Costco's Service Deli seared ahi tuna with yuzu sauce is a fresh, prepared seafood item sold by the pound at the deli counter. The ahi tuna (yellowfin tuna) is seared on the outside with a lightly cooked crust while remaining tender and rare inside, delivering a restaurant-quality texture and flavor profile.

The dish is finished with a yuzu sauce, a bright and citrusy Japanese condiment made from yuzu fruit that adds a tangy, aromatic complement to the rich tuna. It can be served chilled or at room temperature as a protein-forward main, sliced over salads, or paired with rice for a sushi-inspired meal.

As a fresh deli item, availability varies by location and date. This product is a newer addition to Costco's prepared deli offerings, noted for its clean ingredients and elevated flavor combination suitable for sushi-grade eating occasions.
