Ingredients

  • 4 tablespoons unsalted butter

  • 1 ½ pounds trimmed leeks, cleaned and thinly cut

  • 2 teaspoons kosher salt, plus more to taste

  • 1 ¼ pounds Yukon Gold potatoes, peeled, cut into eighths

  • 3 cups chicken or vegetable broth, or more as needed to adjust thickness

  • 1 cup heavy cream

  • ½ cup creme fraiche

  • 1 pinch cayenne pepper

  • Chopped fresh chives for garnish

Directions

  1. Melt butter in soup pot over medium-high heat. Add leeks and salt; cook until leeks begin to wilt. Reduce heat to medium or medium-low and cook until soft and almost pastelike, 30 to 40 minutes.

  2. Place potatoes in the pot; add chicken broth. Adjust heat so mixture simmers slowly. Cook until potatoes are soft, about 30 minutes. Puree mixture with an immersion blender or in batches in a blender. Whisk in heavy cream and creme fraiche. Heat over medium heat. Add more salt, if needed, and cayenne pepper. Do not boil.

  3. Serve with a drizzle of creme fraiche and a sprinkle of chopped chives.

Chef's Notes:

You'll need 1 1/2 pounds of leeks after they've been trimmed. Leave about an inch of the dark green.

Here's Chef John's recipe for homemade crème fraiche.
