Tender lamb gets a sweet-tart kick from a sauce of orange and oregano. Ask your butcher to french the racks (remove the meat and fat from the first few inches of bone) for a clean presentation. See How to Carve a Rack of Lamb


  • 2 racks of lamb (8 ribs each), frenched

  • Coarse salt and freshly ground pepper

  • ½ cup plus 3 tablespoons extra-virgin olive oil

  • 3 pounds fingerling potatoes

  • ½ cup coarsely chopped fresh flat-leaf parsley

  • 1 large shallot, minced

  • ¼ cup red-wine vinegar

  • 3 tablespoons coarsely chopped fresh oregano

  • 1 tablespoon minced garlic

  • 1 teaspoon finely grated orange zest, plus ⅓ cup fresh orange juice

  • ½ teaspoon crushed red-pepper flakes


  1. Preheat oven to 425 degrees. Season lamb with salt and pepper. Heat a large skillet over high heat. Add 1 tablespoon oil. Sear lamb on both sides until deeply golden, 4 to 5 minutes.

  2. Transfer racks to a rimmed baking sheet, fat side up. Toss potatoes with 2 tablespoons oil, and season with salt and pepper. Arrange potatoes around lamb.

  3. Roast until an instant-read thermometer inserted into the center of the lamb reaches 130 degrees (medium-rare), 20 to 25 minutes. Transfer racks to a cutting board. Return potatoes to oven. Roast until tender, about 15 minutes more.

  4. Combine remaining 1/2 cup oil, the parsley, shallot, vinegar, oregano, garlic, orange zest and juice, red-pepper flakes, and 1/2 teaspoon salt. Spoon some sauce over lamb. Carve lamb into individual chops, slicing between ribs. Serve with potatoes and remaining sauce.
