This recipe is a delicious slow cooker lamb Rogan josh that’s packed with flavor and has a nice amount of heat to it.

Slow Cooker Lamb Rogan Josh

This dish has a homemade curry paste made from a great selection of spices such as cardamom, cumin, cloves, turmeric and much more.

As with any curry it’s best served with some nice white rice and with some papadums or naan on the side. If you’re a bit sick of rice, then you can try something else like cauliflower rice, potato mash or even just enjoy the curry without any extras.

The leftovers will reheat nicely so make sure you keep them. Just store them in the fridge and heat in the microwave or over the stove when needed. It should last a few days before needing to be discarded. You can also freeze the curry making it perfect if you’re looking to cook a significant amount. Perfect if you love having some frozen home-cooked meals ready to reheat.

Lamb Rogan Josh

As with most curries, I make I use a homemade curry paste, but for some, this may be too much work, especially if time is limited. If this is the case with you, then you can swap out all the spices for a store bought curry sauce such as the Pataks rogan josh.

Cooking Tips

  • You can bulk out this slow cooker lamb rogan josh recipe by adding some cubed potatoes, carrots or even some lentils. It’s up to you, but keep in mind it might change the overall texture and taste of the curry.
  • Mixing the yogurt straight into the hot curry can cause the yogurt to split and not combine correctly. Heating the yogurt will help reduce the chance of it splitting.
  • You’re able to skip the browning of the meat, the cooking of the curry paste and just throw everything into the slow cooker. However, you may find the curry will not turn out nearly as good and be missing that extra boost in flavor.
