Hot And Sour Soup Thai Recipe

This Hot and Sour Soup recipe stays true to its Thai roots, combining the signature elements of sourness (from tamarind and lime) and heat (from chilies), creating a balanced yet exciting dish. The addition of ingredients like lemongrass, galangal, and fish sauce brings in that unique depth and complexity that defines Thai cuisine.

Ingredients Needed

Here’s what you’ll need for an authentic, mouth-watering Hot and Sour Soup:

• 4 cups chicken stock (or vegetable broth for a vegetarian version)
• 1 cup mushrooms (shiitake or straw mushrooms are best, but any variety works)
• 1-2 Thai bird’s eye chilies, smashed (or more if you like extra heat)
• 1 stalk lemongrass, cut into 3-inch pieces and smashed
• 3-4 slices galangal (substitute with ginger if you can’t find it)
• 1-2 kaffir lime leaves, torn (optional but recommended for the signature fragrance)
• 3 tablespoons fish sauce (for that deep umami flavor)
• 1 tablespoon soy sauce (adds saltiness and depth)
• 2 tablespoons tamarind paste (or 1 tablespoon of tamarind concentrate)
• Juice of 2 limes (to add the fresh, zesty sourness)
• 1-2 tablespoons palm sugar (balances the sourness and heat)
• 1 cup baby tomatoes, halved (for sweetness and color)
• 1 cup tofu, cut into cubes (optional, but a great vegetarian alternative)
• 1/2 cup cilantro leaves, chopped (for garnish)
• 1-2 red Thai chilis, sliced (optional, for extra heat)
• 1/2 cup Thai basil (optional, for extra flavor complexity)

Cooking Instructions

1. Prepare The Broth

   • Start by bringing the chicken stock to a boil in a large pot. If you’re using vegetable broth, the flavor will still be amazing, but chicken stock adds a richness that pairs beautifully with the sour and spicy elements.

2. Add The Aromatics

   • Once the stock is boiling, add the smashed lemongrass, galangal slices, bird’s eye chilies, and kaffir lime leaves. Let this simmer for 10-15 minutes so that all the flavors infuse the broth. This step is crucial for creating the aromatic foundation of the soup.

3. Season The Soup

   • Add the fish sauce, soy sauce, tamarind paste, and palm sugar to the broth. Stir to combine. Taste and adjust for balance. The broth should be a nice balance of salty, sour, and a bit of sweetness. You can adjust the amount of fish sauce or sugar depending on your personal preference.

4. Add The Vegetables

   • Stir in the baby tomatoes and mushrooms, letting them cook in the broth for about 5 minutes until softened. The tomatoes will break down slightly, releasing their juices into the soup for added flavor.

5. Add Protein (Optional)

   • If you’re adding tofu, gently stir it in now. Let the tofu warm through for another 5-7 minutes. You can also add shrimp, chicken, or any other protein at this stage if you like.

6. Final Touches

   • Once the soup has simmered and everything is well-combined, remove it from heat. Stir in the lime juice, adjusting the acidity level to your liking. Taste the broth and tweak the seasoning as necessary-if it’s too sour, add a little more sugar; if it’s too sweet, add a splash more fish sauce or lime juice.

7. Serve

   • Ladle the soup into bowls, and garnish with fresh cilantro, Thai basil, and extra chilies for a pop of color and flavor. Serve immediately and enjoy!

Ingredient Insights

• Tamarind Paste: The secret ingredient that gives this soup its signature sour profile. Tamarind is a fruit that’s both sweet and tangy, and in soup, it provides a complex sourness that’s different from the acidity of lime juice.
• Lemongrass: This fragrant herb imparts a citrusy aroma that’s very distinct in Thai cooking. It’s essential to give the soup that fresh, bright flavor that balances the richness of the broth.
• Galangal: Often confused with ginger, galangal has a more peppery, citrusy taste and is commonly used in Southeast Asian cuisine. It’s an essential element of the soup base.
• Fish Sauce: This salty, umami-rich liquid is a cornerstone of Thai cooking. It’s made from fermented fish, and while its aroma may be strong, it brings a deep, savory richness to the soup that can’t be replaced.

Expert Tips

• Balancing Heat and Sourness: One of the key challenges in making Hot and Sour Soup is getting the right balance between heat, sourness, and sweetness. Start by tasting the broth as you go, and don’t be afraid to adjust. Add extra sugar if it’s too sour, or more lime juice if it’s too sweet.
• Use Fresh Herbs: Fresh cilantro and Thai basil are critical for enhancing the soup’s aroma and flavor. If you don’t have access to Thai basil, regular basil can work in a pinch, but it’s definitely worth seeking out the authentic variety.
• Control the Spice Level: If you’re not a fan of intense heat, start with just one bird’s eye chili and remove it once the soup is done simmering. You can also remove the seeds from the chili to lessen the heat.
• Simmer the Broth Slowly: Allow the aromatics (lemongrass, galangal, and kaffir lime leaves) to infuse the broth for at least 10-15 minutes. This step is crucial for building the depth of flavor.

Recipe Variations

• Vegetarian Version: You can easily make this soup vegetarian by using vegetable broth, omitting the fish sauce or replacing it with soy sauce, and adding extra vegetables or tofu for protein.
• Spicy Option: If you love heat, try adding extra chilies, or even a dash of chili paste for an extra kick.
• Seafood Version: Swap the tofu for shrimp or crab for a more luxurious version of the soup. Add them in the last few minutes of cooking so they don’t overcook.
• Coconut Milk: For a creamier, more decadent soup, add a splash of coconut milk toward the end of cooking. It adds richness and mellows the heat and sourness.

Final Words

Hot and Sour Soup is truly a flavor-packed adventure in a bowl. It brings together a variety of textures and tastes, from the hearty mushrooms and tofu to the vibrant, fresh herbs and the tangy, spicy broth. The combination of heat and sourness is something that sets this dish apart, creating a balance that feels both refreshing and comforting.

Making this soup at home means you can tailor it to your own tastes, adjusting the level of heat and sourness, and making it as bold or as mild as you prefer. It’s the kind of dish that’s perfect for impressing guests, or simply indulging in a delicious, homemade Thai meal.
