Making this easy barramundi recipe
These barramundi fillets are simple to prepare. With just a few minutes of pan-frying on each side of the fish and a few more minutes to make the sauce, it’s ready to be served.
You’ll need these ingredients to make the recipe:
- 3 barramundi fillets, about 4 ounces each
- Sea salt and cracked black pepper to taste
- 2 teaspoons of canola oil
- 2 tablespoons of unsalted butter
- 1- 2 cloves of garlic, minced
- 3 tablespoons of fresh lemon juice
- Small bunch of fresh basil

How to cook barramundi fish
Barramundi is a very delicate fish that needs minimal cooking time. The best way to cook barramundi is to sear the fillets lightly for 4-5 minutes on each side in a non-stick skillet.
Since the flavor is so delicate, it pairs well with a bright sauce like the lemon and butter sauce in this recipe.
Rub some of the canola oil on the barramundi fillets. Add the rest of the canola oil to the pan and pan-sear the fillets over medium-high heat for about 4-5 minutes on each side.
To test the barramundi for doneness, use a fork to pierce the fillets on an angle at the thickest point and twist gently. If it is done, the fish will flake easily and lose its translucent appearance.

Making the sauce for barramundi
Since barramundi fillets have a buttery flavor, the lemon butter sauce complements them beautifully. The sauce is easily made from butter, garlic, basil, and lemon juice.
Move the barramundi fillets to a serving plate and keep them warm while you prepare the sauce.
Scrape up any bits left in the pan, reduce the heat to medium, and add the butter. Stir in the minced garlic and gently cook for about 2 minutes.
Add the lemon juice with the fresh basil and cook until the sauce is fragrant, approximately 1 minute. That’s all there is to making this easy barramundi sauce!

Drizzle the lemon butter sauce over the barramundi fillets and garnish them with fresh basil. The recipe takes about 12 minutes to prepare, but who would believe that when you look at this beautiful dish?
Serve this barramundi fillet recipe with a side salad or some tasty oven-roasted root vegetables.

This sounds really delicious, but I am not a fan of basil. Can you suggest some other flavor full herb that I might use?

Hi Nancy, A favorite herb of mine with any type of fish is tarragon. It has a mild licorice taste that would do well. You could also try dill, fennel or marjoram. None of these are very strong and suit fish well.

It was very good. One small mistake I made: I put the butter, garlic and basil into the pan pretty much immediately after removing the fish and the pan was still super hot. So the butter / garlic cooked a bit too fast and burned slightly. So I put the sauce in a separate small container (instead of pouring over the fish) when I served so we could dip into it in small doses. Still, quite tasty.
