Potato Leek Soup
A Hotel Staple!

This soup has been around for centuries. A classic peasant soup, Julia Child (and so many others) have added their “spin” to this soup and my recipe is adapted from a combination of those methods and our recipe from the Holly Hotel. Potato Leek Soup and Tomato-Basil Soup were staples at the Holly Hotel, appearing often when we made our soups of the day.
One of main differences in this recipe is that it is dairy-free (i.e., no addition of butter or cream) and we often made these soups for guests who avoided dairy. It is, however, not gluten-free but can be easily adapted.
Ingredients
- 2 pounds of fresh leeks, white and light green parts only, washed and thinly sliced.
- 4 medium size russet potatoes, peeled and thin sliced
- 1 small onion or shallot, peeled and thin sliced
- 4 cups of vegetable stock (your own or a premium, low-sodium brand)*
- 1 bay leaf
- 1 sprig of fresh thyme or ¾ teaspoon of dried (or tarragon.) Waiting for Chrissy’s herb garden
- 1/2 teaspoon of Herbs de ‘Provence
- 1 slice of bold white bread (I use sourdough) very lightly toasted and torn into pieces
*While you are preparing your soup, you can make a simple vegetable stock by using the cleaned green leek parts, carrot peelings, onion peelings, celery peelings, etc. or whatever other vegetable scraps you may have been saving in a freezer bag for this purpose. If possible, start this earlier in the day, add a bay leaf, bring to a boil and then simmer for as long as you can before building your soup. ( “vegetable stock”)
Instructions
- Add two tablespoons of olive (or other) oil to your stock pot with the leeks and potatoes. Sweat the vegetables until they begin to get soft, about 4-5 minutes. (If dairy is not a concern, use 50/50 butter and olive oil.
- Slowly ladle just your stock into the hot stock pot with the potatoes and leeks in four batches, stirring constantly, until the soup comes to a rapid boil. Add the bay leaf and thyme, a little salt and pepper. Continue on medium heat until the potatoes become soft, about 10-12 minutes.
- If your soup looks too thin, let it continue to cook until reduced. If it is too thick, add a little more stock. You want a “stew” like consistency.
- Add the torn bread pieces to the pot, reduce heat to low/sim and allow the bread to become completely absorbed, about another 10 minutes. Stir occasionally.
- Remove the bay leaf and thyme sprig.
- Blend the soup in batches in a blender or use a stick, or immersion, blender. I prefer immersion blenders because regular blenders tend to “whip” up too much of the potato starch, thus making it gummy. Return blended soup to stock pot.
- Hold at simmer, test for salt. Garnish and serve.
You can make a nice garnish by thinly slicing your leftover and washed green leek leaves, dried thoroughly, and tossed with a spray of olive oil, a little flour, salt and pepper. Fry them well until they become brown and crisp. They should be matchstick size. Garnish atop of soup. Well-done bacon crumbles are also a nice garnish.
I miss making this for our guests.
Enjoy!
