Wild Chilean Sea Bass, also known as Patagonian Toothfish, is a premium wild-caught fish prized for its exceptionally rich, buttery flavor and moist, flaky texture. Costco's offering is sourced from Australia, previously frozen, and thawed for fresh sale in the seafood section. It carries MSC (Marine Stewardship Council) Certification, confirming it is sustainably sourced wild seafood. This item is sold by weight at the meat and seafood counter, so the final price depends on the package weight selected.

The fish is hand-trimmed and typically boneless, making it straightforward to prepare at home. Chilean Sea Bass is one of the most sought-after and premium fish varieties available, distinguished by its high fat content that produces a luxurious, melt-in-your-mouth quality. It pairs beautifully with light butter sauces, fresh herbs, and citrus.

To cook, pan-sear over medium heat with butter and herbs for 10 to 15 minutes until the flesh is flaky and opaque, then finish with a squeeze of fresh lemon juice. Avoid overcooking, as the fish transitions quickly from perfectly flaky to dry.
