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, chopped rosemary, thyme, lemon zest, salt, and pepper. Toss until evenly coated.
03 - Spread the seasoned vegetables in a single layer on the prepared sheet pan. Roast for 20 minutes until slightly tender.
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.
06 - Return to the oven and roast for 18-20 minutes, flipping lamb chops halfway through cooking. Cook until lamb reaches desired doneness (medium-rare registers 130-135°F internally) and vegetables are tender.
07 - Transfer to a serving platter or plate directly from the sheet pan. Garnish with fresh chopped parsley and additional lemon wedges if desired.
