This Low Carb Kale Sausage Soup is one of our favorite low-carb soups, with hearty chunks of sausage and kale in a creamy broth.
You might not know this, but sausage and kale go really well together, and when you add them to a creamy tomato broth, it becomes a soul-warming soup that you’ll want to eat all the time.
A soup like this, with spicy Italian sausage and kale, is called Zuppa Tuscano in Italy, although that version always includes potatoes or white beans. I still like to think of this as a delicious Italian soup.
It’s really one of my favorite soups and I’m thrilled that it can be made low carb. This version obviously leaves out the potato and beans, but it also cuts down on onion and tomato paste, which can add additional unnecessary carbs.
How to Make Kale Sausage Soup
The first thing you’ll need to do for this recipe is brown the sausage and the bacon.
I use spicy ground sausage because it has a lot of flavor, but you can substitute with any sausage you want. Just make sure it’s not highly processed and containing extra hidden carbs in the form of sugars.
While it’s not necessary (and it’s not a step I included in the recipe below to keep it super simple), I think it adds an extra depth of flavor to sauté the kale in the bacon drippings before adding it to the soup. But you can skip this step, if you want.
Next saute the onion and garlic, then add the water, chicken bouillon cubes and seasonings. Let this all meld together. Then add the sausage, bacon, tomatoes and kale to the pot and let it all simmer for about 10-15 minutes.
The last thing you’ll do is add the cream to the soup. Just heat it through, don’t boil it once the cream has been added.
This soup isn’t thick. If you want to thicken it up a little bit, you can add the Parmesan cheese to the soup and stir it in. I prefer it not thick, and I think the nice dusting of Parmesan cheese on top is best.
Another way to thicken the soup is by adding xanthan gum. About 1/4 tsp is all you need to give the soup a thicker, silky broth.
Can Kale Sausage Soup Be Frozen?
This soup doesn’t freeze well due to the addition of the cream. If you want to freeze some of the soup, I would suggest reserving what you wish to freeze before adding the cream. Freezing it without the cream will allow the reheating of the soup without clumpy broken cream.
Reheat the frozen soup on the stovetop and add the cream once the soup has been fully reheated.
