chicken is fully coated and the asparagus is tossed well.
Evenly sprinkle the sea salt and black pepper over the chicken and vegetables.
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 asparagus is lightly browned and tender.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
Serve the sliced chicken alongside the roasted asparagus, drizzling any remaining pan juices over the top.
