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 baby potatoes, carrots, and red onion wedges with 2 tablespoons olive oil, half the minced garlic, rosemary, thyme, lemon zest, salt, and pepper. Toss until evenly coated.
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 lamb chops dry with paper towels. Rub with remaining olive oil, garlic, rosemary, thyme, lemon juice, salt, and pepper on both sides.
05 - Remove the sheet pan from the oven. Arrange lamb chops and asparagus among the partially roasted vegetables, ensuring even spacing for proper heat circulation.
06 - Return to the oven and roast for 18-20 minutes, flipping lamb chops halfway through cooking. Cook until lamb reaches desired doneness (130-135°F for medium-rare) and vegetables are tender.
07 - Transfer to a serving platter or plates. Garnish with fresh chopped parsley and additional lemon wedges if desired. Serve immediately while hot.
