4 cups shrimp stock (or unsalted chicken stock)

12 medium shrimp, head-on and shell-on (if making shrimp stock)

2 stalks lemongrass (bottom half only), smashed and cut into 2-inch pieces

6 makrut lime leaves

8 slices galangal

25 Thai chilies, smashed and cut into large pieces (adjust to taste)

3 cups oyster mushrooms, torn into bite-sized pieces

1/4 cup Thai chili paste

1 tablespoon neutral oil

4 1/4 cups water

1/4 cup chopped onion (optional)

  1. Heat oil in a pot over medium heat. Add shrimp shells, heads, and onion (if using); sauté until fragrant and shells turn pink, 3-5 minutes.

  2. Add water, bring to boil, then simmer gently 20-25 minutes. Strain and discard solids.

Prepare the Soup:

  2. Add oyster mushrooms; cook 3-4 minutes until tender.

  3. Stir in chili paste, fish sauce, lime juice, and sugar; adjust seasoning.

  4. Add shrimp; cook 2-3 minutes until pink and opaque.

  5. Remove lemongrass, lime leaves, and galangal slices.

Notes

Substitute chicken or vegetable stock if shrimp stock is unavailable.

Use shiitake or button mushrooms instead of oyster mushrooms.

Adjust spiciness with more or fewer Thai chilies.

Add fresh herbs like Thai basil or mint for extra aroma.

Use peeled shrimp for easier eating.
