Lamb Shank with Minted Pea Purée

Slow-braised lamb shank is a generous, cold-weather dinner centred on a tough, flavourful cut that becomes tender with time. Red wine, beef stock, garlic and rosemary create a savoury braising liquor that reduces into a glossy gravy, giving the meat depth without heavy embellishment. The minted pea purée brings a distinctly British pairing to the plate: sweet peas, fresh mint and butter cut through the richness with colour and freshness. It is well suited to relaxed entertaining or a satisfying weekend meal, with most of the cooking time left to gentle simmering.

Why this recipe works

  • Deep savoury base: Browning the lamb and softening the vegetables before braising builds a richer gravy with more depth.
  • Tender, slow-cooked lamb: A gentle braise gives the connective tissue time to soften, leaving the shank succulent and nearly falling from the bone.
  • Fresh contrast: The minted pea purée adds sweetness, brightness and herbal lift against the richness of the red wine gravy.

Timing notes

  • Mostly hands-off cooking: The active work is mainly browning, softening the vegetables and making the purée; the long braise does most of the tenderising.
  • Serve the purée fresh: The pea purée has the best colour and texture when made just before serving, while the lamb and gravy can be kept warm briefly.

Texture tips

  • For softer lamb: Keep the braise at a gentle simmer rather than a rapid boil; steady low heat helps the meat become tender without tightening.
  • For a smoother purée: Drain the peas well before blending, then loosen gradually only if needed so the purée stays bright and spoonable.
  • For glossy gravy: Reduce the braising liquid uncovered until it lightly coats a spoon, then keep it warm over low heat.

Make-ahead tips

  • Braise ahead: The lamb and gravy can be cooked in advance, chilled, then reheated gently until piping hot throughout.
  • Keep components separate: Store the lamb and gravy apart from the pea purée so each can be reheated to the right texture.
  • Freezer-friendly lamb: The lamb and gravy freeze well; thaw fully and reheat slowly, adding a little stock if the sauce has thickened too much.

Ingredient notes

  • Use bone-in shanks: Bone-in lamb shanks give the gravy body and flavour during the long braise.
  • Fresh herbs suit the finish: Fresh rosemary holds up well in the braise, while fresh mint keeps the pea purée clean, bright and aromatic.
  • Changing the wine: White wine gives a lighter result than red wine, so expect a less robust gravy even when using the same reduction step.

  1. Pat the lamb shanks dry. Heat the olive oil in a Dutch oven over medium-high heat, then brown the shanks well all over, 8 to 10 minutes in total. Transfer to a plate.
  2. Lower the heat to medium and add the onion, carrots and celery. Cook, stirring, for 6 to 8 minutes until softened and lightly golden. Add the garlic and cook for 1 minute until fragrant.
  3. Pour in the red wine and scrape up any browned bits from the base of the pot. Simmer for 3 to 4 minutes to reduce slightly. Add the beef stock and rosemary, then return the lamb shanks to the pot, nestling them into the liquid.
  4. Bring to a gentle simmer, cover with a lid and cook on low for 2 hours, turning the shanks once halfway through. They are ready when the meat is very tender and nearly falling from the bone. Transfer the shanks to a warm plate and loosely cover.
  5. Simmer the braising liquid uncovered for 10 to 15 minutes until reduced to a glossy gravy that lightly coats the back of a spoon. Taste and adjust if needed. Keep warm on low while you make the purée.
  6. Bring a saucepan of water to the boil and cook the peas for 2 to 3 minutes until bright green and tender. Drain well, then return to the pan with the butter and mint. Blend with an immersion blender until smooth, adding a splash of water only if needed to loosen.
  7. Spoon the minted pea purée onto plates and top with the lamb shanks. Ladle over the red wine gravy and serve straight away.

Recipe notes

Tips

  • For deeper flavour, brown the shanks until you have a good dark crust, then keep the heat moderate when softening the vegetables so they caramelise rather than scorch.
  • If the gravy reduces too far, loosen it with a splash of beef stock and simmer briefly to bring it back to a glossy consistency.
  • If serving vulnerable groups, ensure the lamb is cooked until piping hot throughout and the gravy is simmered thoroughly.

Substitutions

  • Replace Fresh rosemary with fresh thyme for a softer, more floral herb note.
  • Replace Red wine with dry white wine for a lighter gravy, keeping the same reduction step.
  • Replace Unsalted butter with Olive oil in the pea purée for a dairy-free finish.

Storage

  • Refrigerate up to 3 days
  • Cool the lamb and gravy quickly, then refrigerate in an airtight container. Reheat gently in a saucepan, adding a splash of beef stock if needed, until piping hot; warm the pea purée separately over low heat. Freeze the lamb and gravy for up to 3 months; the pea purée can be frozen but may need re-blending after thawing.
