Tomato Fish Fillet Soup | Tangy, Savory & Tender

Tomato Fish Fillet Soup is a classic home-style soup. The fish fillets are tender and boneless, while the tomatoes are cooked down into a rich, tangy broth. Every sip of soup and every bite of fish warms you from the inside out. It’s perfect when you have no appetite or want something light and refreshing.

🌴 Ingredients:

· 200g fish fillets (snakehead, sole, or basa, thinly sliced, boneless)
· 2 tomatoes (ripe, for a richer broth)
· 1 egg (use egg white only, for marinating the fish)

🌴 Aromatics:

· A small piece of ginger (minced)
· 3-4 cloves garlic (minced)
· 1 stalk scallion (chopped, for garnish)
· Cilantro, to taste (cut into sections, for garnish, optional)

🌴 Seasonings:

· 1 tbsp ketchup (about 15g, for color and tang)
· 1 tbsp cooking wine (about 10ml, for marinating)
· 1 tsp cornstarch (about 5g, for marinating, locks in moisture)
· 1/2 egg white (for marinating, makes it tender)
· 3g salt (about a teaspoon, divided)
· A pinch of white pepper powder
· Cooking oil, as needed

🌴 Instructions:

  1. Marinate the Fish
    Wash and drain the fish fillets. Add the cooking wine, half an egg white, cornstarch, a pinch of salt, and white pepper. Mix well and marinate for 15 minutes. ⚠️ Note: This keeps the fish tender and prevents it from breaking apart. I’ve tried cooking it without marinating, and it fell apart into a mushy mess.
  2. Prepare the Tomatoes
    Score a cross on the top of each tomato and blanch in boiling water for 1 minute. Peel and cut into small pieces. ⚠️ Note: Peeling the tomatoes makes the broth richer and smoother. I’ve tried leaving the skin on, and the soup was full of curled tomato skins.
  3. Cook the Tomatoes
    Heat oil in a pan, add the minced ginger and garlic, and stir-fry over low heat until fragrant. Add the tomato pieces and stir-fry over medium heat until they release their juice and red oil. Add the ketchup and a pinch of salt. ⚠️ Note: Make sure to cook the tomatoes until they release their juice for a rich broth. I’ve tried adding water too early, and the soup tasted bland.
  4. Simmer the Broth
    Add plenty of hot water and bring to a boil. ⚠️ Note: Always use hot water; cold water will lock in the sourness and make the soup taste flat.
  5. Add the Fish
    Keep the heat high. Add the marinated fish slices one by one, gently separating them with chopsticks. Cook for 1-2 minutes until they change color and curl slightly. ⚠️ Note: Add the fish last and cook for only 1-2 minutes, or it will fall apart. I’ve tried dumping it all in at once, and it clumped together, raw on the inside.
  6. Season and Serve
    Add salt to taste and a pinch of white pepper. Turn off the heat, sprinkle with scallion and cilantro, and serve hot. ⚠️ Note: Add salt at the very end to keep the soup fresh. The fish is already marinated with salt, so taste before adding more.
