Potato Leek Soup

George Kutlenios • April 4, 2024

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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Remove the bay leaf and thyme sprig.
  6. 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.
  7. 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!

At The Holly Hotel, we believe in honoring the past while savoring the present, and one of our favorite ways to do that is with a timeless Wisconsin tradition: the Brandy Old Fashioned.

Updates on Holly Hotel Reconstruction! Deck the Halls with Boughs of Holly... For over 43 years, George and I have warmly honored Christmas at the Holly Hotel. In December, as tradition held, many of you walked through our doors with lovers, family, and friends to meet the fragrance of fresh pine, cinnamon, and delightful aroma from our kitchen. You've watched with swelling hearts the children's choir sing during dining. You have all been greeted with a sincere and heartfelt "Merry Christmas" as you stomped your snow-filled boots in our foyer, only to be instantly transported to Victorian hospitality. We strived to make you feel nostalgic, served, and satiated. It was our distinct pleasure. But not this year, nor last year...and most likely the 2024 Yuletide Season either! Our case continues to work its way through the legal system and, despite our efforts to place this case on a fast track, the court scheduled the trial for August 2024, if we can't resolve the case before then! We continue advancing our position that The Historic Holly Hotel should be entitled to rebuild its west-side wall. Were it not for a fire with an origin that was confirmed to be within the former Arcade building and were it not for the Arcade’s contractor destroying the west-side wall, we would not be in this situation. We will continue trying to move forward to the best of our ability. Many of you have asked how you could help. Your daily emails, antique donations, pictures of Christmases past, prayers, and good wishes fall warmly on our hearts. Thank you for supporting our efforts to reopen. Make Merry this Holiday Season!  George and Chrissy
