How to Make Bengali Mushroom Kosha with Potato
Step 1: Clean the Mushrooms
Place the mushrooms in a bowl and clean away any visible dirt or compost. The recipe uses a tablespoon of flour to help loosen the dirt from the mushroom surfaces.
Gently rub the mushrooms, then rinse thoroughly with fresh water, changing the water several times until it runs clear. Drain well.
Cut each mushroom into halves. If the mushrooms are particularly large, cut them into quarters rather than thin slices.
Step 2: Cut the Potato
Peel one large potato and cut it into chunky pieces roughly similar in size to the mushroom pieces. This helps the vegetables cook evenly and gives the curry a hearty texture.
Step 3: Fry the Potatoes
Heat approximately four tablespoons of cooking oil in a kadai.
Once the oil is hot, add the potato pieces along with a little salt and turmeric powder. Fry until the potatoes develop a light golden colour.
Step 4: Fry the Onions
Add the finely chopped onions to the potatoes. Continue frying until the onions turn golden brown.
Step 5: Add Ginger-Garlic Paste
Add ginger-garlic paste and a few slit green chillies. Fry for a little longer until the raw aroma of the ginger and garlic disappears.
Step 6: Add the Ground Spices
Add turmeric powder, red chilli powder, coriander powder, cumin powder and Kashmiri red chilli powder.
Lower the heat and mix well. Cook the spices slowly, stirring regularly so that they do not burn. Properly cooking the masala is an important step in developing the rich flavour of Bengali mushroom kosha.
Step 7: Add Mushrooms and Tomato
Add the cleaned mushrooms to the pan and stir to coat them with the masala.
Next, add the chopped tomato. Mix well and cook until the tomato begins to soften and blend into the gravy.
Step 8: Prepare the Secret Roasted Spice Powder
In a separate pan, add whole cumin seeds, whole coriander seeds, cardamom, cloves, cinnamon, black peppercorns and dried red chillies.
Add a little salt and roast the spices over low to medium heat, stirring so they roast evenly without burning.
Allow the spices to cool, then grind them into a fine powder. This freshly roasted spice blend gives the curry its distinctive aroma.
Step 9: Add the Secret Masala
Sprinkle the freshly ground spice powder into the mushroom mixture.
Mix thoroughly so the mushrooms and potatoes are evenly coated. Cook for a short while to allow the spices to release their aroma.
Step 10: Add Hot Water and Simmer
Pour in approximately three medium cups of hot water. Adjust the quantity according to how much gravy you prefer, keeping enough liquid for the potatoes to cook properly.
Cover the pan and cook for approximately 5–7 minutes, or until the potatoes are tender and the gravy thickens.
Cooking time can vary depending on the size of the potato pieces and the heat level.
Step 11: Finish the Mushroom Kosha
Check the potatoes and taste the gravy. Add more salt if required and a little sugar if you prefer a balanced Bengali-style flavour.
Add one slit green chilli, approximately ¼ teaspoon of garam masala powder, a little ghee and chopped fresh coriander leaves.
Mix gently, cover and simmer for another 30 seconds. Turn off the heat and leave the curry covered for about two minutes so the flavours can settle.

Tips for Perfect Mushroom Kosha
- Clean the mushrooms thoroughly: Remove any visible dirt before cooking.
- Avoid thinly slicing the mushrooms: Halves or quarters give the dish a chunkier texture.
- Fry the potatoes first: This helps them hold their shape while simmering.
- Cook the masala on low heat: This prevents the powdered spices from burning.
- Roast the whole spices carefully: Over-roasting can make the spice powder bitter.
- Use hot water: It helps maintain the cooking temperature when you add liquid.
- Finish with ghee and garam masala: Add these near the end for a fragrant finish.
