Bangus sa tausi is a popular Filipino dish featuring bangus (milkfish) cooked in a savory black soybean sauce known as tausi. This dish blends Filipino and Chinese culinary influences, combining the rich flavors of milkfish with the salty, umami taste of fermented black beans.

The preparation begins by frying fish, then sautéing garlic, onions, and ginger and adding tomatoes, tausi, and fish sauce, which create the dish's distinctive flavor. The bangus is then simmered in the mixture, absorbing the rich sauce. Typically served with steamed white rice, bangus sa tausi is a hearty and satisfying meal with a balance of tender fish and a savory, slightly salty sauce.
