Rogan Josh stands as one of the most beloved dishes in Indian cuisine, originating from the beautiful valleys of Kashmir. This rich, aromatic curry features tender chunks of lamb or mutton slow-cooked in a fragrant blend of spices and yogurt, creating a dish that’s both comforting and sophisticated. The name “Rogan Josh” translates to “red heat,” referring to the dish’s beautiful deep red color that comes from Kashmiri red chilies and the careful layering of spices. What makes this curry truly special is its perfect balance of warmth and richness without being overwhelmingly spicy, making it a favorite for family gatherings and special occasions.

Ingredients You’ll Need
For the main dish, you’ll need 2 pounds of lamb or mutton cut into medium chunks, preferably from the shoulder or leg for the best texture. The spice blend requires 2 tablespoons of Kashmiri red chili powder (or paprika for milder heat), 1 tablespoon of coriander powder, 2 teaspoons of cumin powder, 1 teaspoon of turmeric powder, and 1 teaspoon of garam masala powder.
You’ll also need 1 cup of plain Greek yogurt, 4 large onions thinly sliced, 6 cloves of garlic minced, 2 inches of fresh ginger grated, 4 green cardamom pods, 2 black cardamom pods, 4 whole cloves, 2 bay leaves, and 1 cinnamon stick. For cooking, gather 4 tablespoons of ghee or vegetable oil, 2 cups of warm water or beef stock, and salt to taste. Fresh cilantro leaves make an excellent garnish.
Preparing the Meat
Start by washing the lamb pieces thoroughly under cold water and patting them completely dry with paper towels. This step is crucial for achieving the right texture. In a large bowl, combine the lamb with half a cup of yogurt, half a teaspoon each of turmeric and red chili powder, and a generous pinch of salt. Mix everything well, ensuring each piece of meat is well coated with the marinade. Cover the bowl and let it rest for at least 30 minutes at room temperature, or up to 2 hours in the refrigerator for deeper flavor penetration.
Building the Flavor Base
Heat the ghee or oil in a heavy-bottomed pot or Dutch oven over medium-high heat. Add the whole spices including cardamom pods, cloves, bay leaves, and cinnamon stick. Let them sizzle for about 30 seconds until they become fragrant and release their oils. This technique, called tempering, forms the aromatic foundation of the dish.
Add the sliced onions to the pot and cook them slowly, stirring occasionally, until they turn golden brown and caramelized. This process takes about 15-20 minutes but is essential for developing the rich, sweet base that Rogan Josh is known for. The onions should be evenly colored and soft when done.
Creating the Spice Paste
Once the onions are perfectly caramelized, add the minced garlic and grated ginger to the pot. Stir continuously for 2-3 minutes until the raw smell disappears and the mixture becomes fragrant. Now add all the ground spices including the remaining red chili powder, coriander, cumin, and garam masala. Cook this spice mixture for another 2 minutes, stirring constantly to prevent burning while allowing the spices to bloom and release their full flavor.
Cooking the Meat
Add the marinated lamb pieces along with all the marinade to the pot. Increase the heat to high and cook for 8-10 minutes, stirring frequently to ensure the meat browns evenly on all sides. The meat should develop a nice crust while absorbing all the spice flavors. During this process, you’ll notice the oil beginning to separate from the mixture, which indicates that the spices are properly cooked.
The Slow Cooking Process
Whisk the remaining yogurt until smooth and gradually add it to the pot, stirring continuously to prevent curdling. Once the yogurt is fully incorporated, add the warm water or stock. The liquid should just cover the meat. Bring the mixture to a rolling boil, then immediately reduce the heat to low and cover the pot with a tight-fitting lid.
Let the Rogan Josh simmer gently for about 1 hour to 1 hour and 15 minutes, stirring occasionally and checking that it doesn’t stick to the bottom. The meat should become fork-tender and the sauce should reduce to a rich, thick consistency that coats the back of a spoon. If the sauce becomes too thick during cooking, add a little more warm water. If it’s too thin near the end, remove the lid and let it reduce further.
Final Touches and Serving
Taste the curry and adjust the seasoning with salt as needed. The finished Rogan Josh should have a beautiful deep red color, tender meat that falls apart easily, and a rich, aromatic sauce that’s neither too thick nor too thin. Remove the whole spices like bay leaves and cardamom pods if you prefer, though traditionally they’re left in the dish.
Garnish with fresh cilantro leaves and serve hot with steamed basmati rice, naan bread, or roti. The curry actually tastes even better the next day as the flavors continue to develop, making it perfect for meal preparation or entertaining guests. Store any leftovers in the refrigerator for up to 3 days or freeze for up to 3 months.
