How to Make Slow-Roasted Lamb Rogan Josh
Total time: 1 h 50 min · Yields 4 servings
- 1
Marinate the Lamb
In a large bowl, combine the lamb chunks with the whisked yogurt, turmeric, and salt. Allow it to marinate for at least 30 minutes at room temperature, or up to 4 hours in the refrigerator for better flavor penetration.

Bloom the Whole Spices
Heat the ghee in a heavy-bottomed pot or Dutch oven over medium heat. Add the black and green cardamom, cinnamon stick, cloves, and bay leaves. Sauté for 1 minute until they become aromatic and slightly swell.

Brown the Onions and Aromatics
Add the sliced onions to the pot. Cook over medium-low heat for 15-20 minutes, stirring frequently, until they are deep golden brown. Stir in the ginger-garlic paste and cook for another 2 minutes until the raw smell disappears.

Build the Base
Add the pureed tomatoes and cook until the oil starts to separate from the sides. In a small bowl, mix the Kashmiri chili powder, coriander, fennel, ginger powder, and asafoetida with 2 tablespoons of water to form a paste. Add this paste to the pot and cook for 3 minutes.

The Slow Simmer
Increase heat to medium-high and add the lamb with its marinade. Brown the lamb for 5-7 minutes. Pour in the stock or water, bring to a boil, then reduce heat to low. Cover with a tight-fitting lid and simmer for 60-75 minutes, or until the lamb is tender and the sauce has thickened.

Finishing Touches
Once the meat is tender, check the seasoning and add salt if needed. Garnish with a generous handful of chopped cilantro and a drizzle of melted ghee before serving.
Chef's Tips
- Use Kashmiri chili powder for the bright red color without excessive heat.
- Browning the onions properly is the key to a deep, dark gravy.
- If the sauce is too thin, simmer uncovered for the last 10 minutes.
- Always whisk the yogurt before adding to prevent curdling in the heat.

Frequently asked questions
Can I use beef instead of lamb?
Yes, beef chuck or brisket works well, though cooking times may increase by 30-45 minutes.
Is Rogan Josh very spicy?
It is rich in flavor but usually mild to medium in heat due to the use of mild Kashmiri chilies.
Can I make this in a slow cooker?
Absolutely. Follow the steps up to adding the stock, then transfer everything to a slow cooker on low for 6-8 hours.
