Dietary Info: Low FODMAP • Dairy-Free • Gluten-Free • Paleo-Friendly

Soup Base

1 can (14 oz / 400 mL) full-fat coconut milk (check label for no inulin/chicory — Aroy-D or Native Forest Simple are good)
2 cups (480 mL) low-FODMAP chicken broth (no onion or garlic; Fody or Massel 7’s recommended)
1-inch piece fresh ginger, peeled and thinly sliced
Optional: add a few slices of lemongrass stalk or 1 kaffir lime leaf for authentic flavor (remove before serving — both are FODMAP-safe).

Protein

1 lb (450 g) shrimp (peeled & deveined) or thinly sliced chicken breast

Vegetables

1 cup oyster mushrooms or 1 cup canned bamboo shoots, drained
(Oyster mushrooms are low FODMAP; other mushrooms like white/button are high FODMAP.)
½ cup chopped carrots or red bell pepper (adds color & nutrients — both low FODMAP)

Seasonings & Flavor

2 tbsp fresh lime juice
1 tbsp fish sauce (check label for no garlic/onion; Red Boat brand is safe)
1 tsp low-FODMAP chili paste or sriracha (check ingredients; Fody Thai Red Curry Paste or Sky Valley Sriracha are usually OK)
½ tsp salt, or to taste

Garnish

Make the base:
In a large pot, combine coconut milk, chicken broth, and ginger slices. (Add lemongrass or lime leaf if using.) Bring to a gentle boil over medium heat.
Add protein & veggies:
Add shrimp or chicken, oyster mushrooms, and carrots/peppers.
Cook for 5–8 minutes, until shrimp turns pink or chicken is cooked through.
Season the soup:
Reduce heat to low. Stir in lime juice, fish sauce, chili paste, and salt. Taste and adjust seasoning — add a bit more lime or fish sauce as you like.
Finish & serve:
Remove ginger (and lemongrass/lime leaf if used).
Ladle into bowls and garnish with cilantro and scallion tops.
Serve hot with lime wedges on the side.
