If it seems cliché for me, a girl learning to cook, to want (and receive) a Julia Child book for Christmas, well, maybe it is. But, you know, not all clichés are bad.

That one about how a penny saved is a penny earned? I kind of like that one. And you’re only young once? That’s true, too.

Maybe you’re still working on refining your new year’s resolutions: Get in shape? Save more money? I say, what the heck! Let’s all embrace clichés this year.

Julia Child is kind of The Great Famous Chef, the one who brought French cooking to American domestics, who seemed so excited, so full of gusto, she made you believe you could cook whatever she could, even in your own little kitchen.

(And that voice! Was there ever anyone else so endearing?)

So, I wanted to own a copy of Mastering the Art of French Cooking, like over a million home cooks have before me.

When I finally got my hands on this treasured tome, I opened to the first chapter and set my hopes on preparing a pot of potage parmentier, or leek and potato soup.

Julia – we’re on a first-name basis now – says yellow onions are fine to use to sub for the leeks, and that’s what I had, so that’s what I used.

This is French food at its most economical. I would suspect you have all the ingredients on hand already, and surely you can find some time to prep and cook them and make something delicious.

The version that you see here was made with leeks, which have a more delicate and sweet flavor profile, but feel free to use onions instead if that’s all that you have in the pantry.

The results will be worth it: a creamy, comforting, steamy soup with small flecks of soft potatoes throughout. Julia says adding extra vegetables is fine, so I threw in a couple of diced carrots as well.

This gave my soup a pretty orange color reminiscent of pumpkin soup, and topped with a drizzle of cream and a sprinkling of chopped chives before serving, this soup looks as nice as it tastes. I ate two bowls immediately the first time I made it, and the next day, my family finished the rest.

You can serve it as a light lunch on its own, or make a fantastically French meal with this as the first course, then a warm and hearty poulet saute as the main course. No one will be left hungry, or disappointed!

In fact, though freshman year French class may be worlds away for me now, I feel as if Monsieur Shelbourne would be proud, bless his heart, that something’s finally clicked.

With Julia, suddenly everything French is fascinating to me. Like French macarons and madeleines, French restaurants, and even the movie Ratatouille (plus the actual ratatouille dish!).

French class didn’t stick for me, and I can see why. If only I’d known then what I know now: just give this girl a cookbook, and I’m ready to go on that journey, exploring a new culture through its delicious food.

Potage Parmentier (French Potato Leek Soup)

  • Author: Shanna Mallon
  • Total Time: 1 hour, 15 minutes
  • Yield: 6 cups (serves 4-6 people) 1x


Thanks to a modest yet intensely aromatic medley of buttery sauteed veggies, this warming potato leek soup is simple and satisfying.


  • 2 tablespoons unsalted butter
  • 1 pound Yukon gold potatoes, peeled and diced (about 3 cups)
  • 3 cups diced leeks, white and light green parts only (about 2 large)
  • 1 1/2 cups peeled and diced carrots (about 2 medium)
  • 2 teaspoons coarse salt, plus more to taste
  • 1 1/2 teaspoons freshly ground black pepper, plus more to taste
  • 8 cups low-sodium vegetable stock
  • 6 tablespoons whipping cream, plus about 2 tablespoons for garnish
  • 2 tablespoons minced fresh chives


  1. In a large saucepot or Dutch oven, melt the butter over medium heat. Add the potatoes, leeks, and carrots and season with the salt and pepper. Saute until very fragrant, about 3-5 minutes, then add the stock.
  2. Bring to a boil, then simmer partially covered until the vegetables are tender, about 45 minutes.
  3. Using an immersion blender (or transferring 3/4 of the mixture to a blender), puree the soup until it’s mostly smooth but still has a bit of texture. Season with additional salt and pepper to taste.
  4. Remove from the heat. Just before serving, stir in the cream a few tablespoons at a time. Ladle into bowls and garnish each with about 1/2 tablespoon cream and chives.

Cooking By the Numbers…

Step 1 – Rinse, Peel, and Dice the Potatoes, Carrots, and Leeks

Get out your vegetable peeler, a sharp chef’s knife, and your favorite cutting board.

Rinse and peel the potatoes and carrots, and dice them carefully so all of the pieces are about the same size, to facilitate even cooking.

Trim the roots and dark green tops off of the leeks, leaving only the light green and white parts. Slice them lengthwise and rinse them well under cool running water to remove any dirt trapped between the layers. Dice the leeks into equally-sized pieces.

For a more traditional potage parmentier that’s white instead of orange, you may choose to omit the carrots.

Step 2 – Saute the Veggies in Butter

In a large saucepot or Dutch oven, melt the butter over medium heat and swirl to coat the bottom of the pan.

Add the potatoes, leeks, and carrots and season them with the salt and pepper. Stir to combine. Saute the vegetables until they very fragrant, for about 3-5 minutes.

Step 3 – Add the Stock and Boil, Then Simmer

Pour in the stock. If you prefer, homemade vegetable broth makes a delicious addition.

Bring the soup to a boil, then reduce the heat and simmer it partially covered until the vegetables are tender, for about 45 minutes.

Step 4 – Blend Until Mostly Smooth

Using an immersion blender, puree the soup right in the pot until it’s mostly smooth, but with some chunks remaining to provide a bit of texture.

You could also transfer about 3/4 of the mixture to a high-speed blender and blend until smooth before transferring the puree back to the pot. Just be careful to avoid steam burns if you’re using a countertop appliance!

Season to taste with additional salt and pepper (freshly cracked is best!) as desired.

Step 5 – Chop the Chives and Stir in the Cream

Finely mince the fresh chives for garnish.

Remove the pot from the heat. Just before serving, stir in the cream a few tablespoons at a time until combined thoroughly.

Smells Good, Tastes Good, and Is Simplicity Itself to Make

Don’t quote me on that. That was all Julia Child. And when Julia says that something tastes good, you listen.

Though the most traditional version of potage parmentier (straight from Mastering the Art of French Cooking) calls for boiling the veggies in water, for my own version that came about as the result of some tinkering in my own kitchen, I take a different route.

Sauteeing the aromatics first deepens the overall flavor of the base, and the more flavor, the butter. Er, the better.

Craving all kinds of comforting bowls of soup after reading this? Here are some other standout recipes from Foodal:

To add another layer of flavor to this homemade soup, you can also toss in some fresh herbs with the veggies.

  1. how warm and hearty. i know you’re going to gasp out loud and may even break up with me but i have to admit, i can’t call myself a Julia Child fan. she doesn’t touch me the way she does with everyone else. growing up, it was the Frugal Gourmet, it was his show on PBS that i dug. i’m kinda ducking now.

    i am looking forward to what you create this year from her book, maybe you’ll convert me. 🙂

  2. GREAT post, Shannalee. I love that you and Julia are on a first name basis (my new BFFs are Dorie and Bitty), and girl, my Christmas list was chock full of cookbooks. I’d love to say that my resolution is to make it through How to Cook Everything by Bitty, but there are over 1000 pages with several recipes per page. Maybe by my 40th birthday?

  3. Lan: Convert you I shall! HA! Truth is, I liked Frugal Gourmet, too, so it’s cool: we can still be friends. Julia is really something, though. When I heard she’d done some spy stuff, worked for intelligence or whatever, I was like: I always knew it.

    Becky: Oui!

    Jacqui: Did you try out the stick blender yet? It is SO much fun. First of all, it’s so much more powerful than I expected. And I swear, between it and my KitchenAid and the dishwasher, my kitchen practically cooks and cleans for me.

  4. I love it!:) I tried the recipe and have made it 4-5 times by now!:) Its now a family fav! Especially since its SO easy to make!:P

  5. I have made this for years aftwr stumbling on this amazing book in an estate sale of retired restaurant owners.

    My husband enjoys meat in his soups so I start off by omitting butter in first step and chopping up lean thick bacon and sautéing the veggies with the bacon. After the veggies and bacon are cooked I strain off most of bacon drippings. Lots more flavor is introduced just by rendering the bacon while cooking the veggies. I find he enjoys a more rustic soup so I don’t typically use an immersion blender. However, one could prepare the original recipe and top it with diced cooked bacon as a topping.

  6. Mastering the art of French Cooking was not “written by Julia Child” but by two Frenchwomen, Simone Beck and Louisette Bertholle – and Julia Child. Credit where credit is due please.
