What Makes This Recipe So Good

  • Barramundi is an absolutely delicious fish! Flaky, mild, delicate, you might have heard it referred to as the Asian seabass. It’s meaty, with a its own buttery flavor. It doesn’t have a strong fishy taste at all, so this is one fish dish the whole family will enjoy!
  • Not only is it delicious, barramundi is also a sustainable option that’s super nutritious. Naturally low in calories and high in lean protein, it’s packed with important nutrients like heart-healthy omega-3 fatty acids.
  • This recipe is SO quick and easy! I’m talking restaurant-quality in less than 15 minutes. Since it’s so quick, you’ll want to prep all your sides first. The fish needs to be the last thing you cook so you can serve it immediately.

Chef’s Tips

  • Because barramundi is very delicate, you’ll want to use a non-stick pan. I also recommend using a fish spatula if you’ve got one – it’ll help you flip the fillets without tearing them. If you’re on the fence about getting one, don’t let the name sway you. It’s super versatile and you can use it any time you’d use a traditional spatula.
  • Pat down the fish with a paper towel before adding it to the pan so you get a perfect sear. It’s a simple step that only takes a few seconds but really makes a difference in the end!
  • Barramundi is often found frozen, packaged in individually-wrapped pieces, and you’ll want to defrost it before cooking. The easiest way is to just put it in the fridge the night before. You should wake up to perfectly tender barramundi fillets. If you forget, you can also submerge the wrapped fillets in cold water for 30 minutes or so. If the fish isn’t already packaged in plastic, place it in a ziploc bag or any sealable bag before you put it in the water.
