Make this creamy potato leek soup for a satisfying, comforting meal. This easy recipe uses simple ingredients and creates a velvety texture perfect for chilly evenings.

Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 3 large leeks, white and light green parts only, sliced
  • 2 cloves garlic, minced
  • 1.5 pounds Yukon Gold potatoes, peeled and diced
  • 4 cups low-sodium chicken or vegetable broth
  • 1 teaspoon salt
  • 0.5 teaspoon black pepper
  • 0.5 cup heavy cream (or full-fat coconut milk for dairy-free)
  • Optional Garnish: Bacon bits, fresh chives

Instructions

  1. Melt the butter in a large pot or Dutch oven over medium heat.
  2. Add the sliced leeks and cook slowly, stirring occasionally, until they are soft and translucent, about 8 to 10 minutes. Do not let them brown.
  3. Add the minced garlic and cook for 1 minute until fragrant.
  4. Add the diced potatoes, broth, salt, and pepper to the pot.
  5. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer until the potatoes are very tender, about 15 to 20 minutes.
  6. Remove the pot from the heat. Use an immersion blender to blend the soup until it is completely smooth and velvety. Alternatively, carefully transfer the soup in batches to a standard blender and blend until smooth, returning it to the pot.
  7. Stir in the heavy cream. Heat the soup gently over low heat until warmed through, but do not let it boil after adding the cream.
  8. Taste and adjust salt and pepper as needed.
  9. Serve hot, garnished with bacon bits or fresh chives if desired.

Notes

  • For a rustic potato leek soup variation, skip the blending step and leave the soup chunky.
  • To adapt this for a slow cooker, sauté the leeks and garlic on the stovetop first. Transfer to the slow cooker with potatoes and broth. Cook on low for 6-8 hours or high for 3-4 hours. Blend and stir in cream before serving.
  • Use Yukon Gold potatoes for the best creamy texture.
