Preheat your outdoor grill or grill pan to medium-high heat and preheat the oven to 400°F.
Mince the garlic and finely chop the fresh rosemary and thyme.
In a small bowl, whisk together 0.25 tbsp of olive oil, the minced garlic, rosemary, thyme, lemon juice, sea salt, and black pepper.
Rub the herb mixture thoroughly over all sides of the lamb chops and let them marinate at room temperature for 10 minutes.
Place the asparagus spears on a baking sheet, drizzle with the remaining 0.25 tbsp of olive oil, and toss to coat evenly.
Roast the asparagus in the oven for 12-15 minutes until tender and slightly charred at the tips.
While the asparagus roasts, place the lamb chops on the hot grill and cook for 4-5 minutes per side for medium-rare, or until your desired doneness is reached.
Transfer the lamb chops to a plate and let them rest for 5 minutes to allow the juices to redistribute.
Serve the grilled lamb chops alongside the roasted asparagus for a clean and satisfying dinner.
