Ingredients
Vegetables
- 750 g baby potatoes (1.65 lb), peeled and chopped
- 1 regular onion, peeled and chopped
- 2 cloves of garlic, peeled and chopped
- 150 g cavolo nero (5 oz), tough stems removed and shredded
- 100 g kale (3 oz), tough stems removed and shredded
Liquids & Oils
- 3 tablespoons olive oil
- 1 litre vegetable stock (4 cups)
Seasonings
- 1 teaspoon sea salt
- ¼ teaspoon ground black pepper
Instructions
- Heat the oil and sauté onion: Warm the olive oil in a large pan over medium heat, then add the peeled and chopped onion. Fry it gently until it turns golden and fragrant, about 5-7 minutes, stirring occasionally.
- Add garlic and potatoes: Stir in the peeled and chopped garlic and potatoes to the pan. Pour in the vegetable stock, ensuring the potatoes are submerged. Bring to a boil, then reduce to a simmer and cook until the potatoes become tender, about 15-20 minutes.
- Prepare the greens: While the potatoes cook, remove the tough central stems from the cavolo nero and kale leaves. Shred the leaves finely into thin ribbons using a sharp knife or kitchen scissors.
- Blend the soup: Once the potatoes are soft, use a hand blender to blend the soup directly in the pan until it reaches a smooth and creamy texture. Be careful not to overblend if you prefer some texture.
- Add greens and season: Stir in the shredded cavolo nero and kale leaves, along with the sea salt and black pepper. Return the pan to medium-low heat and cook for another 2-3 minutes to allow the greens to soften gently.
- Serve hot: Ladle the caldo verde into bowls and serve immediately. Optionally, drizzle with extra olive oil and sprinkle additional black pepper for enhanced flavor.
Notes
- Using baby potatoes helps the soup achieve a creamier texture when blended.
- If cavolo nero or kale are not available, you can substitute with collard greens or Swiss chard.
- For a heartier version, traditional Portuguese chorizo slices can be added, but this recipe is vegetarian.
- Blending the soup creates a silky texture, but you can leave it chunky if preferred.
- Adjust seasoning at the end to taste; some prefer more black pepper or a splash of lemon juice for brightness.
