Instructions
 

  • Heat the coconut oil in a saucepan. Add the finely chopped onion, crushed garlic, cumin, coriander, fenugreek seeds, turmeric, ginger and curry powder. Fry gently until soft to release aromas.
  • Peel the sweet potatoes and cut in 1cm dice [0.4 inches].
  • Cut the trimmed leeks in 1/2cm slices [0.2 inches]. Wash to remove dirt. Drain.
  • Add the sweet potatoes, leeks, lentils and can tomatoes to the onion mixture.
  • Top with the vegetable stock. Bring to a boil then lower to a medium heat and covered for 20-30 mins until the vegetables and lentils are soft. They should still have a bite.
  • When the casserole is cooked, add lemon juice and season to taste.
  • Serve with some warm pitta bread and fresh coriander leaves sprinkled on top.

    Really tasty dish – I made this using half the ingredients and it was more than enough for three of us. Missed out the fenugreek seeds as I had none but it had a lovely flavour nonetheless. Will definitely make it again. Thank you for the recipe!

      Hi Rachel. Please use raw lentils as they will cook in the stock with the rest of the vegetables. Annabelle

    I have made the recipe 3 times now (so far)

    and it has become one of my favourite lentil dishes.

    Amazing flavour.

    I only had a problem finding these specific lentils, so I used brown ones instead.

    What type of lentils are they exactly?.

    Thanks for this great recipe

      Thanks Angie. So glad you like the recipe. Puy lentils are small green lentils (grown in the Puy region in central France). They tend to hold their shape better and need longer time to cook than other lentils. They are grown in North America too but I am not sure they can be sold under the same name (as it is a protected name) so you might find them under “French green lentils” instead. You can use substitute them as you have. Here is a link that shows what they are https://www.amazon.ca/Whole-Foods-Organic-Speckled-Lentils/dp/B0050BAALI . Hope this helps. Annabelle

      Alisa, I am very glad you liked this recipe. Thank you so much for your feedback. Yes, you can freeze the leftovers. They will also keep in the fridge in an airtight container for 3 days. Annabelle x

    This is a lovely recipe. I divided it into two, freezing half . I’ve made others with similar ingredients but I think this is the best!

    Delicious. Didn’t have coriander, fenugreek seeds or ginger so added thyme and bay leaves. Great flavor

    I used olive oil and a red onion since that’s what I had. No fenugreek seeds as I didn’t have any. But I was impressed really nice.
