Fresh wild-caught mahi mahi fillet, sold by the pound at the Costco seafood counter. Mahi mahi is a tropical ocean fish prized for its mild, slightly sweet flavor and firm, meaty texture. Unlike fattier fish such as salmon, mahi mahi has a dense, satisfying flesh that holds together well during cooking, making it ideal for a wide variety of preparations.

This fresh fillet is versatile and easy to cook. It can be grilled over medium-high heat in about 7 minutes per side, baked at 400°F for 10–12 minutes, pan-seared, poached, or prepared in an air fryer. Cook to an internal temperature of 140°F for best results. The mild flavor pairs well with a wide range of seasonings, from simple salt and pepper to bold blackening spice, citrus marinades, or tropical fruit salsas. Mahi mahi is especially popular in fish tacos, grilled fish sandwiches, and rice or cauliflower rice bowls.
