A Lamb Rogan Josh is a classic Indian takeaway order, and now you can cook it in the slow cooker and it's just 450 calories. This Slow Cooker Lamb Curry has quickly become a firm favourite in our house, and even has a portion of veggies in it. Cooked low and slow, it takes very little effort and is bursting with flavour.
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.
- 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.

How to make slow cooker rogan josh - Step by step
One: Heat the butter in a pan and then add the lamb. Gently cook for a couple of minutes, until browned.

Three: Add the spices, stir and cook for one minute.
Four: Add the stock and tomatoes and cook for 2 minutes.
Five: 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.
Six: Serve with rice.
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.
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.
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.
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.
As this is a homemade curry, it is a healthier alternative to ordering a takeaway. You can control exactly what goes in it and make sure it is lower in salt. It has a generous portion of spinach and lamb is a great source of iron.
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.
