Keto Caldo Verde – Chorizo & Kale Soup

Keto Caldo Verde

Jump to Recipe

Caldo Verde is a traditional soup from northern Portugal also known as green soup. It is typically made with kale, potatoes and smoked sausage. In our Keto Caldo Verde we keep almost all of the ingredients the same, but we swap the potatoes for cauliflower. This soup is very easy to make and is the perfect recipe for cold and rainy days.  


This recipe is typically made with a Portuguese sausage called linguiça. If you are unable to find this, any cured lightly smoked sausage will do. We use dried Spanish style chorizo in this recipe, however andouille sausage will also work!


To make this recipe low carb, we swap out potatoes for cauliflower. Boil the cauliflower in the soup until soft and blend to make the creamy soup base. You can also leave the cauliflower as florets in this recipe, however we find that the texture is nicer when puréed.


For this Keto Caldo Verde we use kale in the recipe. However, any dark leafy greens such as swiss chard or collard greens would work nicely! If using kale, we recommend removing the tough stem and massaging the kale before adding it to this soup. This will make sure the greens are nice and soft.
