Types of Food in Portugal: Caldo Verde Recipe

Portuguese food ranges from seafood and grilled fish to hearty soups, rice dishes, sausages, and custard pastries; caldo verde is one of the country’s best-known soups. This northern Portuguese classic combines potatoes, thinly sliced greens, olive oil, and often chouriço, making a satisfying bowl that is simple to prepare at home. Recipes vary by region and household, so this version keeps the potato-and-greens base while offering practical substitutions for ingredients that may be hard to find.

Ingredients

2 tablespoons (30 ml) extra-virgin olive oil, plus more for serving
1 medium yellow onion, finely chopped, about 1 cup (150 g)
3 garlic cloves, minced, about 1 tablespoon (9 g)
2 pounds (900 g) Yukon Gold or floury potatoes, peeled and cut into 1-inch (2.5 cm) pieces
6 cups (1.42 L) low-sodium chicken or vegetable broth
1 cup (240 ml) water
1 bay leaf, about 0.2 g
1 teaspoon (5 g) fine salt, plus more to taste
¼ teaspoon (0.5 g) freshly ground black pepper
8 ounces (225 g) collard greens or kale, stems removed and leaves sliced very thinly
6 ounces (170 g) Portuguese chouriço, sliced into thin rounds; use ready-to-eat cured sausage or see the substitution in Tips

Instructions

Prepare the ingredients, about 20 minutes. Peel and cut the potatoes into evenly sized pieces so they soften at the same rate. Chop the onion and garlic, remove tough stems from the greens, and slice the leaves into very narrow ribbons. Thinly slice the chouriço. Keep the greens separate from the potatoes; they go into the pot near the end so they stay green and tender.
Brown the chouriço. Set a small skillet over medium heat and cook the slices for 6 to 8 minutes, turning once, until lightly browned and some of their fat has rendered. Transfer them to a plate. If you are using raw, uncured pork sausage instead of ready-to-eat chouriço, cook it through to the USDA FSIS safe minimum internal temperature of 160°F (71°C), checking the center with a food thermometer. Set the skillet aside; you can use a spoonful of the rendered fat to flavor the soup if you like.
Soften the aromatics. Heat the olive oil in a large, heavy pot over medium heat. Add the onion and cook for about 5 minutes, stirring occasionally, until soft and translucent but not browned. Stir in the garlic and cook for 1 minute. If using a little rendered sausage fat, reduce the olive oil slightly so the soup does not become greasy.
Simmer the potatoes, about 25 minutes. Add the potatoes, broth, water, bay leaf, salt, and pepper. Bring the liquid to a gentle boil, which usually takes about 5 minutes, then lower the heat and simmer uncovered for about 20 minutes. Stir once or twice. The potatoes are ready when a fork slides through the largest piece easily; if they are still firm, give them a few more minutes.
Make the potato base. Remove and discard the bay leaf. Use an immersion blender to purée the soup until mostly smooth, leaving a little texture if you prefer. Alternatively, mash the potatoes directly in the pot with a potato masher. If using a countertop blender, work in batches, do not fill it more than halfway with hot liquid, and hold the lid in place with a folded towel. Return the purée to the pot if needed.
Cook the greens, about 5 minutes. Bring the soup back to a gentle simmer and stir in the sliced greens. Cook uncovered for about 5 minutes, until they have softened but remain bright. Very thick collard ribbons may need a few extra minutes. If the soup seems too thick, add hot water a little at a time; if it looks thin, simmer it briefly before adding the greens.
Finish and serve. Stir in the browned chouriço, or arrange the slices on top of each serving. Taste and adjust the salt and pepper. Ladle into warm bowls and finish with a small drizzle of olive oil. The cooking time is about 40 minutes, including the time to soften the onion, bring the soup to a simmer, cook the potatoes and greens, and finish the pot.

Tips

Slice the greens finely. Traditional couve-galega, a Portuguese leafy cabbage, is not easy to find in many grocery stores. Collard greens are a close practical substitute and hold their shape well; curly kale works too, with a slightly firmer, more pronounced leafy texture. Remove thick ribs and make narrow ribbons so the greens cook quickly and are easy to eat with a spoon.
Choose the sausage to suit your pantry. Portuguese chouriço has its own seasoning and is not identical to Spanish chorizo, which is often smokier or hotter. Spanish cured chorizo or another fully cooked smoked sausage can stand in, though the flavor will shift. For a meat-free pot, leave it out and use vegetable broth; the soup will still have a savory potato-and-greens character.
Keep the simmer gentle. A hard boil can break the potatoes apart before they soften evenly and may make a blended soup feel gluey. Once the broth reaches a boil, lower the heat. Blend only until the base is smooth enough for your taste; a few small potato pieces give it a more rustic texture.
Season in stages. Broths and cured sausages can both be salty. Start with the measured salt, then taste after the potatoes are cooked and again after the sausage is added. A final drizzle of good olive oil adds aroma, while extra salt cannot be taken back out.

Serving Suggestions

Serve caldo verde as a first course or make it the center of a light supper with crusty bread for dipping. In Portugal, bread is a natural companion to soup, and a simple loaf is especially useful for catching the olive oil and broth at the bottom of the bowl. For a fuller meal, offer a small plate of olives, a salad dressed with vinegar, or grilled vegetables alongside it. Keep the accompaniments straightforward: the soup already brings starch, greens, and, when included, sausage.

This bowl also gives a useful glimpse of the range of Portuguese cooking. Seafood is prominent along the coast, with grilled sardines and seafood rice among familiar dishes; inland meals often feature pork, beans, and slow-cooked stews. Soups such as caldo verde are everyday comfort food, while pastéis de nata are famous custard tarts served as a snack or dessert. These are broad patterns rather than strict rules—what people cook depends on the region, season, and household.

Variations

Make it vegetarian: Use vegetable broth and omit the chouriço. To add a savory finish without sausage, drizzle each bowl with olive oil and offer black pepper at the table. The result is less smoky than the sausage version but still has the characteristic silky potato base and ribbons of greens.

Try a different green: Portuguese couve-galega is the traditional choice, but collards and kale are easier to source in many places. Swiss chard can also work; add its sliced stems with the onion and put the leaves in near the end. Spinach wilts much faster and has a softer texture, so stir it in only for the final minute or two.

Adjust the texture: For a thicker soup, use the full amount of potatoes and blend the base thoroughly. For a looser bowl, add extra hot broth or water after blending. Some versions leave more potato pieces intact, while others are nearly smooth; neither texture is required for a good home pot. You can also serve the sausage separately so each person chooses how much to add.

Storage and Reheating

Refrigerate the soup within 2 hours of cooking, preferably in shallow, covered containers, and keep it for 3 to 4 days. If you expect leftovers, you can store the chouriço separately and add it to individual bowls; this helps the sausage retain more of its browned texture. The greens soften as they sit, but the soup remains suitable for reheating within the recommended storage time.

Warm portions gently in a saucepan over medium-low heat, stirring often and adding a splash of water or broth if the potato base has thickened. Reheat leftovers to 165°F (74°C), checking with a food thermometer. You can also microwave a covered portion, stirring halfway through and checking the temperature in more than one spot. Freeze cooled soup in airtight containers for up to 2 months for best quality; leave a little space at the top, thaw in the refrigerator, then reheat to 165°F (74°C). The texture may be slightly less smooth after freezing, so stir well or briefly blend it again.

Frequently Asked Questions

What kinds of food is Portugal known for?
Portugal is known for seafood, grilled fish, hearty soups, pork dishes, rice dishes, and pastries. Examples include grilled sardines, seafood rice, caldo verde, and pastéis de nata. Regional cooking varies: coastal menus often make use of fish and shellfish, while inland dishes may lean more heavily on pork, beans, and local vegetables.

Is caldo verde always made with chouriço?
No. Chouriço is a common topping or addition, but recipes differ, and it can be left out. This recipe keeps the sausage optional so the soup can be made vegetarian. If you omit it, use vegetable broth for a meat-free version and taste carefully for seasoning before serving.

Can I make caldo verde without a blender?
Yes. A potato masher works well: mash the cooked potatoes in the pot until the broth thickens, leaving some pieces intact. The soup will be more rustic and less uniform than a blended version, but the greens and sausage still fit naturally into that texture. Avoid vigorous whisking, which can make potatoes sticky.

Which potatoes are best for this soup?
Yukon Gold potatoes give a creamy base and are easy to find. Floury potatoes, such as russets, also blend smoothly but may produce a thicker soup, so keep a little extra hot broth or water nearby. Cut the potatoes into similar-sized pieces and cook until fully tender before mashing or blending.

Can I prepare the soup ahead of time?
Yes. Make the soup through the potato-and-greens stage, cool it promptly, and refrigerate it in covered containers. For the freshest texture, brown and add the sausage when reheating, or keep it separate and garnish each bowl. Reheat the soup to 165°F (74°C), adding a little broth or water if it has thickened in the refrigerator.
