Bagoong is a Filipino fermented paste made from fish or shrimp mixed with salt and aged for weeks to months. It functions as a condiment and cooking ingredient across Philippine cuisine, delivering an intensely salty, savory, and slightly funky flavor that anchors many traditional dishes. Think of it as the Filipino cousin of Thai shrimp paste or Korean fermented fish sauce, though with a texture and identity all its own.
How Bagoong Is Made
The process is simple in concept but slow in practice. Fresh fish or shrimp are washed, drained, and mixed with salt at ratios ranging from one part salt to three parts seafood up to two parts salt to seven parts seafood. The salt concentration in the finished product typically falls between 15 and 25 percent, which is high enough to prevent harmful bacteria from growing while allowing beneficial fermentation to take place.
Once mixed, the salted seafood goes into jars or large clay pots and sits for several months or longer. During this time, naturally occurring salt-tolerant bacteria break down the proteins in the fish or shrimp, producing the characteristic flavor compounds that give bagoong its complex, cheese-like aroma. Over the course of fermentation, the mixture separates into two layers: a solid paste on the bottom and a liquid on top. That liquid, skimmed off, becomes patis, or Filipino fish sauce. The paste that remains is bagoong.
The Two Main Types
Bagoong Alamang (Shrimp Paste)
This is the most widely recognized variety, made from tiny shrimp or krill. The shrimp are cleaned, drained, dried, and ground before being mixed with salt at roughly 300 grams of salt per kilogram of shrimp. The mixture is bottled, sealed, and left to ferment for at least three weeks, though longer fermentation produces better results. During the waiting period, you stir the jar occasionally so the salt distributes evenly. Bagoong alamang ranges in color from pink to grayish purple depending on the shrimp used and how long it has aged.
Bagoong Isda (Fish Paste)
This version uses whole small fish, most commonly anchovies, though sardines, herring, silverside, slipmouth, and freshwater porgy all appear in regional recipes. Bagoong isda tends to be reddish brown, with a stronger, fishier flavor than its shrimp counterpart. The texture is chunkier since it retains pieces of partially broken-down fish rather than forming a smooth paste. Different regions of the Philippines produce their own variations, including bagoong balayang (from anchovies in Pangasinan) and ginamos (a Visayan version that’s often more pungent and liquid).
What Bagoong Tastes Like
If you’ve never tried it, the aroma hits first. It’s pungent, briny, and slightly cheesy. The taste is intensely salty with a deep umami backbone that lingers. Some versions lean sweeter, especially commercial bagoong alamang that has been sautéed with garlic, onion, and sugar. Raw or uncooked bagoong has a more aggressive, funky edge. The flavor profile works similarly to how anchovy paste or Parmesan cheese functions in Western cooking: you wouldn’t eat a spoonful on its own, but in the right amount it makes everything around it taste more savory and complete.
How Filipinos Use It
Bagoong plays two roles in Filipino cooking. As a condiment, it’s served alongside dishes as a dipping side or flavor booster. The most classic pairing is kare-kare, a peanut-based oxtail stew that tastes flat without a spoonful of bagoong alamang stirred in at the table. It’s also the traditional partner for green mangoes, where the salty-funky paste contrasts sharply with the sour, crisp fruit.
As a cooking ingredient, bagoong goes directly into the pan. Pinakbet, a vegetable stew from the Ilocos region featuring bitter melon, eggplant, squash, and okra, gets its signature depth from bagoong stirred into the broth. Bagoong fried rice is a popular dish where the paste is stir-fried with garlic and rice until every grain picks up color and flavor. Sautéed bagoong with tomatoes and onions becomes a spicy relish eaten with steamed vegetables like water spinach, sweet potato leaves, or okra.
There’s also a cooked, sweetened version of bagoong alamang (sometimes called ginisang bagoong) where the paste is sautéed with garlic, onion, vinegar, and sugar until it becomes a glossy, jammy condiment. This milder preparation is the gateway version for people who find raw bagoong too intense.
Nutritional Profile
Bagoong is a condiment, not a main dish, and its nutritional impact reflects that. It delivers meaningful protein from the fermented seafood, roughly 14 grams in a full-cup serving. But the sodium content is where it demands attention: a single serving can contain over 20,000 milligrams of sodium, which is nearly nine times the recommended daily limit. In practice, people use bagoong in teaspoon-sized amounts, so actual sodium intake per meal is far lower. Still, it’s one of the saltiest condiments in any cuisine, and people managing blood pressure should treat it accordingly.
The fermentation process also generates bioactive compounds. Like other fermented foods, bagoong contains bacteria that partially predigest the seafood proteins, which may make certain nutrients more accessible. However, fermentation also produces histamine, a compound that can cause headaches, flushing, or digestive discomfort in sensitive individuals. Well-made bagoong with proper salt concentrations (around 25 percent) tends to keep histamine levels well within safety limits, typically below the international threshold of 200 milligrams per kilogram of product.
Buying and Storing Bagoong
In Filipino grocery stores and Asian markets, you’ll find bagoong in glass jars or plastic tubs, usually labeled as either “shrimp paste” (alamang) or “fish paste” (isda). Some brands sell it raw, others sell it pre-sautéed and sweetened. The sautéed versions are milder and more approachable for first-time buyers. Color varies widely: pink, reddish-brown, dark purple, or grayish, all normal depending on the type and age.
Unopened, bagoong lasts for months at room temperature thanks to its high salt content. Once opened, refrigeration keeps the flavor stable and prevents further fermentation from shifting the taste. A well-sealed jar in the fridge will last for a year or more. If the paste develops off-colors or an unusually sour smell distinct from its normal pungency, it’s time to replace it.
