Dominican Mondongo Soup with Tender Tripe and Vegetables

Dominican mondongo is a hearty tripe soup simmered with vegetables, herbs, and a bright citrus finish. Recipes vary by household and region, but this stovetop version builds a savory broth around tender tripe, potatoes, auyama, and green plantain.

Ingredients

2 lb (900 g) beef tripe, preferably honeycomb or blanket tripe, trimmed of any excess tough membrane
10 cups (2.4 L) water, for blanching the tripe
8 cups (1.9 L) unsalted beef broth, or water for a lighter, less beefy soup
2 tbsp (30 ml) neutral oil or olive oil
1 medium yellow onion, finely chopped, about 1 cup (150 g)
1 medium green bell pepper, finely chopped, about 1 cup (150 g)
4 garlic cloves, minced, about 12 g
2 tbsp (30 g) tomato paste
1 tsp (1 g) dried oregano
1 bay leaf
1½ tsp (9 g) fine salt, plus more to taste
½ tsp (1 g) ground black pepper
2 medium carrots, peeled and cut into ½-inch pieces, about 2 cups (250 g)
2 medium potatoes, peeled and cut into ¾-inch cubes, about 2 cups (300 g)
2 cups (300 g) peeled, seeded auyama, also called calabaza or West Indian pumpkin, cut into 1-inch chunks
1 medium green plantain, peeled and cut into ½-inch rounds, about 1 cup (180 g); optional but traditional in some versions
¼ cup (40 g) Dominican alcaparrado or pitted green olives, drained; optional
3 tbsp (45 ml) sour orange juice, or 2 tbsp (30 ml) orange juice plus 1 tbsp (15 ml) lime juice
½ cup (15 g) chopped fresh cilantro, including tender stems

Instructions

Prepare the tripe. Cut the tripe into pieces about 1 inch (2.5 cm) wide so they cook evenly and are easy to eat. If the package gives specific cleaning directions, follow them; avoid splashing raw tripe or its juices around the sink. Put the 10 cups (2.4 L) water in a large pot and bring it to a boil. Add the tripe and boil for 10 minutes. Drain it in a colander, discard the blanching water, and wash the pot with hot, soapy water before using it again. This brief blanch helps remove a strong aroma without replacing the long simmer needed to soften the tripe.
Simmer until tender. Return the blanched tripe to the clean pot and add the 8 cups (1.9 L) broth. Bring it just to a boil, then lower the heat so the liquid simmers gently. Partially cover and cook for 1 hour 45 minutes, stirring once or twice. Keep the tripe submerged; add a little hot water if the liquid drops substantially. Check a thick piece with a food thermometer: USDA FSIS lists 160°F (71°C) as the safe minimum for organ meats such as tripe. The tripe should be safe before it is fully tender, so continue simmering if it still feels rubbery when pierced with a fork.
Chop and build the flavor base. While the tripe simmers, prepare the onion, pepper, garlic, carrots, potatoes, auyama, and plantain. Heat the oil in a skillet over medium heat. Add the onion and bell pepper and cook for about 5 minutes, stirring, until softened. Stir in the garlic and tomato paste and cook for 1 minute, then add the oregano, bay leaf, salt, and black pepper. Cook for another 1 minute, stirring so the garlic does not scorch. Set the sofrito aside until the tripe is tender.
Finish the soup. Once the tripe is tender, stir the sofrito into the pot. Add the carrots, potatoes, auyama, plantain if using, and alcaparrado or olives if using. Bring the soup back to a gentle simmer, partially cover, and cook for 35 minutes, stirring occasionally. The vegetables should be soft but still hold their shape, and the broth will thicken slightly as the pumpkin softens. If you prefer a looser soup, add up to 1 cup (240 ml) hot water or broth.
Season and serve. Remove the bay leaf. Stir in the sour orange juice and cilantro, then taste the broth. Add more salt, pepper, or citrus a little at a time; the citrus should brighten the savory broth rather than make it sharply sour. Rest the soup off the heat for 5 minutes before ladling it into bowls. The stated cook time includes blanching, simmering, and the final vegetable simmer; a particularly firm batch of tripe may need an additional 15 to 30 minutes.

Tips

Choose the right cut. Honeycomb tripe has a textured surface and blanket tripe is flatter; either works. Buy tripe from a refrigerated meat counter or a well-stocked Latin or Caribbean market, and keep it cold until cooking. If your package is already cleaned and blanched, you can still do the short blanch in this recipe for a milder aroma, or skip it and reduce the cook time by 10 minutes.
Keep the simmer gentle. A hard boil can make the broth cloudy and may leave the tripe chewy. Look for occasional small bubbles, not a rolling boil. If the tripe is still firm after the listed simmer, give it more time before adding the vegetables, which would otherwise turn mushy.
Use an accessible citrus substitute. Sour orange, sometimes sold as naranja agria, gives the soup a rounded, lightly bitter citrus note. Orange juice mixed with lime makes a practical substitute; plain lime alone tastes sharper, so start with less and adjust at the end.
Adjust the texture deliberately. Auyama breaks down and lends body to the broth, while potatoes and plantain make the soup more substantial. For a thicker bowl, mash a few soft pumpkin pieces against the side of the pot and stir them back in rather than adding flour or cornstarch.

Serving Suggestions

Serve mondongo hot in deep bowls, with rice on the side or a scoop of white rice in the bowl to absorb the broth. Dominican-style white rice, crusty bread, or warm cassava are all useful for catching the savory liquid. Put lime or sour orange wedges on the table for anyone who wants more brightness, and offer sliced avocado or a simple green salad to balance the rich stew. If serving a group, keep the soup covered over very low heat and stir from the bottom so the vegetables do not stick; avoid letting it boil hard while people are being served.

Variations

Make it without plantain: Leave it out for a more straightforward tripe-and-vegetable soup. Add another small potato if you want to keep the bowl just as filling. Use yautía: Peeled yautía (taro root) is a traditional-feeling addition in some Caribbean soups. Replace up to 1 cup (150 g) of the potato with cubed yautía; it gives the broth a starchy, slightly earthy quality. Auyama can be hard to find outside Latin markets, so use peeled kabocha squash or another firm winter squash in the same amount. The flavor will be a little sweeter and less distinctive, but it still softens into a satisfying broth.

Make the broth lighter: Use water instead of beef broth, then taste carefully at the end and adjust salt and citrus. Add heat: Simmer a whole Scotch bonnet or habanero pepper in the soup for a few minutes, keeping it intact, then remove it before serving; piercing or chopping it makes the soup much hotter. Use a pressure cooker: Follow the appliance manual for the amount of liquid and tripe setting, and cook the tripe until fork-tender before adding the vegetables. Release pressure as directed by the manufacturer, add the vegetables, and simmer uncovered until tender so they do not overcook under pressure.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in shallow, covered containers. Mondongo keeps for 3 to 4 days in the refrigerator. The tripe and vegetables can absorb broth as they sit, so loosen each portion with a splash of water or broth when reheating. Warm on the stovetop over medium-low heat, stirring gently, or microwave in a covered microwave-safe bowl, stirring partway through. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. For longer storage, freeze portions for up to 2 to 3 months for best quality; thaw overnight in the refrigerator and reheat thoroughly. Potatoes may become softer after freezing, but the soup remains suitable for serving.

Frequently Asked Questions

What does tripe taste and feel like?

Tripe has a mild, savory flavor that takes on the broth and seasonings around it. Properly simmered, it is tender and pleasantly chewy rather than crisp or meaty like a steak. Honeycomb tripe has a more textured bite, while flatter blanket tripe is more uniform. If it feels rubbery, it generally needs more gentle cooking time.

Do I have to blanch the tripe first?

Blanching is helpful when you want a cleaner, milder aroma, especially if the package does not say the tripe has already been blanched. Boil it for the brief 10 minutes in the recipe, drain, and start the main simmer in fresh broth. Blanching does not tenderize it on its own, so do not shorten the slow simmer unless the tripe is already fully cooked and the package directions say it is ready to eat.

Can I make Dominican mondongo a day ahead?

Yes. The flavors settle together overnight, and the soup reheats well. Refrigerate it within 2 hours in shallow containers, then warm it gently the next day to 165°F (74°C). If you know you will make it ahead, you can cook the vegetables just until tender rather than very soft, since they will soften a little more during reheating.

Why is my tripe still tough after cooking?

Tripe can vary in thickness and in how it was prepared before sale, so the listed time is a guide rather than a guarantee. Keep it at a gentle simmer and test a piece every 15 minutes. If it is tough, continue cooking the tripe in its broth before adding the vegetables; adding the vegetables early can leave them overcooked by the time the tripe is ready.

Can I leave out the auyama or sour orange?

Yes. The soup will still work without auyama, though the broth will be thinner and less naturally sweet; add a little more potato or another firm squash if desired. If sour orange is unavailable, use the orange-and-lime mixture in the ingredient list. Add citrus near the end so its fresh flavor remains noticeable and you can control the acidity.
