The slow-cooker is fantastic for a curry- it gives plenty of time for the flavours of the spices to develop, and for meat like beef and lamb, it ensures that you have tender, fall apart meat with not a chewy bit in sight!

I also love the slow-cooker because it’s hands off cooking- this meal just takes about 7-8 minutes to do, including chopping and frying, then once it’s in the slow-cooker you can just leave it and get on with your day!

This slow-cooker tandoori beef masala makes a lovely satisfying curry. One of my favourite ways to do a curry sauce at the moment is to bulk out the sauce with extra lentils, and in this curry I have also used sweet potato which adds to a rich, thick and tasty sauce.

My slow-cooker is about 20 years old, but still in perfect working order- there are loads of great, and cost-effective options around, but if I were to get a new one I would probably go for something like this one, which has a ‘sear and stew’ function, to save having to do any cooking on the hob first: 

I like an ‘easy’ curry- as much as I’d very happily eat one cooked by someone else that is complex, I always prefer to keep my dishes as simple as I can. This is why in this one I have used a Tandoori curry powder mix rather than mixing up my own spices- it just makes it that little bit quicker to throw together.

What other healthy curry recipes are there?

If you love healthy, Slimming World friendly curries, why not have a look at some of the others on my blog! I love a chicken tikka masala (and I have 2 versions on the blog: Skinny chicken tikka masala and slow-cooker chicken tikka masala). A beef madras, A vegan mushroom, chickpea and lentil curry,  chicken katsu curry


What equipment is helpful?

If I’m mixing up my spices, I use a mini chopper- if you don’t have one then I really recommend investing! They aren’t expensive to buy, and are so handy both for making curry pastes and other types of sauces and pestos. I have this one from Tefal, which I love:

I accompanied this curry with my sweet potato onion bhajis which are delicious, and oven-baked so they aren’t at all greasy!


Quick tips!:

Need to speed up the process of making this curry? You can use frozen pre-chopped onion, lazy garlic and ginger, and frozen (or fresh) pre-chopped sweet potato!
