Potage Parmentier
There are few colder-weather dishes more reassuring than potato leek soup, though “Potage Parmentier” admittedly sounds far grander than what it actually is: potatoes, leeks, stock, cream, and a little patience at the stove.
The soup takes its name from Antoine-Augustin Parmentier, the 18th-century French agronomist who spent years championing the potato as a safe and valuable food source at a time when much of France viewed it with suspicion. Potatoes were considered peasant food at best and dangerous at worst, associated with disease, poverty, and livestock feed. Parmentier devoted much of his career to changing public opinion, hosting elaborate dinners featuring potato dishes for aristocrats and even supposedly stationing guards around potato patches to convince the public the crop was valuable enough to steal.
Eventually, it worked. The potato became not merely accepted but foundational across French and European cooking, and dishes like Potage Parmentier emerged from that shift: economical meals elevated through care rather than luxury.
The version printed in the November 1921 issue of American Cookery reflects a moment when French-inspired home cooking occupied a particular aspirational place in American kitchens. Originally founded as Boston Cooking School Magazine under the influence of Fannie Farmer, the publication introduced readers to recipes that balanced practicality with a faint air of refinement. The appeal was not extravagance, exactly, but the promise that ordinary ingredients could be transformed into something elegant enough to serve guests.
And that remains the enduring charm of Potage Parmentier. It is, at heart, still potato soup, inexpensive, filling, deeply simple, but one softened by leeks and cream into something unexpectedly velvety. In an era when many “elevated” recipes require specialty ingredients and expensive pantry shopping, there is something refreshing about a dish whose luxury comes primarily from texture and warmth.
The original recipe leans heavily on technique common to its time: straining vegetables through a colander, thickening broth manually with flour and butter, finishing with cream and browned croûtons. Modern kitchens allow for a gentler approach. An immersion blender accomplishes in moments what once required considerable labor, while Yukon Gold potatoes create a naturally creamy consistency without much intervention at all.
Served with toasted bread and butter, Potage Parmentier is the sort of meal that makes cold weather easier to tolerate. It’s inexpensive, adaptable, and built almost entirely from pantry and refrigerator staples, which likely explains why versions of it have endured for generations.
Potage Parmentier
Serves 4–6
Ingredients
2 tablespoons butter
2–3 medium leeks, white and light green parts only, thinly sliced
4 large Yukon Gold potatoes, peeled and diced
4 cups chicken or vegetable broth
1 cup heavy cream
Salt and white pepper, to taste
Fresh parsley, chopped
Cubed and fried or olive-oil soaked and baked bread
Directions
Melt the butter in a large pot over medium heat. Add the leeks and cook until softened and lightly golden, about 5–6 minutes.
Add the potatoes and broth. Bring to a boil, then reduce heat and simmer for about 20 minutes, until the potatoes are very tender.
Blend the soup until smooth using an immersion blender, or carefully transfer in batches to a standard blender.
Stir in the heavy cream and season with salt and white pepper to taste.
Ladle into bowls and top with fresh chives and croûtons or toasted bread.
To Serve
The soup can also be served slightly cooler the following day, when the flavors deepen and the texture becomes even silkier.
