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 Lamb 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 is 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.

Kashmiri Red Chilli which has a vibrant red colour with less of the heat quotient.

Traditional Kashmiri lamb dish is slow-cooked with freshly ground spices in a good helping of clarified butter or ghee!

Rogan Josh is one of those rare Indian dishes made with lamb.

You can also use beef or chicken to make 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 Healthy And Easy Lamb Rogan Josh Recipe

What makes this particular 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 making it a healthy Indian Lamb Curry.

Traditionally a Rogan Josh curry base requires a considerable amount of oil/ghee to increase flavour.

Since this dish is made in a slow cooker you do not need to use as much oil which lowers the calories in a Lamb Rogan Josh, while the meat has a melt in the mouth texture.

Not only is this recipe healthy, but it is also an incredibly easy dish to make without compromising on taste.

If you do not have a slow cooker you can use an ovenproof 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.

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 other Indian curries such as chicken curry, vegetable curry or even to spice up a pie, a soup or as a marinade!!

The ingredients needed to make a freshly ground spice mix for this Lamb Rogan Josh recipe are:

  • Green Cardamon

How To Make A Child-friendly Indian Lamb Curry

You want your kids to try out more spices and flavours but the heat may not go down well?

No worries there is an easy tip to make a kid-friendly version of lamb Rogan Josh for the whole family to enjoy which is not too spicy and hot.

To make it less spicy, all you need to do is add a tablespoon or two more of yoghurt to the sauce gravy and reduce the number of whole chillies when making the spice blend for a child-friendly version of an Indian Lamb Curry.

Follow the instruction for the Lamb Rogan Josh recipe.

Then once the lamb is cooked, remove some of the lamb and gravy from the slow cooker.

Add more of the spice blend and/or chilli powder to the remaining part of the dish in the cooker and continue to cook for another 1/2 hour for a spicier hot version.

Cooking Notes To Know Before You Cook Lamb Rogan Josh

  1. Although a freshly grounded spice in best for an authentic Lamb Rogan Josh taste, you can also replace the spice mix with a shop-bought spice mix or use a tsp of Garam Masala powder, 2 teaspoons of Kashmiri chilli powder and 1 teaspoon of coriander powder in place of the spice mix.

My recommended shop-bought Rogan Josh spice mix is from The Savoury Spice Shop.

2. Slow cooking lamb in a slow cooker or a pressure cooker does not require a lot of water. Make sure you do not add too much liquid. Remember yoghurt and lamb has its own juices that will also release water and make the gravy for the lamb curry.

3. If you feel that the gravy is too thick, add a little warm water.

4. Dice the potatoes in large thick chunks, they will cook faster than the lamb. I normally add potatoes halfway through cooking the lamb (when at home)

5. Always reserve a teaspoon of the spice blend and add it in the last 15 minutes of cooking in the slow cooker for amping up the flavour of the lamb curry.

6. I recommend sealing the lamb with ginger garlic paste, and onions in a hot pan before adding it to the slow cooker. This adds a lot of flavour to the dish.
