Beef Sinigang Recipe: Filipino Tamarind Soup

Beef sinigang is a Filipino sour soup made with tender beef, vegetables, and a broth brightened with tamarind. This version simmers beef chuck until soft, then adds vegetables in stages so they stay pleasantly tender rather than falling apart; family and regional versions vary in their choice of souring agent and vegetables.

Ingredients

4 oz (113 g) unsweetened tamarind pulp block
1 cup (240 ml) boiling water, for the tamarind
2 1/2 lb (1.13 kg) beef chuck, cut into 2-inch (5 cm) pieces
1 tbsp (15 ml) neutral cooking oil
1 large yellow onion, about 8 oz (225 g), cut into wedges
2 medium ripe tomatoes, about 10 oz (280 g), cut into wedges
8 cups (1.9 L) water or unsalted beef broth
2 tbsp (30 ml) fish sauce, plus more to taste
1 tsp (2 g) whole black peppercorns
1 lb (450 g) daikon radish, peeled and cut into 1/2-inch (1.25 cm) half-moons
8 oz (225 g) long green beans, trimmed and cut into 2-inch (5 cm) lengths
1 medium Asian eggplant, about 10 oz (280 g), cut into 1-inch (2.5 cm) pieces
1 small bunch water spinach (kangkong), about 8 oz (225 g), stems and leaves cut into 3-inch (7.5 cm) lengths
1/2 tsp (3 g) fine salt, or as needed
1/4 tsp (0.5 g) freshly ground black pepper, or to taste

Instructions

Soak and strain the tamarind. Put the tamarind pulp in a heatproof bowl and pour over the boiling water. Leave it to soften for 10 minutes. Mash it with a fork or clean fingers, then pour it through a fine-mesh strainer into a second bowl, pressing the pulp to extract its sour liquid. Discard the tough fibers and seeds. Set the strained liquid aside. This soaking time is included in the prep estimate.
Prepare the beef and vegetables. While the tamarind soaks, cut the beef into even pieces and prepare the onion, tomatoes, radish, beans, eggplant, and water spinach. Pat the beef dry with paper towels; drier surfaces brown more readily. Keep the vegetables separate because they go into the pot at different times.
Brown the beef. Heat the oil in a large heavy pot or Dutch oven over medium-high heat. Working in batches so the pieces are not crowded, brown the beef on two or three sides, about 10 minutes total. Transfer the browned pieces to a plate. Browning adds savory depth, but the meat does not need to be cooked through at this stage. If the pot becomes very dark or starts smoking, lower the heat.
Start the broth. Add the onion and tomatoes to the pot and cook for 4 minutes, stirring and scraping up the browned bits. Return the beef and any juices to the pot. Add the water or broth, fish sauce, peppercorns, and strained tamarind liquid. Stir, bring the liquid just to a boil, then reduce the heat so it simmers gently. Cover with the lid slightly ajar.
Simmer until the beef is tender. Simmer for about 1 hour 45 minutes, checking occasionally that the liquid is bubbling gently rather than boiling hard. If foam gathers on top during the first part of cooking, skim it off. The beef should yield easily when pressed with a fork. Add a splash of hot water if the liquid level drops too much; keep the pieces mostly covered. Timing can vary with the size of the pieces and the cut, so continue simmering in 10-minute increments if needed.
Check the beef and add the firm vegetables. Use a food thermometer to check the center of the largest beef piece. USDA FSIS lists 145°F (63°C), followed by a 3-minute rest, as the safe minimum for whole cuts of beef; this long simmer should take the beef well beyond that temperature as it becomes tender. Add the daikon and simmer for 8 minutes.
Add the remaining vegetables in stages. Stir in the long beans and simmer for 5 minutes. Add the eggplant and cook for another 5 minutes, or until it is tender but still holds its shape. Add the water spinach and cook for 2 minutes, just until the leaves wilt and the stems turn bright green. Turn off the heat and let the pot stand for 3 minutes before serving.
Season and serve. Taste the broth. Add salt and black pepper as needed, and add a little more fish sauce if it needs savory depth. For a sharper sour flavor, stir in a small amount of additional tamarind liquid; for a gentler broth, add hot water a few tablespoons at a time. Serve while hot.

Tips

Choose a cut suited to a long simmer. Chuck has enough connective tissue to become tender and flavorful as it cooks. Beef shank is another good option, though pieces with bone may need extra time and can make the broth richer. Lean steak tends to turn dry and firm if simmered for this long.
Control the sourness gradually. Tamarind pulp varies in strength and tartness. Begin with the strained liquid from the stated amount, then adjust at the end. Add more for a punchier soup or dilute with hot water if the broth tastes too sharp. Taste before adding salt because fish sauce is already salty.
Keep the simmer gentle. A rolling boil can make beef fibers tighten and can break up the vegetables. Look for occasional small bubbles and keep the lid partly open. If the broth reduces too much before the beef is tender, add hot water rather than cold.
Use the right substitute for the souring agent. Tamarind pulp blocks can be difficult to find. A packaged sinigang soup-base mix is a practical substitute; use the packet’s directions, starting with less than the full amount and adjusting to taste. It usually contains salt and seasonings, so reduce or omit added salt and expect a more seasoned, less purely tamarind-forward broth. Bottled unsweetened tamarind concentrate can also work, but it is often stronger than pulp liquid, so add it a spoonful at a time.

Serving Suggestions

Serve beef sinigang hot in deep bowls, with beef, vegetables, and plenty of broth in each portion. Steamed white rice is the classic companion: eat it alongside the soup or spoon some broth over the rice. The rice softens the sharpness of the tamarind and makes the meal more substantial. A small dish of fish sauce with sliced fresh chile can be offered at the table for people who want extra salt or heat, but taste the soup before adding either.

For a balanced bowl, include a mix of beef, daikon, beans, eggplant, and water spinach rather than filling a serving with only broth or meat. If the soup is part of a larger meal, it pairs well with plain rice and simply prepared sides that do not compete with its sour broth. Put extra rice and fish sauce on the table so each person can adjust their serving.

Variations

Use beef shank: Replace the chuck with the same weight of beef shank, cut into manageable pieces. The bones and connective tissue give the broth a fuller body, but the meat may take longer to soften. Check it with a fork and extend the simmer in short increments before adding the vegetables.

Swap the vegetables: Taro, bok choy, mustard greens, or wedges of green banana appear in some versions. Add dense vegetables early enough to cook through and leafy greens near the end. If using bok choy instead of water spinach, add the stems first and the leaves for the final couple of minutes.

Make it with a seasoning mix: If tamarind pulp is unavailable, use a sinigang soup-base packet according to its package directions. Since packet sizes and salt levels differ, add it gradually after the beef is tender, taste the broth, and avoid adding extra salt until the end. The result is convenient and tangy, though its flavor is generally more seasoned than a broth made from strained tamarind.

Adjust the souring agent: Tamarind is common, but some cooks use other souring ingredients, such as green mango, calamansi, or guava, depending on preference and availability. Each gives the broth a different aroma and kind of acidity, so start with a modest amount and taste as you go. Do not combine several souring agents in full quantities without tasting between additions.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in shallow, covered containers. Beef sinigang keeps for 3 to 4 days in the refrigerator. The broth and beef store well, although the vegetables may soften further over time; if you expect leftovers, cook the vegetables just until tender rather than very soft.

Reheat only the portion you plan to eat, either in a saucepan over medium heat or in a microwave-safe bowl. Stir occasionally and heat leftovers to 165°F (74°C), checking with a food thermometer. If the broth tastes more concentrated after storage, add a little water while reheating and adjust the seasoning. For longer storage, freeze the cooled soup in airtight freezer-safe containers for about 2 to 3 months for best quality. Thaw it in the refrigerator and reheat to 165°F (74°C); vegetables may be softer after freezing.

Frequently Asked Questions

What does sinigang taste like?
Sinigang is known for a distinctly sour broth, balanced by savory ingredients such as beef, fish sauce, and vegetables. Tamarind gives this version a bright, fruity tartness. The exact balance varies: add strained tamarind gradually and season the finished soup to suit your preference.

Can I make beef sinigang with a packaged mix?
Yes. A sinigang soup-base mix is a common, convenient alternative to preparing tamarind pulp. Follow the packet instructions, but add the powder in stages and taste before using the whole packet. Many mixes are salty, so reduce the fish sauce or skip additional salt until the broth is finished.

Why is my beef still tough?
It may simply need more time. Chuck and shank become tender at different rates depending on the size of the pieces and how steadily the pot simmers. Keep the broth at a gentle simmer and check every 10 minutes. Wait until the beef yields easily before adding vegetables, or they may become overcooked while the meat softens.

Can I make the soup ahead?
Yes. You can cook the beef and broth a day ahead, cool and refrigerate them promptly, then bring the soup to a simmer and cook the vegetables shortly before serving. This helps preserve their texture. If the soup is already fully assembled, refrigerate it within 2 hours and use it within 3 to 4 days.

What can I use instead of water spinach?
Use bok choy, spinach, or another tender leafy green. Bok choy stems need a little more cooking than spinach leaves, so add the stems first and the leaves near the end. The flavor and texture will differ from kangkong, but the soup will still work well.

How do I make the broth less sour?
Stir in hot water a little at a time until the broth tastes balanced, then check the salt and fish sauce again. If you have not added all the strained tamarind liquid yet, hold some back. Do not try to correct an overly sour pot with a large amount of sugar; dilution and careful seasoning keep the soup’s flavor more balanced.
