Vegan Creamy Leek and Potato Soup – Quick and Simple

This vegan creamy leek and potato soup doesn’t need any time, hassle or complicated methods to make.

Because healthy food doesn’t need to be complicated.

Sometimes the most flavour comes from allowing the flavour of one ingredient to shine through, without making a carnival of other flavours to mask it.

Other soups which take their flavour from their main ingredient like this are:

So, what’s the secret to getting delicious leek and potato soup instead of bland?

Well the main thing is to have plenty of salt in the cooking phase. It’s no good just adding it at the end (sorry for anyone who’s on low salt, but this one really needs it).

Second tip is to dry-fry the onion and green leeks before putting them in the pan of water. Of course you can make this soup as a one-pan affair.

But I think there’s a slight edge to the flavour when you use two pans.

Other than that, use enough leeks, with the greens left on, and enough cashews for the creaminess.

You’ll find a lot of people claim that you shouldn’t eat the green part of the leeks because it’s fibrous. I always include the greens and I think it’s a complete waste not to.

Plus they add the lovely green colour.

Just cut out and remove any tips and the outer couple of leaves, or any which seem particularly tough and you’re good to go.
