What is Kosha Murgir Mangsho?

Kosha Murgir Mangsho is a pure Bengali delicacy and the name of the recipe itself explains the dish. The word kosha comes from the Bengali word koshano. Koshano is a slow cooking technique using a minimal amount of water and murgir mangsho means chicken.

Whenever I talk about chicken kosha, it always makes me feel nostalgic. The tempting Bengali chicken curry makes me feel lucky to be a Bengali. During our childhood days, any holiday or Sunday would mean chicken or mutton for lunch. Most of the time, either it is mutton kosha and murgir jhol or kochi pathar jhol. All of them are so comforting and delectable dishes and my all-time favourite as well. Nowadays, people have become more health conscious and are trying to avoid red meat. So the demand for chicken curry has increased a lot. Most people prefer chicken for a regular feast and mutton on special occasions.

I still remember how my dad used to bring fresh-cut chicken from the market on Sundays and went to the terrace to clean it. After that, my mom used to start the preparation for kosha murgir mangsho and used to slow cook it in the kadai for a handsome amount of time. She never uses a pressure cooker for the recipe. The whole house used to smell divine right from the morning. We used to impatiently wait for lunch and get hungry earlier than the normal lunch time. I know many of you have the same childhood story as me.

Kosha chicken aka kosha murgir mangsho is very simple and easy to make. It requires very limited ingredients to prepare the dish and all the ingredients are easily available in any Indian kitchen pantry. The difficulty level of cooking this recipe is low and it could be a perfect dish for beginners or novices. Only if you compare it to mutton kosha, kosha chicken recipe gets cooked much more quickly. However, we need to stop cooking at the correct point of time or else the chicken will get overcooked.

Ingredients for Kosha Chicken

Chicken: The primary ingredient of the recipe. I have used bone-in medium-size chicken pieces for the recipe.

Yogurt: It is one of the essential components to marinate the chicken. It helps the chicken pieces to get tender and gives a creamy texture to the gravy.

Potato: The addition of potato chunks are the specialities of the Bengali chicken curry.

Onion, Ginger-Garlic & Tomato: Like any other chicken recipe, the addition of onion, garlic, ginger and tomato is compulsory to get a rich, flavoured and delicious curry.

Whole spices: Add whole spices like bay leaf, dry red chillies, cloves, cinnamon stick, green cardamom and cumin seeds into the oil for tempering. These spices induce a nice aroma into the oil. So, try to take advantage of all of these whole spices.

Ground spices: Other than whole spices, I have used ground spices – turmeric powder, red chilli powder, cumin powder, coriander powder, and Bengali garam masala powder for the recipe. All the spices help to develop a nice flavour and taste in the dish.

Sugar & Salt: For the basic taste of the dish.

Mustard oil: Always use mustard oil to cook the recipe like any other traditional Bengali food. It enhances the taste and flavour of the chicken kosha.

Ghee: Ghee is added at the final stage of cooking. It enhances the taste and flavour of the dish.

Water: It is added to adjust the consistency of the gravy.
