Preheat your oven to 400°F (200°C) and wash the asparagus, snapping off the tough, woody ends.
Pat the chicken breast completely dry with paper towels to ensure a crispy sear.
In a small bowl, combine the dried thyme, dried rosemary, sea salt, and black pepper.
Season both sides of the chicken breast generously with half of the herb mixture.
Heat half of the olive oil in a large oven-safe skillet over medium-high heat.
Place the chicken in the skillet and sear for 3-4 minutes per side until a golden-brown crust forms, then temporarily remove the chicken from the pan.
In the same skillet, add the remaining olive oil, asparagus, and minced garlic, tossing with the remaining herb mixture.
Place the chicken breast back into the skillet on top of the asparagus and transfer the pan to the oven.
Roast for 10-12 minutes or until the chicken reaches an internal temperature of 165°F and the asparagus is tender.
Squeeze the fresh lemon juice over the chicken and vegetables just before serving for a bright finish.
