How to Make Slow-Simmered Lamb Rogan Josh

Total time: 1 h 50 min · Yields 4 servings

  1. 1

    Temper the Spices

    Heat the mustard oil in a heavy-bottomed pot or Dutch oven until it reaches its smoking point. Switch off the heat for a minute to let it cool slightly, then add the black cardamom, green cardamom, cinnamon, cloves, and bay leaves. Let them sizzle for 30 seconds.

  2. 2

    Sear the Lamb

    Turn the heat back to medium-high and add the lamb cubes. Brown the meat thoroughly on all sides for about 8-10 minutes. This creates the base flavor for the gravy.

  3. 3

    Incorporate Aromatics

    Stir in the dissolved asafoetida water and salt. In a small bowl, mix the Kashmiri chili powder with two tablespoons of water to form a paste, then add it to the pot. Stir constantly for 2 minutes to cook out the raw spice smell while ensuring the chili doesn't burn.

  4. 4

    Slow Cook with Yogurt

    Lower the heat to minimum. Gradually whisk in the yogurt, ground fennel, and ground ginger. Stir continuously to prevent the yogurt from curdling. Once incorporated, add the warm water, cover tightly, and simmer on low for 60-70 minutes until the lamb is fork-tender.

  5. 5

    Final Reduction

    Remove the lid and increase the heat slightly if the gravy is too thin. Simmer until the oil (terti) separates and rises to the top, creating a rich, glossy finish.

Chef's Tips

  • Always whisk the yogurt at room temperature to ensure a smooth, non-grainy sauce.
  • If you cannot find mustard oil, use Ghee for a rich, buttery flavor profile.
  • Do not skip the fennel or ginger powder; these are the soul of a Kashmiri Rogan Josh.
  • For the best results, let the curry sit for 30 minutes before serving to allow the flavors to deepen.

What to Serve with Slow-Simmered Lamb Rogan Josh

The garlic butter sauce is the star — pick sides that soak it up or balance the richness.

  • Steamed Basmati rice
  • Butter Garlic Naan
  • Saffron-infused Pulao
  • A side of cucumber and mint Raita

Frequently asked questions

Is Rogan Josh very spicy?

Despite its bright red color, it is relatively mild. Kashmiri chili powder provides color and flavor rather than intense heat.

Can I make this in a pressure cooker?

Yes, once all ingredients are added, pressure cook for 15-18 minutes, but slow cooking yields a superior texture.

What can I substitute for lamb?

Goat meat is the most authentic substitute, but you can use beef chuck if preferred.
