Portuguese Kale and Chorizo Soup, Made for Weeknights

Portuguese kale and chorizo soup is a hearty, one-pot soup of potatoes, leafy greens, and smoky sausage, inspired by Portugal’s caldo verde. This version makes a satisfying meal with readily available ingredients; Portuguese chouriço is traditional in many versions, while Spanish chorizo or another smoked sausage gives the soup a slightly different but delicious character.

Ingredients

2 tablespoons (30 ml) extra-virgin olive oil
8 ounces (225 g), about 1 1/2 cups sliced, Portuguese chouriço, or smoked Spanish chorizo, cut into thin half-moons; for raw pork chorizo, remove the casing and crumble it
1 medium yellow onion, about 1 cup diced (150 g)
3 garlic cloves, finely chopped, about 1 tablespoon (9 g)
1 teaspoon (2 g) sweet paprika, optional
1 bay leaf (about 0.2 g)
2 pounds (900 g) Yukon Gold or russet potatoes, peeled and cut into 1-inch cubes, about 5 cups
7 cups (1.65 L) low-sodium chicken broth or vegetable broth
1 teaspoon (6 g) fine salt, plus more to taste
1/2 teaspoon (1 g) freshly ground black pepper
8 packed cups thinly sliced kale, about 8 ounces (225 g), tough stems removed
1 tablespoon (15 ml) red wine vinegar or lemon juice, plus more to taste

Instructions

Prepare the ingredients. Peel and cube the potatoes, dice the onion, chop the garlic, and slice the kale into thin ribbons. If using kale with thick ribs, strip the leaves from the stems before slicing; the stems stay tough longer than the leaves. Keep the potato cubes fairly even so they soften at the same time.
Brown the sausage. Set a large, heavy soup pot or Dutch oven over medium heat and add the olive oil. Add the sliced cooked chouriço and cook for about 6 minutes, turning occasionally, until it is lightly browned and has released some of its paprika-colored fat. If using raw pork chorizo, crumble it into the pot and cook it through instead; check the center with a food thermometer and reach 160°F (71°C), the USDA FSIS safe minimum for ground meat. Transfer the sausage to a plate, leaving the flavorful oil in the pot.
Soften the aromatics. Add the onion to the pot and cook for 5 minutes, stirring and scraping up browned bits, until it is soft and translucent but not deeply browned. Stir in the garlic and paprika and cook for 1 minute, just until fragrant. Garlic can turn bitter if it scorches, so keep it moving and lower the heat if the pot is too hot.
Simmer the potatoes. Add the bay leaf, potatoes, broth, salt, and black pepper. Bring the liquid to a boil, then lower the heat to maintain a gentle simmer. Cover the pot partially and cook for 22 minutes, or until a knife slides easily into a potato cube. Stir once or twice during cooking; if the broth boils hard, the potatoes can break apart unevenly and the liquid may reduce too quickly.
Thicken the base. Remove the bay leaf. Use a potato masher to crush some of the potatoes directly in the pot, leaving plenty of pieces intact. About a third of the potatoes is a good starting point: they release enough starch to give the broth body while keeping the soup pleasantly chunky. For a smoother base, mash more; avoid blending hot soup in a sealed blender.
Add the kale and sausage. Stir in the kale and browned sausage. Simmer uncovered for 8 minutes, stirring once or twice, until the greens are tender but still green. If the pot looks crowded at first, add the kale in batches; it wilts quickly. The soup should be thick but ladleable. Stir in a little hot water or broth if it becomes thicker than you like.
Season and serve. Stir in the vinegar or lemon juice, then taste the broth. Add more salt, pepper, or acid as needed; sausage and broth vary in saltiness, so make the final adjustment at the end. Ladle into warm bowls and serve while the kale is tender and the potatoes are hot.

Tips

Choose the sausage with the flavor in mind. Portuguese chouriço is a cured, smoky pork sausage often used in caldo verde. It can be harder to find outside Portuguese groceries, so smoked Spanish chorizo is a practical substitute, though its paprika and garlic notes may be more pronounced. Fresh Mexican-style chorizo is uncooked and softer; remove its casing, crumble it, and cook it fully before adding the broth.
Slice the greens finely. Thin ribbons are easier to eat and soften quickly in the soup. Curly kale works well, as does lacinato kale. If using collard greens, remove the central ribs and allow a few extra minutes of simmering because collards are sturdier.
Control the texture with the potatoes. Yukon Gold potatoes hold their shape and make a creamy, lightly thickened broth when partially mashed. Russets break down more readily and create a thicker base. Mash gradually rather than crushing every piece at once; you can always make the soup smoother, but you cannot restore the chunks.
Season after the sausage and broth are in. Chouriço and packaged broth can both be salty. Start with the listed salt, then taste before adding more. A spoonful of vinegar or lemon at the end brightens the soup without making it taste distinctly sour.

Serving Suggestions

Serve the soup hot as a main course, with crusty bread for dipping into the paprika-rich broth. A simple green salad with a sharp vinaigrette makes a fresh contrast to the potatoes and sausage. You can also offer extra olive oil, black pepper, and vinegar at the table so everyone can adjust their bowl. For a more substantial spread, add a plate of olives or roasted vegetables, but the soup is filling enough to stand on its own.

If serving guests, keep the pot warm over very low heat rather than letting it boil; prolonged boiling can make the kale dull and break the potatoes down further. The soup thickens as it sits, so have a little hot broth or water ready to loosen individual portions. Serve bread separately so it stays crisp until dipped.

Variations

Make it vegetarian: Leave out the sausage and use vegetable broth. For smoky depth, add 1 teaspoon (5 ml) smoked paprika with the garlic and sauté 8 ounces (225 g) sliced mushrooms with the onion until browned. The result will not have the same cured-pork flavor, but it remains savory and satisfying.

Use beans: Stir in one drained 15-ounce (425 g) can of white beans during the final 8 minutes, along with the kale. Beans make the soup heartier and soften the contrast between greens and sausage. If you use them, reduce the potatoes by about 1 cup (150 g) if you prefer a looser soup.

Swap the greens: Collards, Swiss chard, or mustard greens can stand in for kale. Chard cooks quickly, so add it for the final 4 to 5 minutes; collards may need 10 to 12 minutes, depending on how finely they are cut. Mustard greens have a peppery edge, so taste before adding extra black pepper.

Adjust the heat: Use hot chouriço or spicy chorizo, or add a pinch of red pepper flakes with the garlic. For mild soup, choose a mild sausage and leave out the flakes. Smoked paprika is optional because the sausage already brings smoky flavor; use sweet paprika instead if you want color without extra smoke.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in shallow, covered containers. The soup keeps for 3 to 4 days in the refrigerator. It will thicken as the potatoes absorb broth, and the kale will soften further, but the flavor remains good. Store bread separately so it does not become soggy.

Reheat only the portion you plan to eat in a saucepan over medium-low heat, stirring occasionally and adding a splash of broth or water if needed. Heat leftovers to 165°F (74°C), checking with a food thermometer. In a microwave, cover the bowl loosely, heat in short intervals, and stir between intervals so the middle warms evenly; confirm it reaches 165°F (74°C). Avoid repeatedly cooling and reheating the whole pot.

For longer storage, freeze cooled soup in freezer-safe containers for up to 2 months for best quality. Leave a little space at the top for expansion. Potatoes may become softer after thawing, so stir gently as the soup reheats. Thaw overnight in the refrigerator when possible, then reheat to 165°F (74°C). Do not leave cooked soup at room temperature for more than 2 hours.

Frequently Asked Questions

Is this the same as caldo verde? It is a Portuguese-style kale and potato soup inspired by caldo verde, a well-known Portuguese dish commonly made with finely sliced greens, potatoes, and chouriço. Recipes differ between households and regions: some purée much of the potato base, while others leave it chunkier, and the type and amount of sausage can vary. This recipe keeps some potato pieces intact for a rustic texture.

Can I use Spanish chorizo instead of Portuguese chouriço? Yes. Smoked Spanish chorizo is an accessible substitute and works well in the pot, although its seasoning may be more paprika-forward than Portuguese chouriço. If your sausage is already cooked or cured, brown it briefly as directed. If you are using raw ground pork chorizo, cook it separately in the pot until it reaches 160°F (71°C) before adding the broth.

Can I make the soup ahead? Yes. Make it up to 3 days ahead and refrigerate it promptly. The potatoes will continue to absorb broth, and the greens will soften, so add broth or water while reheating to restore a spoonable consistency. For the freshest green color and texture, you can cook the soup base ahead and stir in the kale shortly before serving.

What if I do not have a potato masher? Use the back of a sturdy spoon or a fork to press some of the potatoes against the side of the pot. You can also scoop out 1 to 2 cups (240 to 480 ml) of potatoes with broth, mash them in a bowl, and return them to the pot. Leave the soup partly chunky for its characteristic rustic feel.

Why is my soup too thick or too thin? Potatoes vary in starchiness, and the amount of liquid lost during simmering can change with the pot and heat level. If it is too thick, stir in hot broth or water a little at a time. If it is too thin, simmer it uncovered for a few minutes or mash a few more potato pieces; avoid adding flour, which can make the broth pasty.

Can I use frozen kale? Yes. Add frozen kale straight to the simmering soup, breaking it apart as it thaws, and cook until hot and tender. It may release extra water and have a softer texture than fresh kale, so simmer uncovered for a few extra minutes if the broth seems diluted. Taste again before serving because the final seasoning may need adjustment.
