It’s a blank canvas for your culinary creativity, perfect for a pan-seared lemon caper mahi mahi dish. Each 3-pound bag packs 21 grams of protein per serving, making it a solid choice, though its dense texture placed it at the bottom of our rankings.

With a whopping 37 grams of protein per serving, it’s a powerhouse in the nutrition department. The 2-pound bag is one of the pricier options, but for those who prefer a less dense texture than mahi mahi, it’s a worthy investment.


5. Farm Raised Tilapia​


The Kirkland Farm Raised Tilapia is a budget-friendly option that doesn’t skimp on flavor. Despite being farm-raised, this tilapia is free from antibiotics and offers a flaky texture with a mild fishiness that can be easily enhanced with your favorite seasonings.

Each 3-pound bag contains 23 grams of protein per serving, and its affordability makes it a great value for families. It’s a bit delicate, but with a little care, it can be a star on your plate.


4. Kirkland Wild Caught Alaska Sockeye Salmon​


The vibrant pink of the Kirkland Wild Caught Alaska Sockeye Salmon is a feast for the eyes and the palate. This fish boasts a classic umami, buttery taste and the highest protein content on our list at 38 grams per serving.

The skin, which is left on, can be easily removed after cooking, but we recommend savoring it for an added flavor boost. The 3-pound bag is priced on the higher end, but for a frozen high-protein option, it’s a catch worth considering.


3. Kirkland Wild Alaskan Pacific Cod​


Our bronze medal goes to the Kirkland Wild Alaskan Pacific Cod. This mild white fish has a buttery texture that’s flaky and soft, making it our favorite fish from the haul. It’s not too dense and has a slight wateriness that doesn’t detract from its taste.

2. Kirkland Wild Argentine Red Shrimp​


Swimming into second place are the Kirkland Wild Argentine Red Shrimp. These peeled and deveined beauties are easy to cook and boast a fantastic delicate consistency.

With 18 grams of protein per serving, they may have the lowest protein content on our list, but their texture and mild taste more than make up for it. Whether you’re whipping up a garlic butter shrimp dish or something more exotic, these shrimp are sure to impress.


1. East Coast Seafood Japanese Hokkaido Scallops​

And now, the moment you’ve been waiting for – the crowning jewel of Costco’s frozen seafood section: East Coast Seafood Japanese Hokkaido Scallops. These scallops are tender, buttery, and simply melt in your mouth.
