Leek and potato soup recipe: a chunky and simple one pot meal


Last Updated on January 25, 2021

I admit this leek and potato soup recipe is so simple and self-explaining that I asked myself before, if I should really publish the instructions. After cooking the quick easy soup and eating 2 bowls of it combined with my homemade whole wheat bread, I came to the conclusion that I should share this delicious recipe with the world.

If it can inspire only one person to cook it instead of opening a can of convenience soup, it’ll make my day. I’m dedicating this recipe especially to all those people, who are still claiming that clean eating for them is too complex and time-consuming. With this chunky potato soup – which can be ready in under 30 minutes – the opposite is true.

leek and potato soup recipeThis simple leek and potato soup consists just of 3 main ingredients, you can guess them if you look at the photos: leek, potatoes and carrots, with leek playing the dominating role. Leek is together with onion and garlic part of the allium family, hence its aroma is similar to a mixture of onion and garlic, but milder in taste.

By the way,  you can get leek all year round. The summer leek is slimmer than the winter vegetable and in comparison it tastes a little milder and tender. I’ll also add the top health benefits of leek at the end of this blog post. Hint: It is a great veggie to promote digestion and thus perfect for weight management.

That’s what you’ll need

leek potato soup ingredients

Ingredient notes

  • leek: Gourmet cooks recommend to use only the light and light green parts of leek for cooking. Not seldom sand and dirt collect between the leaves. But I’m using also some darker leaves from the inner part as long as they are clean. They give this plant-based soup a more intense taste and I love also the color contrast. It is best to cut the shaft lengthwise until right before the end of the shaft and rinse it thoroughly.
  • vegetable broth: if you can’t get additive-free ant salt-reduced veggie broth, a great approach is to use homemade vegetable stock concentrate.
  • nutmeg: Besides of optional pepper and salt seasoning, nutmeg is the only season and I feel it is a great addition to the soup

The top 2 anti-cancer vegetable

And if this is not enough to convince you, maybe the research from Dr. Michael Greger does. When it comes to anti-cancer properties, some vegetables are more beneficial than others. In fact he could find out that leek is right after garlic the number 2 top vegetable most adept at blocking human cancer cell growth in a petri dish.(1)

Overall he highlighted 2 super food classes: allium vegetables and cruciferous vegetables. Let’s pretend you want to consume vegetables with the highest anti-cancer properties. In that case allium vegetables and cruciferous vegetables would be on top of the list.
