Ingredients

  • 4 cups vegetable broth
  • 1 can (13.5 oz) coconut milk (full fat for creaminess)
  • 1 cup firm tofu, cubed
  • 1 stalk lemongrass, cut into 2-inch pieces and smashed
  • 3-4 kaffir lime leaves, torn into pieces
  • 2 slices galangal (or ginger if unavailable)
  • 3-4 Thai bird’s eye chilies, sliced (adjust to taste)
  • 1 cup mushrooms, sliced (shiitake or button mushrooms work well)
  • 1 medium carrot, thinly sliced
  • 1/2 cup cherry tomatoes, halved
  • 1 small onion, thinly sliced
  • 2 tablespoons soy sauce or tamari for gluten-free
  • 1 tablespoon fresh lime juice
  • 1 teaspoon palm sugar or brown sugar
  • Fresh cilantro for garnish
  • Optional: 1/2 cup baby spinach or kale

Equipment

  • Large pot or Dutch oven
  • Sharp knife
  • Cutting board
  • Wooden spoon or ladle
  • Measuring cups and spoons
  • Serving bowls

Instructions

  1. Prepare the aromatics: Rinse the lemongrass stalk and cut it into 2-inch pieces. Smash them with the back of a knife to release the flavor. Tear the kaffir lime leaves into smaller pieces and slice the galangal thinly. Set aside.
  2. Start the broth: In a large pot, combine the vegetable broth, lemongrass, kaffir lime leaves, and galangal. Bring it to a gentle boil over medium heat. Let it simmer for about 10 minutes so the flavors infuse.
  3. Add coconut milk and vegetables: Pour in the coconut milk and stir to combine. Add the sliced mushrooms, carrot, cherry tomatoes, and onion. Reduce the heat to medium-low and cook for 5-7 minutes until the vegetables are tender but still vibrant.
  4. Incorporate tofu and seasoning: Gently fold in the cubed tofu. Add soy sauce, sugar, and sliced chilies. Simmer for another 3-4 minutes to heat through and let the flavors marry.
  5. Finish with lime and greens: Remove the pot from heat. Stir in the fresh lime juice and add baby spinach or kale if using. The residual heat will wilt the greens perfectly.
  6. Adjust seasoning and serve: Taste the soup and adjust the seasoning with more soy sauce or lime juice if necessary. Serve hot, garnished with fresh cilantro leaves.

Tips & Variations

“If you can’t find galangal, fresh ginger is a good substitute, though the flavor will be slightly different. For a spicier kick, add more Thai chilies or a dash of chili paste.”

Here are some ways to personalize your tom kha vegetarian soup:

  • Add other veggies: Bell peppers, baby corn, or zucchini can add extra texture and color.
  • Make it gluten-free: Use tamari instead of soy sauce.
  • For more protein: Try adding edamame or chickpeas along with tofu.
  • Use fresh lime zest: For an extra citrusy aroma, grate a bit of lime zest into the soup just before serving.
  • Make it heartier: Serve over steamed jasmine rice or rice noodles for a filling meal.
