To begin making Kerala Mutton Roast Recipe, wash and clean the mutton pieces well. 

In a pressure cooker, combine the mutton pieces, pepper powder, salt, turmeric powder and mix well.

Add 1 cup of water. Close the pressure cooker and place on high flame.

Once the first whistle blows, reduce the flame to low and then let it continue to be on low flame for another 30 minutes. After 30 minutes, turn off the heat and allow the pressure to release naturally. 

Transfer the mutton pieces in a bowl and keep the stock aside. The stock will be utilized later. 

In a deep pan or wok add coconut oil on medium heat. Once the oil is hot, add sliced onion and saute for about 3-4 minutes until the onions become soft and translucent.

Now add fennel seeds, ginger, garlic and curry leaves and let it cook for 2 minutes. 

To the onion mix, add red chilli powder, turmeric powder, coriander powder, garam masala powder salt and stir well. Saute for a couple of minutes until the Kerala Mutton Roast masala comes together.

Once the raw smell of the masala is gone, add the chopped tomatoes and cook until soft and mushy. This will take about 2 to 3 minutes.

At this stage add the mutton stock and the mutton pieces into this Mutton Roast masala. Let this cook on medium to high flame until the Kerala Mutton Roast becomes semi dry.

Once the Kerala Mutton Roast Recipe is done, turn off the heat, check the salt and spice levels and adjust to suit your taste.

Serve Kerala Mutton Roast along with Kerala Style Pulissery Recipe (Mor Kuzhambu) and Steamed rice for a complete meal or can be eaten along with Rotis, Ghee Roast Dosa or Kerala Style Appams.
