Costco members have access to a slew of perks. There are the free samples, of course, discounts on electronics and appliances, lower fuel costs, and affordable groceries. Bulk buying allows shoppers to get more while spending less, and the chain's Kirkland Signature products are famous for their quality and value. In our ranking of the best new Costco items in 2026, a certain store-brand freezer find really caught shoppers' attention. The Kirkland Signature Atlantic blackened salmon comes with six seasoned fillets and retails for $25.69 per pack. Customers have publicly declared their affinity for the frozen fish.

According to online buzz, the blackened salmon is gearing up to be a Costco all-timer. "This is going to be a regular staple in my pantry," said one customer in a website review. On Reddit, a shopper declared, "Kirkland Blackened Atlantic Salmon is amazing!" A commenter on the thread agreed, stating, "Tons of flavor and lots of juice. Prepared rice with it for a full meal. Would definitely buy again." 

According to the package instructions, the Kirkland Signature Atlantic blackened salmon comes out best when baked in a conventional oven. The instructions also recommend letting the fillets thaw in the fridge for at least 12 hours (though you can bake them right out of the freezer as well). To make sure your baked salmon is perfectly moist every time, remove it from the oven a bit before it reaches the safe internal temperature of 145 degrees Fahrenheit. The fish continues cooking out of the oven, so pulling it from the heat a little early lessens the chances of dry salmon disrupting your dinner. Use a food thermometer to determine when the salmon is ready to eat, then dig in.

If you're thinking about pairings, shoot for uncomplicated side dishes that allow the fish's blackened seasoning to shine. A simple roasted asparagus recipe works beautifully here, and lemon rice (white rice infused with lemon juice and zest) will lend some acidity to the meal. You could also serve the fillets on top of a quick, wholesome salad with lettuce, avocado, red onions, feta cheese, and a zesty citrus dressing.
