Ingredients
Scale
- 4 cups chicken or vegetable broth
- 1 stalk lemongrass, bruised and cut into 2-inch pieces
- 1-inch piece galangal, thinly sliced (or ginger if unavailable)
- 4–5 kaffir lime leaves, torn
- 2–3 small red chilies (bird's eye chilies), crushed (adjust to taste)
- 1 lb raw shrimp, peeled and deveined, tails on or off
- 8 oz straw mushrooms or button mushrooms, halved
- 2 tbsp fish sauce
- 2 tbsp lime juice, freshly squeezed
- 1 tsp granulated sugar (optional, to balance flavors)
- 1/4 cup chopped fresh cilantro, for garnish
- 1/4 cup chopped green onions, for garnish (optional)
- Chili oil or roasted chili paste (nahm prik pao), for serving (optional)
Instructions
- In a medium pot, bring the chicken or vegetable broth to a boil over medium-high heat.
- Add the bruised lemongrass, sliced galangal, torn kaffir lime leaves, and crushed red chilies to the boiling broth. Reduce heat to medium-low and simmer for 5-7 minutes to allow the flavors to infuse.
- Remove the lemongrass, galangal, and kaffir lime leaves from the broth using a slotted spoon. This prevents them from being chewy while eating, but their flavor has already been extracted.
- Add the shrimp and mushrooms to the simmering broth. Cook for 2-3 minutes, or until the shrimp turn pink and are cooked through. Be careful not to overcook the shrimp.
- Remove the pot from the heat. Stir in the fish sauce, fresh lime juice, and sugar (if using). Taste and adjust seasonings as needed; you may want more fish sauce for saltiness, lime juice for sourness, or chilies for heat.
- Ladle the hot soup into serving bowls. Garnish generously with fresh cilantro and green onions.
- Serve immediately, optionally with a side of chili oil or roasted chili paste for an extra kick.
Notes
For an even richer flavor, you can use shrimp shells to make your own shrimp broth. Add a splash of coconut milk for a creamier, milder version (Tom Yum Goong Nam Khon).
