In a small bowl, whisk together 0.5 tablespoons of olive oil, minced garlic, rosemary, thyme, lemon juice, salt, and pepper to create the herb marinade.
Pat the lamb chops dry with a paper towel and coat them thoroughly with the herb mixture, allowing them to marinate for at least 15 minutes at room temperature.
Toss the asparagus spears with the remaining 0.25 tablespoons of olive oil and a light pinch of salt.
Preheat a grill or cast-iron grill pan over medium-high heat until it is very hot.
Place the lamb chops on the grill and sear for 3 to 4 minutes per side for medium-rare, ensuring a deep golden crust forms.
Add the asparagus to the grill during the last 5 minutes of cooking, turning occasionally until they are tender and show light char marks.
Transfer the lamb to a plate and let it rest for 5 minutes before serving to allow the juices to settle for a succulent texture.
