In many Filipino households, canned sardines are more than just a low-budget backup. They’re quick, cheap, and comforting, especially when transformed into sinigang. This soup version, sinigang na sardinas, can be prepared on rainy days or when time and money are tight. Just like the traditional pork or shrimp versions, it’s sour and comforting but has that gentle fish taste that makes it lighter.
Personally, I like sinigang na sardinas most when paired with warm white rice and a side of crispy dried fish. That mix of sour broth and salty crunch really hits the spot. For this version, I used canned mackerel in oil instead of regular sardines, added miso for a richer broth, and threw in more vegetables than usual to bulk it up. The miso gives it a heartier finish, while Maggi Magic Sinigang with Gabi ties the flavors together.
What is Sinigang na Sardinas?
Sinigang na sardinas is a tamarind-based Filipino soup that uses canned sardines or mackerel as the meat. “Sinigang” comes from the Tagalog word “sigang,” which means to stew in a sour broth, usually tamarind. This version swaps out traditional pork or bangus with canned fish, making it faster and more affordable.
In the Philippines, people like it for how fast it comes together, especially when you’re short on ingredients or budget. for familiar flavors without needing access to specialty meats. One thing most people don’t expect is how good canned mackerel can taste in a well-seasoned soup, and using sardinas is just as traditional in many rural areas.
Ingredients and Purpose
Mackerel canned (45 oz) – This serves as the core protein. Mackerel in oil has a deeper flavor than water-packed sardines and holds up well in broth.
Maggi Magic Sinigang with Gabi (75 grams) – This tamarind mix brings the signature sourness. The gabi (taro) element also thickens the broth a little, giving it a fuller mouthfeel.
Okra (12 pieces) – Okra adds a subtle earthy note and a bit of natural thickness when simmered. I keep them whole to avoid sliminess.
String beans (15 pieces) – These stretch the dish and soak up the broth well. They’re soft but keep a bit of chew when cooked right.
Daikon radish (6 oz) – Adds a mild sweetness that helps round out the tanginess. I slice them thin so they soften quickly.
Eggplant (3 pieces) – Softens easily and absorbs the sour broth. I like using the long purple kind, sliced diagonally.
Long green peppers (4 pieces) – Not spicy, just fragrant. They give a soft peppery taste without heat.
Water spinach (1 bunch) – Also called kangkong, this leafy green finishes the dish with a fresh bite. Add it last so it doesn’t overcook.
Onions (2 pieces) – Start the base with these. They mellow out when sautéed and help bind the aromatics.
Garlic (8 cloves) – Crushed and chopped for full release of flavor. Don’t skip this—it gives body to the broth.
Ginger (4 thumbs, crushed) – Lifts the fishy smell and adds gentle heat. I don’t peel it if the skin is thin.
Tomatoes (5 pieces) – A natural acid that pairs well with tamarind. I use ripe ones to deepen the broth’s color.
Miso paste (1/4 cup) – Adds richness and an extra layer of flavor. This isn’t in all sinigang versions, but it makes a difference here.
Water (2 quarts) – Used in two stages to build the broth. Start with 1.5 quarts and add the rest later for proper layering.
Fish sauce and ground black pepper (to taste) – These season the broth and adjust saltiness. I taste as I go and always finish with a splash.
Cooking oil (3 tablespoons) – Needed to sauté the base and build flavor before adding liquid
Best Ways to Enjoy Sinigang na Sardinas
Some meals just feel like they were invented for rainy days, and this one tops that list. In the Philippines, sinigang na sardinas is common during rainy days when the weather turns damp and a hot bowl of soup hits differently. It’s also cooked on days when payday feels too far away, because you can stretch one can of fish to feed many.
At home, people usually enjoy this dish with white rice, patis (fish sauce) with sili on the side, and something crunchy like fried fish lumpia or tuyo (Filipino dried fish). And if you haven’t had it for breakfast yet, try it. It’s one of those meals that wakes you up better than a cup of barako.
How This Sinigang na Sardinas Stands Out
Many versions online lean either too basic or too rushed. Some recipes just throw everything in the pot and boil all at once. Mine takes the canned mackerel seriously. I give it room to shine by adding the oil back into the broth for extra flavor, not just tossing it aside. I also sauté the aromatics properly instead of boiling them raw, which helps build a stronger broth without needing more seasoning.
What sets this apart even more is the use of miso with the tamarind mix. I treat canned fish with the same respect, so the use of miso is required. It deepens the broth without adding fishiness, something missing from most short-form recipes.
If you’re used to the usual pork sinigang or prefer fast meals without shortcuts, you’ll probably enjoy how this version blends efficiency and flavor. Next, I’ll guide you step-by-step on how I put this all together in my kitchen.
How to Cook Sinigang na Sardinas
Start with the base – Heat 3 tablespoons of oil in a large pot. Sauté 2 onions until the layers soften, then stir in 4 thumbs of crushed ginger and 8 chopped garlic cloves. Cook until the garlic just begins to brown. This step sets the tone for the broth.
Add the body and aromatics – Toss in 5 chopped tomatoes and stir for 1 minute. Pour the oil from the canned mackerel directly into the pot, then season with 1 tablespoon of fish sauce and ½ teaspoon of ground black pepper. Stir well to combine everything before adding liquid. These flavors need time in the pot first.
Build the broth – Add ¼ cup of miso paste and pour in 1.5 quarts of water. Let it come to a boil to help the miso melt into the liquid fully. This broth base is now ready for the heavier vegetables.
Cook the root vegetables – Add 6 ounces of daikon radish and simmer over medium heat for about 5 minutes. Then stir in the 75 grams of Maggi Magic Sinigang with Gabi powder. This thickens and sours the broth just right without overpowering the other ingredients.
Layer in the soft vegetables – Put in 3 sliced eggplants and boil for 2 minutes. Follow up with 12 okra, 4 whole long green peppers, and 15 trimmed string beans. Stir gently and let the soup reach a boil again before the next step.
Add the remaining liquid and mackerel – Pour in the remaining ½ quart of water, cover the pot, and let it re-boil. Then gently drop in the 45 oz of canned mackerel pieces. Stir softly to avoid breaking them apart. You want the fish to stay in big, scoopable chunks.
Finish with greens and final seasoning – Add 1 bunch of water spinach (kangkong) and cook for another 2 to 3 minutes. Taste the broth and add more fish sauce or black pepper if needed. Serve hot and eat with rice while everything is still piping warm.
Tips & Tricks
Strain the mackerel oil before using it. The oil from canned mackerel adds flavor, but sometimes you get small bits of bones or mushy residue. I run it through a small kitchen strainer before pouring it back into the pot. This keeps the broth clean and smooth without losing that rich layer of taste. Plus, it helps avoid any fishy bitterness.
Use miso sparingly if you’re unsure. If it’s your first time mixing miso with sinigang, start with half the amount and taste the broth first. Some miso brands are stronger than others. I’ve tried versions that turn the soup into something too earthy, so this is where small tasting adjustments matter. Once you get used to the flavor, you’ll know how far you want to go with it.
Add kangkong last and never early. Leafy greens overcook fast. If you add them too early, they’ll melt into the broth and leave behind stringy bits. I always toss in the kangkong during the last 2 to 3 minutes and immediately turn off the heat once they’re tender. That way, they stay fresh and bright green.
Cut daikon radish thin. This isn’t a hard root like carrot, but it does take time to soften if left in chunks. I slice it thinly, about half a centimeter thick, so it cooks through in five minutes without falling apart. It also absorbs the broth better when it’s thinner, which helps mellow out the sourness.
Don’t over-stir after adding the mackerel. Once the fish is in the pot, treat it gently. Stirring too much will break the pieces and leave you with a mushy soup. I just use a ladle to slowly mix the broth around it and let the heat finish the job.

What to Have With Sinigang na Sardinas
For Filipinos, sinigang is rarely served on its own. It sits beside a few dependable companions on the dining table. A bowl of hot white rice is the most obvious, and most necessary, pairing. Some also enjoy this with crispy danggit or tuyo fried rice for added saltiness and texture. That kind of combo makes the sour broth stand out even more. These work well because they don’t clash with the soup’s acid, and they extend the meal for bigger households. Aside from those fried rice versions, you can also expect a warm bowl of sinigang with anything that’s fried. I suggest working with fritters like this tasty Vegetable Okoy or Fried Eggplant Fritters.

If sinigang na sardinas hits your budget and comfort zone, wait until you see how else sardines can shine. These next few dishes come from the same staple but branch out into stews, sautés, and even meat replacements. They’re practical, smart, and rooted in Filipino household habits.
Ginataang Mackerel with Spinach – This dish blends the richness of coconut milk with the soft bite of mackerel. While sinigang builds flavor through sourness, ginataan goes the creamy route. If you want the same protein with a gentler profile, this is your next best bet.
Tortang Noodles at Sardinas – Here, sardines are transformed into a fried patty with noodles. Unlike sinigang, which is brothy and loose, this one’s compact and filling. Give it a shot for merienda or baon that still makes use of canned sardines.
Burger Steak Sardinas – This recipe forms patties out of sardines and covers them in a mushroom gravy. It’s a fast, inventive take on fast food but keeps things affordable. If you’re craving something saucy without going back to soup, this is a smart detour.
Ginisang Upo with Sardinas – This sauté combines sardines with upo (bottle gourd) in a thin broth. It shares that broth-like base with sinigang, but it’s less acidic and more neutral. Try this when you want something lighter but still comforting.
Just like sinigang na sardinas, all of these recipes prove that canned fish isn’t just for emergencies, it can lead the meal. If you’re working with a budget, or just short on prep time, these are reliable go-to dishes that won’t disappoint.

Notes
Do not throw away the mackerel oil. This oil is more than just a byproduct, it helps carry the fish’s flavor across the broth. But it can also be gritty, so I suggest straining it through a fine mesh. This makes the soup cleaner while keeping the taste full. Use it right after sautéing the aromatics for better blending.
Pick the right brand of miso. Some miso pastes are salty, others are sweeter. Choose white miso if you want mildness, or yellow for a fuller profile. I usually stick with white or yellow for a more balanced broth.
Don’t chop your vegetables too early. If you’re prepping ahead, store sliced radish and eggplant in water to keep them from browning. But keep kangkong leaves whole and unwashed until the last minute. This keeps everything fresh and prevents limp, soggy greens.
Add more water only if needed. The 2 quarts in the recipe are split for a reason. Start with 1.5 quarts and only add the rest after the vegetables soften. This helps control the flavor strength and keeps the soup from tasting watered down.
