  • 500 grams mutton, cut into pieces
  • 3 onions, finely chopped
  • 2 tomatoes, pureed
  • 3-4 green chilies, slit
  • 2 tablespoons ginger-garlic paste
  • 1 tablespoon turmeric powder
  • 2 tablespoons red chili powder
  • 1 tablespoon cumin powder
  • 1 tablespoon coriander powder
  • 1 teaspoon garam masala powder
  • 2-3 bay leaves
  • 4-5 cloves
  • 4-5 green cardamom pods
  • 1-inch cinnamon stick
  • 2-3 tablespoons mustard oil
  • Salt to taste
  • Fresh coriander leaves for garnish


1. Marinate the Mutton:
  • In a large bowl, combine the mutton pieces with ginger-garlic paste, turmeric powder, red chili powder, cumin powder, coriander powder, and salt.
  • Mix well to ensure that the mutton pieces are evenly coated with the spices.
  • Cover the bowl and let the mutton marinate for at least 1-2 hours, or preferably overnight in the refrigerator, to allow the flavors to meld.
2. Prepare the Masala Paste:
  • Heat a pan over medium heat and add 1 tablespoon of mustard oil.
  • Add the chopped onions to the pan and sauté until they turn golden brown and caramelized.
  • Remove the onions from the pan and allow them to cool slightly.
  • Once cooled, transfer the onions to a blender along with the tomatoes, green chilies, and a splash of water.
  • Blend until you get a smooth masala paste. Set aside for later use.
3. Cook the Mutton:
  • Heat the remaining mustard oil in a heavy-bottomed pan or pressure cooker over medium heat.
  • Add the bay leaves, cloves, cardamom pods, and cinnamon stick to the pan and sauté for a few seconds until fragrant.
  • Add the marinated mutton pieces to the pan and cook until they are browned on all sides, stirring occasionally.
  • Once the mutton is browned, add the prepared masala paste to the pan and mix well to combine.
  • Cook the masala and mutton together for a few minutes until the oil starts to separate from the masala and the raw smell disappears.
  • If using a pressure cooker, add 1-2 cups of water at this stage, depending on the desired consistency of the curry. If using a regular pan, add enough water to cover the mutton pieces.
  • Close the pressure cooker lid and cook the mutton on medium heat for about 4-5 whistles, or until the mutton is tender and cooked through. If using a regular pan, cover with a lid and simmer the curry until the mutton is tender, stirring occasionally.
4. Finish and Serve:
  • Once the mutton is cooked, open the pressure cooker lid and check for seasoning. Adjust salt and spice levels if necessary.
  • Sprinkle garam masala powder over the curry and give it a final stir.
  • Garnish with fresh coriander leaves and remove from heat.
  • Serve hot with steamed rice, pulao, or paratha, and enjoy the delicious flavors of this authentic Bengali delicacy.


  • For best results, use freshly ground whole spices for a more intense flavor.
  • Slow-cooking the mutton curry enhances the flavors and tenderizes the meat, so be patient and allow it to cook on low heat.
  • Adjust the spiciness of the curry according to your taste preferences by adding more or fewer green chilies and red chili powder.
  • Leftover Kosha Mangsho tastes even better the next day as the flavors continue to develop, so feel free to make a large batch and enjoy it over multiple meals.
