10 Best Costco Seafood Items Shoppers Adore 

Good-quality fish is not only delicious but also loaded with health benefits. However, it can be quite expensive. That's one reason so many shoppers choose to get their seafood from a value-driven retailer like Costco.

America's preeminent warehouse club offers a variety of both fresh and frozen seafood. Some options are ready to heat and serve as-is, while others require additional prep work and knowledge of cooking seafood before serving. As seafood aficionados attest, the offerings at Costco rival many other grocery options, even the local fish market. However, not all of Costco's seafood products are runaway hits, so it's best to turn to the experts—Costco's frequent shoppers—to determine which ones are worth buying on your next grocery run.

Several seafood items at Costco are only available when the fish is in season. However, you can find some year-round options, especially in the frozen foods section of the warehouse. Costco members largely endorse the following seafood items, which should find their way to your shopping list the next time fish is on the menu at home.

Kirkland Signature Tempura Shrimp

Among the frozen appetizers at Costco, few are as popular as the Kirkland Signature Tempura Shrimp. Cocktail hour can be ready in a matter of minutes with this 30-count package of shrimp, which also includes soy sauce. The shrimp is an instant hit with guests, as one Costco shopper shared on Reddit: "We have served these at a few parties, can highly recommend!"

The shrimp work perfectly as-is, or they can transform into a more elaborate meal. One Costco member shares their favorite way to prepare them, saying that the shrimp "with the udon noodles are KILLER, or making homemade sushi rolls using the farm salmon from Costco. Chef kiss." Another Redditor suggested, "They make wonderful bang-bang shrimp tacos. Low risk, high reward meal."
