Lamb Rogan Josh

An aromatic Kashmiri-style lamb curry with a deep red hue, warming spices, and a rich, slow-simmered sauce.

Ingredients

• 2 tbsp neutral oil (or ghee, if you have it)
• 1.2 kg / 2.6 lb lamb shoulder or leg, cut into 4 cm / 1.5 inch chunks
• 1 1/2 tsp kosher salt (or 1 tsp fine salt), plus more to taste
• 2 large onions, finely sliced
• 5 cloves garlic, finely grated or minced (pantry staple)
• 2 tsp fresh ginger, finely grated (optional but recommended)
• 2 tbsp tomato paste
• 1 1/2 cups plain yogurt, full-fat
• 1 1/2 cups water (or more as needed)
• 2 bay leaves
• 6 green cardamom pods, lightly crushed
• 4 cloves
• 1 black cardamom pod (optional)
• 1 cinnamon stick
• 2 tsp ground coriander
• 2 tsp ground cumin
• 2 tsp Kashmiri chili powder (or 1 tsp paprika + 1/2 tsp cayenne)
• 1 tsp smoked paprika (optional, boosts “tandoori-red” warmth)
• 1 tsp ground turmeric
• 1 tsp garam masala
• 1 tsp ground black pepper

Method

• 1

  Step 1: Brown the lamb

  Heat oil in a large heavy pot (Dutch oven ideal) over medium-high heat. Pat lamb dry, season with 1 tsp salt. Brown in 2 batches so the pot isn’t crowded, turning to get deep golden edges, about 6–8 minutes per batch. Transfer lamb to a bowl.

  Step 2: Build the base

  Lower heat to medium. Add onions with a pinch of salt and cook, stirring regularly, until deep golden-brown and sweet, 12–15 minutes (this is key to depth). Add garlic and ginger and cook until fragrant, 1 minute.

  Step 3: Bloom the spices

  Add whole spices (bay, cardamom, cloves, black cardamom if using, cinnamon). Stir 30 seconds. Add ground coriander, cumin, Kashmiri chili, turmeric, black pepper, and smoked paprika (if using). Stir constantly for 45–60 seconds until the spices smell toasted (don’t let them scorch).

  Step 4: Toast tomato paste

  Stir in tomato paste and cook for 1 minute until it darkens slightly and sticks to the pot a bit (that “frying” step adds richness).

  Step 5: Temper the yogurt (prevents splitting)

  Lower heat to low. Add yogurt 2–3 tbsp at a time, stirring well between each addition until smooth. If it looks like it might split, add a splash of water and keep stirring—low heat is your friend here.

  Step 6: Simmer low and slow

  Return lamb (and any juices) to the pot. Add 1 1/2 cups water and the remaining 1/2 tsp salt. Bring to a gentle simmer, then cover and cook on low for 1 hour 15 minutes, stirring every 20 minutes to prevent sticking.

  Step 7: Uncover and reduce

  Remove lid and simmer 20–30 minutes more, stirring occasionally, until lamb is very tender and the sauce is thick and glossy, coating the meat. Add small splashes of water if it gets too thick before the lamb is tender.

  Step 8: Finish

  Stir in garam masala and simmer 2 minutes. Taste and adjust salt and chili. Rest off heat 10 minutes (the sauce settles and thickens beautifully). Remove whole spices if you like before serving.

Tips

• **Color + heat:** Kashmiri chili gives that classic red color with gentle heat. If you only have cayenne, use much less and add paprika for color.
• **Yogurt splitting fix:** Keep heat low when adding yogurt. If it does split slightly, whisk in 2–3 tbsp water and simmer gently—flavor will still be excellent.
• **Make-ahead:** Rogan josh is even better the next day. Cool, refrigerate up to 4 days; reheat gently with a splash of water.
• **Freezing:** Freeze up to 3 months. Thaw overnight in the fridge, then reheat low and slow.
• **What to serve with:** Basmati rice, naan/roti, or simple steamed rice; a cooling yogurt on the side is perfect if you like a milder finish.
