Potato leek soup

There is something exceptionally satisfying about sitting down with a deep bowl of creamy soup and a piece of crusty bread. Cooler months always have me excited at the possibility of having soup multiple times a week. This creamy, very easy potato leek soup is one I make often. It’s creamy, gentle flavors are perfect for a cozy weeknight dinner. If you want to amp up the flavors, feel free to add more mustard and even ingredients like smoked paprika, chilli flakes and mature cheddar cheese which is a perfect match to cream and potatoes.

How to make potato leek soup

Slice leeks in half lengthwise and rinse well to ensure all the dirt has been removed. Open the leaves with your fingers as you rinse under the tap to get it all out otherwise the dirt will leave your soup gritty. Finely slice the leeks then soften in melted butter in a large pot or saucepan. Add the garlic, thyme and bay leaf and fry for another 30 seconds. Add the peeled and diced potatoes. Allow the potatoes to cook for a few minutes then pour in the chicken stock. Reduce the heat and allow the soup to simmer until the potatoes are completely soft. Remove the herbs and blend with an immersion blender until smooth. Pour in the cream and season to taste with mustard, salt and pepper. Allow to simmer for another 5 minutes before serving with crusty bread.

  1. Looking forward to making this! What type of potato do you suggest? And to health it up a bit, I’m thinking to substitute the heavy cream with combo of coconut milk and pureed roasted cauliflower…..your thoughts?

  2. So sad, just finished making my Leek and Potato soup this morning – youor recipe sounds great – wish I’d seen it earlier! Will try it next time. Barry

  3. What a lovely twist to a traditional recipe! I’ve been looking for an idea to up the ‘zing’ factor in this soup, and I think the mustard must be a delicious addition! I wonder what it would be like with some hot English mustard? Or German mustard… I think that would go down a treat!
