Homemade Slow Cooker Lamb Rogan Josh

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.

Recipe 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.

    The directions reference curry paste but it is not listed in the ingredients

    1. Gus on

      The curry paste is the spices, tomato paste, onion, etc. you fry in the pan.

  2. Celia on

    This looks great – thanks Gus, just a quick question, if I chose to use a ready made paste – do you have a guide on what quantity?


    1. Gus on

      Hi Celia,

      Sorry, no guide as of yet, I’ll look into doing something soon. In the meantime I would probably use 3-5 Tbsp. of a ready made paste. Leave everything out except the lamb, onion, tomato paste, and crushed tomatoes. (Maybe keep the garlic and ginger if you love those)

    Hi Gus,
    The cooking tips mention “Mixing the yogurt straight into the hot curry can cause the yogurt to split and not combine correctly”, but I can’t see a step for mixing in yogurt in the recipe? Do you mix the yogurt into the curry at the end of cooking time or do you just dollop the yogurt on top to serve?

    1. Gus on

      Hi Philippa,

      It’s up to you. Mine split when I added it to the hot curry, so I am a bit cautious about adding it as a step. If you’re worried it will split, then it’s still great with dolloped on top. Warming the yogurt beforehand will also help prevent it splitting it.

    Hi, I would leave out the cloves next time as. They overwhelmed the flavour, but otherwise good

    Hi all. Tried this recipe today with some modifications:

    – 50/50 steak pork mix (as no fresh lamb available)
    – added the yogurt to all the spices, tomato paste with 2 tbsp oil at the beginning to make the paste, then added this paste to the pan with the meat onion and garlic. Then all together in the slow cooker with a tin of pureed tomatoes. The yogurt did not separate. I used natural SET yogurt.
    – 150ml beef stock
    – 1 tsp brown sugar
    – 75gr grated almonds (brown colour) for thickening.

    All this went very well in the 3.5l pot at about 3/4 full. Perfect!

    Naan bread and a dip made of set yogurt, pressed garlic, salt, pepper and dill. Yummy!

    This dish was delicious. I took the spices and put in a zip-lock bag. I added the lamb and coated it with the spice: I had already sautéed the onion and garlic, I then added the lamb to the pan for searing: I need to add I used 2 onions and 6 cloves of garlic. When I seared the lamb the kitchen smelled amazing. After all was browned it went into the crock-pot. Cooked for 7 hours: Took sauce from meat mixed in with cold yogurt. Then folded into meat mix, plus added 2 tsp of salt and pepper: let it cook on low until lo else was ready. The lamb was so tender and flavorful. Will cook again!

    I gave this recipe 5 / 5
