Ingredients for the Best Portuguese Kale Soup
Main Ingredients:
- 1 lb kale (preferably Portuguese kale or curly kale), tough stems removed and leaves sliced thinly
- 2 tbsp olive oil (extra virgin for the best flavor)
- 1 medium onion, chopped
- 4 cloves garlic, minced
- 4 medium potatoes, peeled and diced
- 1 1/2 to 2 quarts chicken or vegetable broth (or enough to cover the ingredients)
- 2 links Portuguese chorizo or other smoked sausage (linguiça or chouriço)
- Salt and freshly ground black pepper, to taste
Optional Ingredients:
- 1 tsp paprika (smoked or sweet, depending on your taste)

- Red pepper flakes (if you want a bit of heat)
- Fresh lemon juice (for a bright finish)

How to Make the Best Portuguese Kale Soup
Step 1: Sauté the Aromatics
In a large soup pot or Dutch oven, heat the olive oil over medium heat. Add the chopped onion and sauté for 3-5 minutes until it becomes translucent and soft. Add the minced garlic and cook for another 1-2 minutes, stirring frequently, until fragrant.
Step 2: Cook the Potatoes
Next, add the diced potatoes to the pot and stir them with the onions and garlic. Allow the potatoes to cook for a few minutes, letting them absorb some of the flavors from the oil and aromatics. If you’re using wine, pour it in at this point, letting it cook down for about 2 minutes to reduce slightly.
Step 3: Add the Broth
Pour in the chicken or vegetable broth, making sure the potatoes are fully covered. Bring the mixture to a simmer, then reduce the heat to low and cook for about 15-20 minutes, or until the potatoes are tender and can easily be pierced with a fork.
Step 4: Add the Kale
Once the potatoes are cooked through, add the sliced kale to the pot. Stir the kale into the soup, allowing it to wilt and soften in the hot broth. Simmer for an additional 5-7 minutes until the kale is tender but still vibrant green.
Step 5: Prepare the Sausage
While the soup is simmering, slice the chorizo or Portuguese sausage into thin rounds. In a separate pan, heat a little olive oil over medium-high heat and sauté the sausage slices for 3-4 minutes, or until they are browned and crispy around the edges. This step helps release the sausage’s oils, adding a deeper flavor to the soup.
Step 6: Combine the Sausage and Soup
Once the sausage is ready, add it to the soup, stirring well to incorporate the flavors. Season the soup with salt, pepper, and any optional seasonings like paprika or red pepper flakes. Let everything simmer together for another 5 minutes, allowing the sausage to infuse the soup with its smoky richness.
Step 7: Adjust and Serve
Taste the soup and adjust the seasoning as needed. If you prefer a smoother texture, you can use an immersion blender to puree part of the soup before adding the sausage, creating a creamier base. If you like a bit of brightness, you can squeeze in a little fresh lemon juice to balance the richness of the sausage and potatoes.
Serve the Portuguese Kale Soup hot, with a side of crusty bread for dipping and some extra sausage slices if desired. It’s the perfect way to warm up on a cold evening or to impress guests with a taste of Portuguese comfort.
Tips for Success
- Use Quality Sausage: The chorizo or Portuguese sausage is the star of this dish, so make sure to use a good-quality sausage with a rich, smoky flavor. If you can’t find Portuguese sausage, any smoked sausage or even kielbasa can work as a substitute.
- Day-Old Kale Works Best: If possible, let your kale sit for a few hours or overnight after washing it. This will allow it to release some of its bitterness and cook down more easily in the soup.
- Customize the Heat: Add more red pepper flakes or chili oil if you like a spicier kick, or keep it mild for a more balanced flavor.
- Make It Ahead: This soup tastes even better the next day as the flavors continue to meld together. You can make it ahead and store it in the fridge for up to 3 days or freeze it for up to 3 months.
Variations of Portuguese Kale Soup
- Vegetarian Caldo Verde: Skip the sausage and use vegetable broth for a vegetarian version. You can still achieve a rich flavor by sautéing extra garlic and onion in olive oil.
- Spicy Caldo Verde: If you love heat, add more red pepper flakes or a fresh chopped chili pepper along with the garlic for an extra kick.
- Add Beans: Some variations of Caldo Verde include beans like white beans or chickpeas. These add extra protein and texture to the soup.
- Creamy Version: If you prefer a creamier soup, you can blend a portion of the soup with an immersion blender or add a splash of heavy cream toward the end of cooking.
What to Serve with Portuguese Kale Soup
- Crusty Bread: A thick slice of toasted or fresh baguette or sourdough is perfect for sopping up the flavorful broth.
- Grilled Cheese Sandwich: Pairing this soup with a gooey grilled cheese sandwich adds a comforting touch to the meal.
- Portuguese Rice: If you’re craving a heartier meal, serve the soup with a side of Portuguese rice.
- Salad: A fresh, tangy green salad dressed with lemon and olive oil complements the rich flavors of the soup.
