There’s something calming about simmering a pot of coconut milk infused with lemongrass on a quiet evening. The aroma fills my little Chicago kitchen, wrapping me in the warmth of memory. It’s the kind of scent that makes you pause citrusy, creamy, slightly floral like a gentle whisper from the coast of Thailand.
When I was growing up, my grandmother would simmer herbs and spices without ever measuring a thing. She said, “You’ll know when it’s right by the smell.” This Lemongrass Poached Halibut carries that same intuitive spirit. It’s light but layered with flavor the creamy coconut broth cradles tender halibut, the lime zest adds brightness, and the lemongrass brings that perfect hint of tropical calm.
If you’ve ever wanted to feel like you’re dining beachside, with the sea breeze kissing your face, this dish might just take you there. And the best part? It takes less than 30 minutes to make.

How to Make Lemongrass Poached Halibut
1. Prepare the Broth
In a medium saucepan, combine coconut milk, broth, lemongrass, lime leaves, ginger, garlic, shallot, salt, sugar, and fish sauce. Bring to a gentle simmer over medium heat. Let it bubble softly for about 10 minutes, just until the flavors blend into a fragrant base.
2. Season the Halibut
While the broth simmers, pat the halibut dry. Brush each fillet lightly with olive oil and sprinkle with salt and black pepper. The mild flavor of halibut makes it a perfect canvas for this aromatic broth.
3. Poach Gently
Lower the heat so the liquid barely trembles. Slide the halibut fillets into the broth, ensuring they’re just submerged. Cover with a lid and poach for 7–9 minutes until the flesh flakes easily but remains moist.
4. Remove and Rest
Using a slotted spatula, carefully lift each fillet out and place on a warm plate. Tent with foil while you finish the broth.
5. Finish the Broth
Strain the liquid through a fine sieve for a smooth finish (optional). Add lime juice and zest. Taste and adjust with a little fish sauce or more lime juice for balance.
6. Serve Beautifully
Ladle the fragrant broth into shallow bowls. Gently nestle a fillet of Lemongrass Poached Halibut in the center. Garnish with chopped cilantro, Thai basil, and red chili slices.
The result? A dish that’s elegant enough for guests yet simple enough for any Tuesday night.
What to Serve With It
Steamed jasmine rice – It soaks up every drop of the coconut-lime broth.
Light cucumber salad – Add a crisp contrast (try my Cucumber Salad Mediterranean).
Garlic sautéed greens – Baby bok choy or spinach balances the creaminess perfectly.
You can also pair it with a chilled Sauvignon Blanc or sparkling lime water for a refreshing finish.
Tips for Perfect Results
Gentle heat is key.
Keep the broth just below a simmer to ensure the fish stays tender and silky.
Use fresh lemongrass.
Dried lemongrass doesn’t compare. Look for firm stalks with a bright, lemony scent.
Taste before serving.
Balance the coconut milk’s richness with just enough lime juice to lift the flavor.
Don’t rush it.
The broth gains its depth from a slow 10-minute simmer give it time to bloom.
Storage Instructions
Fridge: Store halibut and broth separately in airtight containers for up to 2 days.
Reheat: Warm the broth gently, then slide in the fish just until heated through.
Freeze: Not recommended the texture of poached fish becomes grainy once thawed.
