Nice and cheap for a meat free night. That said I rarely have vegetable stock in so generally use chicken stock. I do add loads of celery too because we love it in most stews and use swede and turnip instead of potato. Don't generally bother with the Naan. Spice levels can be changed to taste. A lovely heart warming pot of goodness to come home to after a long walk in the woods with the dog

And now for another exciting episode of "Spicy Root and Lentil Casserole!"....A couple of things. First, I have a 6 liter multi-cooker with a non-stick surface, so oil was not necessary. (The multi-cooker part comes later). Like several others, I substituted turnip/sweet potato for the parsnips. In my case one of each. Also,I had to use brown lentils as the red ones are apparently out of season where I live. Everything was going according to plan until it came time to chop up the sweet potato and the steak knife which I had used successfuly to chop up everything else; simply was not up to task. I did what I usually do with problem root vegetables: Brought out the grater! Now that the sweet potato was grated, I couldn't very well saute it with the rest of the vegetables, so I opted to add it in with the water. After I had added the lentils and it was time to simmer I decided that there would be no better way to let the root vegetables absorb the flavors, than to slow cook! I switched the multi-cooker to "slow cook" and set it on "Low" for about 5 1/2 hours (surprisingly, I used the same amount of water as the recipe called for and everything turned out just fine. It was hearty and delicious, and I couldn't even finish the second serving! The cilantro really "makes the dish". While I liked it as a stew, the person who said it would make a good cream soup was right, and I too will be putting it in the blender. As for the sweet potato, the flavor was completely "absorbed into the dish". Great recipe!

Hi. I've only ever seen dried red lentils?

Very tasty, will prepare it again.

Delicious. Just a tad carb-heavy protein-light for me as a confirmed carnivore but the flavours are top-notch. Four stars.

Oh how we love this in my house. It's usually made in the same week as the Pistou Soup (also on GF site) as there are always left over veg, half a celeriac, those few too many turnips, etc. I use the Patak's Balti paste as it suits our spice levels. But add some Nigella and cumin seeds when the onion and garlic are soft. Generally use 250g of lentils and therefore a bit more stock never measure that! End up freezing at least 2 portions after feeding two very hungry men and myself. All served with some flat bread.

Love this dish, made it a few times now and it's a massive hit in our household! Not a fan of curry powder so as per some of the other comments I substituted it for tumeric, cumin and some garam masala. I also reduced the amount of potatoes a bit and added some turnip. Really tasty!

This so much tastier than I thought it was going to be! I used a mix of sweet potatoes and white potatoes and a tikka masala curry past from Waitrose. I served it with cauliflower rice to keep it super healthy. I would say this is a vegetable curry not a casserole but whatever you call it I will be making it again. Yum Yum
