01 - Preheat the oven to 425°F. Line a large sheet pan with parchment paper or foil for easy cleanup.
02 - In a large bowl, combine the halved baby potatoes, carrot sticks, and red onion wedges with 2 tablespoons olive oil, half the minced garlic, chopped rosemary, thyme, lemon zest, salt, and pepper. Toss thoroughly to coat evenly.
03 - Spread the seasoned vegetables evenly across the prepared sheet pan. Roast in the preheated oven for 20 minutes to begin the cooking process.
04 - While vegetables roast, pat the lamb chops completely dry with paper towels. Rub the chops with remaining 1 tablespoon olive oil, remaining minced garlic, additional rosemary, thyme, lemon juice, salt, and pepper on both sides.
05 - Remove the sheet pan from the oven. Arrange the seasoned lamb chops and trimmed asparagus among the partially roasted vegetables, arranging them in a single layer.
06 - Return the pan to the oven and roast for an additional 18-20 minutes. Flip the lamb chops halfway through cooking. Continue until lamb reaches desired doneness and vegetables are tender when pierced with a fork.
07 - Transfer the sheet pan meal to a serving platter or serve directly from the pan. Garnish with freshly chopped parsley and additional lemon wedges if desired.
