01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper or aluminum foil.
02 - In a small bowl, combine 2 tablespoons olive oil, minced garlic, thyme, rosemary, oregano, salt, pepper, and lemon zest. Mix until a fragrant paste forms.
03 - Pat the chicken breasts dry with paper towels. Rub the herb mixture evenly over all sides of each breast, ensuring full coverage.
04 - Place the seasoned chicken breasts on one half of the prepared baking sheet, spacing them evenly to allow proper air circulation.
05 - Lay the trimmed asparagus on the other half of the baking sheet. Drizzle with 1 tablespoon olive oil, season with salt and pepper, and toss gently to coat.
06 - Roast in the preheated oven for 20–25 minutes, until the chicken reaches an internal temperature of 165°F and the asparagus is tender with lightly browned tips.
07 - Transfer the chicken and asparagus to serving plates. Squeeze fresh lemon wedges over the top and garnish with chopped parsley if desired. Serve immediately.
