Jamie Oliver Slow Cooker Lamb Shanks – Ingredients List

4 lamb shanks
2 onions, sliced
3 carrots, chopped
2 celery sticks, chopped
4 cloves garlic, crushed
1 × 400g can chopped tomatoes
1 tablespoon tomato paste
500ml beef stock
1 teaspoon dried rosemary
1 teaspoon dried thyme
2 bay leaves
Salt and pepper to taste
2 tablespoons olive oil

How to Prepare Jamie Oliver Slow Cooker Lamb Shanks – Simple Steps

Step 1: Brown the Lamb Shanks for Extra Flavour

Heat olive oil in a pan and brown the lamb shanks on all sides. This step boosts flavour and caramelises the edges, giving the stew depth. Transfer the browned shanks to the slow cooker.

Step 2: Sauté Vegetables to Build the Aroma

In the same pan, cook onions, carrots, celery, and garlic until soft and lightly golden. Sweating the vegetables enhances sweetness and enriches the final gravy.

Step 3: Add Tomatoes, Herbs, and Stock

Stir in tomato paste, chopped tomatoes, rosemary, thyme, and bay leaves. Pour in beef stock and bring to a gentle simmer. This mixture forms the core of the sauce and ensures the shanks stay moist during cooking.

Step 4: Slow Cook Until Tender

Pour everything into the slow cooker over the lamb shanks. Cook on LOW for 7–8 hours or HIGH for 4–5 hours until the meat is falling off the bone and the sauce has thickened naturally.

Step 5: Serve With Your Favourite Sides

Taste and adjust seasoning, then serve the lamb shanks with mashed potatoes, polenta, rice, or crusty bread. Spoon plenty of the rich gravy over each serving for the best experience.

Best Lamb Cut for Slow Cooker Lamb Shanks

Lamb shanks are ideal because the connective tissue breaks down during long cooking, turning tough fibres into soft, flaky meat full of natural gelatin and flavour.

FAQs

Can you put lamb shanks straight into the slow cooker without browning?

Yes, you can put lamb shanks directly into the slow cooker, and they will still become tender. However, browning them first adds deeper flavour and creates a richer gravy, which is why it’s recommended for the best Jamie Oliver–style result.

Why are my lamb shanks not getting tender in the slow cooker?

Lamb shanks need low and slow cooking to break down tough fibres. If they remain firm, they likely haven’t cooked long enough. Extend the cooking time by 1–2 hours on LOW until the meat begins to fall off the bone.

Can lamb shanks be overcooked in the slow cooker?

It’s uncommon but possible. Cooking on HIGH for too long can dry out the meat. Using the LOW setting for most of the cooking time ensures tender, juicy lamb shanks.
