Super tender chunks of lamb in a creamy tomato based sauce with a little kick of heat and a generous portion of spinach. This slow cooker lamb rogan josh tastes far more indulgent than it is, and it's a delicious alternative to ordering a curry.
Although the word slow in the title gives it away that it isn't a quick meal in terms of cooking time, it is a quick meal to prepare. This slow cooker lamb curry is the perfect weeknight meal.

Ingredients and Substitutions
A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Lamb - We used lamb fillet and cut it up, but you can buy ready diced lamb from the supermarket.
- Spinach - To add a green boost at the end. You could use kale instead though, or even add some frozen peas.
- Tomatoes - We used a good quality plum tomatoes as these have slightly less metallic taste than chopped tomatoes. If you use cheap tinned tomatoes, they tend to be too watery.
- Shallots - These add a slight sweet taste to the curry - a normal onion will still work fine.
- Garlic and ginger - The base of any curry. You can use the jars of lazy ready crushed garlic and ginger to save yourself some time.
- Greek yogurt - Makes the rogan josh sauce a little creamier and cools it down a bit. You could use single cream if you prefer.
- Stock - We used a vegetable stock, but a beef or chicken stock will also work. Try to use a low salt stock.
- Spice blend - We used a mix of ground coriander, turmeric, cumin, garam masala and chilli powder. You can also add cinnamon and paprika if you wish.
Variations
This is a really simple curry, so you don't want to over complicate it too much. However, you can add some different vegetables if you want to bulk it out a little, and add more nutrients. We like adding some peppers, aubergine (eggplant) and courgette (zucchini) to it, although that is far from traditional.
Instead of adding spinach, you could stir some kale into it.
For some added protein, cooked lentils or chickpeas are a good addition. If you wanted to make the whole meal in the slow cooker, then you can add a drained tin of new potatoes. It saves having to make some rice to go with it.
How to Make Slow Cooker Rogan Josh
- Step 1: Heat the butter in a pan and then add the lamb. Gently cook for a couple of minutes, until browned.
- Step 2: Put the shallots, garlic and ginger into the pan with the lamb and gently cook for 3 minutes.
- Step 3: Add the spices, stir and cook for one minute.
- Step 4: Add the stock and tomatoes and cook for 2 minutes.
- Step 5: Pour the lamb mixture into the slow cooker, put the lid on and cook on low for 8 hours or high for 4 hours. 10 minutes before it is finished, stir through the spinach and replace the lid. Before serving, stir in the Greek yogurt.
It's time that we get those slow cooker out and let them do the work for us. They cook meat like lamb perfectly, as the slow cooking time allows it to get really tender, and it takes on all the flavour of the herbs and spices that you have thrown in there too.
Serving Suggestions
Some kind of carb is a must to go alongside a slow cooker lamb curry I think. This time we went with rice as it's simple and hard to get wrong. I like to make this yellow rice with curry, which is really easy because it's just rice boiled with turmeric in the water.
It adds some extra flavour, without extra calories, and adds a pop of colour too. You could add some cumin too. We have a slightly more in depth Turmeric Rice recipe too.
You could also serve it with our Cilantro Lime Rice, Perfect Microwave Rice or Oven Cooked Rice.
Why not go double carbs and make some of our Easy Homemade Flatbread that is perfect for mopping up all that delicious rogan josh sauce from the bowl. Make a big batch and they store well in the freezer. You could make our Easy Naan Bread or Peshwari Naan too.
Dannii's Top Tips
- We have added spinach to this dish, however you could use other greens such as kale, cabbage or chard.
- Don't cut the lamb too small, as it will just fall apart and blend into the sauce.
- We used a lamb fillet and cut it into chunks, however you could save time by buying chunks of lamb from the supermarket or butcher. You could even swap the lamb for beef or chicken.
- You can make this a little more indulgent by using single cream rather than the 0% yogurt that we used.
- If you wanted to cut back on some of the meat, you could halve the lamb and then add some mushrooms and red lentils.
- Make sure to cut all the chunks of lamb to the same size (about 4cm cubes) so they cook evenly.
- You could pull the chunks of lamb when cooked, to make kind of a pulled lamb curry, however we like the tender chunks of lamb.
Frequently Asked Questions
You don't have to, but we really recommend it as it adds such a depth of flavour. It only takes a couple of minutes and it is worth it.
Basically, you want to trigger the Maillard reaction. It is a chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavour. You don't have to though, and you can just throw everything into the slow cooker and leave it if you are really short on time.
Yes, this curry freezes really well. We regularly batch cook this dish and then portion it out into takeaway type containers to put in the fridge for easy weeknight meals. You can even freeze it with some rice, or just cook that from fresh.
It will keep in the freezer for about 3 months. Alternatively you can keep this in the fridge for 2 days.
Yes, you can swap the yogurt for coconut instead, and it would make this dairy free. It adds some delicious extra flavour that you don't get from the yogurt too, but it does change the nutritional information.
Yes, if you didn't want to make your own spice mix, then you could use a couple of heaped tablespoons of really good quality curry paste. Stir it into the lamb when you are frying it.

Rookie Curry says
I made this for the first time yesterday (and also my first Indian recipe). I doubled the recipe, 8 hour cook time in a Kitchenaide slow cooker on low.
Overall, quite tasty. I did find it lacking in flavor/zip compared to local Indian restaurants. I added a tsp of cayenne pepper as I knew the chili powder wasn't going to be enough, although I only can find "mild" American chili powder here in the US. Next batch I will consider some ground red pepper to see if I can get it a bit hotter.
I'm also going to back off on the vegetable stock. Even with 1 Tbsp. of corn starch added at the beginning, I found it a bit too thin. The imperial/US measures make chopped tomatoes a bit awkward, and I probably got too much added liquid from using the closest matching canned tomato size (28 vs. ~22 oz in the recipe). Probably drain the tomatoes more and only use 1 cup vegetable stock.
My only other question is the shallots -- what does this work out to in terms of volume of diced shallots? Literally doubling the recipe would have been 12 shallots, and the shallots here are big. I used 9 and wound up with 2.5 cups of diced shallots, which seemed too much, although not a problem in the finished dish.
Dannii says
Thanks for your feedback. This won't have the same flavour as an Indian restaurant, due to not using ghee or a lot of oil. That's where all the flavour (and calories comes from usually).
Yes, US chilli powder and UK chilli powder are very different. Ours is pretty spicy, so cayenne was a good addition.
The type of canned tomatoes make a huge difference to the amount of liquid that is left too, as some canned tomatoes are quite liquidy to begin with.
Yes, that is a lot of shallots. Our shallots here in the UK are pretty small - 6 shallots would be the same as a medium sized onion.
Rookie Curry says
Do you know what chillis are used in UK chili powder? I might try a substitution, as I suspect US chilli powder is mostly a "Mexican" flavor ingredient and not meant for adding heat. The shallots might not have been that off then, two medium size onion wouldn't be far off the ~2 cups shallots I ended up using. They were large by even our shallot standards, but these days I'm taking what I find at the grocery. In a restaurant (or I'd guess traditional) recipe, does the Ghee replace the yogurt at the end or is it just added?
Gaz says
Try some fresh green chillies to ad heat maybe 4 or 5 just top and tail them.
Ghee is a clarified butter and is used for frying instead of oil or butter.
Rob says
Didn’t have a slow cooker so did 500ml of stock at 140C for 5 hours with half a shoulder of lamb. Absolutely lovely.
Dannii says
So glad you enjoyed it :)
Phil Dixie says
The first curry that I had was a Lamb Rogan Josh at Smileys in Baker Street, London about 45 years ago which I thought was brill, but this one puts it to shame. Absolutely brilliant.
