  1. Heat the oil in a large pan, then fry the onions for 6 mins until starting to turn golden. Add the garlic, carrots and thyme, and cook for 4 mins more. Stir in the mince, breaking it up with the spoon. When it has turned brown, add the lentils and swede with the flour. Cook for 1-2 mins, then gradually add the stock and red wine. Cover and simmer for 35-40 mins.

  2. Meanwhile, boil all the potatoes for 15-20 mins until tender, then drain and mash with the yogurt, nutmeg and black pepper. Spoon the meat mixture into a 2-litre ovenproof dish, spread or pipe the potato mixture on top, then grill until the topping starts to brown. (If making ahead, reheat in the oven at 180C/160C fan/gas 4 for 45 mins.) Serve with green veg, such as peas and broccoli.

Delicious, but a lot of work. Far too much liquid, but by boiling for the required time with the lid off the liquid reduced well. I soaked the lentils overnight. Should I have put them in dry?

This was a waste of time. Like previous comments, I had way too much liquid and this did not cook down even after giving it an extra 20 minutes. Why haven't the mods on this site alerted the author of the recipe to make an adjustment to the ingredients? To be fair, excess liquid or not, it was bland with a capital B. I have prepared other cottage pies (Beef) as well as Shepherd's pies (lamb) that have used sweet potato and they were all superior in every way to this very average offering. Despite making enough for 4 (not 6 as stated) we only ate about two portions, the rest is now inside the dog.

What an anti-climax! I echo the comments below that its a long recipe to cook and the output isn't worthy of the input. Its pretty plain in taste. Could use more flavour. Won't be cooking this one again....

If you use beef it is technically cottage pie!

Followed the recipe and still had a lot of liquid left in the pan. If you have time to make this there are better things you can cook. It was OK but as it's all done on the hob you have to stay near it you can't just put it in the oven and come back later.

Absolutely delicious! Made a huge batch for the freezer, I really think it's flavour improves over time. Will definitely be on my menu for a while.

After the long preparation it took me to make i was slightly disappointed! Don't get me wrong its nice enough but it all just tastes a bit too sweet.. you're mouth just craves the usual savory mash potatoes!!! Although when you're trying to be healthy i guess there has to be a compromise!!

Whoops! Commented on the wrong recipe - thought this was the veggie one. As you were.

This is delicious! Even the non-veggies in the household asked for seconds.

I really like this recipe, made it several times and always make a pie to freeze. Clever use of veg and lentils to bulk up the filling and I have used different ratios of sweet potato to white potato for topping depending on what I have in. It's a guilt free comfort food!

I used a packet of dried lentils. The recipe doesn't mention cooking them beforehand as on the packet, although I thought it a good idea just to be on the safe side. Delia would have made this clear!
