Potage Parmentier is a classic French potato-leek soup made with simple ingredients that create a rich, comforting flavor. This timeless French soup recipe turns everyday vegetables into a silky, satisfying bowl.
In a Dutch oven or heavy soup pot, melt butter over medium heat. Add leeks and garlic with a small pinch of salt. Cook 8–10 minutes, stirring occasionally, until very soft and fragrant but not browned.
Stir in the chopped baby potatoes, chicken, chicken broth, water, salt, and pepper.
Bring to a gentle boil, then reduce the heat and simmer uncovered for 20–25 minutes, until the potatoes are completely tender and easily pierced with a fork.
Stir in heavy cream, 1 teaspoon of Dijon, and 1 teaspoon of kalamata olive brine. Taste. Add more Dijon or brine a little at a time until the flavor is balanced and savory.
