Some people add nuts like cashews to Kadhai Paneer to make the dish creamy and rich. Cashews are soft when cooked and blend well with the gravy. They add a mild, sweet flavor that makes the curry taste better. Cashews also thicken the sauce without using cream. This makes the dish feel more special and filling. Some people grind the cashews into a paste before adding. Others put whole or chopped cashews directly into the pan. It depends on how rich they want the dish to be. Adding cashews is common in restaurants and at home for a tasty touch. You can also buy kadai paneer masala which is a simple way to improve the flavor and texture of Kadhai Paneer.
