Shahi paneer is a rich gravy made with paneer in a tomato based gravy with cream, butter to make it rich and delicious! I usually make this way(stove top method though),but saw this simple recipe in a cook book and tried it for a change. It was a welcome change and with simpler ingredients. Using butter or oil is purely your choice, according to the taste(richness) you want.
Garnish with the chopped coriander leaves and serve as accompaniment for roti or mild pulavs.
