7-hour slow cooked lamb shoulder that will MELT in your mouth

Source video by Andy Cooks on YouTube. This recipe was adapted with strict source-fidelity rules and is marked for human review.

An oyster cut lamb shoulder is seared off in a hot pan with oil, then settled into the slow cooker on a bed of mirepoix, halved garlic, thyme and balsamic-deglazed pan juices. A litre of low-sodium chicken stock takes it to about three-quarters of the way up the meat, leaving the golden seared crust proud of the liquid. Seven hours on low. While the lamb finishes, banana shallots are pan-seared and finished in a hot oven with butter and balsamic. The braising liquid is strained, skimmed, reduced for around 25 minutes and tightened with a cornflour slurry. Serve family-style over mash with the shallots and a scatter of picked thyme.

Slow cooker notes: Source is already cooked in a domestic slow cooker, no adaptation required.

Ingredients

Lamb braise
  • oyster cut lamb shoulder, patted dry
  • neutral cooking oil
  • fine salt, for seasoning the lamb before searing
  • 1 carrotcarrot, sliced on the angle, unpeeled
  • onion, peeled and quartered
  • 1 headgarlic, halved across the equator
  • fresh thyme, tied in a bundle
  • balsamic vinegar, for deglazing
  • 1 Llow-sodium chicken stock
Roasted shallots
  • banana shallots, peeled with the core left intact (add late)
  • olive oil, light drizzle (add late)
  • butter (add late)
  • fresh thyme sprigs (add late)
  • balsamic vinegar (add late)
Sauce
  • cornflour, slaked in cold water (add late)

Method

  1. Pat the lamb shoulder dry and season generously with salt only (pepper burns during the sear).

    ~2 min
  2. Heat a decent amount of oil in a heavy frying pan and sear the lamb shoulder fat-side down for 10 to 15 minutes, turning to colour all sides deeply.

    ~15 min
  3. Remove the lamb, then in the same pan colour the carrot and onion, add the halved head of garlic flesh-side down and the tied thyme bundle.

    ~7 min
  4. Deglaze with balsamic vinegar, then pour the contents of the pan into the bottom of the slow cooker.

    ~1 min
  5. Sit the lamb shoulder on top of the vegetables and pour in the chicken stock to about three-quarters up the meat, leaving the golden crust proud of the liquid.

    ~2 min
  6. Lid on, slow cooker on low for 7 hours.

    ~420 min
  7. Near the end of the cook, season the peeled banana shallots with salt. Drizzle olive oil into a hot ovenproof pan, put the shallots in skin-side down for 2 to 3 minutes, then add butter and let it brown.

    ~5 min
  8. Add thyme sprigs and balsamic vinegar to the shallot pan, then move it to a 180C oven for 15 to 20 minutes, until a knife slides through but the shallots still hold their shape.

    ~20 min
  9. Lift the lamb out of the slow cooker carefully onto a tray. Pass the braising liquid through a fine sieve into a clean saucepan and skim any fat from the surface.

    ~5 min
  10. Reduce the strained liquid on a gentle boil, tasting every 5 to 6 minutes, for around 25 minutes until the seasoning sits where you want it.

    ~25 min
  11. Optional: slake cornflour in cold water, then whisk into the simmering sauce to tighten.

    ~2 min
  12. Carry the lamb to a serving dish, pour the sauce over generously, top with the roasted shallots and finish with picked thyme leaves. Serve family-style with mash.

    ~3 min

Frequently asked

Can I use a whole lamb shoulder instead of the oyster cut?
Yes. Andy Cooks suggests increasing the other ingredients by roughly half, not doubling, when stepping up to a whole shoulder.
Why low-sodium chicken stock?
The braising liquid is reduced down at the end to make the sauce. A full-salt stock will concentrate as it reduces and tip the finished sauce over the line.
I don't have a slow cooker. What's the oven equivalent?
Andy gives the oven setting as 80C in a covered pot or Dutch oven for the same long, low braise. A pressure cooker is also fine for a much shorter cook.
Extraction notes (transparency): Lamb shoulder weight not stated in the source. Oil, salt, balsamic vinegar (for the braise and the shallots), butter, cornflour, banana shallot count and onion count are not given as measured quantities. Servings inferred from lamb shoulder size and family-style framing.
