Sinigang na Corned Beef: A Tangy Filipino Soup

Sinigang na corned beef is a Filipino-style sour soup that combines canned corned beef, vegetables, and a tamarind-seasoned broth. It comes together faster than versions made with raw meat, while tomato, radish, and leafy greens balance the rich, salty beef; sourness and vegetables vary by household and region.

Ingredients

1 tablespoon (15 ml) neutral cooking oil
1 medium yellow onion, thinly sliced, about 1 cup (150 g)
2 medium tomatoes, cut into wedges, about 1½ cups (270 g)
1 can corned beef, about 12 ounces (340 g)
6 cups (1.4 L) water, plus a little more if needed
1 medium daikon radish, peeled and sliced into ¼-inch (6 mm) rounds, about 10 ounces (280 g)
1 packet sinigang sa sampalok (tamarind soup mix), about 1.4 ounces (40 g), or to taste
1 tablespoon (15 ml) fish sauce, plus more to taste
1 small eggplant, cut into bite-size pieces, about 8 ounces (225 g)
6 ounces (170 g) fresh green beans, trimmed and cut into 2-inch (5 cm) lengths
4 ounces (115 g) fresh spinach or water spinach (kangkong), roughly chopped
¼ teaspoon (0.5 g) freshly ground black pepper, or to taste
Steamed rice, for serving

Instructions

Prepare the vegetables. Slice the onion and radish, cut the tomatoes and eggplant, trim the beans, and rinse and drain the greens. Keep the spinach or kangkong separate; it needs only a brief simmer at the end.
Soften the aromatics. Heat the oil in a medium-large pot over medium heat. Add the onion and cook for 3–4 minutes, stirring, until softened. Add the tomatoes and cook for 4 minutes, pressing a few pieces with the spoon so they begin to release their juices.
Warm the corned beef. Add the canned corned beef and break it into large flakes with a spoon. Stir for 2–3 minutes to coat it in the onion and tomato mixture. Canned corned beef is already cooked; this step warms it and builds flavor rather than cooking raw meat.
Simmer the radish. Pour in the water and bring it to a boil. Add the radish, reduce the heat to maintain a steady simmer, and cook uncovered for 12 minutes, or until a knife slides into a slice with slight resistance.
Season the broth. Stir in the tamarind soup mix and fish sauce until dissolved. Add the eggplant and green beans, then simmer for 6–8 minutes, until the eggplant is tender but still holds its shape and the beans are cooked but not limp. Follow the soup-mix package’s dilution guidance if it differs substantially; packets vary in strength and salt.
Finish and adjust. Stir in the spinach or kangkong and simmer for 1–2 minutes, just until wilted. Taste the broth. Add more tamarind mix for sharper sourness, a little water if it is too concentrated, or fish sauce and pepper as needed. Serve hot with steamed rice.

Tips

Season gradually. Corned beef, fish sauce, and packaged sinigang mix can all be salty. Begin with the listed amounts, taste after the vegetables are tender, and add extra seasoning in small increments.
Use fresh tamarind if you prefer. Replace the packet with about ½ cup (120 ml) strained tamarind extract, then adjust to taste. Fresh extract has a less standardized sourness and adds no packet seasoning, so you may need extra fish sauce or salt.
Choose a good substitute for kangkong. Water spinach can be hard to find; ordinary spinach works well, though it is softer and has a different texture. Add either only at the end so it does not overcook.
Keep the vegetables intact. Cut the radish into fairly even rounds and avoid a hard boil after adding the eggplant. A steady simmer helps everything cook evenly without turning the vegetables to mush.

Serving Suggestions

Ladle the soup and its vegetables into bowls, making sure each serving gets some corned beef and plenty of broth. Serve with hot steamed white rice, either on the side or spooned into the bowl. A small dish of fish sauce with sliced fresh chili is an optional table condiment for diners who want extra salt or heat; keep it separate so everyone can season their own portion. The broth is the main event, so offer extra rice for soaking up its sour, savory flavor.

Variations

For a more pronounced sour broth, add extra tamarind mix a little at a time or use strained fresh tamarind extract. Calamansi or lemon can provide a brighter citrus note, but they taste different from tamarind; add a small squeeze at the table rather than replacing all the tamarind. If daikon is unavailable, use a similar amount of turnip, understanding that it has a slightly earthier flavor. Okra or sliced taro can replace some of the eggplant or beans; adjust simmering time so each vegetable becomes tender without falling apart.

You can also add a small green chili whole for gentle aroma, removing it before serving, or sliced chili for more heat. For a lighter bowl, use less corned beef and increase the vegetables, adding water only as needed and correcting the seasoning after the broth simmers. These are practical variations rather than fixed rules: sinigang recipes commonly change with available souring ingredients and vegetables.

Storage and Reheating

Refrigerate leftover soup within 2 hours of cooking in a covered, shallow container. It keeps for 3–4 days in the refrigerator. The vegetables soften as they sit, so for the best texture, store the broth and solids together but avoid repeatedly heating the whole pot. Freeze portions in airtight freezer-safe containers for up to 2–3 months for best quality; thaw overnight in the refrigerator. Reheat only the portion you plan to eat on the stove until steaming throughout, stirring occasionally, or in a microwave with a loose cover, stirring partway through. Leftovers should reach 165°F (74°C) when checked with a food thermometer.

Frequently Asked Questions

Is canned corned beef already cooked?
Yes. Commercial canned corned beef is cooked during processing, so this recipe only needs to heat it in the soup. If using a different product, check its package directions and handle it accordingly.

Can I make this without sinigang mix?
Yes. Use strained fresh tamarind extract, starting with about ½ cup (120 ml), and add more until the broth is as sour as you like. Since the mix also contributes seasoning, taste carefully and adjust with fish sauce or salt.

Why is my broth too salty?
The corned beef and soup mix may both contribute considerable salt. Dilute the broth with hot water a little at a time, then add extra tomato or vegetables if available. A squeeze of calamansi or lemon can brighten the flavor, but it will not remove salt.

Can I prepare the soup ahead?
Yes. Make it up to a day ahead and chill it promptly. The flavors will mingle, but greens and softer vegetables may lose some texture. For a fresher finish, reheat the broth and firmer vegetables, then add a handful of fresh spinach or kangkong just before serving.

Can I use another kind of corned beef?
Cooked leftover corned beef can replace the canned kind; chop or shred it and warm it in the pot. It may be less salty or more strongly seasoned, so adjust fish sauce and tamarind mix only after tasting the finished broth.

What if I cannot find daikon?
Turnip is a convenient substitute in the same quantity. It brings a slightly earthier flavor, but cooks similarly when cut into thin rounds. Add it at the same point as the daikon and check tenderness before moving on.
