An incredibly easy and flavour packed Slow Cooker Lamb Rogan Josh recipe made with only 2 tbsp of oil for a healthy low-calorie Indian Lamb Curry version.

What is Rogan Josh

It is believed that Rogan Josh originated in Persia and was introduced by the Mughals to the Kashmiri Cuisine also known as Wazwan. Wazwan in a multi-dish course prepared and offered during big Kashmiri occasions.

‘Rogan’ means red while ‘Josh’ means passion or heat.

Hence the fiery red oil layered succulent pieces of meat that is the customary Rogan Josh gravy!

The redness of the dish comes from making a paste of Kashmiri Red Chillies which has a vibrant red colour with a little less of the heat quotient slow cooked in a good helping of clarified butter or ghee!

Rogan Josh is normally made using lamb or any red meat of your choice, but Chicken Rogan josh has become equally popular with those who enjoy the aroma packed Rogan Josh sauce but not too keen on red meat.

The heat of the chillies is mellowed down with the use of yoghurt and tomato to make the gravy.

The Healthier Lamb Rogan Josh Recipe

What makes this particular recipe version of Rogan Josh special and unique is that although it uses the traditional spices to make a Rogan Josh base it cuts out on the oil and cooking time.

Traditionally a Rogan Josh curry base requires a considerable amount of oil/ghee to increase flavour, but since this dish is made in a slow cooker you do not need to use as much oil and yet not compromise on its taste.

If you do not have a slow cooker you can use an oven proof dish, or a pressure cooker or even cook it on the lowest stovetop heat to make this dish.

Home Made Rogan Josh Spice Mix

Kashmiri cuisine in one of my most favourite Indian cuisine. The reason being that they use robust strong spices which bring absolutely scintillating flavours to dishes.

It is a delicate, aromatic and rustic way of cooking which differentiates it from other popular Indian dishes that you may be used to.

It is only when I started to make Kashmiri food often, I realised that you don’t really need lots of onions or garlic to make a dish tasty. Knowing and using spices and herbs correctly is all you need to do to enhance flavours of the blandest of foods be it spinach, potatoes or Brussel sprouts!

I make this basic Rogan Josh Spice blend at home and store it to make not just Rogan Josh but a chicken curry, vegetable curry or even a spiced up pie!!
