A cozy, soul-soothing creamy potato leek soup topped with crispy prosciutto and fresh chives, perfect for chilly evenings and quick weeknight dinners.

Ingredients

Scale
  • 3 large leeks, white and light green parts only, thoroughly cleaned and sliced
  • 2 pounds Yukon Gold potatoes, peeled and diced
  • 3 tablespoons unsalted butter
  • 2 cloves garlic, minced
  • 4 cups (1 liter) low-sodium chicken or vegetable broth
  • 1 cup (240 ml) heavy cream
  • 6 slices prosciutto, thinly sliced and crisped
  • 2 tablespoons fresh chives, finely chopped
  • Salt and pepper to taste
  • Optional: pinch of nutmeg or smoked paprika

Instructions

  1. Clean and prep the leeks: Slice the white and light green parts thinly. Rinse thoroughly in cold water to remove grit and drain well.
  2. Sauté the leeks: Melt 3 tablespoons of unsalted butter in a large heavy-bottomed pot over medium heat. Add sliced leeks and a pinch of salt. Cook gently for 10-12 minutes until soft and translucent.
  3. Add garlic and cook for 1 minute until fragrant, not browned.
  4. Add diced potatoes to the pot, stirring to coat with butter and leeks. Pour in 4 cups of broth. Bring to a boil, then reduce heat and simmer for 20-25 minutes until potatoes are fork-tender.
  5. Remove from heat and puree the soup using an immersion blender until smooth but leaving some small chunks for texture. Alternatively, blend in batches in a regular blender and return to pot.
  6. Stir in 1 cup heavy cream. Season with salt, pepper, and optional nutmeg or smoked paprika. Adjust seasoning to taste.
  7. Crisp the prosciutto: Heat a non-stick skillet over medium heat. Cook prosciutto slices 2-3 minutes per side until crispy. Drain on paper towels.
  8. Serve soup hot, topped with crumbled crispy prosciutto and fresh chopped chives.

Notes

Do not rush sautéing the leeks to develop sweetness. Add cream after removing from heat to prevent curdling. Crisp prosciutto carefully on medium heat to avoid burning. Adjust salt carefully as prosciutto adds saltiness. Add fresh chives last to preserve flavor.
