Ingredients

For the soup:

• 4 cups shrimp stock or unsalted chicken stock
• 12–15 medium or large shrimp, shell-on and head-on if possible
• 2 stalks lemongrass, smashed and cut into 2-inch pieces
• 6 makrut lime leaves, torn into pieces
• 8 slices galangal
• 2–5 Thai chilies, minced or crushed
• 7 ounces oyster mushrooms, torn into bite-sized pieces
• 1/4 cup Thai chili paste
• 3 tablespoons fish sauce
• 1/2 cup fresh lime juice
• 1 teaspoon sugar
• Fresh cilantro, chopped for garnish
• Jasmine rice for serving

For the shrimp stock:

• Shrimp shells and heads
• 1 tablespoon neutral oil
• 4 1/4 cups water
• 1/4 cup finely chopped onion
• 1/4 cup finely chopped daikon (optional)

Directions

1. Begin by preparing the shrimp stock. Peel and devein the shrimp, reserving the shells and heads. Set the shrimp aside.
2. Heat the oil in a stock pot over medium-high heat. Add the shrimp shells, shrimp heads, onion, and daikon. Sauté for several minutes, pressing the shrimp heads gently to release their rich flavor.
3. Once the shells turn orange and aromatic, pour in the water. Bring to a simmer and cook for 5 minutes.
4. Strain out the shells and solids, keeping 4 cups of stock for the soup.
5. In a large pot, add the shrimp stock, lemongrass, galangal, Thai chilies, mushrooms, and torn makrut lime leaves.
6. Bring the soup to a gentle simmer and cook for about 5 minutes so the herbs infuse the broth with flavor.
7. In a small bowl, loosen the Thai chili paste with a little hot broth, then stir it back into the soup.
8. Add the fish sauce and bring the soup to a light boil.
9. Add the shrimp and cook for 30–50 seconds until they are nearly cooked through. Turn off the heat and allow the residual heat to finish cooking the shrimp.
10. Stir in the fresh lime juice and sugar. Taste and adjust seasoning as needed. The soup should taste boldly sour, slightly spicy, and savory.
11. Garnish with chopped cilantro and serve hot with jasmine rice.

Storage/Reheating

Store leftover Tom Yum Soup in an airtight container in the refrigerator for up to 3 days. For best flavor, keep the shrimp separate if possible to avoid overcooking during reheating.

To reheat, warm the soup gently over medium heat until hot but not boiling. Avoid prolonged boiling after adding lime juice, as it can dull the fresh flavor. If reheating from frozen, thaw overnight in the refrigerator before warming.

You can also freeze the broth separately for up to 2 months. Add fresh shrimp and lime juice when serving for the best taste.
