Pat the chicken breast dry with paper towels and season lightly with salt and pepper.
Finely mince the garlic and zest the half lemon; then juice the lemon and set both aside.
Heat half of the olive oil in a non-stick skillet over medium heat.
Add the chicken breast to the skillet and cook for about 5-6 minutes on each side until golden brown and the internal temperature reaches 165°F.
In the meantime, preheat your oven to 425°F.
Place the asparagus on a baking sheet, drizzle with the remaining olive oil, and lightly season with salt and pepper.
Roast the asparagus in the preheated oven for about 10 minutes or until tender and slightly crisp.
Once the chicken is cooked, add the minced garlic and lemon zest to the pan, allowing the flavors to meld for about 1 minute.
Drizzle the lemon juice over the chicken, then plate the chicken alongside the roasted asparagus.
Serve immediately, enjoying the balance of zesty, garlicky chicken with the fresh crunch of asparagus.
