Mutton Kasa
A classic Bengali delicacy where tender mutton pieces are slow-cooked in a rich, spicy gravy. The 'kasa' or bhuna technique creates an intense flavor that's perfect with rice or luchi.
For 4 servings
Marinate the Mutton
- In a large bowl, combine the mutton pieces, whisked curd, 1 tbsp ginger paste, 1 tbsp garlic paste, turmeric powder, 1 tsp red chili powder, and 1 tsp salt.
- Mix thoroughly with your hands, ensuring each piece of mutton is well-coated.
- Cover the bowl and let it marinate for at least 30 minutes at room temperature, or up to 4 hours in the refrigerator for best results.
Fry Potatoes and Sauté Aromatics
- Heat mustard oil in a pressure cooker or a heavy-bottomed pan over medium-high heat until it is lightly smoking. This mellows its pungent flavor.
- Carefully add the potato halves and fry for 4-5 minutes, turning occasionally, until they are golden brown on all sides. Remove with a slotted spoon and set aside.
- In the same oil, add the bay leaves, cinnamon stick, green cardamoms, and cloves. Sauté for about 30 seconds until they become fragrant.
- Add the sliced onions and a pinch of sugar. Fry for 12-15 minutes, stirring frequently, until the onions are deep golden brown and caramelized.
Prepare the Masala Base
- Add the remaining 1 tbsp of ginger paste and 1 tbsp of garlic paste to the pan. Sauté for 1-2 minutes until the raw aroma disappears.
- Stir in the tomato puree, remaining 1 tsp red chili powder, cumin powder, and coriander powder.
- Cook this masala mixture for 6-8 minutes, stirring occasionally, until the tomatoes are well-cooked and you see oil separating from the sides of the masala.
The 'Kasa' (Slow-Frying) Process
- Add the marinated mutton to the cooker. Increase the heat to medium-high and mix well to coat the mutton with the masala.
- This is the crucial 'kasa' step. Cook the mutton for 20-25 minutes, stirring every few minutes to prevent it from sticking.
- The mutton will initially release a lot of water. Continue to cook, stirring, until all the water has evaporated, the masala darkens in color, and oil begins to ooze out from the mixture. The masala should be thick and cling to the mutton pieces.
Pressure Cook to Tenderness
- Return the fried potatoes to the cooker. Add the slit green chilies and the remaining 0.5 tsp of salt.
- Pour in 2 cups of hot water and stir everything to combine. The water should just about cover the mutton.
- Secure the lid of the pressure cooker. Cook on high heat until the first whistle. Then, reduce the heat to medium-low and cook for 5-6 more whistles (approximately 20-25 minutes), or until the mutton is fork-tender.
- If not using a pressure cooker, cover the pan with a tight lid, reduce heat to low, and simmer for 75-90 minutes, until the mutton is fully cooked.
Finish and Rest
- Turn off the heat and let the pressure release naturally from the cooker. This can take 10-15 minutes.
- Open the lid. Stir in the garam masala and ghee. Check for seasoning and add more salt if needed.
- If the gravy is too thin for your liking, simmer uncovered for 3-5 minutes to thicken it.
- Let the Mutton Kasa rest for at least 15 minutes before serving. This allows the flavors to meld and deepen. Serve hot with steamed rice, luchi, or parathas.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1The 'kasa' or slow-frying step is the soul of this dish. Do not rush this process; it's essential for developing the deep, rich flavor.
- 2Using mustard oil is key for the authentic Bengali taste. Always heat it until it's lightly smoking to mellow its pungent flavor before adding other ingredients.
- 3Always use hot water when making the gravy. Adding cold water can shock the meat, making it tough and slowing down the cooking process.
- 4Frying the potatoes separately ensures they hold their shape and develop a delicious crust, preventing them from turning mushy in the gravy.
- 5For exceptionally tender mutton, marinate it overnight in the refrigerator.
- 6Letting the dish rest after cooking is crucial. It allows the mutton to absorb the flavors of the gravy, making the dish even more delicious.

Cooking Method
For a richer, deeper flavor, you can slow-cook the mutton in a heavy-bottomed pot (like a Dutch oven) for 1.5 to 2 hours on low heat instead of using a pressure cooker. Ensure the pot is tightly covered.
IngredientIngredient
For a slightly different flavor profile, you can substitute mutton with goat meat (chevon). The cooking time might need a slight adjustment.
Spice LevelSpice Level
To make it less spicy, reduce the red chili powder to 1 teaspoon and use whole green chilies instead of slitting them. For a spicier version, add a teaspoon of black pepper powder along with the other powdered spices.
