French Fridays with Dorie: Potato-Leek Soup

This starts the third month of French Fridays with Dorie. For those who don’t know what that is, it’s an online group that has set out to cook our way through Dorie Greenspan’s relatively new book, Around My French Table.

I’m really enjoying this cookbook and being part of this cooking community. So far, all of the recipes have been ones I wouldn’t have thought to make anyone, or they were versions of things I already make, but exposed me to a different way of doing it. I’ve eaten lots of good food and learned quite a bit along the way, both from Dorie’s book and from my fellow bloggers from FFwD.

As in November, in the holiday-laden month of December, there are five recipes to be cooked, but I can pick the order that works best for me. I had a beautiful bunch of leeks from our Winter CSA share, so I selected the Potato-Leek Soup.

I’ve been making James Beard’s recipe for potato-leek soup from American Cookery for many years. However, I was willing to try to make Dorie’s French version.

The recipe gives options to tweak this soup in many ways. The choices I made were to substitute leeks for the onion because my bunch of leeks was big enough. I also went with the chicken broth and milk instead of water, though I used 1% instead of whole milk. As for the final texture, I love an excuse to use the food mill, so I pureed it for a very smooth soup.


I loved the velvety texture. I think it would work well as an appetizer soup, though it will also be good for lunch. The soup was an easy recipe, and with the different choices you can make, it can be a different soup the next time. My verdict: Très Bien!

Lexington Leeks

Full-Grown Leeks in Our GardenI belong to the Lexington Field & Garden Club .  Every year, the garden club and the Lexington Historical Society sponsor a joint program for their members.  This year’s lecture took place back in April.  The featured speaker was Russell Morash, a fellow Lexington resident, and producer of some of my favorite PBS shows.  He produced Julia Child’s first show The French Chef as well as This Old House, The New Yankee Workshop, and The Victory Garden. 

Mr. Morash gave an entertaining presentation.  The first part of his talk and slide show was about the history of making The Victory Garden TV show.  The second part of his talk was about his own passion for his vegetable garden. 

After the talk, there was a raffle.  There were several prizes, and each winner got to pick from the available selections.  I was hopeful that I would win and be able to pick the copy of Marian Morash’s (the speaker’s wife) cookbook, The Victory Garden Cookbook.  My own copy, which I’ve had since college, is falling apart.  No such luck. 

The last prize left was a pot of leek seedlings that Mr. Morash had started from seed.  And, they drew Howard’s number, so he won the pot of seedlings!  He planted them in the garden, and we’ve had a good crop.  (There are still a few in the garden.) 

Using the leeks from our garden, I’ve made a variety of leek tarts and a leek custard when there was too much filling for the crust.  Here’s the best of what I’ve tried so far.

Leek Tart

Leek Tart (Serves 6)
Adapted from “Ready When You Are” by Martha Rose Shulman

  • 1 batch of your favorite pastry crust
  • 2 Tbsp butter
  • 5 cups sliced leeks, white and light green parts only (about 3 leeks, but it will depend on their size)
  • 3 large eggs
  • ¼ cup cream
  • ¼ lb Black Forest ham, chopped
  • ¼ lb Gruyere cheese, grated

Preheat the over to 400F.  Roll out the crust and line an 8-inch springform pan.  Prick the bottom with a fork and chill while you prepare the filling (or longer, if you want to prepare the crust ahead of time).

Line the crust with parchment paper or foil, then fill with beans.  Partially bake the crust for 10 minutes. It won’t be brown.

Melt the butter over medium heat in a large skillet. Add leeks. Cook, stirring as needed, until the leeks begin to soften, about 5 minutes. Cover the pan, turn heat to low, stirring occasionally, and cook for 15 more minutes, until very soft. Add salt & pepper to taste and remove from the heat.

Beat the eggs. Add milk, salt & pepper. Stir in the leeks, ham, and ¾ of the cheese. The filling mixture will be thick, definitely not as custardy as a quiche. Transfer the filling to the partially baked crust. Sprinkle with the remaining cheese.

Bake for 45 minutes, until the top is browned. Serve warm with a green salad.
