Ingredients
Method
- Melt the butter in a large pot over medium heat. Add the leeks and a pinch of salt; cook, stirring often, until soft and translucent, 5 to 7 minutes.
- Add the potatoes, stock, 1 tsp salt, and pepper. Bring to a boil, then reduce to a gentle simmer. Cook until the potatoes are completely tender, 15 to 20 minutes.
- Remove from heat. Use an immersion blender to purée until silky smooth. Stir in the milk or cream if using, then taste and adjust salt and pepper.
- Ladle into warm bowls and top with chives, a swirl of cream, or a pat of butter. Serve hot.
Notes
If you like a soup with a bit of texture, blend only half the mixture and stir it all back together. The soup naturally thickens as it cools, so when reheating leftovers add a splash of stock or milk to loosen it up.
