Marinate the Lamb: In a bowl, mix olive oil, garlic, rosemary, thyme, parsley, lemon zest, salt, and pepper. Rub the mixture over the lamb chops. Cover and marinate for at least 30 minutes or up to overnight in the refrigerator.
Prepare the Vegetables: Preheat oven to 425°F (220°C). Toss chopped vegetables with olive oil, balsamic vinegar, salt, and pepper on a baking sheet. Spread in a single layer and roast for 25–30 minutes, flipping halfway through.
Sear the Lamb: Heat a cast iron skillet over medium-high heat. Sear the lamb chops for 2– 3 minutes per side, until they are browned. Then transfer the skillet to the oven and roast for 5– 7 minutes, depending on your desired doneness.
Rest the Meat: Remove the lamb from the oven and let it rest for 5 minutes before serving, allowing the juices to redistribute.
Serve: Plate lamb chops alongside roasted vegetables and garnish with fresh herbs or lemon wedges if desired.
