Sinigang na Isda sa Miso is a delightful Filipino soup that combines the tangy flavors of traditional sinigang with the rich umami of miso paste. This dish is perfect for those who love a hearty and comforting meal, featuring tender fish fillets and a medley of fresh vegetables.
Some ingredients in this recipe might not be commonly found in every household. Miso paste is a fermented soybean paste that adds a unique depth of flavor and can be found in the Asian section of most supermarkets. Kangkong or water spinach is a leafy green vegetable often used in Asian cuisine; if unavailable, regular spinach can be a good substitute. Green chili peppers add a mild heat to the dish and can be found in the produce section.

Fish fillets: Use your favorite type of fish fillets, such as tilapia, bangus (milkfish), or any white fish.
Miso paste: A fermented soybean paste that adds a rich, umami flavor to the soup.
Onion: Adds sweetness and depth to the broth.
Tomatoes: Provide a tangy base for the soup.

Technique Tip for This Recipe
When sautéing the onions and tomatoes, make sure to cook them until they are fully softened and slightly caramelized.

Additionally, when dissolving the miso paste in boiling water, whisk it thoroughly to ensure it is fully incorporated and there are no lumps. This will give your broth a smooth and consistent texture.

How to Store or Freeze This Dish
Allow the sinigang na isda sa miso to cool to room temperature before storing. This helps prevent condensation, which can lead to soggy vegetables and a diluted broth.
Transfer the sinigang to an airtight container. Make sure the container is large enough to hold the fish fillets, vegetables, and broth without squishing the ingredients.
Store the container in the refrigerator if you plan to consume the sinigang within 3-4 days. The flavors will meld together, making the dish even more delicious over time.
For longer storage, place the airtight container in the freezer. The sinigang can be frozen for up to 2 months. Label the container with the date to keep track of its freshness.
When ready to reheat, thaw the sinigang in the refrigerator overnight if frozen. This gradual thawing helps maintain the texture of the fish fillets and vegetables.
Reheat the sinigang on the stovetop over medium heat. Stir occasionally to ensure even heating. Avoid boiling, as this can overcook the fish and make the vegetables mushy.
If the broth has thickened after refrigeration or freezing, add a bit of water or vegetable broth to reach the desired consistency. Adjust the seasoning with salt and pepper if needed.
Enjoy your reheated sinigang na isda sa miso as if it were freshly made, savoring the harmonious blend of miso, fish, and vegetables.
