Chicken kosha recipe | Bengali kosha murgir mangsho recipe

Chicken kosha recipe or Bengali kosha murgir mangsho recipe with step-by-step pictures. Chicken kosha is a bengali style spicy chicken curry made with chicken slow cooked in a few simple spices. This chicken kosha recipe is also known as kosha murgir mangsho in Bengali. As in bengali language, kosha means roast/bhuna and murgir mangsho denotes chicken meat. Mainly aloo(potatoes) are not added to chicken kosha(especially made in bengali biye barir menu or in Bengali restaurant style recipe). Though I cook it with aloo.

About Chicken kosha recipe

Chicken kosha is one of the most delectable chicken preparation of our Bengali cuisine. This is common chicken preparation in the bengali marriage ceremony (biye bari) to the birthday celebration.

For making chicken kosha, chicken is first well marinated with curd or lemon juice. Then cooked in a gravy consisting of fried onion, tomato, and green chillies paste. Followed by ginger-garlic paste, red chili powder, cumin, coriander, and turmeric powder. Seasoning with salt & sugar.

Story Behind Murgir mangsho in Bengali Kitchen

In the olden days especially before the partition of Bengal (into West Bengal & Bangladesh), chicken(murgir mangsho) was not allowed in Bengali kitchens. Not even chicken eggs or murgir dim. So there was no chance of making any murgir mangsho recipe at home neither kosha nor any other bengali chicken curry. Then mangsho means only mutton or khasir mangsho would prepare at bengali households.

But after the partition, murgir mangsho slowly got entry to Bengali kitchen with the help of modern Bengali society. Since then, murgir mangsho is also one more option to bengalis for making kosha or light curry. Today this bengali chicken kosha has a huge fan base across the world.

Healthy reason

This chicken curry is common preparation for most Bengali households. As chicken is easy to digest and good for health. And if I’m not wrong, seeing my kid and the kids around me, I guess kids love to eat chicken more than mutton. Though My husband and I choose to eat mutton, but I’ve to prepare this chicken kasha often for my kid. For him which is in high demand at my home.

Importance of garam masala in this kosha chicken curry recipe

In any Bengali kosha recipe whether with chicken or mutton, garam masala is a must used ingredient. And powdered garam masala is easy to use more than whole garam masalas. Though whole garam masala has intense long lasting smell than powdered garam masala. So today, I used whole garam masala in my way which made this bengali chicken curry more delicious and flavourful.

My unique tricks 

  • My trick – I first use bay leaves, green cardamom, cinnamon, cloves, and black peppercorn (which means whole garam masalas) for tempering in oil.
  • Then fry the sliced onion in the same oil by adding a little sugar (to get the onion easily caramelized).
  • Lastly, fry chopped tomato in the same oil until the ingredients get nice golden brown color.
  • And later blend it with green chilies and little water to get a smooth paste of it.
  • And later I used this masala paste for making the gravy of this chicken curry.

This above-mentioned masala paste is the base of my chicken kasha recipe. So here, all the little-fried garam masalas will spread their flavor all over this chicken curry and make you feel that amazing blast in your mouth with every bite. Caramelized onion and sauteed tomato will give it a rich color and the pungency of green chili will enhance its taste more.

Many more tricks I have applied to in this recipe, so to know all the tricks please stay with me till the end.
