This easy leek and potato soup recipe is creamy, comforting and ready in about 30 minutes. Made in one pan with inexpensive everyday ingredients, it is the kind of simple lunch I come back to as soon as the weather turns colder. Even better, my kids love it too.
The potatoes make the soup naturally thick and creamy, so you only need a small amount of single cream - and you can leave it out altogether if you prefer. I usually make extra because it reheats so well, which means lunch is already sorted for another day.
For children, I use a low-salt vegetable stock and leave the final seasoning until the soup is in the bowls. Add some crusty bread or garlic bread for dipping and it becomes a really easy family lunch.
Recipe update: This recipe was originally published on 30 October 2017 and was fully retested in September 2026 to check the cooking time and ingredient quantities. The original recipe still worked well, but I've expanded the instructions, tips and FAQs.
It's also a great way to use up leeks when they are in season. Why not also try our quick Leek Risotto, comforting Chicken and Leek Pie or our easy Creamy Leek Pasta?

Ingredients and Substitutions
A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Potatoes - Floury potatoes are best for leek and potato soup because they soften easily and give the soup a naturally creamy texture. I usually use Maris Piper or Rooster potatoes.
Waxy potatoes will still work, but they do not break down in quite the same way and can give the soup a different texture.
The biggest thing to remember is not to over-blend the potatoes. Too much blending releases the starch and can turn an otherwise creamy soup sticky or gluey. - Leeks - Use fresh leeks that feel firm and wash them thoroughly, as soil can hide between all the layers.
The white and pale green parts have the softest texture for the soup. You don't need to waste the darker green tops: wash them well and keep them for homemade vegetable stock. - Shallots - Shallots add a gentle sweetness that works really well with the leeks. A small brown onion is a perfectly good substitute.
- Butter - Butter gives the vegetables a little extra richness. For a dairy-free or vegan leek and potato soup, use olive oil instead.
- Single cream - You only need a small amount of single cream to make the soup feel a little more indulgent.
It is completely optional. The blended potatoes already make the soup thick and creamy, so you can make this leek and potato soup without cream and still get a lovely texture.
Crème fraîche or a splash of milk can also be used instead. - Vegetable Stock - A good vegetable stock makes a big difference because this is such a simple soup.
If I am making it for the whole family, I use a low-salt vegetable stock and let everyone season their own bowl afterwards.
Chicken stock also works if you do not need the recipe to be vegetarian. - Chives (optional) - Chives are my favourite herb for leek and potato soup because their gentle onion flavour works so well with the leeks. Fresh parsley and thyme are both good alternatives.
How to Cut and Clean Leeks
Leeks can hide a surprising amount of soil between their layers.
Trim off the root, slice the leek lengthways and separate the layers slightly under cold running water. Once they are clean, slice the white and pale green sections.
Don't automatically throw away the darker green leaves. They are tougher, but they are excellent for adding flavour to homemade stock.
How to Make Leek and Potato Soup
- Soften the vegetables: Melt the butter in a large saucepan over a medium heat.
Add the shallots, sliced leeks and chopped potatoes and cook for about 5 minutes, stirring occasionally. You want the leeks to soften rather than brown.
- Add the stock: Pour in the vegetable stock and add a little black pepper.
Bring to a gentle simmer and cook for about 20 minutes, or until the potatoes are completely tender when pierced with a knife.
- Blend carefully: Take the saucepan off the heat.
Use a stick blender to blend the soup until smooth, stopping as soon as you reach the texture you want. Avoid blending for longer than necessary because over-blending potatoes can make the soup gluey.
⚠️ If you are using a jug blender, allow the soup to cool a little first and blend it in batches rather than filling the jug with very hot liquid.
- Finish and serve: Stir in the single cream, if using, then taste the soup and add salt and pepper as needed. Serve with chopped chives and plenty of black pepper.
💡 For extra texture, add homemade croutons, a little reserved sautéed leek or some crispy chopped bacon.
Variations
Dairy-free leek and potato soup - Cook the vegetables in olive oil instead of butter and leave out the cream, or use your favourite dairy-free alternative. Make sure your vegetable stock is suitable for vegans.
Family friendly - This is already a very mild soup, which is one reason it goes down so well in our house. When I am serving it to children, I use a low-salt stock and don't add much salt to the saucepan. Adults can add extra seasoning to their own bowls at the table.
You can also leave a little of the soup less thoroughly blended if your family prefers some texture. And if a bowl of greenish soup gets a suspicious look, garlic bread for dipping usually helps.
Leek and potato soup with bacon - Cook some chopped bacon until crisp and scatter it over the finished soup. I prefer keeping the soup itself vegetarian and offering bacon as an optional topping so everyone can have the same base recipe.
Chunky leek and potato soup - You do not have to blend the soup completely smooth. Blend only part of it and leave some soft potato and leek pieces for texture.
Can You Make Leek and Potato Soup Without Cream?
Yes. In fact, this is one of the easiest soups to make creamy without cream.
Floury potatoes naturally thicken the soup when they are cooked and blended, so simply leave out the single cream.
If you want a little extra richness without cream, you can add a splash of milk, an unsweetened dairy-free milk or a spoonful of dairy-free crème fraîche.
I like having the cream as an optional finishing touch rather than relying on it for the texture of the soup.
Is Leek and Potato Soup Healthy?
Leek and potato soup can make a filling vegetable-based lunch, particularly when it is made with plenty of leeks, potatoes and a lower-salt stock.
This version only uses a small amount of single cream for the whole pan, and you can leave it out completely. If you want to make the soup lighter, use olive oil instead of butter, omit the cream and choose a low-salt vegetable stock.
For a more substantial meal, serve it with wholegrain bread or another source of protein alongside it.
Serving Suggestions
There is nothing wrong with keeping it simple with a thick slice of crusty bread.
We also love it with homemade croutons. Cut bread into cubes, drizzle with a little olive oil and sprinkle with garlic granules and dried herbs, then bake until crisp. Or try my Air Fryer Croutons.
Garlic bread is always popular here, and homemade garlic and rosemary focaccia turns the soup into a more substantial lunch.
A little tip - when I have just a little leftover, not really enough for a bowl of soup, I turn it into a pasta sauce. It sounds odd, but it really works. Add some cream cheese to it and you have yourself a really cheesy pasta sauce.
Storage
How long does leek and potato soup keep in the fridge?
Allow the soup to cool, transfer it to an airtight container and keep it refrigerated for up to 2 days.
Can you freeze leek and potato soup?
Yes. This soup freezes really well, so I often make a double batch. Allow it to cool completely, portion it into freezer-safe bags or containers and freeze. I like laying freezer bags flat because they take up much less room once frozen.
How do you defrost leek and potato soup?
Defrost it overnight in the fridge before reheating.
How do you reheat leek and potato soup?
Reheat gently in a saucepan until piping hot. It will often thicken after chilling, so add a splash of stock or water if needed. If it has separated slightly after freezing, a good stir should bring it back together.
Dannii's Top Tips
- Use floury potatoes such as Maris Piper or Rooster for the creamiest result.
- Wash leeks thoroughly because soil gets trapped deep between the layers.
- Soften the leeks rather than browning them so their flavour remains sweet and delicate.
- Use a good-quality stock because there are only a few ingredients in this recipe.
- Use low-salt stock if serving the soup to younger children, then season adult portions separately.
- Use certified gluten-free stock to ensure this recipe is gluten free.
- Don't over-blend. Stop as soon as the soup is smooth.
- Use a stick blender if possible because it gives you more control than a jug blender.
- Keep the cream optional. The potatoes should provide most of the creamy texture.
- Make a double batch if you have a large enough saucepan - future you will be very pleased to find it in the freezer.
Troubleshooting Guide
|
Problem |
Likely cause |
Fix |
|
Soup is sticky or gluey |
The potatoes have been blended for too long, releasing too much starch. |
Unfortunately, you can't completely reverse this. Gently stir in a little warm stock to loosen the texture, but don't blend it again. Next time, stop blending as soon as the soup is smooth. |
|
Soup is too thin |
There may be a little too much stock, or the potatoes haven't thickened it enough. |
Simmer uncovered for 5-10 minutes to reduce it. If it is still too thin, add a little cooked potato and blend very briefly. |
|
Soup is too thick |
Too much liquid has evaporated, or the soup has thickened as it cooled. |
Stir in warm vegetable stock or water a little at a time until it reaches the consistency you like. |
|
Soup tastes bland |
Leek and potato soup has simple flavours, so weak stock or too little seasoning can make a big difference. |
Taste after blending and add salt and black pepper as needed. A good-quality stock and fresh chives also add plenty of flavour. |
|
Soup feels gritty |
Dirt may have remained between the layers of the leeks. |
Pass the soup through a fine sieve if needed. Next time, separate and rinse the leek layers thoroughly before slicing. |
|
Potatoes won't blend smoothly |
The potatoes aren't completely cooked. |
Return the soup to a gentle simmer until the potatoes are very soft when pierced with a knife, then blend briefly. |
|
Soup separates after freezing |
The small amount of dairy can separate slightly as it freezes and reheats. |
Reheat gently and stir well. For the best texture when batch cooking, you can also freeze the soup before adding the cream and stir it in after reheating. |
Frequently Asked Questions
I prefer to peel them for a very smooth soup. If you want a more rustic texture and the potato skins are thin and clean, you can leave them on.
Yes. Milk gives a lighter finish. Add it at the end and heat gently rather than boiling it aggressively.
Simply stir in a little more vegetable stock until it reaches your preferred consistency.
Chives are my favourite because their mild onion flavour works really well with the leeks. Fresh parsley is a good alternative, while thyme gives the soup a slightly more earthy flavour. If using dried thyme, add a small amount with the stock; fresh chives or parsley are best added just before serving.

Sarah Bailey says
There is something wonderful about soup in autumn, it is so warming and delicious, I definitely need to try potato and leek with chives it sounds perfect.
Tina says
Thanks for the review. When I work a lot, I don't have time to cook. Even an easy quick soup seems daunting. It's nice to know what good alternatives are out there. Let's be honest, is there any soup better than potato? I don't think so:)
Rachel says
This is my favourite soup, but I have never put chives in mine either. We are making the most of leek season and making variations of this a lot at the moment.
Angela says
I love that they actually challenged you to compare them. I guess that shows how confident they are in their product. We buy tonnes heinz soup quite a lot, but I haven't seen these cartons.
