This Thai Hot and Sour Fish Soup recipe is heavenly with mushrooms, tomatoes, onions and spices and comes together in 20 minutes for a delicious meal!

I adore Thai cooking because nearly everything is very quick to put together. Once you get down the basic methods of cooking a stir-fry, a curry, fried rice, and soup, you can adjust recipes to your own preferences and explore your own combinations.

Many soup recipes call for a slow simmer for what seems like hours, but Thai soups are flavored with fresh spices which brighten up a broth in a matter of minutes rather than hours.

While this Thai Hot and Sour Fish Soup recipe calls for a few non-Western ingredients, I’ve included substitutes below so those that may not be near a grocery store with access to wild lime leaves, galangal root, or sweet Thai basil can still make this soup.

For those following a vegan or vegetarian diet, this soup is also fabulous when made with vegetable broth and extra vegetables substituted for the fish. Try carrots, bok choy, or bell peppers!

Just make sure that you have 1 or 2 of these beautiful Thai chili peppers.

The husband and I took a trip to Thailand back in 2011.

It was such an incredible trip – the main reason why I wanted to travel there was to try the food.

It completely opened my world to new flavors and experiences, and I love Thai food now more than ever.

As with most Thai cooking, be sure to prep all of your ingredients before you get started. The dish comes together so quickly you won’t have much time to dice or chop once you start.

  • Classic Zester/Grate


  • 6 cups chicken broth
  • 12 ounce about 2 filets of white fish, cut into bite-size chunks (I've had good success with Tilapia, which is cheap and holds up well in the freezer)
  • 1 Tbsp. galangal root - cut into think matchstick (ginger root* works as a substitute)
  • 2 stalks lemongrass** - smashed and chopped into inch-long pieces
  • 2 wild lime leaves - substitute juice from half of one lime if you do not have access to lime leaves
  • 2 small tomatoes - quartered
  • 1/2 cup mushroom - button or white, quartered
  • 2 green onions - chopped
  • 4 tablespoons fresh cilantro - roughly chopped
  • 2 Tbsp. fresh sweet Thai basil leaves - chopped (substitute regular basil if needed - you can also omit if you don't have any handy)
  • 1 tablespoon fish sauce - Sorry, no substitutes! You can find this in almost any grocery store in the Asian foods aisle. It is called for in the majority of Thai dishes, so it is a great pantry staple. The Red Boat brand has a paleo-friendly version.
  • 1-2 hot Thai chili peppers*** to your taste - seeded and sliced into rings
  • Juice from half of one lime

  • Bring the chicken broth, galangal (or ginger) root, lemongrass, and hot Thai pepper to a boil in a heavy pot over medium-high heat.
  • Stir in the fish sauce, mushrooms, basil, lime leaves (or juice, if substituting), and tomatoes, then reduce heat to medium-low. Let it simmer for about ten minutes.
  • Meanwhile, in your serving bowl (or divide among individual soup bowls), place the cilantro, green onions, and lime juice, and give the bowl a little swirl.
  • Add the chunks of fish and continue to simmer until the fish is opaque and cooked through (just a few minutes).
  • Remove the lemongrass stalks and lime leaves, and discard.
  • Transfer the soup to your serving dish (or individual bowls). The cilantro and green onions will rise to the top and maintain their fresh flavors.


Did you know that the easiest way to remove ginger peel is with a spoon? Seriously, give it a try. I peel mine once I buy it, then freeze it. I use my microplane zester to grate the frozen ginger directly into my dishes.
** You can usually find lemongrass among the other spices in your produce section. It freezes nicely if you have extra left in your pack!
*** I buy these peppers by the handful and keep them in my freezer. They are so small that they thaw in just minutes. Be sure to wash your hands thoroughly after handling them and avoid contact with your eyes!
To store this Tilapia Soup, place it in an airtight container in the refrigerator, where it will remain good for up to 3 days. Freezing is possible, but it's best to remove the fish before freezing to avoid a rubbery texture upon reheating.
To reheat, thaw in the fridge if frozen, then gently warm on the stove over low heat until heated through. Avoid boiling to preserve the soup's texture and flavors.
