Potato Leek Soup with Herb Flavored Sea Salt & Truffle Oil

Potato leek soup is my friend Rose’s signature soup. Rose makes it every time she has a gathering, and it is always a big hit. Rose usually serves her potato leek soup with a side of lavender & herb-flavored sea salt and truffle oil, which transforms an already delicious soup into something decadent.



Here is a recipe for a very yummy, creamy potato leek soup courtesy of my friend Rose.

  • 2 tbsp unsalted butter
  • 1 medium onion, thinly sliced
  • 3 leeks, sliced
  • 3 large baking potatoes ( I use Yukon), peeled and cut into 1/4-in thick slices
  • 3 (14 1/2-oz) cans vegetable broth
  • 1tsp salt
  • 1/4 tsp pepper
  • For Toppings: shredded cheddar cheese, crumbled cooked bacon, chopped fresh chives, sea salt herbs de Provence, truffle oil (all optional)


  • Melt butter in a large saucepan over low heat; stir in onion and leeks.  Cover and cook for 20 minutes, stirring occasionally.
  • Next add potatoes; cover and cook for 15 minutes. Add in broth, salt and pepper and bring to a boil.  Reduce heat and simmer for 30 minutes or until potatoes are tender.  Remove from heat and cool slightly.
  • Process soup in batches in a blender or with an immersion stick blender, until smooth (or to your liking).   Return to saucepan and cook over medium heat until thoroughly heated.
  • Serve with seasoned sea salt and truffle oil.
