Creamy, comforting, and timeless, Julia Child’s Potage Parmentier, or Potato Leek Soup, is a classic French dish that strikes the perfect balance between simplicity and sophistication. This velvety soup is made from humble ingredients like leeks, russet potatoes, and water, yet achieves a luxurious texture and flavor with a touch of heavy cream or crème fraîche. Slow-simmered to tender perfection and blended until smooth—or left rustic for texture—it’s an adaptable recipe that suits any occasion. Garnished with fresh chives, a pat of butter, and a sprinkle of black pepper, it’s a visually stunning and deeply satisfying meal. Whether served as a starter or paired with crusty bread and salad for a fuller meal, this easy-to-make classic is a must-try for fans of hearty soups and French cuisine. Perfect for cozy nights or entertaining, it’s no wonder this Julia Child favorite remains a culinary icon.
Prepare the leeks by trimming off the dark green tops and roots. Slice the white and light green parts lengthwise, rinse thoroughly under running water to remove grit, and then slice thinly crosswise.
In a large, heavy-bottomed pot, combine the leeks, diced potatoes, water, and salt. Bring to a gentle boil over medium-high heat.
Once boiling, reduce the heat to low and simmer the soup uncovered for about 30 to 40 minutes, or until the potatoes and leeks are very tender.
Remove the pot from the heat. Use an immersion blender to puree the soup directly in the pot until smooth, or transfer the mixture in batches to a stand blender to puree. (Alternatively, leave the soup chunky for a rustic texture.)
Stir in the heavy cream or crème fraîche to add richness. Adjust seasoning with more salt if needed.
Ladle the soup into bowls and garnish with optional toppings such as a pat of butter, chopped chives, and freshly ground black pepper.
Serve warm with crusty bread or a side salad for a comforting and elegant meal.
