Ingredients
Seafood
- 20 oz whole shrimps (with heads and shells)
Broth Base
- 3 stalks lemongrass (minced, or 3 tablespoons lemongrass paste if fresh is unavailable)
- 4 Thai bird’s eye chilies (smashed; Serrano chilies or red pepper flakes as substitutes)
- 6 garlic cloves (smashed)
- 10 kaffir lime leaves (torn)
- 1 piece galangal (sliced; fresh ginger can be substituted)
- 1 cup low sodium chicken broth
- 5 cups water
Vegetables & Herbs
- 1 medium onion (cut into ½ inch thick wedges)
- 8 oz oyster mushrooms (sliced)
- 2 tomatoes (cut into wedges)
- ½ cup fresh coriander/cilantro leaves (for garnish)
Seasonings & Others
- 2 tsp sugar
- 6 tbsp fish sauce
- 5 tbsp lime juice
- 3 tbsp Thai roasted chili paste
- ⅔ cup coconut milk
Instructions
- Prepare Shrimp: Remove the shells and heads from the shrimp carefully, reserving the shells and heads to enhance the broth flavor. Set the peeled shrimp meat aside for later use.
- Make Broth: In a large pot, combine the reserved shrimp heads and shells with minced lemongrass, smashed Thai bird’s eye chilies, garlic, torn kaffir lime leaves, sliced galangal, chicken broth, and water.
- Simmer Broth: Bring this mixture to a boil, then reduce the heat and let it simmer gently for 10 minutes. This process extracts deep flavors from the shrimp shells and aromatic herbs.
- Strain Broth: Carefully pour the broth through a fine strainer to remove all solids, keeping the clear, fragrant liquid for the soup base.
- Cook Vegetables: Return the strained broth to the pot. Add the onion wedges and sliced oyster mushrooms, simmering them for about 3 minutes until tender.
- Add Tomatoes: Stir in the tomato wedges and cook for an additional minute, allowing them to soften slightly and release their juices.
- Cook Shrimp: Add the peeled shrimp meat to the pot and cook for 2 minutes or until the shrimp turns pink and opaque, indicating it is cooked through.
- Season Soup: Mix in the sugar, fish sauce, Thai roasted chili paste, coconut milk, and lime juice. Stir well and simmer for 1 more minute to blend all flavors harmoniously.
- Serve: Ladle the hot soup into bowls, garnish with fresh coriander leaves, and serve immediately to enjoy the authentic Thai flavors.
Notes
- You can substitute galangal with fresh ginger but expect a slightly different flavor profile.
- Adjust chili quantity according to your spice tolerance; Thai bird’s eye chilies are very spicy.
- Using shrimp shells and heads in the broth adds richness and depth to the soup.
- Lemongrass paste is a convenient alternative if fresh lemongrass stalks are unavailable.
- Ensure not to overcook the shrimp to maintain a tender texture.
