Fresh wild-caught Opah fillet sold by the pound, available at select Costco warehouse locations. Opah, also known as moonfish, is a large, deep-water oceanic species prized for its rich, firm flesh and distinctive flavor profile that sits between swordfish and tuna. The meat features multiple distinct color zones ranging from bright pink to deep red and white, each with slightly different taste and texture characteristics.

Opah is highly versatile in the kitchen and works well grilled, pan-seared, baked, or broiled. Its high fat content keeps it moist during cooking and lends a buttery, mildly sweet flavor. It pairs well with citrus, herbs, and light sauces. As a wild-caught species typically harvested in the Pacific Ocean, opah offers a good source of lean protein and omega-3 fatty acids.
