Skinny Portuguese Kale and Potato Soup (Caldo Verde)

My grandmother, Avó Maria, had a voice like warm honey and hands that could coax magic from the simplest ingredients. Her Caldo Verde was legendary – a vibrant green elixir that chased away winter chills and nourished the soul. I can still picture her, humming softly as she stirred the pot, the aroma of garlic and smoked sausage filling her tiny kitchen. This recipe is my attempt to capture that essence, made just a bit lighter for today’s tastes, but still brimming with all the comforting flavors of my childhood.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 30 minutes
• Total Time: 45 minutes
• Servings: 8
• Yield: 8 (1-cup) servings
• Dietary Type: Gluten-Free (check sausage ingredients)

Ingredients

• 1 lb Portuguese chourico (can use turkey chourico) or 1 lb turkey sausage (I like to use chourico dogs)
• 1 lb kale, stems removed, leaves shredded
• 1 teaspoon olive oil
• 1 onion, chopped
• 4 garlic cloves, chopped
• 6 cups fat-free chicken broth
• 4 small boiling potatoes, peeled diced into 1/4 inch pieces
• 1 pinch dried red pepper flakes
• Salt, if needed
• 1/4 teaspoon fresh ground pepper

Equipment Needed

• Large Pot
• Knife
• Cutting board
• Potato masher or immersion blender

Instructions

1. In a large pot, cook the chourico or sausage over low heat. Turn and cook until browned, about 10 minutes. This gentle cooking renders the fat and infuses the pot with flavor.
2. Remove the sausage from the pot and let it cool slightly. Once cool enough to handle, cut the sausage into slices. Set aside.
3. Carefully remove any excess fat from the pot, but be sure to leave the flavorful cooked-on bits at the bottom; these are the key to a rich and complex broth.
4. Add the olive oil to the pot, followed by the chopped onion. Cook over medium heat until the onion becomes translucent, about 5 minutes. Stir occasionally to prevent burning.
5. Add the chopped garlic and cook for 1 minute more, stirring constantly. As you stir, scrape up the browned bits from the bottom of the pan, incorporating them into the onion and garlic mixture. This process, known as deglazing, releases a depth of flavor that elevates the entire soup.
6. Add the fat-free chicken broth, diced potatoes, and black pepper to the pot. Bring the mixture to a boil, then reduce the heat and cook for 20 minutes, or until the potatoes are tender.
7. Remove the pot from the heat. Now it’s time to create the creamy texture that defines Caldo Verde. You have a few options here: You can lightly mash the potatoes with a potato masher, which will leave some chunks for added texture. Alternatively, you can use a food processor to puree a portion of the soup. My personal favorite method is to use an immersion blender directly in the pot to puree the entire mixture until smooth and creamy. Be careful to avoid splashing hot soup!
8. Add the sliced chourico or sausage and red pepper flakes to the pot. Bring the soup back to a simmer. Cook, covered, for about 4 minutes to allow the flavors to meld.
9. Add the shredded kale to the pot and bring the soup back to a simmer. Cook, partially covered, until the kale is tender and vibrant green, about 5-7 minutes.
10. Taste the soup and adjust the seasoning with salt, if needed. Keep in mind that the sausage and broth may already contain a significant amount of salt, so add it sparingly.

Expert Tips & Tricks

• Sausage Selection: The type of sausage you use significantly impacts the flavor of the soup. Authentic Portuguese chourico is ideal, but turkey chourico or even a high-quality smoked turkey sausage can be excellent substitutes. Look for sausages with a good amount of paprika and garlic.
• Kale Preparation: Be sure to remove the tough stems from the kale before shredding the leaves. Massaging the kale with a bit of olive oil before adding it to the soup can help to soften it and make it more palatable.
• Broth Enhancement: For an even richer flavor, consider using homemade chicken broth or adding a Parmesan rind to the soup while it simmers. Remove the rind before serving.
• Spice Level: Adjust the amount of red pepper flakes to your liking. If you prefer a milder soup, omit them altogether.
• Make-Ahead Tip: The soup can be made a day ahead and stored in the refrigerator. The flavors will deepen overnight. Add the kale just before serving to prevent it from becoming too soft.

Serving & Storage Suggestions

Serve the Caldo Verde hot, garnished with a drizzle of olive oil and a sprinkle of fresh black pepper, if desired. Some people also enjoy adding a squeeze of lemon juice for brightness. Crusty bread is a perfect accompaniment for soaking up the delicious broth.

Leftover soup can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze the soup in individual portions for up to 2 months. To reheat, thaw the soup in the refrigerator overnight and then gently warm it on the stovetop or in the microwave. If the soup has thickened during storage, add a little broth or water to thin it out.

Variations & Substitutions

• Vegan Caldo Verde: Omit the sausage and use vegetable broth instead of chicken broth. Consider adding smoked paprika to mimic the smoky flavor of the sausage.
• Different Greens: While kale is traditional, you can experiment with other hearty greens such as collard greens or turnip greens. Adjust the cooking time as needed.
• Bean Addition: Add a can of drained and rinsed cannellini beans or great northern beans for added protein and fiber.
• Sweet Potato Variation: Substitute half of the potatoes with sweet potatoes for a slightly sweeter and more vibrant flavor.
• Spicy Caldo Verde: Add a chopped jalapeno pepper or a dash of hot sauce for an extra kick.

FAQs (Frequently Asked Questions)

Q: Can I use frozen kale in this recipe?
A: Yes, frozen kale can be used, but be sure to thaw it completely and squeeze out any excess water before adding it to the soup.

Q: What is chourico, and where can I find it?
A: Chourico is a Portuguese smoked sausage, similar to chorizo but often spicier. You can find it at Portuguese markets, specialty food stores, or sometimes in the international section of well-stocked supermarkets.

Q: How can I make this soup even healthier?
A: To reduce the sodium content, use low-sodium chicken broth and be mindful of the amount of salt you add. You can also increase the amount of kale and reduce the amount of sausage.

Q: Can I use different types of potatoes?
A: Boiling potatoes, such as Yukon Gold or red potatoes, are ideal for this soup because they hold their shape well. Russet potatoes will work, but they may break down more during cooking.

Q: Is it necessary to puree the soup?
A: No, pureeing the soup is optional. If you prefer a chunkier soup, you can simply mash some of the potatoes with a potato masher.
