  1. Heat the oil in a frying pan, then fry the onion until golden. Add the carrots and all but a sprinkling of thyme. Pour in the wine, 150ml water and the tomatoes, then sprinkle in the stock cubes and simmer for 10 mins. Tip in the can of lentils, including their juice, then cover and simmer for another 10 mins until the carrots still have a bit of bite and the lentils are pulpy.

  2. Meanwhile, boil the sweet potatoes for 15 mins until tender, drain well, then mash with the butter and season to taste. Pile the lentil mixture into a pie dish, spoon the mash on top, then sprinkle over the cheese and remaining thyme. The pie can now be covered and chilled for 2 days, or frozen for up to a month.

  3. Heat oven to 190C/170C fan/gas 5. Cook for 20 mins if cooking straight away, or for 40 mins from chilled, until golden and hot all the way through. Serve with broccoli.

Really good taste - first decent vegetarian shepherd's pie I've had. I reckon it could've done with a bit more potato because I found it was spread a bit thin, but that could be because of the shape of dish I have. When I first made it I found it a bit liquidy, but when I had it the second it was fine

I LOVE this recipe. Following comments I added a butternut squash and a pack of mushrooms and it is delicious. So full of flavour, and it makes so much. Easily 6 portions. Instead of adding 150ml of water I just let it simmer and added water as and when it needed it - that way you can get the consistency just right.

Makes a nice change to lamb. I use chicken stock because that is generally what I have and half normal potato half sweet potato mash as we find it a bit too sweet otherwise. Only add half the water initially as it can be too much but this too depends on the type of lentils used and whether using tinned or cooking your own from dry. I also add a couple of cloves of garlic and celery if I have some in

I do love this dish! But the thing is this recipe needs a fair bit of adjusting, as per all the comments. The carrots need a lot longer, garlic is a must - I once made it without and it tasted totally different. And season well!! I also prefer it with added butternut squash. I find that with the semi-crunchy carrots the softer squash goes really well. I don't reduce any of the other ingredients- just add half a squash.

Simple and delicious recipe. I didn't change too much just added some Chipotle and paprika to the filling. Didn't have an issue with too much fluid as used puy lentils cooked myself from dried with no extra water. Love it

I made this tonight , as other have said it does not need anymore liquid than the canned tomatoes and draiin the lentils . I added garlic and some mushrooms, served it with broccoli, rich and very warming dinner. Would cook it again.

As others I adapted this recipe a little. We are not vegetarian so I added chicken and used chicken stock. I steamed the carrots in the microwave before adding and used uncooked lentils which I also boiled in the microwave before adding. Simmered without a lid until the lentils were pulsey and the sauce was thick. Then followed the recipe for everything else. Really delicious and all the family enjoyed it. Got loads left over to freeze.

Made this tonight for my housemates and it went down a treat!! With the side of broccoli portion sizes were perfect for 4 girls. I didn't add the water from the lentils as the mixture was already looking very liquidy and I simmered the mixture for an extra 10mins until I was sure carrots were cooked and the liquid levels had reduced but otherwise barely changed a thing. Would recommend!

Absolutely delicious. Used 100ml water, quartered the carrots, added garlic & soy sauce and then put chilli flakes and paprika in the mash.

Thanks for your question. You can substitute with water if you don't want to use wine.

I made this dish yesterday for a special vegetarian guest! However, I should have made more, as the 5 other non-vegetarians really loved it too! I added Shitake mushrooms to give it more of a chunky taste. Also, I used Merlot, as the recipe was non specific about the "red wine" to use. I left it on for quite a bit longer than the recipe stated, probably 30 minutes longer (until the filling was bubbling from the edges of the dish). This may have been the reason the carrots (*issue referenced in other comments) were absolutely perfect.

Even my husband loved this (to his surprise). I didn't add liquid from the lentils and only one stock cube. I fried the onions and carrot in coconut oil first with 2 chopped cloves of garlic, then added the liquid. I used mixed herbs instead of thyme. I used butternut squash mash instead of sweet potato and topped with Parmesan cheese.... delicious will make again!

I made this dish for a buffet supper party and it was demolished in minutes - great recipe! I changed it slightly as I didn't have canned lentils. I only had dried so cooked those first according to instructions on packet. I also added some fresh garlic when frying the onions. Turned out brilliantly.

This is a great recipe (one of my personal favourites), but if you follow it to the letter, you'll probably end up with too much liquid in the lentil mixture. This is easily remedied by adding less water (I usually go for a total of 300 ml wine + water), leaving the mixture uncovered while cooking, and increasing the heat as needed to boil off excess liquid (you can always add a splash of water later if you went too far).
