  • 250ml natural yogurt, plus extra to serve
  • coriander or parsley, to finish


  1. Peel and halve the onions through the root, then slice thinly lengthways. Heat 2 tbsp of the oil in a large pan, add half the onions and fry until just starting to colour. Add the mustard and cumin seeds and fry until nicely browned.

I make this once a week as its so good. I add some dried chilli flakes too as I like it spicy. I don't bother with the natural yogurt though. Highly recommend this delicious soup

This soup needed to be dairy free so I left out the yoghurt and it was still delicious. I used extra parsnips instead of potatoes and cumin powder instead of seeds but all the flavours were lovely.

Made this last night and used sweet potato instead of regular and extra stock (my sweet potatoes were perhaps a bit bigger than needed!). Also went with curry powder and cumin powder as alternatives and missed out the yoghurt but it turned out brilliantly! A great winter warmer!

Left out the yogurt and used cumin powder rather than seeds and Thai green curry paste. Tastes amazing! Best soup I've tried.

Delicious made with celeriac. Will be making it with parsnips in the very near future

Very tasty and I loved the crispy onions although I didn't think mine were going to go crispy for a while! Just one quick hint to any inexperienced veggies out there - when you buy the natural yoghurt, be careful to check the ingredients. A few of them (particularly low-fat ones) contain gelatine. So just make sure you get an actual vegetarian natural yoghurt.

I make a different soup each week during the winter & this is one the nicest I've come across, used a tablespoon of curry powder instead of curry paste and 1/2 vegtable 1/2homemade chicken stock that I had in the fridge. So nice I won't bother with the extra fried onions unless serving to guests. Good enough for a supper or lunch for friends.
