What ingredients do you need?
Here’s what you’ll need to create this delightful slow-cooked lamb dish. I usually pick up my ingredients from Tesco or Waitrose, but any UK supermarket will do.
- Lamb Shoulder: A bone-in lamb shoulder is ideal for slow cooking, as the bone adds extra flavour. Aim for around 2kg.
- Onions: Two large red onions, roughly chopped, provide a lovely sweetness.
- Carrots: Three or four carrots, peeled and chopped, add a touch of sweetness and essential nutrients.
- Garlic: A whole bulb of garlic, halved horizontally, infuses the lamb with a subtle, aromatic flavour.
- Rosemary: Fresh rosemary sprigs are a classic pairing with lamb.
- Thyme: Fresh thyme sprigs add an earthy, herbaceous note.
- Lamb Stock: About 500ml of good quality lamb stock (or vegetable stock if you don’t have lamb stock) helps to keep the lamb moist and adds depth of flavour.
- Olive Oil: For browning the lamb.
- Salt and Pepper: To season.
How do you make it step by step?
Follow these simple steps for a guaranteed delicious slow-cooked lamb shoulder.
- Sear the Lamb: Heat a tablespoon of olive oil in a large frying pan over medium-high heat. Season the lamb shoulder generously with salt and pepper. Brown the lamb on all sides until nicely coloured. This step is crucial for developing flavour.
- Prepare the Slow Cooker: Place the chopped onions and carrots in the bottom of the slow cooker. Add the halved garlic bulb, rosemary sprigs, and thyme sprigs.
- Place the Lamb: Put the browned lamb shoulder on top of the vegetables in the slow cooker.
- Add the Stock: Pour the lamb stock over the lamb, ensuring it comes about halfway up the side of the meat.
- Slow Cook: Cover the slow cooker and cook on low for 8-10 hours, or on high for 4-5 hours. The lamb is ready when it’s falling off the bone.
- Shred the Lamb: Once cooked, remove the lamb shoulder from the slow cooker and place it on a carving board. Use two forks to shred the lamb meat.
- Make the Gravy (Optional): Strain the cooking juices from the slow cooker into a saucepan. Skim off any excess fat. Bring the juices to a simmer over medium heat. Thicken with a cornflour slurry (mix 1 tablespoon of cornflour with 2 tablespoons of cold water) until the gravy reaches your desired consistency. Season to taste.
- Serve: Serve the shredded lamb with mashed potatoes, gravy, and your favourite vegetables.
What are Emma’s tips for slow cooker lamb?
- Don’t skip the searing! Browning the lamb before slow cooking is essential for developing a rich, deep flavour. It’s worth the extra few minutes.
- Use bone-in lamb: The bone adds so much flavour to the dish. It’s worth seeking out a bone-in shoulder for the best results.
- Adjust cooking time: Slow cookers can vary, so keep an eye on the lamb towards the end of the cooking time. It’s ready when it easily pulls apart with a fork.
- Rest the lamb: If you have the time, let the lamb rest for 15-20 minutes before shredding. This allows the juices to redistribute, resulting in even more tender and flavorful meat.
- Add a splash of red wine: For an even richer flavour, add a splash of red wine to the slow cooker along with the lamb stock. A good quality Merlot or Cabernet Sauvignon works wonders.
- Vary the vegetables: Feel free to add other vegetables to the slow cooker, such as parsnips, swede, or potatoes. Just make sure to chop them into similar sizes so they cook evenly.
- Make minted gravy: For a classic pairing with lamb, add a tablespoon of chopped fresh mint to the gravy at the end of cooking. It adds a lovely fresh flavour. You could even use some mint sauce if you’re short on fresh mint!
Can you make this ahead and reheat it?
Yes. The shredded lamb can be stored in an airtight container in the fridge for up to 3 days. Reheat in the oven at 180°C / Gas Mark 4 for 20 minutes, covered with foil, or gently reheat in a saucepan on the hob.
What should you serve with it?
This slow cooker lamb shoulder is incredibly versatile and pairs well with a variety of side dishes. Here are a few of my favourites:
