Chilean Sea Bass, also known as Patagonian Toothfish, is one of the most prized seafood options available, recognized for its rich, buttery flavor, moist flesh, and large, delicate flakes. This wild-caught fish is sourced from the pristine waters off the coast of Chile and carries MSC (Marine Stewardship Council) Certification, confirming it comes from a well-managed, sustainable fishery.

Sold per pound from the Costco seafood counter, this fish is previously frozen and arrives hand-trimmed, boneless, and skinless — ready to cook with no additional prep required. Individual vacuum-packing preserves freshness and makes portioning straightforward for home cooking or meal planning. Keep frozen until ready to prepare.

Chilean Sea Bass is highly versatile in the kitchen. Its elevated fat content keeps the flesh tender and moist through a variety of cooking methods, including pan-searing, oven-baking, grilling, and broiling. A simple preparation with butter, herbs, and citrus is all that is needed to highlight its natural flavor.
