Ingredients (Serves 4)
For the Fish
- 4 firm white fish fillets (cod, snapper, halibut, or sea bass)
- Salt and freshly ground black pepper
- 1 tablespoon lime juice
For the Coconut Broth
- 1 tablespoon coconut oil (or neutral oil)
- 1 small onion, finely sliced
- 3 garlic cloves, minced
- 1 tablespoon fresh ginger, grated
- 1 red chili, thinly sliced (optional for heat)
- 1 tablespoon red curry paste
- 400 ml (1 can) full-fat coconut milk
- 250 ml (1 cup) vegetable or fish stock
- 1 tablespoon fish sauce
- 1 teaspoon brown sugar
- Zest of 1 lime
- 1 tablespoon lime juice (plus extra to taste)
Vegetables (Optional but Recommended)
- 1 red bell pepper, sliced
- 1 cup snap peas or green beans
- 1 small carrot, julienned
- A handful of cherry tomatoes
To Finish
- Fresh cilantro, chopped
- Fresh basil or Thai basil
- Sliced scallions
- Extra chili slices
- Steamed jasmine rice or rice noodles
Step 1: Prepare the Fish
Pat the fish fillets dry with paper towels. Season both sides lightly with salt and black pepper. Drizzle with a little lime juice and set aside while you prepare the broth.
Choose firm fish that can withstand gentle simmering without falling apart. Cod and snapper work beautifully, but sea bass also adds a slightly richer flavor.
Step 2: Build the Aromatic Base
Place a large deep skillet or Dutch oven over medium heat. Add coconut oil and allow it to melt.
Add the sliced onion and sauté for about 3–4 minutes until soft and translucent. Stir in the garlic, ginger, and sliced chili. Cook for another minute until fragrant.
Add the red curry paste and cook it in the oil for 1–2 minutes. This step is important—it “blooms” the spices and deepens the flavor of the dish.
Your kitchen should now smell absolutely incredible.
Step 3: Create the Coconut Broth
Pour in the coconut milk and stock, stirring well to combine with the curry paste mixture. Add fish sauce, brown sugar, and lime zest.
Bring the mixture to a gentle simmer—not a rolling boil. Coconut milk can separate if boiled too aggressively, so keep the heat moderate.
Taste the broth at this stage. It should be slightly sweet, salty, and fragrant. Adjust seasoning if necessary.
Step 4: Add the Vegetables
If using vegetables, add the bell peppers, carrots, and green beans first since they take slightly longer to soften. Simmer for about 3–4 minutes.
Add cherry tomatoes and snap peas last, cooking just until tender but still vibrant.
The vegetables should remain slightly crisp to contrast the tender fish.
Step 5: Poach the Fish
Reduce the heat to low. Carefully nestle the seasoned fish fillets into the simmering coconut broth. Spoon a little broth over each fillet.
Cover the pot and let the fish gently poach for about 6–8 minutes, depending on thickness.
The fish is done when it turns opaque and flakes easily with a fork. Avoid overcooking—fish continues to cook slightly even after removing from heat.
The gentle poaching method ensures the fish stays moist and delicate.
Step 6: Final Flavor Boost
Turn off the heat and stir in fresh lime juice. Taste and adjust seasoning—more lime for brightness, fish sauce for saltiness, or a pinch of sugar for balance.
Sprinkle freshly chopped cilantro, basil, and scallions over the top.
The herbs add freshness and lift the creamy richness of the coconut milk beautifully.
How to Serve
Spoon jasmine rice into bowls. Gently place a fillet of fish on top. Ladle the coconut broth and vegetables generously over everything.
Garnish with extra herbs and chili slices if desired.
Serve immediately while warm and fragrant.
Chef’s Tips for Perfect Coconut Poached Fish
- Keep the heat gentle – Never boil the coconut milk aggressively.
- Use full-fat coconut milk – It creates the richest, creamiest broth.
- Add lime at the end – This preserves its bright, fresh flavor.
- Do not overcrowd the pot – Fish should sit comfortably in the broth.
- Taste and adjust – The magic lies in balancing sweet, salty, sour, and spicy.
Flavor Variations
1. Lemongrass Infusion
Add 1–2 smashed lemongrass stalks to the broth while simmering for extra fragrance.
2. Spinach & Mushrooms
Add baby spinach and sliced mushrooms in the final minutes of cooking for an earthy twist.
3. Turmeric Coconut Fish
Add ½ teaspoon turmeric for a golden broth with subtle warmth.
4. Spicy Version
Increase red curry paste or add a spoonful of chili oil for deeper heat.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 2 days.
To reheat, warm gently over low heat. Avoid boiling, as this can overcook the fish and cause the coconut milk to split.
This dish does not freeze well due to the coconut milk and delicate texture of the fish.
Why This Recipe Works
Poaching fish in coconut milk protects it from drying out. The fat in the coconut milk creates a gentle cooking environment that keeps the fish tender.
The curry paste provides depth, while lime juice and fresh herbs add brightness. The balance of salty fish sauce, sweet sugar, spicy chili, and tangy lime mirrors classic Southeast Asian flavor profiles.
Because everything cooks in one pot, the flavors intensify and blend beautifully.
