  • 1 stalk lemongrass, smashed and chopped (optional but recommended)
  • 1 red chili, sliced (adjust to taste)
  • 4 cups vegetable broth
  • 1 can (14 oz) coconut milk
  • 1 medium carrot, thinly sliced
  • 1 cup mushrooms, sliced (shiitake or button mushrooms work well)
  • 1 red bell pepper, julienned
  • 1 cup green beans, trimmed and cut into 2-inch pieces
  • 1 cup baby corn, halved
  • 1 cup tofu, cubed (optional for added protein)
  • 2 tablespoons soy sauce or tamari for gluten-free
  • 1 tablespoon fresh lime juice
  • 2 teaspoons brown sugar
  • Fresh cilantro, chopped, for garnish
  • Fresh Thai basil, optional, for garnish
  • Salt and pepper, to taste

Equipment

  • Large pot or Dutch oven
  • Cutting board
  • Sharp knife
  • Measuring spoons and cups
  • Wooden spoon or spatula
  • Ladle for serving
  • Optional: mortar and pestle (for crushing lemongrass or chili)

Instructions

  1. Prepare your ingredients: Wash and chop all vegetables as described. If using lemongrass, remove the tough outer layers and smash the stalk to release the flavor, then chop into smaller pieces.
  2. Heat the oil: In your large pot or Dutch oven, warm the vegetable oil over medium heat. Add the chopped onion and sauté for about 3-4 minutes until translucent and fragrant.
  3. Add garlic, ginger, lemongrass, and chili: Stir these aromatics into the pot and cook for another 2 minutes, stirring frequently to avoid burning. This step builds the foundational flavors.
  4. Pour in vegetable broth and coconut milk: Add the broth and coconut milk to the pot. Stir well to combine all the flavors.
  5. Add the vegetables: Add the carrot slices, mushrooms, bell pepper, green beans, and baby corn. Bring the soup to a gentle boil, then reduce the heat and let it simmer for 10-12 minutes, or until the vegetables are tender but still crisp.
  6. Add tofu and seasonings: If using tofu, add the cubes now. Stir in the soy sauce, lime juice, and brown sugar. Simmer for an additional 3-4 minutes to let the flavors meld together. Taste and adjust seasoning with salt and pepper as needed.
  7. Remove lemongrass: Before serving, carefully fish out the lemongrass pieces as they are tough and not ideal to eat.
  8. Serve and garnish: Ladle the hot soup into bowls and garnish with fresh cilantro and Thai basil for an extra burst of flavor and color.

Tips & Variations

“To deepen the soup’s flavor, try roasting your vegetables before adding them, or add a splash of tamarind paste for a tangy twist.”

  • Add protein: For a heartier meal, include cubed tofu, tempeh, or chickpeas.
  • Vegetable swaps: Use zucchini, spinach, bok choy, or snap peas based on what’s in season or your preference.
  • Make it spicier: Increase the amount of fresh chili or add a dash of homemade chili powder.
  • For extra umami: Stir in a teaspoon of miso paste at the end of cooking.
  • Gluten-free option: Ensure your soy sauce is gluten-free or use tamari.
