Caldo verde is the soup you find in every corner of Portugal, from family kitchens to late-night tascas. Pureed potato gives it a velvety body without any cream, and very finely shredded greens go in at the last minute so they stay bright and squeaky rather than dull.
The greens matter: traditional caldo verde uses couve, a dark Portuguese kale, and the closest everyday swaps are collard greens or curly kale. Slice them as thinly as you can — the fine ribbons are part of the texture, not a detail.
This version keeps things vegetarian with smoked paprika and a smoked plant-based sausage for the smoky depth that chouriço usually brings. Skip the sausage entirely and double the paprika if you prefer, and finish each bowl with a generous drizzle of good olive oil and plenty of black pepper.

Ingredients
- 700 g floury potatoes, peeled and cut into chunks
- 1 large onion, chopped
- 4 garlic cloves, roughly chopped
- 1.2 litres vegetable stock
- 1 tsp fine salt, plus more to taste
- 1/2 tsp black pepper
- 1 tsp smoked paprika
- 200 g collard greens or curly kale, tough stems removed
- 150 g smoked vegetarian sausage or smoked tofu, sliced (optional)
- 4 tbsp extra virgin olive oil, plus more to serve
- Fresh crusty bread or cornbread, to serve
Instructions
- Warm 2 tbsp of the olive oil in a large pot over medium heat and cook the onion for 6-7 minutes until soft and translucent.
- Add the garlic and smoked paprika and cook for 1 minute until fragrant.
- Add the potatoes, stock, 1 tsp salt and the pepper. Bring to a boil, then reduce the heat and simmer for 18-20 minutes until the potatoes fall apart when pressed.
- While the potatoes cook, stack the greens, roll them tightly and slice as thinly as you can into fine ribbons.
- If using smoked sausage or tofu, brown it in a small pan with the remaining 2 tbsp olive oil and set aside.
- Blend the soup until completely smooth with a stick blender, or transfer to a jug blender in batches. It should be the consistency of thin cream; loosen with a splash of stock or water if needed.
- Return the soup to a gentle simmer, taste for salt and stir in the shredded greens. Cook for 4-5 minutes only — the greens should stay vivid green and slightly firm.
- Stir the smoked sausage or tofu through, ladle into bowls and finish each with a generous drizzle of olive oil and a grind of black pepper.
- Serve with crusty bread or a slice of cornbread for dipping.
Cook’s tips
- Use floury potatoes such as Maris Piper or Russet — waxy ones give a gluey texture rather than a silky one.
- Slice the greens as finely as you can. Thick ribbons stay tough and taste bitter.
- Add the greens at the very end and do not overcook them; their colour is the whole point.
- Blend the soup thoroughly. Any lumps of potato make it feel like a stew rather than a velvet soup.
- The olive oil finish is not garnish — a fruity Portuguese oil transforms the bowl.
Substitutions
- Spring greens, cavolo nero or Savoy cabbage can all stand in for the collard greens.
- For a fully plant-based soup, skip the sausage and add an extra teaspoon of smoked paprika plus a pinch of smoked salt.
- A knob of butter stirred in at the end gives an even richer result if you are not keeping it dairy-free.
Storage & reheating
Keeps in the fridge for 4 days. The colour dulls as it sits, so reheat gently and stir in a handful of freshly sliced greens to brighten it. It does not freeze well because the potatoes turn grainy.
FAQ
What greens are used in caldo verde?
Traditionally couve, a dark Portuguese kale. Collard greens are the closest substitute, with curly kale or cavolo nero as good everyday alternatives.
Is caldo verde usually made with sausage?
Yes, chouriço is traditional and gives the soup its smoky note. This version uses smoked paprika and optional smoked plant-based sausage so it stays vegetarian.
Why does my caldo verde taste bland?
It almost always needs more salt and more olive oil. Season the potatoes properly and finish the bowl with a generous drizzle of a fruity extra virgin oil.
