Caldo Verde – Portuguese Kale and Chorizo Soup
Portugal's national soup: silky potato and kale broth with slices of smoky chouriço — humble, nourishing and deeply comforting.
About This Recipe
Caldo Verde — 'green broth' — is Portugal's most beloved soup and one of the country's national dishes, served at every celebration from weddings to football matches. It is a beautifully simple soup: a silky-smooth potato base seasoned with olive oil and garlic, into which very finely shredded kale (couve galega) is stirred at the end, and slices of chouriço (Portuguese smoked sausage) are floated on top. The character of the soup lies in its contrasts: the creamy, neutral potato broth against the iron-rich, slightly bitter kale; the mild background and the intensely smoky, paprika-spiked sausage. The kale must be cut into the finest possible ribbons — traditional cooks use a dedicated mandoline-like cutter, the cortador de couve — as the ultra-fine shreds cook almost instantly in the hot broth, staying bright green and slightly toothsome rather than going grey and limp. Caldo Verde originated in the Minho region of northern Portugal and has been made for centuries. It is intrinsically linked to the corn bread (broa de milho) that traditionally accompanies it, used to soak up the last drops of olive oil-slicked broth.

Cook the base

Fry the chorizo
In a small pan, fry the chouriço slices in a little olive oil for 2 minutes until lightly coloured.

Add kale and serve
Bring the soup back to a boil. Add the very finely shredded kale and cook for exactly 2 minutes — no more. Ladle into bowls, float chouriço slices on top, drizzle with the remaining olive oil.
The kale must be cut into the thinnest possible ribbons — this is what distinguishes caldo verde from other kale soups.
Pro Tips
- →
The finer the kale shreds, the better — aim for 1–2mm wide ribbons, not rough chops.
- →
Use a good, fruity Portuguese olive oil — it's a main flavour in the finished soup.
- →
Don't overcook the kale: 2 minutes keeps it bright green and slightly al dente.
Variations
- •
Vegetarian version: omit chouriço, add smoked paprika to compensate
- •
Heartier version: add white beans with the potatoes
- •
Lighter version: replace half the potatoes with sweet potato
Storage
Refrigerate for up to 3 days. Add the kale fresh when reheating — don't store with kale already in, as it loses colour.
History & Origin
Caldo Verde originated in the Minho region of northern Portugal, where the local kale variety couve galega has been cultivated for centuries. The soup became associated with Portuguese identity through its ubiquity at communal celebrations. António de Oliveira Salazar, Portugal's long-serving prime minister, reportedly named it his favourite soup, which helped cement its status as the national dish.
Frequently Asked Questions
What is the best kale to use?
Traditional caldo verde uses couve galega, a Portuguese variety of flat-leaf kale unavailable outside Portugal. Cavolo nero (Tuscan black kale) is the closest substitute and gives excellent results. Curly kale also works but needs even finer shredding. Savoy cabbage is sometimes used in simpler versions.
