Fish amok is one of Cambodia’s signature dishes: delicate fish gently set in a fragrant coconut custard scented with lemongrass, galangal, turmeric, and kaffir lime.
A quick homemade kroeung-style paste flavors the coconut mixture, while a gentle steam keeps the fish moist and the custard tender.

Steam the amok gently and stop as soon as the custard is set. A hard boil can split the coconut mixture and toughen the fish.
Serving Suggestions
Serve in banana-leaf cups with steamed jasmine rice, sliced chilies, and extra kaffir lime leaves or cilantro.

Recipe Notes
Cod, halibut, or snapper all work well. Assemble the cups several hours ahead, refrigerate, and steam just before serving.

Cambodian Fish Amok with Coconut Custard
Equipment
- Steamer
- Food processor
- Mixing bowl
- Four small ramekins or banana-leaf cups
- Chef’s knife
Ingredients
Fish and Custard
- 1 lb firm white fish fillets cut into bite-size pieces
- 1 cup coconut milk full fat
- 2 large eggs beaten
- 1 tbsp fish sauce
- 1 tbsp rice flour
- 1 tsp palm sugar or brown sugar
Kroeung Paste and Serving
- 2 stalks lemongrass tender centers sliced
- 4 cloves garlic
- 1 tbsp fresh galangal chopped
- 1 tsp ground turmeric
- 4 leaves kaffir lime leaves finely sliced
- 4 pieces banana leaves or ramekins for steaming
- 2 cups cooked jasmine rice for serving
Instructions
Make the Paste:
- Blend the lemongrass, garlic, galangal, turmeric, and half the kaffir lime leaves with a splash of water until a coarse paste forms.
- Whisk the coconut milk, eggs, fish sauce, rice flour, palm sugar, and paste in a bowl until smooth.
Assemble the Amok:
- Line four small banana-leaf cups or ramekins with the remaining lime leaves. Divide the fish among them.
- Pour the coconut custard over the fish, leaving a little room at the top.
Steam and Serve:
- Arrange the cups in a steamer. Cover and steam gently until the custard is just set and the fish flakes easily, 18 to 22 minutes.
- Serve immediately with jasmine rice and a few fresh herbs or sliced chilies.
Notes
- Use full-fat coconut milk for a smooth custard.
- Gentle steaming keeps the custard from splitting.
- Prepare the cups ahead but steam close to serving time.
