Keto Ukrainian Green Borscht (Spinach Soup)



Jump to Recipe

At home we call this recipe Spinach Soup. It is traditionally known as Sorrel Soup, but sorrel can be hard to find here in North America. This Keto Ukrainian Green Borscht is a low carb adaptation of my mother-in-laws recipe. The only difference is we omit the potatoes. This is our favorite soup as it’s not only delicious but very healthy and easy to digest. 


For our Keto Ukrainian Green Borscht we have made a few substitutes to the vegetables used. None of the substitutions affect the flavor! My mother-in-law makes this recipe with potatoes and sweet potatoes. Of course we need to omit those on a keto diet, so I have added zucchini and optional cauliflower florets. I personally leave out the cauliflower florets because I find that the soup is filling without it. However, if you want a more hearty soup, cauliflower is a great option. 


My mother-in-law has always made this soup with just water and it turns out very flavorful. I do however, like to use chicken or vegetable broth as it slightly adds more flavor to the soup. If using broth, I find that it doesn’t need to simmer for as long to allow the flavors to come together. 

Spinach soup is a very simple recipe. When I first made this soup (I was probably only 18 or 19) I was underwhelmed with the flavor. I couldn’t figure out what I was doing wrong. If you’re having this issue, here are a few steps that I suggest: 

  1. Add more salt! Of course,  salt always adds to the flavor of dishes. Taste your soup and adjust the salt as needed. I usually start with 1 tsp and adjust throughout cooking as needed.
  2. Taste with sour cream. Take a small portion of the soup into a bowl to test its flavor. Add a small amount of sour cream with the soup and test the flavor. 
  3. More time. Allow for the soup to simmer longer to allow the flavors to come together. 
  4. Add more dill.  It could be because I am married to a Ukrainian, but I love dill. I will usually add way more than what a recipe calls for. If your soup is lacking flavor, try adding more dill!

Sour Cream 

It may seem odd to add sour cream into a soup. Even classic borscht should be eaten with a dollop of sour cream. Trust us, this soups needs to be eaten with sour cream. The flavors really come together once the sourness is added. It pairs perfectly with the lemon and spinach. It also turns the soup this amazing bright color!

Hard Boiled Egg 

The hard boiled egg is optional, but it does pair nicely with the flavors of the soup. Not only that, but it makes this a more filling and complete meal.
