Fresh Wild Mahi Mahi (also known as dorado or dolphinfish) is a prized wild-caught ocean fish celebrated for its firm, meaty texture and mild, slightly sweet flavor that appeals even to those who are not typically fond of seafood. Costco sources fresh wild mahi mahi fillets and sells them by the pound, giving members access to premium-quality fresh fish straight from the seafood counter.

Mahi mahi is exceptionally versatile in the kitchen. Its dense, moderately flaky flesh holds up beautifully to high-heat cooking methods such as grilling and pan-searing, and it also bakes well at 400°F for 10–12 minutes or until the internal temperature reaches 158°F. It is a natural choice for fish tacos, served alongside fresh mango salsa or citrus-based slaws. Because the fillets arrive unseasoned, home cooks have full control over flavor — from simple salt and pepper to bold blackening spices or herb marinades.

Mahi mahi is one of the most nutritious seafood options available. It is an excellent source of lean, high-quality protein and omega-3 fatty acids, which support heart and brain health. The fish is naturally low in saturated fat and calories, making it a smart addition to a balanced diet.
