Kirkland Signature Wild Chilean Sea Bass is a premium wild-caught seafood offering sourced from the cold waters of the Southern Ocean. Also known as Patagonian Toothfish, Chilean Sea Bass is celebrated for its firm, white flesh, buttery melt-in-the-mouth consistency, and delicate flavor profile often compared to black cod or scallops. The fish is hand-trimmed into boneless, skinless fillets and is MSC Certified for sustainable, responsibly sourced seafood.
Sold previously frozen and priced per pound, this fish is best thawed slowly in the refrigerator overnight, kept covered to retain moisture. Once thawed, it can be pan-fried to develop a golden crust, poached for an extra-tender result, or grilled with garlic butter. Do not refreeze once thawed, and use within a couple of days of defrosting.
