Low Carb Christmas Eve Potato Soup (Made with cauliflower, but you’d never know it!)

It has been a tradition since I was a child to enjoy a particular heirloom recipe at this time of year, taught to me by my grandmother and simply known as Christmas Eve Potato Soup. Because it is only made once a year, it has remained a family favorite through several generations that is anticipated with joy and excitement, just like Santa Claus. It just wouldn’t be Christmas at my house without it! I have tried many times to reduce the carbs in this special recipe by substituting the potatoes with white beans, turnips or daikon radishes, but the result was always a bit disappointing...until now!! I was going to make the soup with fresh cauliflower florets this year, but then it occurred to me that frozen cauliflower already has been blanched, so it would impart a milder flavor. It turned out to be the perfect potato substitute! I chose frozen riced cauliflower and puréed it with the broth prior to adding it to the soup. Combined with the other ingredients, this low carb version is a winner in every way! Both my husband and daughter agree that it tastes just like the real thing. The best part? It only has 9 net carbs for a generous 2 cup serving! (Compared to the traditional recipe which has over 45 carbs for a smaller serving, it’s quite a reduction.) From now on, this low carb version will have a place of honor on my Christmas Eve dinner table!

Low Carb Christmas Eve Potato Soup (made with cauliflower)

Makes 4 servings

4 slices of bacon, diced

2 trimmed leeks, sliced into half moons

1/4 cup chopped onion

3 cups frozen riced cauliflower, thawed

4 cups chicken broth

1/2 teaspoon xanthan gum

2 beaten egg yolks

1 cup sour cream

1 teaspoon chopped parsley as a garnish

Salt and pepper to taste

1. In a large heavy pot, sauté the bacon until beginning to brown and crisp. Add the onion and leeks and continue to sauté for 5 minutes.

2. Purée the broth with the thawed riced cauliflower in a blender until smooth. Add the purée to the leek mixture and bring to a boil. Reduce heat to low and simmer, covered, for 20 minutes, stirring occasionally.

3. Sprinkle with the xanthan gum while whisking continuously to thicken slightly. Remove from heat.

4. In a small bowl, combine the egg yolks with the sour cream. Spoon a ladle of the hot soup into the egg/sour cream mixture to temper and thin the egg mixture, then slowly add the egg mixture to the soup, stirring constantly until well incorporated. Return soup to the heat and gently simmer, uncovered, for 10 minutes. Add salt and pepper to taste.

NOTES: This soup is actually better the second day, so feel free to make it ahead and reheat before serving. If you need to reduce sodium in your diet, you can use low sodium chicken broth in place of regular.
