Ingredients
  

Soup Base

  • 2 Tbsp unsalted butter
  • 2 Tbsp extra-virgin olive oil
  • 3 medium leeks (white and light green parts) cleaned and diced
  • 1 large yellow onion diced
  • 2 cloves garlic minced
  • 2 lb Yukon Gold potatoes peeled and diced
  • 6 cups chicken stock low-sodium or vegetable stock
  • kosher salt and freshly ground black pepper to taste

Finishing

  • 0.5 cup heavy cream optional
  • ground nutmeg pinch, optional

Instructions
 

Soup Base

  • Melt butter and olive oil in a large pot over medium heat. Add leeks, season with salt, and sauté until softened and golden around the edges, about 12 minutes.
  • Stir in onion and cook until translucent, about 5 minutes. Add garlic and cook until fragrant, about 1 minute.
  • Add potatoes and chicken stock. Bring to a boil, then reduce heat to simmer until potatoes are fork-tender, about 15–20 minutes.
  • Puree the soup in batches using an immersion or countertop blender until smooth. Return to pot.

Finishing

  • Stir in heavy cream and nutmeg, warming through. Adjust seasoning with pepper and more salt if needed.
