Fresh wild-caught ahi tuna (yellowfin tuna) sold by the pound from Costco's seafood department. This sushi-grade tuna features a deep red color and firm texture, ideal for searing, grilling, or serving raw as sashimi or poke bowls. The fish is wild-caught and sold as fresh steaks, typically in packages weighing around 1.5 to 2 pounds.

Ahi tuna is a lean, high-protein fish rich in omega-3 fatty acids, selenium, and B vitamins. It is naturally low in saturated fat and provides a clean, mild flavor that pairs well with soy-based marinades, sesame, ginger, and wasabi. For best results, sear briefly on high heat to achieve a crispy exterior while keeping the center rare to medium-rare.
