Slow Cooker Lamb Shanks with Root Vegetables Holiday Dinner — 42g Protein

This slow cooker lamb shanks with root vegetables holiday dinner is the kind of Thanksgiving main that takes care of itself. Lamb shanks brown in a hot pan, then spend five hours in the slow cooker with carrots, parsnips, onion, garlic, rosemary and red wine until the meat falls off the bone. Each serving carries 42g of protein, and the vegetables cook in the same rich gravy, so dinner lands on the table with almost no last-minute work.

The trick is the sear. Browning the shanks well before they go in the slow cooker builds the deep, savoury flavour that a long, gentle cook then turns into something silky. Skip the sear and the gravy stays flat, no matter how long it cooks.

Why you’ll love it

• 42g protein per serving, about 520 calories
• Fall-off-the-bone lamb with almost no hands-on time
• The vegetables cook in the gravy — no extra side dish needed
• A proper holiday centrepiece that frees up the oven entirely

Ingredients

• 4 lamb shanks (about 350g each), trimmed of excess fat
• 2 tbsp olive oil
• 1 tsp coarse sea salt
• 1 tsp black pepper, freshly ground
• 3 large carrots, peeled and cut into thick chunks
• 3 parsnips, peeled and cut into thick chunks
• 1 large onion, cut into wedges
• 5 garlic cloves, smashed
• 2 tbsp tomato paste
• 1 cup dry red wine
• 1 1/2 cups beef or lamb stock
• 2 tbsp balsamic vinegar
• 3 sprigs fresh rosemary
• 3 sprigs fresh thyme
• 2 bay leaves
• 2 tbsp fresh parsley, chopped, to serve

Equipment used

• A large heavy skillet, for searing the lamb shanks
• A 6-quart slow cooker, for the long gentle cook
• Tongs, for turning the shanks without tearing the meat
• A ladle, for serving the gravy over the lamb and vegetables

Instructions

1. Pat the lamb shanks dry and season all over with salt and pepper.
2. Heat the olive oil in a large skillet over high heat. Sear the shanks in batches for 3–4 minutes per side, until deeply browned all over. Transfer them to the slow cooker.
3. Lower the heat to medium. Add the onion to the skillet and cook for 3 minutes, then add the garlic and tomato paste and cook for 1 minute more.
4. Pour in the red wine and scrape up the browned bits from the bottom of the pan. Simmer for 2 minutes, then pour everything into the slow cooker.
5. Add the carrots, parsnips, stock, balsamic vinegar, rosemary, thyme and bay leaves around the shanks.
6. Cover and cook on low for 5 hours, until the lamb is tender and pulls easily from the bone. Avoid lifting the lid — every peek adds cooking time.
7. Lift the shanks and vegetables out onto a serving dish. Taste the cooking liquid and season with salt and pepper if needed.
8. Spoon the gravy over the lamb and vegetables, scatter with fresh parsley, and serve hot.

Tips

• Don’t skip the sear — it is where most of the flavour comes from, and the slow cooker can’t create it on its own.
• Keep the lid on. Slow cookers lose a lot of heat every time the lid lifts, so resist checking until the last hour.
• If the gravy is thinner than you like, pour it into a pan and simmer for 10 minutes while the lamb rests under foil.
• Leftovers keep 3 days in the fridge and taste even better the next day. Reheat gently on the hob in the gravy.

FAQ

Can I cook slow cooker lamb shanks with root vegetables holiday dinner on high? Yes, but low is better. On high it takes about 3–3.5 hours, but the meat is more tender and the gravy richer after 5 hours on low.

What if I don’t have red wine? Use extra stock plus a tablespoon of balsamic vinegar. The wine adds depth, but the dish still works without it.

Can I make this ahead? Yes. Cook it fully, cool, and refrigerate overnight in its gravy. Reheat gently on the hob or in a low oven — the flavour actually improves.

Which root vegetables work best? Carrots and parsnips hold their shape over five hours. Potatoes and sweet potatoes work too, but add them in the last 2 hours so they don’t fall apart.
