Take the Tomatoes and Onions, wash and chop them. If you want you can use chopped tomatoes. I prefer tomato puree only.
Wash the potatoes and peel them. Cut into small cubed pieces. Keep it aside.
Heat Oil in a pressure cooker or kadai or pan over medium heat. I am using pressure cooker here.
Add Cumin Seeds and allow it to sizzle.
Add Slit Green Chilli and Chopped Onions. Fry them till the onions are slightly golden in colour.
Next add the Ginger Garlic Paste and saute it till the raw smell of the ginger and garlic goes off.
Now add the Tomato Puree and Salt. Cook till oil starts coming out from the edges of the cooker or kadai.
Add Turmeric Powder, Red Chilli Powder, Coriander Powder, Garam Masala and Asafoetida. Fry them for few minutes till the aroma of the spices starts coming out.
Now add the Chopped Potatoes and Peas. Mix them so that they are coated with the spices.
Cook for 2 minutes so that the spices are properly mixed with the potatoes and peas.
Add Water to the cooked ingredients and mix well. The quantity of water should be as per your requirement of the thickness of the gravy
Cover the lid of the pressure cooker. Cook over medium heat for 2 whistles only.
Switch off the stove and allow the pressure of the gas to come down by itself.
Open the lid and add Kasuri Methi. Mix it. Mash the potatoes slightly to thicken the gravy. Even after mashing the gravy is thin, simmer it for few minutes till it thickens.
Lastly add Chopped Coriander Leaves and mix well. Aloo Matar Gravy is ready to be served.
Serve Aloo Matar Gravy by garnishing with Coriander Leaves with your favourite Naan, Roti or any Rice Recipes.
