Leek and Potato Soup

Recipe video above. Thick and creamy Leek and Potato Soup, a French classic. Few ingredients, prepared well, and it's just so enjoyable to eat. TOP TIP: Do not over blitz the soup, it activates the starch in the potato and will give your soup an unpleasantly sticky mouthfeel. This is a mistake commonly made in recipes that instruct to blitz, blitz, blitz!

Sauté - Melt butter in a large pot over medium heat. Add garlic and leek and sauté for 7 minutes until soft and sweet.
Simmer 25 minutes - Add potatoes and broth. Turn heat up and bring to simmer, then place lid on and lower heat so it's simmering gently. Simmer for 25 minutes or until potato is very soft and almost falling apart.
Minimal blitz - Turn the stove off and puree with a stick blender until JUST smooth. Do not over puree (Note 3).
Season - Add salt and pepper, then stir through cream.
Serve, drizzled with cream and sprinkled with chives and croutons.
Croutons
- Preheat oven to 180°C/350°F (160°C fan-forced). Drizzle bread with melted butter (or spray with oil). Bake for 5 minutes or until golden and crunchy. Sprinkle with a pinch of salt while hot!

Well we just felt like leek and potato soup today and as I was googling recipes, I was hoping you would have one, Nagi. Everything I make of yours is always 10/10! Sure enough, there is was and, once again, delicious! Thank you for such clear recipes and always great explanations for everything. 🤗🌼🌼

Nagi, definitely 10 out of 10. Top notch soup with rave reviews. I used homemade chicken stock that I had which added a fair amount depth and richness. I also opted to use a little bacon fat with the butter to saute the leeks!

Firstly, sincere condolences for Dozer. What a delight he was. Thank you for sharing him with us. I love this recipe. I make it a lot. The only difference is I also add one onion to further boost the flavour. My question relates to freezing and fridge time. I am a single person household. How long will this keep in the fridge and can it be frozen? I know freezing potatoes can be iffy. Many thanks.

EXCELLENT!! I ended up using the greens from the leeks, half chicken mixed with half vegetable broth and I used white potatoes An immersion blender makes it creamy

The first soup I have ever made, inspired by someone else who made Potato and Leek soup. This is delicious!! I've added cooked bacon and also put in more leek and garlic.... Delicious!!! Especially with crusty fresh bread. Mmmmmmmm

Delicious soup! Thank you!! I wash my leek tips well and long sauté them. Then I make a roast pumpkin and marinated feta fettuccine. So delicious! Don’t throw them away! They are the best bit, prepared well!

I enjoyed this a lot as is, but I have to confess it gave me dirty thoughts of adding cheese and bacon bits.
Alex on 2025-08-25 (5 stars):
First time I've ever made soup. Tasted great. Easy to make. Thanks Nagi.
Trish K on 2025-08-17 (5 stars):
Honestly you could serve this in a fancy restaurant and charge top dollar...it's hands down the easiest and most delicious soup. I love everything Nagi makes, she's my food Goddesses.
Hanna on 2025-08-07 (5 stars):
Thank you for another great recipe. I came to check the ratio of potatoes to leeks. I've always made my leek and potato soup the same as your recipe except I finish my soup with a Liaison of blended egg yolk and cream (passed through a sieve). It gives the soup a beautiful smooth finish. I also like to use chicken stock, and always sweat the leaks in butter.

I bought 2 big fat leeks at the farmers market - made for much more than 2 cups but it all went in!! I LOVE potato leek soup and the leek-ier the better!
Kristen Garth on 2025-07-20 (5 stars):
This soup is Devine , soft and silky smooth. I’ve made it just about every weekend ! And never goes to waste. I have added some crispy bacon on the top and it takes it next level ! Yum Thanks Nagi
