In Puglia, lamb is not merely roasted. It is transformed alongside the potatoes that share its pan. The potatoes are not a side dish. They are not an accompaniment. They are the silent beneficiaries of everything the lamb releases as it cooks: fat, juices, the essence of rosemary, the whisper of garlic. By the time the dish emerges from the oven, the potatoes have become something that no amount of butter or cream could replicate.

This is peasant cooking elevated by restraint. There is olive oil, good and green. There is rosemary because it grows wild on the Pugliese hills. There is garlic, used properly, which means lightly crushed cloves that flavor without overwhelming. And there is time.

The lamb must be bone-in. Boneless lamb is convenient for the cook and disastrous for the dish. The bones release gelatin and flavor that no boneless cut can provide. When you pull the meat from the bone and it separates without resistance, when the potatoes are golden and creamy and saturated with rendered fat, you will understand why this dish has been made the same way for generations.

Agnello al forno traces to the shepherding traditions of Puglia and the Mezzogiorno, where lamb was the meat of celebrations, particularly Easter. Farm families roasted the whole animal in communal wood-fired ovens, the potatoes scattered beneath to catch the drippings. The dish remains the centerpiece of Easter Sunday tables throughout Southern Italy.

The technique, the tradition, and the story behind every dish.

Equipment Needed

  • Large roasting pan or heavy baking dish
  • Meat thermometer (optional, for those who do not trust their eyes)

Instructions

  1. 1

    Prepare the lamb

    Remove the lamb from the refrigerator one hour before cooking. Cold meat does not brown properly. Pat each piece thoroughly dry with paper towels. Season generously with salt and pepper on all sides. The salt should be visible.

    Ask your butcher to cut the shoulder into pieces with the bone still attached. The bone releases gelatin and flavor as it roasts. Boneless lamb is a different dish entirely.
  2. 2

    Prepare the potatoes

    Place the potato wedges in a large bowl. Toss with half the olive oil and season with salt and pepper. The potatoes should glisten but not swim. Set aside while you preheat the oven to 425°F.

  3. 3

    Arrange for roasting

    Choose a roasting pan or large baking dish that holds everything in a single layer with the pieces touching but not crowded. Scatter the potatoes across the bottom. Nestle the lamb pieces on top of and among the potatoes. Tuck the crushed garlic cloves and rosemary sprigs throughout. Drizzle the remaining olive oil over the lamb.

  4. 4

    Roast at high heat

    Place the pan in the hot oven. Roast for 30 minutes without opening the door. The lamb should begin to brown and the fat should start rendering. The kitchen will smell of rosemary and lamb.

    Every time you open the oven door, you lose heat and extend the cooking time. Resist the temptation to peek.
  5. 5

    Add wine and continue roasting

    Remove the pan from the oven. Pour the wine over the lamb and potatoes. Use a spoon to baste the potatoes with the accumulated fat and juices. The potatoes on the bottom are beginning their transformation. Return the pan to the oven, reduce the heat to 375°F, and roast for 45 minutes more.

  6. 6

    Turn and finish

    Remove the pan again. Turn the lamb pieces to expose new surfaces to the heat. Stir the potatoes gently, moving those on the edges toward the center and vice versa. Every potato should spend time in the rendered fat. Return to the oven and roast until the lamb is deeply browned and tender, and the potatoes are golden and creamy within, 30 to 45 minutes more. The meat should pull easily from the bone.

  7. 7

    Rest and serve

    Remove from the oven and let the dish rest for 10 minutes. This is not optional. The juices redistribute and the potatoes continue to absorb the fat. Serve directly from the roasting pan, making certain everyone receives both lamb and an abundance of potatoes. The potatoes are the point.

Chef Tips

  • Lamb shoulder has more fat and connective tissue than leg, which means more flavor and a more forgiving roast. Leg works but requires more attention to avoid drying out.
  • Waxy potatoes hold their shape while absorbing fat. Starchy potatoes like russets fall apart. Use Yukon Gold, red potatoes, or fingerlings.
  • Do not crowd the pan. Crowded meat steams. Crowded potatoes become soggy. Use two pans if necessary.
  • The dish can rest, loosely covered, for up to 20 minutes. The potatoes continue to improve. The lamb stays warm longer than you expect.

Advance Preparation

  • The lamb can be seasoned up to 24 hours ahead and refrigerated uncovered. The salt draws moisture to the surface, which then reabsorbs, seasoning the meat throughout.
  • The potatoes can be cut and held in cold water for several hours. Drain and dry them thoroughly before tossing with oil.
  • Leftovers reheat adequately in a 350°F oven, covered, for 20 minutes. The potatoes will be softer but still delicious.
