How to Make (Step-by-Step):

  1. Prep the aromatics: On a sturdy board, gently smash the lemongrass stalks with the flat side of your knife. Cut into manageable lengths. Gather your other veggies and aromatics.
  2. Start the base: Heat the oil in a large pot over medium heat. Add onion, garlic, ginger (or galangal), chilies, and lemongrass. Stir until fragrant and the onion is translucent, about 3–4 minutes.
  3. Build flavor: Toss in kaffir lime leaves, carrot, and bell pepper. Sauté for 2–3 more minutes.
  4. Add liquids: Pour in coconut milk and vegetable broth. Stir in sugar and soy sauce. Bring to a gentle boil.
  5. Simmer: Lower heat and let the soup simmer for 10 minutes so the aromatics infuse their flavor.
  6. Add mushrooms & tofu: Add mushrooms and tofu cubes. Continue to simmer for another 10 minutes, or until all veggies are tender.
  7. Taste and adjust: Add lime juice, salt, and pepper. Taste and tweak for your perfect balance of salty, sour, and sweet.
  8. Finish & serve: Remove lemongrass and lime leaves. Stir in fresh cilantro and green onions. Let rest off the heat for 5 minutes before serving.

Expert Tips:

  • Use the back of a heavy knife to smash the lemongrass and release max flavor.
  • If you can’t find kaffir lime leaves, add an extra squeeze of lime and some zest for brightness.
  • For ultra-creamy soup, use full-fat coconut milk and simmer gently—don’t let it boil vigorously so it won’t split.
  • Prep all vegetables and aromatics ahead for speedier assembly.

Recipe Variations:

  • Vegan Version: Stick with tofu. Swap for vegan fish sauce or extra soy sauce.
  • Protein Boost: Add chicken breast (poached and shredded) or shrimp.
  • Noodle Soup: Toss in rice noodles for a heartier meal.
  • Veggie-packed: Bulk it up with baby corn, snow peas, or bok choy.
  • Spicy Swap: Use a dash of Thai chili paste for more spice.

Storage and Reheating:

Cool leftover soup completely and transfer to an airtight container. Store in the fridge for up to 3 days. Reheat gently on the stove over low heat to avoid curdling the coconut milk. If it thickens, thin with extra broth!

Serving Suggestions:

  • Ladle into bowls and top with extra cilantro, a squeeze of lime, or sliced chilies.
  • Serve with jasmine rice or crusty bread for dipping.
  • Add a side of Thai cucumber salad to balance the richness.
