Spanish Lentil Soup with Chorizo: A Hearty One-Pot Meal

Spanish lentil soup with chorizo is a rustic one-pot stew of lentils, pork sausage, vegetables, and smoky paprika, served hot with bread for soaking up the broth. The recipe draws on familiar Spanish ingredients, while family and regional versions vary in their vegetables, seasonings, and thickness; this version is filling, straightforward, and made with dried lentils that cook right in the pot.

Ingredients

1 tablespoon (15 ml) olive oil
8 ounces (225 g) fresh Spanish-style cooking chorizo, casings removed if needed and cut into ½-inch (1 cm) pieces
1 medium yellow onion, about 1 cup (150 g), finely diced
2 medium carrots, about 1 cup (130 g), peeled and diced
2 celery stalks, about ¾ cup (90 g), diced
3 garlic cloves, about 1 tablespoon (15 g), minced
1 teaspoon (2 g) smoked paprika, preferably Spanish pimentón
½ teaspoon (1 g) ground cumin
1 tablespoon (16 g) tomato paste
1½ cups (300 g) dried brown or green lentils, picked over and rinsed
1 medium Yukon Gold potato, about 8 ounces (225 g), cut into ½-inch (1 cm) cubes
6 cups (1.4 L) low-sodium chicken broth or vegetable broth
1 bay leaf, about 0.1 g
½ teaspoon (3 g) fine salt, plus more to taste
¼ teaspoon (0.5 g) freshly ground black pepper, plus more to taste
1 tablespoon (15 ml) sherry vinegar or red wine vinegar
2 tablespoons (8 g) chopped fresh parsley, for serving

Instructions

Prepare the ingredients. Dice the onion, carrots, celery, and potato, mince the garlic, and rinse the lentils in a fine-mesh strainer. Check the lentils for small stones or damaged pieces as you sort them. Keep the diced potato in pieces about the same size so it softens along with the lentils.
Brown the chorizo. Heat the olive oil in a large, heavy pot or Dutch oven over medium heat. Add the fresh chorizo and cook for about 7 minutes, stirring and breaking up any larger pieces, until browned and cooked through. Because fresh chorizo is a ground-meat sausage, check a thick piece with a food thermometer; USDA FSIS gives 160°F (71°C) as the safe minimum internal temperature for ground meat. Transfer the sausage to a plate with a slotted spoon, leaving the flavorful fat in the pot. If the sausage releases very little fat, add a small splash of oil before cooking the vegetables.
Soften the vegetables. Add the onion, carrots, and celery to the pot. Cook for 8 minutes, stirring occasionally, until the onion is translucent and the vegetables begin to soften. If browned bits stick to the bottom, stir in a tablespoon of broth or water and scrape them up; they add flavor to the soup.
Bloom the seasonings. Stir in the garlic, smoked paprika, cumin, and tomato paste. Cook for 1 minute, stirring constantly, so the garlic becomes fragrant and the tomato paste darkens slightly without scorching. Smoked paprika is a defining flavor here, but it can turn bitter if left to fry in a dry pot for too long.
Build the soup. Return the chorizo to the pot and add the rinsed lentils, potato, broth, bay leaf, salt, and pepper. Stir well and bring the mixture to a gentle boil over medium-high heat, which should take about 5 minutes. Keep an eye on the pot as it heats; a hard, rolling boil can break up the potato and lentils before they are tender.
Simmer until tender. Reduce the heat to low, cover the pot with the lid slightly ajar, and simmer gently for 40 minutes. Stir every 10 to 15 minutes, scraping the bottom so lentils do not settle and catch. The soup is ready when the lentils are tender but still mostly hold their shape and the potato is soft when pierced with a fork. If the lentils are still firm, continue simmering and check every 5 minutes; older lentils can take longer. Add a little hot broth or water if the soup becomes thicker than you like.
Finish and serve. Remove the bay leaf, then let the soup stand off the heat for 5 minutes. Stir in the vinegar and taste before adding more salt or pepper, since the chorizo and broth may already be salty. Ladle into bowls and scatter parsley over the top. For a looser soup, stir in hot broth a little at a time; for a thicker, more stew-like bowl, mash a few lentils and potato cubes against the side of the pot and stir them back in.

Tips

Choose the right chorizo. Look for fresh Spanish-style cooking chorizo, rather than assuming all sausages labeled chorizo are interchangeable. Some Spanish chorizo is cured and ready to eat, while Mexican chorizo is usually fresh, softer, and seasoned differently. If you use fresh Mexican chorizo, crumble it into the pot and expect a more chile-forward flavor; drain off excess rendered fat if the soup looks greasy. Cook fresh sausage to the safe temperature in the instructions.
Use lentils that hold their shape. Brown or green dried lentils work well because they keep some texture through a long simmer. Red lentils soften much faster and tend to dissolve, so they will make a thicker, less traditional-textured pot. No soaking is needed for the brown or green lentils in this recipe.
Season at the end as well as the start. Broth and sausage vary in saltiness, and the soup concentrates as it simmers. The measured salt is a moderate starting point; taste after the vinegar goes in and adjust then. A little acid at the end brightens the rich sausage and earthy lentils, but add it gradually if your vinegar is especially sharp.
Control the texture with liquid, not extra cooking. Lentils continue absorbing broth as the soup sits. If it thickens more than you want, add hot water or broth a splash at a time. Avoid adding a large amount of cold liquid near the end, which can interrupt the simmer and make it harder to judge when the vegetables are done.

Serving Suggestions

Serve the soup in warm bowls with crusty country bread, a baguette, or toasted slices rubbed lightly with garlic. Bread is useful for catching the paprika-scented broth, while a simple green salad with a sharp vinaigrette makes a fresh contrast to the sausage and lentils. A few extra drops of sherry vinegar or a small drizzle of olive oil at the table can lift each serving without adding much preparation.

For a more substantial meal, offer a small plate of olives, roasted peppers, or sliced oranges alongside the bowls. If serving a crowd, keep the soup warm over very low heat and provide parsley, black pepper, and vinegar separately so everyone can season their own portion. The recipe is filling on its own, so extra sides can stay simple.

Variations

Make it without meat: Leave out the chorizo and cook the vegetables in 2 tablespoons (30 ml) olive oil. Add 1 teaspoon (2 g) smoked paprika and, if available, a pinch of Spanish pimentón picante or mild chile flakes for some of the sausage’s warmth. Use vegetable broth. The soup will be less rich and will not have the same cured-pork flavor, but the lentils and vegetables still make a satisfying bowl.

Use cured Spanish chorizo: If fresh cooking chorizo is unavailable, use 6 ounces (170 g) of cured Spanish chorizo, diced. Brown it briefly to release some of its paprika-seasoned oil, then set it aside while the vegetables soften. Return it to the pot with the lentils and broth. Cured sausage has a firmer, saltier bite and may release less fat, so taste carefully before adding the measured salt.

Add greens: Stir in 3 packed cups (90 g) of chopped spinach or 2 cups (120 g) of chopped kale during the last 5 to 10 minutes of simmering, just until tender. Spinach wilts quickly; kale needs a little longer. For a brighter vegetable flavor, omit the potato and add a diced red bell pepper with the onion, carrot, and celery.

Make it spicier or milder: For a hotter bowl, add ¼ teaspoon (0.5 g) crushed red pepper with the paprika, or serve chile flakes at the table. To keep the soup mild, choose a mild cooking chorizo and use sweet smoked paprika rather than hot paprika. Paprika styles vary, so check the label instead of judging only by color.

Storage and Reheating

Cool the soup promptly and refrigerate it within 2 hours of cooking in covered, shallow containers. It keeps for 3 to 4 days in the refrigerator. The lentils will absorb broth as they sit, so store the soup with its liquid and plan to loosen it with a splash of water or broth when reheating. For longer storage, freeze portions in airtight freezer-safe containers for up to 3 months; leave a little room at the top for expansion and thaw overnight in the refrigerator for the most even reheating.

Reheat a portion in a saucepan over medium-low heat, stirring occasionally and adding liquid as needed, or use a microwave-safe bowl with a loose cover, stirring partway through. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. If reheating a large batch on the stove, bring it to a steady simmer and stir so the temperature is even throughout. Avoid repeatedly cooling and reheating the entire pot; warm only the amount you plan to serve.

Frequently Asked Questions

Do I need to soak the lentils first?
No. Brown and green lentils cook directly in the broth in this recipe, so soaking is unnecessary. Rinse and sort them before adding them to the pot. If your lentils are unusually old, they may take longer to soften, so use tenderness rather than the timer alone as your final guide.

Can I use canned lentils?
Yes, but add them after the vegetables and potato are nearly tender rather than simmering them for the full 40 minutes. Use about 3 cans (15 ounces or 425 g each), drained and rinsed, and reduce the broth to about 4 cups (950 ml) to start. Simmer until the potato is tender and the canned lentils are hot, then add more broth if needed. The finished soup will have a softer texture and a shorter cooking time.

What can I use instead of Spanish chorizo?
Fresh Mexican chorizo is a practical substitute, though it is softer and often more chile-forward than Spanish cooking chorizo. Remove it from its casing if necessary, crumble it, and brown it as directed. If you cannot find either kind, use fresh Italian sausage with a pinch of smoked paprika; the flavor will be less specifically Spanish, so season to taste and do not assume the sausage has the same salt level.

Why are my lentils still firm?
They may need more time, especially if they have been stored for a long while, or the simmer may have been too gentle to cook them steadily. Keep the soup at a low, consistent simmer and check every 5 minutes. Acidic ingredients can slow softening, which is why the vinegar is added at the end. If the broth is running low, add hot water or broth while the lentils finish cooking.

Can I make the soup ahead?
Yes. The flavor settles in nicely as the soup rests, and it can be made up to 3 to 4 days ahead and kept refrigerated. Expect it to thicken overnight; stir in broth or water as it reheats and check the seasoning again, since extra liquid can dilute the salt and vinegar. Keep parsley and any other fresh garnishes separate until serving.

Is this soup meant to be thick or brothy?
It can be served either way. With the listed broth, it is a hearty soup that thickens further as it rests, but it should still spoon easily into bowls. For a more stew-like result, mash a few cooked lentils and potato pieces into the broth. For a lighter, more brothy bowl, add hot broth until it reaches the consistency you prefer.
