Ingredients

Equipment

• Large soup pot or Dutch oven
• Sharp knife and cutting board
• Wooden spoon or ladle
• Fine mesh strainer or slotted spoon
• Measuring cups and spoons
• Tofu press or heavy plate (optional, for pressing tofu)
• Serving bowls

Instructions

1. Prepare the aromatics:
   • Trim the lemongrass stalks, remove outer layers, and cut into 2-inch pieces. Bruise them by whacking with the back of your knife to release flavor.
   • Slice the galangal thinly. If using ginger, peel and slice.
   • Tear the kaffir lime leaves to help release their oils.
2. Make the soup base:
   • In your large pot over medium heat, add vegetable broth, lemongrass, galangal, kaffir lime leaves, chilies, and onion. Bring to a gentle simmer.
   • Let it cook for 10 minutes to infuse the broth with the aromatics.
3. Add the vegetables and tofu:
   • Add the mushrooms, carrots, and tofu cubes to the simmering broth. Cook for 5 minutes.
   • Stir in the cherry tomatoes and cook for 2 minutes more.
4. Pour in the coconut milk:
   • Add the two cans of coconut milk, stirring gently. Bring just to a gentle simmer—do not boil, as coconut milk can split.
5. Season the soup:
   • Add soy sauce, coconut sugar, and salt to taste. Adjust chilies for heat. Simmer for 5-7 minutes, letting flavors meld.
6. Finish with lime juice and garnishes:
   • Remove the lemongrass, galangal slices, and kaffir lime leaves with a slotted spoon or strainer.
   • Stir in fresh lime juice (start with 2 tbsp, taste, and add more as needed).
   • Ladle into serving bowls and garnish with cilantro and scallions.
7. Serve hot and enjoy!
   • Enjoy your vegetarian Tom Kha as a starter or main course. Serve with steamed jasmine rice for a heartier meal.

Tips & Variations

• Can’t find galangal or kaffir lime leaves?
  • Galangal can be swapped for fresh ginger, and lime leaves can be replaced with extra lime zest and juice for brightness.
• Make it vegan:
  • This recipe is naturally vegan. For a soy-free version, use chickpea tofu or tempeh and coconut aminos instead of soy sauce.
• Spice level:
  • Control the heat by adjusting the number of Thai chilies. For a milder soup, remove seeds or use only one chili.
• Add more veggies:
  • Bok choy, baby corn, snow peas, or bamboo shoots make excellent additions.
• Protein boost:
  • Swap tofu for tempeh, or add a handful of edamame for extra protein.
• Storage:
  • Leftovers keep well for up to 3 days in the fridge. Reheat gently to preserve the coconut milk’s texture.

“For the most aromatic soup, use fresh lemongrass and galangal—these classic Thai ingredients truly make all the difference!”
