Can I use a different cut of lamb for this recipe?

Lamb shoulder is ideal for slow cooking because the fat and connective tissue break down beautifully over long cooking times, giving you incredibly tender meat. Lamb leg can also work but tends to be leaner, so it may not be quite as meltingly soft. Avoid quick-cooking cuts like lamb loin or chops as they can dry out.

Can I prepare this the night before?

Absolutely! You can brown the lamb and prepare all the vegetables the evening before, then store everything in the fridge. In the morning, simply add everything to the slow cooker and switch it on. Allow an extra 15–20 minutes of cooking time as the ingredients will be cold when they go in.

The sauce is quite thin — how can I thicken it?

Slow cookers retain a lot of moisture, so this can happen. Once the lamb is cooked, you can remove the lid and switch to High for 30 minutes to reduce the liquid. Alternatively, mix 1 tablespoon of cornflour with 2 tablespoons of cold water, stir it into the pot, and cook on High for a further 15–20 minutes until thickened.

How long does leftover slow cooked lamb keep?

Leftover lamb and vegetables can be stored in an airtight container in the fridge for up to 3 days. It also freezes brilliantly for up to 3 months. Defrost fully in the fridge overnight and reheat thoroughly until piping hot all the way through.

Slow cooker adaptation notes

• This recipe has been adapted for slow cooker use based on the video title and description only — no transcript was available. • Liquid has been reduced slightly as slow cookers retain more moisture than conventional pots. • Browning the lamb before adding to the slow cooker is recommended for deeper colour and flavour. • Fresh herbs such as rosemary should be added at the start, but delicate garnish herbs like parsley should be added at the end. • Root vegetables are cut into larger chunks to prevent them from breaking down too much over a long cook.

Ingredients

Servings:

Units:

Main

1000 g lamb shoulder, bone-in, trimmed of excess fat
Bone-in shoulder gives the best flavour
2 tbsp olive oil
For browning the lamb
2 medium onions, roughly chopped
3 medium carrots, peeled and cut into large chunks
2 sticks celery sticks, roughly chopped
6 cloves garlic cloves
, peeled and lightly crushed
400 g potatoes, peeled and cut into large chunks
Waxy or all-rounder varieties work best
3 sprigs fresh rosemary
4 sprigs fresh thyme
2 tbsp tomato purée
300 ml lamb or beef stock
Reduced from typical one-pot recipe as slow cookers retain moisture
150 ml red wine
(optional)
Can be replaced with extra stock

Seasoning

1 tsp salt
Adjust to taste
½ tsp black pepper, freshly ground

Garnish

2 tbsp fresh parsley
, finely chopped(optional)
Scatter over the dish just before serving

Method

1
Season the lamb shoulder generously all over with salt and black pepper.
~2 mins
2
Heat the olive oil in a large frying pan over a high heat. Sear the lamb shoulder on all sides until deeply browned, about 3–4 minutes per side. Transfer the lamb to the slow cooker.
~10 mins
Tip: Browning adds significant flavour and colour. Don't skip this step if possible.
3
In the same pan, add the onions, carrots, and celery. Cook for 3–4 minutes over a medium heat, stirring occasionally, until slightly softened. Add the garlic and tomato purée and cook for a further minute.
~5 mins
4
Pour in the red wine (if using) and let it bubble for 1–2 minutes, scraping up any browned bits from the bottom of the pan. Add the stock and stir to combine.
~3 mins
Tip: If not using wine, simply add all the stock here.
5
Place the potatoes into the base of the slow cooker around the lamb. Pour the vegetable and stock mixture over the top. Tuck in the rosemary and thyme sprigs.
~3 mins
Tip: Placing the potatoes at the bottom ensures they cook through properly in the liquid.
6
Cover with the lid and cook on Low for 8 hours or High for 5 hours, until the lamb is completely tender and falling off the bone.
~8 hrs
Tip: Avoid lifting the lid during cooking as this releases heat and extends the cooking time.
7
Carefully remove the lamb from the slow cooker. Shred the meat using two forks, discarding any bones and excess fat. Remove and discard the herb stalks.
~5 mins
8
Return the shredded lamb to the slow cooker and stir through the vegetables and juices. Taste and adjust the seasoning as needed. Scatter with fresh parsley and serve with crusty bread or mashed potatoes.
