On chilly evenings, nothing beats a classic potato and leek soup. I love adding crispy bacon and using the whole leek. The tender parts simmer into the soup while the green tops are fried until golden for a crunchy garnish.

This potato and leek soup is one of my favourites because it feels both comforting and clever in the kitchen. By using the entire leek, nothing goes to waste. The tender white and pale green parts melt into the broth, while the darker tops get crisped up in the bacon fat into a crunchy garnish. I will often add crispy bacon for extra depth and saltiness, but it is completely optional if you would like to keep things lighter or vegetarian.

And of course, no bowl of soup is complete without something for dunking. My go to is crusty bread or homemade focaccia fried in plenty of olive oil until golden and irresistible. But you could also serve this with some garlic bread for a little extra indulgence. While potato and leek is a true classic, I also adore making roasted tomato soup, pumpkin soup and garlic confit soup when the cooler months roll in.

Why You'll Love This Recipe

  • Uses the entire leek (and bacon fat) so nothing goes to waste
  • Creamy, comforting and perfect for chilly evenings
  • The dark green leek tops and bacon become a golden, crispy garnish
  • Easy to make with simple ingredients you already have at home
  • Delicious served with crusty bread fried in olive oil for dunking

Ingredients for Potato & Leek Soup

Once you have your leeks and potatoes on hand, the rest of this soup comes together with just a handful of simple ingredients. And while the bacon and olive oil fried bread are optional, they turn this humble potato and leek soup into something really special.

  • Leeks – Choose firm leeks with bright white stems and fresh green tops. Rinse them well as dirt can hide between the layers. Use the tender white and pale green parts for the soup base and slice the darker green tops thinly to crisp up for garnish.
  • Potatoes – Waxy potatoes like Desiree, Yukon Gold or Dutch Cream hold their shape beautifully and create a creamy, velvety texture without turning gluey.
  • Garlic – I like to roast a whole bulb of garlic (this is a Daen's Kitchen recipe after all). But you can replace this with 4 raw garlic cloves that are minced if you want to save on time!
  • Stock – Use a good quality vegetable or chicken stock
  • Bacon (optional) – Fry until golden and crispy for a salty crunch that pairs perfectly with the sweet leeks and creamy potatoes.

A full list of ingredients can be found in the recipe card below.

How To Make

Can I make potato and leek soup ahead of time?

Yes, this soup keeps beautifully. Make it a day or two in advance and store it in the fridge. The flavours deepen overnight, making it even more delicious the next day.

What kind of potato is best for potato and leek soup?

Waxy potatoes such as Desiree, Yukon Gold or Dutch Cream are best. They cook down into a smooth, creamy texture without turning gluey. But really any potato will do!

Do you use all parts of the leek in this soup?

Yes. The tender white and pale green parts melt into the soup, while the darker green tops can be sliced and crisped up for a golden garnish. This makes the recipe zero-waste and full of flavour.

Is bacon necessary in potato and leek soup?

Not at all. Bacon adds a salty crunch and smoky flavour, but the soup is just as delicious without it if you prefer a vegetarian version.

What else can I garnish this soup with?

The options are endless! From Chilli flakes, parmesan cheese to some some truffle oil.

How To Serve

Potato and leek soup is best served piping hot with something perfect for dunking. I love pairing it with my homemade garlic bread, a gooey cheese toastie or a slice of freshly baked focaccia. Each adds its own delicious touch and turns a simple bowl of soup into a complete, comforting meal.

How To Store

Allow the soup to cool completely before transferring it to an airtight container. It will keep in the fridge for up to 3 days. When reheating, warm it gently on the stove and add a splash of stock or water if it has thickened. For longer storage, you can freeze the soup for up to 2 months. Defrost overnight in the fridge before reheating.

Potato and Leek Soup

On chilly evenings, nothing beats a classic potato and leek soup.
Prep Time: 5 minutes
Cook Time: 45 minutes
Servings: 4

Ingredients 

  • 2.2 lbs white potatoes, peeled and quartered
  • 2 leeks
  • 1 bulb of garlic, or 4 garlic cloves, minced
  • 4 tablespoon butter
  • 2 ½ tablespoon olive oil
  • 1 L chicken or vegetable stock
  • 7 oz streaky bacon
  • 1 cup heavy cream, optional
  • 1 baguette, sliced

Instructions 

  • Preheat oven: If roasting the garlic do this step - Preheat the oven to 200°C/ 390°F
  • Roast garlic: Cut the top off the garlic bulb roughly 2cm down from the top so the cloves are exposed. Place the garlic into an oven proof dish and season with ½ tablespoon olive oil and a generous amount of salt and pepper. Bake for 1 hour. Leave the garlic to cool then squeeze out the cloves.
  • Prep: Slice the green tops off the leek, finely dice and set to the side. Finely dice the white and pale green parts of the leek.
  • Fry and simmer: In a large pot on a medium – high heat, melt the butter. Add two tablespoons olive oil and leeks and cook for 10 minutes until soft and sweet. Add the potatoes, stock, garlic cloves and a generous amount of salt and pepper. Bring to the boil then cover and turn the heat to low or until the soup is at a gentle simmer. Simmer for 30 minutes or until the potatoes are soft and cooked through.
  • Fry bacon & leek tops: In a cold fry pan, add the bacon. Turn the heat to high and cook for 3 -4 minutes on each side or until crispy. Remove the bacon from the pan, ensuring you leave all of the fat behind. Turn the heat to medium and add the leek tops. Sautee for 5 minutes or until soft.
  • Fry baguette: On a grill plate or large fry pan on a low – medium heat, drizzle the baguette slices with the remaining olive oil and cook for 5 minutes on each side or until golden and crispy.
  • Blend: Take the soup off the heat. Using an immersion blender, blend until smooth. Season with salt and pepper and stir through cream if using.
  • Garnish: Top with crispy bacon bits and fried leek tops. Serve with olive oil fried bread.

Notes

  • Blend until smooth: Bring out the delicate flavours by blending your soup down to a smooth consistency. The potatoes should be nice and tender in the stock, making it easy for you to blend with a stick blender.
  • Leeks – Choose firm leeks with bright white stems and fresh green tops. Rinse them well as dirt can hide between the layers. Use the tender white and pale green parts for the soup base and slice the darker green tops thinly to crisp up for garnish.
  • Potatoes – Waxy potatoes like Desiree, Yukon Gold or Dutch Cream hold their shape beautifully and create a creamy, velvety texture without turning gluey.
  • Garlic – I like to roast a whole bulb of garlic (this is a Daen's Kitchen recipe after all). But you can replace this with 4 raw garlic cloves that are minced if you want to save on time!
  • Stock – Use a good quality vegetable or chicken stock
  • Bacon (optional) – Fry until golden and crispy for a salty crunch that pairs perfectly with the sweet leeks and creamy potatoes.

    I've made this soup so many times and love it so much! Thank you!

  2. Annette says:

    My family loved this soup! I especially liked that the bacon and green leek tops add some substance to the soup by not being blended in. Will be adding this to my repertoire.
    As a side note: I appreciate the metric units as I love to use my kitchen scale.

  3. Sarah says:

    How well would this freeze without any dairy? Thank you!

    1. daenskitchen says:

      It would freeze beautifully!

  4. Raven says:

    We have made it twice (without cream) and it's our favorite soup right now. I'm lucky enough to have a Vitamix and it gets creamy and luxurious. Speaking of luxury, the truffle oil drizzle is 🤌

    1. daenskitchen says:

      I am so glad you like it!

    Appreciate the recommendation. Let me try it out.

  6. Dulcie says:

    Instead of cream could I use Greek yogurt to finish it off or would it just split?

    1. daenskitchen says:

      You could add a little dollop on top at the end! You could also just leave out the cream or yoghurt as it's still super creamy without it

    I’ve tried over and over to pin this recipe for potato and leek soup but it doesn’t work… hmm, it says the link is broken.

    Can you check?

    Thanks,
    Susie

    1. daenskitchen says:

      I will look into this for you!

  10. Lmc says:

    Only problem is the ingredient list needs to be in ounces and spoonfuls in the U.S. We don’t use the metric system for recipes in U.S.

    1. daenskitchen says:

      I will work on providing my recipes in Imperial measurements!

    2. Miaa says:

      Just google the equivalent quantity in US measurements? Not like we don’t do the same from US to metric…

    3. Rc says:

      Seriously? Just look online for conversions.
