Now heat 1 tablespoon oil in the same pan. Add 1 small to medium tej patta and ½ teaspoon shahi jeera (caraway seeds).
Fry till the shahi jeera splutters on low heat. If you do not have shahi jeera, then you can use jeera (cumin seeds) or else skip shahi jeera.
Now add the chopped mushrooms. Stir and mix them well.

Now add ¼ teaspoon kashmiri red chilli powder and ¼ teaspoon black pepper powder. mix very well.
Now add the ground onion-tomato-cashew paste and mix very well.
Saute stirring non-stop for 4 to 5 minutes. Then add 1 cup water and mix again very well.
Season with salt as per taste and mix again. On a low heat let the gravy come to a boil.
Then add ¼ teaspoon garam masala powder and ¼ teaspoon kasuri methi (crushed). mix again well.
Now add 200 grams paneer chopped in cubes or squares.
Then add ¼ cup grated or crumbled paneer. You can use 3 to 4 cubes from the 200 grams paneer and crumble them and add.
Mix very well and simmer for a few seconds.
Switch off heat and add 1 tablespoon chopped coriander leaves.
Mix well and serve mushroom paneer with tandoori roti, phulka, naan, butter naan, pudina paratha, kerala parotta and even pooris.
