Slow-Cooked Lamb Shoulder: The Only Recipe You Need

Slow-cooked lamb shoulder is one of the most forgiving things you can cook. Unlike a leg roast — which punishes you for overcooking — a shoulder only gets better the longer it goes. Six hours at low heat and you get meat that pulls apart with two forks and makes the house smell incredible.

This is the version we’ve made dozens of times. It works.

What You Need

The lamb: A bone-in lamb shoulder, around 2–2.5kg. The bone is important — it adds flavour and keeps the meat moist. Ask your butcher for a shoulder, not a leg.

The aromatics: Garlic, rosemary, anchovies (optional but worth it), lemon zest, olive oil, salt.

The braising liquid: A cup of white wine, a cup of chicken stock, and a handful of sliced onion underneath the lamb.

The Recipe

1. Make the paste (night before if you can): Blitz together 6 garlic cloves, 2 tbsp fresh rosemary, 4 anchovy fillets, the zest of one lemon, and a good pour of olive oil into a rough paste. Season with salt and black pepper.

2. Score the lamb: Make deep cuts across the top of the shoulder — 10 to 12 cuts, each about 2cm deep. Push the paste into every cut and rub the rest all over the surface. If doing this the night before, wrap and refrigerate overnight.

3. Set up the tray: Scatter sliced onion across a large roasting tray. Pour in the wine and stock. Place the lamb on top — the liquid should come up about 1cm around the sides but not submerge the meat.

4. Cook low and slow: Cover tightly with foil (or a lid if your roasting dish has one) and place in an oven preheated to 160°C (140°C fan). Cook for 5 hours. Remove the foil and cook for another 45 minutes to an hour to get colour on the top.

5. Rest, then pull: Remove from the oven and rest, loosely covered, for 20 minutes. Then pull the meat apart with two forks — it should offer almost no resistance. Discard the bone.

What to Serve It With

Flatbreads and yoghurt is the move if you want something casual. For a Sunday lunch crowd, roasted potatoes and a simple green salad alongside the pan juices (strained and reduced slightly on the stovetop) works well.

The pulled meat also reheats perfectly the next day — better, even, once the juices have redistributed overnight.

The Anchovy Question

If you’ve never cooked anchovies into a lamb roast, this is the technique to try. They don’t make it taste fishy — they dissolve completely and add a deep, savoury quality that’s hard to identify but immediately noticeable. Don’t skip them.

Timing for a Sunday Lunch

Put it in at 7am for a 1pm lunch. That’s it.
