Agnello al Forno di Pasqua (Easter Roast Lamb with Potatoes)

In Italian Easter cooking, roast lamb with potatoes is a generous centrepiece rather than a complicated showpiece: bone-in lamb, simple aromatics and the savoury richness of the roasting pan do most of the work. This version uses garlic, rosemary, lemon and extra-virgin olive oil to season the meat, while chunky potatoes roast alongside it and absorb the herby juices. A splash of dry white wine lifts the browned pan juices into a fragrant jus for serving. The result is familiar, rustic and well suited to a shared dinner, with tender lamb, crisp-edged potatoes and a clean herbal finish.

Why this recipe works

  • Classic aromatic base: Garlic, rosemary, lemon and olive oil season both the lamb and potatoes, giving the whole pan a cohesive savoury flavour.
  • Two-stage roasting: Starting hot helps brown the lamb and potatoes, then gentler roasting allows the meat to cook through without drying out.
  • Built-in side dish: The potatoes roast around the lamb, absorbing the pan juices while becoming browned at the edges.
  • Simple pan jus: White wine deglazes the roasting pan, turning the browned bits into a glossy sauce for spooning over the carved lamb.

Timing notes

  • Rest before carving: Let the lamb rest after roasting so the juices settle and the slices stay moist.
  • Mostly hands-off: The active work is mainly seasoning the lamb, preparing the potatoes and finishing the pan jus; the oven does most of the cooking.
  • Serve soon after carving: Carve once rested and spoon over the warm jus at the table for the best texture and flavour.

Ingredient notes

  • Bone-in lamb leg: A bone-in leg gives the roast structure and flavour, and suits a centrepiece-style presentation.
  • Use fresh rosemary if possible: Fresh rosemary gives a cleaner, more aromatic flavour than dried herbs in this simple roast.
  • Choose a dry wine: A dry white wine keeps the pan jus savoury and bright rather than sweet.

Common mistakes

  • Use a thermometer: Check the lamb’s internal temperature rather than relying only on time, as size and oven performance can vary.
  • Do not skip the temperature reduction: The initial high heat browns the roast, but reducing the oven helps the lamb finish more gently.
  • Avoid carving too early: Cutting into the lamb straight from the oven can cause more juices to run out onto the board.

Make-ahead tips

  • Prepare the aromatics ahead: The garlic, rosemary, lemon and oil mixture can be prepared in advance and kept chilled until needed.
  • Reheat gently: Warm leftovers in a 180°C (355°F) oven until piping hot, adding a little moisture to help protect the lamb from drying.
  • Freeze leftovers separately: Freeze sliced lamb and potatoes in separate containers for better texture, then defrost in the fridge before reheating.

  1. Heat the oven to 220°C (430°F). Pat the lamb dry and set it in a roasting pan.
  2. Cut the potatoes into chunky pieces and add them to the pan around the lamb. Lightly crush the garlic cloves, strip the rosemary leaves from the sprigs, then finely grate the lemon zest and squeeze the juice.
  3. Mix the olive oil with the garlic, rosemary, lemon zest and juice, salt, and black pepper. Rub this all over the lamb, then toss the potatoes in the oily juices in the pan.
  4. Roast for 20 minutes to brown the lamb and start crisping the potatoes. Turn the potatoes once if they are colouring quickly at the edges.
  5. Reduce the oven to 180°C (355°F) and continue roasting until the lamb is tender and a thermometer reads 60°C (140°F) for medium, or 65°C (150°F) for medium-well. Stir and turn the potatoes once or twice during roasting so they brown evenly.
  6. Transfer the lamb to a board and rest for 15 minutes; keep the potatoes warm in the switched-off oven. Carefully pour off excess fat from the roasting pan, leaving the browned bits and a little of the juices behind.
  7. Place the roasting pan over a medium heat on the hob and pour in the white wine. Scrape up the browned bits and simmer for 2 to 4 minutes until slightly reduced and glossy, then taste and adjust with a pinch more salt or pepper if needed.
  8. Carve the lamb and serve with the roast potatoes. Spoon the white wine pan jus over the lamb at the table.

Recipe notes

Tips

  • For deeper flavour, make small slits in the lamb and push in a little of the garlic and rosemary mixture before roasting.
  • If the potatoes are browning too fast before the lamb is ready, move them to the corners of the pan and turn them so the paler sides face down.
  • For food safety, cook lamb to your preferred doneness using a thermometer, and rest it so the juices redistribute before carving.

Substitutions

  • Replace Fresh rosemary with Fresh thyme for a softer, more floral herb note.
  • Replace Dry White Wine with Dry red wine for a darker, richer pan jus.

Storage

  • Refrigerate up to 3 days
  • Cool leftovers quickly, then refrigerate in a sealed container. Reheat lamb and potatoes in a 180°C (355°F) oven until piping hot; add a splash of water to the pan jus and warm gently on the hob. Freeze sliced lamb and potatoes separately for best texture, and defrost overnight in the fridge before reheating.
