  • Allergy-friendly: This recipe is naturally gluten-free and can be made soy-free by using tamari or coconut aminos instead of soy sauce.

Ingredients

  • 4 cups vegetable broth (preferably low sodium)
  • 2 stalks lemongrass, trimmed and smashed
  • 3-4 kaffir lime leaves, torn
  • 3 slices galangal or ginger
  • 2-3 Thai red chilies, smashed (adjust to taste)
  • 200 grams mixed mushrooms (shiitake, oyster, button), sliced
  • 1 medium tomato, cut into wedges
  • 100 grams firm tofu, cubed (optional)
  • 2 tbsp lime juice (freshly squeezed)
  • 1 tbsp soy sauce or tamari (for soy-free option)
  • 1 tsp palm sugar or brown sugar
  • 2 cloves garlic, minced
  • 1 small onion, sliced
  • Fresh cilantro for garnish
  • Spring onions sliced for garnish
  • Optional: 1/2 cup baby corn or other veggies of choice

Equipment

  • Medium soup pot or saucepan
  • Sharp knife and cutting board
  • Ladle
  • Measuring spoons and cups
  • Wooden spoon or spatula
  • Serving bowls

Instructions

  1. Prepare the broth base: In your soup pot, add the vegetable broth along with the smashed lemongrass stalks, torn kaffir lime leaves, and galangal slices. Bring to a gentle boil over medium heat.
  2. Infuse the flavors: Let the broth simmer for about 10 minutes so the aromatic herbs release their flavors. This step is crucial for authentic tom yum taste.
  3. Add the aromatics: Add the minced garlic, sliced onion, and smashed Thai chilies to the broth. Simmer for another 3-5 minutes, adjusting the heat if you want it spicier or milder.
  4. Add vegetables and tofu: Toss in the sliced mushrooms, tomato wedges, and optional baby corn or other vegetables. If using tofu, add the cubed tofu now. Cook for 5-7 minutes until the mushrooms are tender and the vegetables are heated through.
  5. Season the soup: Stir in the soy sauce, lime juice, and palm sugar. Taste and adjust seasoning as needed – you want a balanced sour, salty, and slightly sweet flavor.
  6. Remove herbs: Take out the lemongrass stalks, kaffir lime leaves, and galangal slices before serving to avoid any tough bites.
  7. Garnish and serve: Ladle the soup into bowls and garnish with fresh cilantro and spring onions. Serve hot, accompanied by steamed jasmine rice if desired for a fuller meal.

Tips & Variations

“For the best tom yum, always use fresh herbs. If you can’t find kaffir lime leaves or galangal, dried versions work in a pinch but fresh will give your soup that unmistakable brightness.”

  • Adjust spice levels: If you prefer milder soup, reduce the number of Thai chilies or remove their seeds before adding.
  • Protein boost: Add tempeh or seitan cubes for extra protein instead of tofu.
  • Make it creamy: For a tom yum goong-inspired creamy version, stir in 1/2 cup coconut milk at the end of cooking.
  • Use vegetable stock cubes: If you don’t have homemade broth, vegetable stock cubes dissolved in water work fine.
  • Explore other veggies: Try adding baby bok choy, snap peas, or zucchini for variety and texture.
  • Serve as a starter: This soup makes a great appetizer for Thai-themed dinners or with dishes like Vegetarian Middle Eastern Recipes for Easy, Flavorful Meals.
