Creamy Leek Potato Soup (Printable Version)

Velvety blend of leeks and potatoes topped with crunchy sourdough croutons and fresh chives.

# What You Need:

→ 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. Toss sourdough cubes with olive oil, thyme, and sea salt. Spread on baking sheet and bake for 10–12 minutes, turning once, until golden and crisp.
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 to the pot and cook for 2 more 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 - Remove soup from heat. Use an immersion blender to blend until smooth and creamy, or transfer in batches to a blender and return to the pot.
06 - Stir in heavy cream and gently reheat without boiling. Adjust seasoning as needed.
07 - Ladle soup into bowls, top with sourdough croutons and a sprinkle of fresh chives.

# Expert Advice:

01 -
  • It tastes like restaurant quality but takes barely an hour from start to finish.
  • The contrast between velvety soup and crispy croutons is honestly addictive.
  • One pot, one blender, and you've got something that feels fancy enough to serve guests.
02 -
  • Blend it completely—any visible chunks and it won't feel like the silky soup you're after, which I learned the hard way by being too cautious.
  • Don't skip cleaning the leeks properly by slicing them lengthwise first and rinsing between layers, or you'll find grit in every spoonful and regret it.
03 -
  • Make the croutons first and let them cool while the soup simmers—they stay crispier that way and don't get soggy.
  • Save leftover soup in the fridge for four days, and the flavors actually deepen and become more mellow over time.
