What’s your favorite fish? Mine is sea bass, without question. If you’ve never had it, I’m here to tell you, you’re missing out. Any time sea bass is on a menu at a restaurant, I have to order it. Full transparency: every time I make it at home, I can never get it to taste as good as it does in restaurants. And then I discovered The Better Fish.
So… you want to make some of the most delicious fish you will probably ever make in your own kitchen?! Keep reading.
The first thing you’ll need is this Kirkland Signature Ocean-Farmed Barramundi by The Better Fish exclusively for Costco. Barramundi, a type of sea bass, is a premium white fish that is succulent, mild, and buttery. It eats similar to mahi and grouper- a good amount of oil, but not super fishy, which is a plus for me. I first tried The Better Fish almost a year ago, and literally have been hooked ever since. Once I saw that they had the skin on fillets at select Costco’s , I was at my location soon as they opened!
I decided to grill the fish with just salt, pepper, EVOO, and butter. Then, I made my rendition of a delicious and creamy lemon beurre blanc. Two words: GAME CHANGER! I gave a sneak peak here on my Instagram, but I’m giving away all the yummy details here on the blog, so you’re in the right place. Listen to me and listen to me good: GO GET THIS FISH! You can find it at select Costco’s in the Northeast, Southeast, California, Texas, and Pacific Northwest. Find a location that carries it near you by clicking here.

- In a saucepan over medium heat, bring lemon juice, wine and shallots to a boil. Cook until shallots become translucent and slightly pink in color. Sauce should thicken and reduce.
- Add heavy cream and sour cream to the pan, and stir. Boil for another 2-3 minutes then turn heat to low.
- Once heat is on low, add in butter, 1-2 tbsp at a time, and stir. Make sure all butter is dissolved before you add more.
- Once all butter is melted in, remove from heat, add dried parsley, salt, and pepper. Stir and make sure all is well incorporated.
- Pour as much, or as little sauce over your fish and enjoy.
