Sinigang na Baboy Recipe: Tangy Filipino Pork Soup

Sinigang na baboy is a Filipino pork soup with a savory, distinctly sour broth, usually flavored with tamarind and served with vegetables and rice. This Tagalog-style version uses pork ribs or shoulder, daikon, eggplant, long beans, and leafy greens; the exact vegetables and sourness often vary by household and region.

Ingredients

2½ lb (1.13 kg) bone-in pork shoulder or pork ribs, cut into 2–3-inch (5–7.5 cm) pieces
10 cups (2.4 L) water
1 medium yellow onion (about 7 oz/200 g), peeled and quartered
3 medium ripe tomatoes (about 1 lb/450 g), cut into wedges
2 tbsp (30 ml) fish sauce, plus more to taste
¼ cup (60 ml) unsweetened tamarind concentrate, or 1 packet (about 40 g) sinigang seasoning mix; see the notes below
8 oz (225 g) daikon radish, peeled and cut into ½-inch (1.3 cm) half-moons
8 oz (225 g) taro root, peeled and cut into 1½-inch (4 cm) chunks; optional
1 medium Asian eggplant (about 8 oz/225 g), cut into 2-inch (5 cm) pieces
6 oz (170 g) long beans, cut into 2-inch (5 cm) lengths
6 oz (170 g) fresh kangkong, also called water spinach, rinsed and cut into short lengths
½ tsp (1 g) freshly ground black pepper
1–2 long green chilies (about 1 oz/28 g), whole or split lengthwise; optional
Fine salt, as needed after tasting

If kangkong is not available, use 4 oz (115 g) baby spinach or watercress, added at the end. Spinach is milder and softer; watercress brings a peppery note. Tamarind concentrate is a convenient stand-in for fresh tamarind pulp. If using a seasoning packet instead, start with one packet and follow its label if it specifies a different amount; packets often contain salt, so wait to add extra salt until the soup is finished.

Instructions

Rinse the pork under cool running water and pat it dry. Put the pork in a large, heavy pot with the water, onion, tomatoes, and fish sauce. Set the pot over medium-high heat and bring the liquid to a gentle boil, which should take about 10–12 minutes. As foam rises, skim it off with a spoon for a cleaner-looking broth. Avoid a hard rolling boil, which can break up the tomatoes and make the soup cloudier.
Lower the heat until the broth bubbles gently, partially cover the pot, and simmer the pork for 65 minutes. Turn the pieces once or twice so they cook evenly and check that the liquid stays at a gentle simmer; add a little hot water if the pork becomes exposed. The meat should be tender when pierced with a fork. If your pieces are especially large or still firm, continue simmering in 10-minute increments until tender.
Check the thickest pork pieces with a food thermometer, avoiding the bone. USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum internal temperature for whole cuts of pork. The long simmer should take the pork well beyond that temperature; turn off the heat and leave the meat in the hot broth for at least 3 minutes before serving.
Stir in the tamarind concentrate and black pepper. If using sinigang seasoning mix instead, add the packet gradually according to its instructions. Taste the broth before adding more souring ingredient: concentrate strength varies, and the finished soup should be noticeably tangy but still savory. If the broth tastes too intense, dilute it with ½ cup (120 ml) hot water; if it needs more sourness, add concentrate 1 tablespoon (15 ml) at a time.
Add the taro, if using, and daikon. Simmer for 10 minutes, or until the vegetables are beginning to soften. Taro releases starch and gives the soup a fuller texture, while daikon stays lighter and mildly sweet. Keep the heat gentle so the taro pieces hold together rather than dissolving into the broth.
Add the eggplant and long beans. Simmer for about 7 minutes, until the eggplant is tender and the beans are cooked but still retain their shape. If you prefer very soft vegetables, give them a few extra minutes, but keep an eye on the eggplant because it can become mushy quickly.
Add the kangkong and green chilies. Cook for about 2 minutes, just until the leaves wilt and the stems are tender. For spinach or watercress, add the greens at this same final stage. Taste the broth and adjust with fish sauce for savoriness, salt if needed, or a little more tamarind for a sharper sour edge.
Turn off the heat and serve the soup hot, making sure each bowl gets pork, broth, and a mix of vegetables. The listed cooking time is about 1 hour 35 minutes, including bringing the pot to a simmer and cooking the vegetables; the pork’s tenderness, rather than the clock alone, is the best final check.

Tips

Choose a cut with some connective tissue. Pork shoulder and ribs become tender and give the broth a fuller flavor during a long simmer. Lean pork loin cooks faster but can turn dry and will make a less rich soup, so it is not the best direct substitute for this timing.
Build sourness slowly. Tamarind products differ in strength, and seasoning packets may include salt or other flavorings. Add the souring ingredient in stages and taste after each addition. If the broth is too sour, a little hot water and another small splash of fish sauce can bring it back into balance.
Keep the vegetables in good shape. Add firm roots first, then eggplant and beans, and leafy greens last. Cutting vegetables into similarly sized pieces helps them cook evenly. Avoid boiling vigorously after the vegetables go in, as that can break them apart and make the broth cloudy.
Prepare ahead without overcooking. You can chop the vegetables and refrigerate them in separate covered containers for up to a day. Keep the leafy greens apart from the firmer vegetables and add them only when reheating or just before serving, so they do not become limp.

Serving Suggestions

Serve sinigang na baboy in deep bowls with plenty of broth, pork, and vegetables. Steamed white rice is the classic partner: eat it alongside the soup or spoon broth over it. A small dish of fish sauce with sliced green chili lets diners season their own portions, but taste the soup first because the broth is already seasoned.

For a more substantial Filipino meal, pair the soup with plain rice and a simple vegetable or grilled dish. Sinigang is already generously filled, so elaborate sides are not necessary. If serving family-style, keep the pot covered between ladles to retain heat, and provide a spoon for broth as well as a fork or chopsticks for the pork and vegetables.

Variations

Use fresh tamarind pulp: Instead of concentrate, simmer about 8 oz (225 g) peeled fresh tamarind pulp with 2 cups (475 ml) water for 15 minutes, mash it, and strain the liquid into the soup. Fresh pulp can be less predictable in sourness, so taste and add it gradually. Frozen tamarind pulp can also work if it is unsweetened.

Make it without taro: Leave the taro out for a clearer, lighter broth, or replace it with 8 oz (225 g) peeled potato. Potato is not the same in flavor or texture, but it adds a soft, starchy bite. Add it with the daikon so it has enough time to cook through.

Adjust the vegetable mix: Mustard greens, watercress, or baby spinach can stand in for kangkong. Green beans can replace long beans, and radish can be omitted if unavailable. These swaps change the texture and sometimes the mild bitterness of the soup, but the key balance of sour broth, savory pork, and vegetables remains.

Change the souring ingredient: Some cooks use calamansi, green mango, guava, or another souring ingredient instead of tamarind. Each gives the broth a different aroma and kind of acidity, so start with a modest amount and taste as you go. A seasoning packet is the simplest shortcut, though its flavor and salt level will vary by brand.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking. Let a large pot cool more quickly by dividing the soup among shallow containers, then cover and refrigerate; cooked soup keeps for 3–4 days. Store the broth, pork, and vegetables together if convenient, but know that eggplant and leafy greens soften further as they sit. For better vegetable texture, store the greens separately when possible and add fresh greens to portions as they are reheated.

For longer storage, freeze cooled soup in airtight, freezer-safe containers for up to 2–3 months for best quality. Leave a little room at the top for expansion. Thaw overnight in the refrigerator, or reheat from frozen over low heat with a splash of water. Reheat only the amount you plan to eat, bringing leftovers to 165°F (74°C) throughout; check with a food thermometer and stir the soup so it heats evenly. Avoid repeatedly cooling and reheating the full pot.

Frequently Asked Questions

What does sinigang na baboy mean?

Sinigang na baboy means pork sinigang. Sinigang is a Filipino sour soup, and na baboy identifies pork as the main meat. This version is written in English but follows a familiar Tagalog-style preparation with pork, sour broth, and vegetables.

Can I use pork belly instead of ribs or shoulder?

Yes. Pork belly makes a richer, fattier broth and can be used in a similar quantity. Skim excess fat from the surface as it simmers, and begin checking tenderness around the same time as the recipe directs. The USDA safe minimum still applies: whole cuts of pork should reach 145°F (63°C) and rest for 3 minutes.

Can I make the soup less sour?

Yes. Begin with less tamarind concentrate than listed, then add more a tablespoon at a time after the pork is tender. If using a seasoning packet, add only part of it first and check its directions. A small amount of hot water can soften an overly sharp broth, though it also dilutes the savory flavor.

Why is my pork still tough?

Pork shoulder and ribs need time for their connective tissue to soften. Keep the soup at a gentle simmer and cook the pork longer in 10-minute increments, checking with a fork. A vigorous boil does not make the meat tender faster and may leave the broth cloudy while the outside of the pork breaks down.

Can I make sinigang na baboy a day ahead?

Yes. Cool and refrigerate the cooked soup within 2 hours, then reheat it the next day to 165°F (74°C). The broth often tastes well blended after resting, but vegetables will be softer. For the freshest texture, cook the pork and broth ahead, then add the vegetables while reheating and finish with leafy greens at the end.
