Thick and creamy, this celery and leek soup is a perfect comfort food for chilly days.
The addition of potatoes and rice thicken the soup and keep it naturally gluten free.
This soup is really easy to make too. Just chop the vegetables and get cooking.
And the best bit? The soup will be ready in 30 minutes.
Leek and potato soup or vichyssoise, is probably the most famous French soup but there are so many other variations and they are all easy to make.
This leek and celery soup is also known as potage Celestine. It's thickened with rice and potato, which release their starches into the soup as it cooks.
The delicate flavour of the leeks go so well with the celery too. The flavour is milder when the celery is cooked. This also means that you can use old celery, that may be stringy, as the soup will be pureed smooth.
Like vichyssoise, this soup can be eaten hot or cold, which makes it perfect for making in advance for entertaining.

⏲️ Cooking time

Stir in the milk and reheat if serving immediately or leave to cool and reheat when you are ready.
💭 Top Tip
- If you choose to use a full size blender, only fill it two thirds full as hot liquid expands in volume and can spill over.
Garnish the soup with a drizzle of cream, the chopped celery fronds, a grind of black pepper and some croutons.
- Leeks - replace the leeks with the same weight of mild onions if you prefer.
- Rice - switch brown rice for white rice to add more fibre to the soup and increase the cooking time accordingly.
- Leek and potato soup - leave out the celery and rice and use an extra leek. Add 140 ml or a quarter of a pint of single cream before serving cold to make vichyssoise soup.
- Celery - omit the rice and replace with 110 g, (4 oz), of watercress and add to the soup 15 minutes after the potatoes have been added.
Let the soup cool to room temperature then cover and store in the fridge for up to 5 days.
Freeze the soup in containers for up to 3 months.
Defrost then reheat gently in a saucepan.
The whiter and light green parts of the leek are best for eating. The dark green parts tend to be tougher. Give them a good wash and use them to make stock instead.
Celestine is a first name meaning heavenly in English.
The name appears regularly in French recipes such as Consommé Celestine, which has a Celestine garnish of finely shredded pancakes and Poulet Celestine, which was created in honour of a lady of the same name.
