How to Make Lamb Rogan Josh with Vivek Singh
This authentic Lamb Rogan Josh is a Kashmiri classic that literally translates to 'red juice' in Hindi. Vivek Singh shares his recipe for tender lamb shanks gently braised with whole spices, onions, ginger-garlic paste, and yoghurt, creating a rich, aromatic sauce. The distinctive red colour traditionally comes from rattan jyoth bark, but beetroot provides an excellent substitute. This slow cooker adaptation retains all the warmth and complexity of the original whilst being even more convenient for home cooks. Perfect for a special dinner or celebratory meal

Method
- 1
Pat the cut lamb shank pieces dry with kitchen paper and set aside.
~5 minsTip: Drying the meat helps it brown properly and develop a good crust.
- 2
Heat the oil or ghee in a large heavy-based frying pan or casserole dish over a high heat. Add the crushed black cardamom pods, cinnamon sticks, and black peppercorns. Stir over the heat for about 30 seconds until the spices release their aromas into the oil.
~2 minsTip: Do not let the spices burn. The blooming of spices in hot fat is essential for flavour.
- 3
Add the lamb shank pieces and salt to the pan. Sear over a high heat for about 10 minutes, turning frequently, until the meat is browned on all sides. Work in batches if necessary to avoid overcrowding the pan.
~10 minsTip: This browning step develops deep flavour through the Maillard reaction. Do not skip this step even though it's a slow cooker recipe.
- 4
Reduce the heat to medium-low. Add the finely chopped onions to the pan and cook, stirring frequently, for about 5 minutes until softened and beginning to turn golden.
~5 minsTip: The onions should be translucent and fragrant.
- 5
Stir in the Ginger and Garlic Paste and cook for 2-3 minutes, stirring constantly, until fragrant and the raw smell of garlic disappears.
~3 minsTip: Watch carefully to prevent burning.
- 6
Add the Kashmiri chilli powder, ground coriander seeds, ground ginger, ground fennel seeds, and garam masala. Stir well to coat the meat and onions, cooking for about 2 minutes until the spices are fragrant.
~2 minsTip: The powdered spices will mix with the oil to form a paste.
- 7
Pour in the yoghurt and stir well, scraping any browned bits from the bottom of the pan. Cook, stirring occasionally, for about 3-4 minutes to allow the yoghurt to blend into the spice mixture.
~4 minsTip: This helps the yoghurt fully integrate rather than curdle.
- 8
Add the lamb stock or water and stir well. Bring everything to a gentle simmer, then transfer to your slow cooker. Alternatively, if using a heavy casserole dish, cover with a lid.
~5 minsTip: For slow cooker method, transfer the entire contents now. For stovetop-to-slow-cooker transition, ensure the liquid is simmering gently before transferring.
- 9
Cook on LOW for 8 hours or on HIGH for 5 hours. The meat should be very tender and falling from the bone.
~8 hrsTip: Slow cooking allows the tough cuts of lamb to become incredibly tender. Do not lift the lid unnecessarily during cooking as it extends cooking time.
- 10
About 30 minutes before the end of cooking time, stir in the cream. Let it heat through gently.
~1 minTip: Adding cream at the end rather than at the start preserves its delicate flavour and helps avoid separation.
- 11
Just before serving, scatter over the fresh chopped coriander. If desired, make the tempering: heat the ghee in a small pan, add the crushed beetroot (or rattan jyoth bark if you can find it), cook for 30 seconds to infuse the ghee, then pour over the curry for extra colour and aroma.
~2 minsTip: The tempering is traditional and adds a lovely finishing touch, but the curry is excellent without it. The beetroot provides both colour and a subtle earthiness.

Frequently Asked Questions
Absolutely. Shoulder, leg, or breast cuts work equally well. Ask your butcher for pieces roughly 5 cm across and expect to reduce the slow cooker cooking time by 1-2 hours for smaller, more tender cuts. The traditional rogan josh is also delicious made with mutton or goat, which provide a richer flavour, though goat may require an extra hour on LOW
