How Long to Cook Barramundi
Barramundi — known as Asian sea bass or giant perch — is one of the world’s finest white-fleshed fish. Native to the Indo-Pacific region and now widely farmed across Australia, Southeast Asia, and the Middle East, it produces thick, milky fillets with a sweet, buttery flavor and firm, moist texture that holds together beautifully during poaching. Its mild flavor takes aromatics readily.

Barramundi Cooking Time Calculator
Select the form and cooking method for an estimated cooking time.
Cooking temperature: liquid at 82 to 90°C / 180 to 194°F. Start timing once the water reaches a gentle simmer.
These estimates assume fillets of 1.5 to 2 cm thickness. Always test at the thickest point — the flesh should be opaque and flake easily.
Preparation
How to Prepare Barramundi Before Cooking
Scale from tail to head using the back of a knife or a fish scaler. Gut by making a belly incision from vent to gills. Remove gills if cooking whole. Rinse the cavity under cold running water until clear.
For fillets: cut along the backbone close to the spine. Remove pin bones with tweezers. Pat dry. For steaks: slice across the body into 3 to 4 cm thick pieces through the backbone with a sharp heavy knife.
Method
How to Cook Barramundi Step by Step
- Scale, gut, and rinse the fish thoroughly.
- Cut to your chosen form: fillets, steaks, or leave whole.
- Place in a pot and cover with cold water.
- Bring slowly to a gentle simmer over medium heat.
- Skim foam that rises in the first 3 minutes.
- Add onion, carrot, bay leaf, lemon slice, peppercorns, dill, and parsley stalks.
- Reduce heat to maintain a gentle simmer — surface should barely tremble.
- Cook: fillets 12 to 15 min, steaks 15 to 20 min, whole fish 20 to 30 min.
- Test at the thickest point — flesh must be opaque and flake easily with a fork.
- Remove carefully with a slotted spoon, salt after plating, and rest 2 minutes.

Doneness
How to Know When Barramundi Is Done
The flesh turns uniformly opaque white and flakes easily at the thickest point with gentle fork pressure. There should be no translucent or gelatinous patches remaining. The internal temperature should reach 63°C / 145°F.
Safety note: ensure the flesh is fully opaque throughout with no translucent sections before serving. The internal temperature must reach 63°C / 145°F at the thickest point.
Seasoning
Best Seasonings for Barramundi
Barramundi suits mild, aromatic poaching liquids. Court-bouillon with white wine, lemon, fennel fronds, and dill is classic. Asian preparations use ginger, soy, sesame oil, and scallion in the steaming water. Avoid very acidic or strong-flavored liquids that overpower the delicate flesh.
Avoid this
Common Mistakes
- Boiling too hard — breaks up the delicate flesh into pieces.
- Salting during cooking — draws out moisture and toughens the flesh.
- Overcooking — barramundi turns dry and woolly quickly past done.
- Not removing gills from whole fish — makes the broth bitter.
- Skipping rinsing the cavity — can cause off-flavors in the finished dish.
Serving
What to Serve With Cooked Barramundi
Excellent with beurre blanc, hollandaise, or a light lemon-butter sauce. Pair with steamed jasmine rice, new potatoes, or braised fennel. The poaching broth is ideal for making a light fish velouté. Barramundi works cold as well as hot — excellent in salads and sandwiches.
