Leek & Potato Soup is a classic creamy soup with sautéed leeks, a hint of garlic and tender potatoes. I love how a few simple ingredients can be blended together to make something that tastes extra special.
Great for a tasty lunch, or serve it with crusty bread for a warming dinner.

Cold evenings are made 100% better with creamy, filling, comforting leek and potato soup, served up with a big wedge of bread.
You can go down the vegetarian route – by using vegetable stock. Or to add a little extra oomph, you can use chicken stock. Homemade chicken stock is delicious for a real luxury feel, but good old stock cubes work really well too.

📋 Ingredients

- Leeks – 3 large leeks or 4-5 smaller leeks. We’re using just the white parts and the light green parts of the leek – you’ll need about 750g (just over a pound-and-a-half) of sliced leeks altogether. Be sure to check the leeks aren’t dirty or filled with grit. Sand and soil can get right down in the leaves, so give them a good rinse to remove any dirt.
- Use floury potatoes – such Maris Piper or red-skinned Rooster potatoes. Floury potatoes work better than waxy potatoes, as they break down more smoothly and give a creamier taste.

***Full recipe with detailed steps in the recipe card at the end of this post***
- Soften sliced onion and leeks in a large saucepan in a little butter. Add in seasoning (I use garlic salt, salt and pepper) and minced garlic – and give it a stir.
- Add in potatoes and stock, then bring to the boil and simmer for 20 minutes.
- After 20 minutes, the potatoes should be fall-apart tender. I like to scoop out a little bit of leek and potato at this point to top the soup with at the end.
- Blend the soup until JUST SMOOTH with a hand blender. Don’t blend for longer than needed, as the potatoes can become gluey.
- Stir in cream and reheat the soup again if needed.

- Serve the soup topped with the reserved leeks and potatoes. I also like to add a few chives, a little black pepper and a swirl of cream.

Pro Tip
You can use Homemade Chicken Stock to add a little extra flavour to the soup.
A French classic that tastes deliciously rich with cream and butter.

I rarely write reviews but this was so good that I had to.
I started making soups to take to work for lunch.
I tried a few soup recipes from your website and they are all spot on.
This soup I made today, and it was amazingly delicious .
What I’ve come to expect of these recipes: absolutely delicious!!
Perfect seasoning and state that will make the perfect cozy, winter warmer for lunch
This is beautiful 🤩. I have made a lot of leek/potato soup and this is definitely the best! I used my homemade chicken stock, leeks out the garden (the best!) and added some Stilton. I tasted it before and after the Stilton and both were so yummy 😋 I can’t thank you enough for such amazing recipes. 🙏
Easy to make and delicious to eat.
Sooooo good!!!
As usual bees knees
Makes a luxurious, tasty and very satisfying soup – a real family favourite that I make regularly.

This has always been one of my favourite soups to make, I love the little extras in your version. The little cubes of potatoes on the top and chives made all the difference😋
