Preheat your oven to 400°F and line a rimmed baking sheet with parchment paper for easy cleanup.
Pat the chicken breast completely dry with paper towels to ensure the skin roasts to a perfect golden brown.
In a small glass bowl, whisk together the olive oil, minced rosemary, thyme, lemon zest, sea salt, and black pepper.
Place the chicken breast on one side of the prepared baking sheet and rub thoroughly with half of the herb-oil mixture.
Slide the chicken into the oven and roast for 15 minutes.
While the chicken is roasting, trim the woody ends off the asparagus and toss the spears with the remaining herb-oil mixture.
Remove the baking sheet from the oven, arrange the asparagus in a single layer on the empty side, and roast for an additional 10-12 minutes until the chicken reaches an internal temperature of 165°F.
Drizzle the fresh lemon juice over the entire plate before serving to enhance the aromatic herbs and bright citrus notes.
