Creamy Leek Potato Soup (Printable Version)

A velvety blend of leeks and potatoes crowned with crisp sourdough croutons and fresh chives.

# Ingredient List:

→ Vegetables

01 - 3 large leeks (white and light green parts only), cleaned and sliced
02 - 3 medium russet potatoes, peeled and diced
03 - 1 medium yellow onion, diced
04 - 2 cloves garlic, minced
05 - 2 tablespoons fresh chives, chopped

→ Dairy

06 - 3 tablespoons unsalted butter
07 - 1/2 cup heavy cream

→ Liquids

08 - 5 cups vegetable broth
09 - Salt and freshly ground black pepper to taste

→ Croutons

10 - 2 cups sourdough bread, cut into 1/2-inch cubes
11 - 2 tablespoons olive oil
12 - 1/2 teaspoon dried thyme
13 - 1/4 teaspoon sea salt

# Steps:

01 - Preheat oven to 375°F (190°C).
02 - In a large pot, melt butter over medium heat. Add leeks, onion, and garlic. Sauté for 6-8 minutes until softened but not browned.
03 - Add diced potatoes and cook for 2 additional minutes.
04 - Pour in vegetable broth, season with salt and pepper, and bring to a gentle boil. Reduce heat, cover, and simmer for 20 minutes until potatoes are tender.
05 - While soup simmers, toss sourdough cubes with olive oil, thyme, and sea salt. Spread on a baking sheet and bake for 10-12 minutes, turning once, until golden and crisp.
06 - Remove soup from heat. Use an immersion blender to blend until smooth and creamy, or transfer in batches to a countertop blender and return to pot.
07 - Stir in heavy cream and gently reheat without boiling. Adjust seasoning as needed.
08 - Ladle soup into bowls, top with sourdough croutons and a sprinkle of fresh chives.

# Expert Advice:

01 -
  • It comes together in under an hour and tastes like you spent all day on it.
  • The sourdough croutons add a satisfying crunch that makes each spoonful feel intentional.
  • Silky, velvety texture without any heavy cream if you don't want it, though honestly, the cream makes it sing.
02 -
  • Blend the soup completely smooth—any chunks of potato left behind will make it feel incomplete, and you want that luxurious, pourable texture.
  • Don't boil the soup after you add the cream or it can separate and look weird; just gently reheat it on low heat while stirring.
03 -
  • Make the croutons while the soup simmers so everything finishes at the same time and they're still warm when you serve.
  • Taste the broth before you use it—some broths are much saltier than others, so season gently at first and adjust at the end.
