Oh, Costco. It’s as if entering a treasure trove chock full of bulk purchases, from where you can pick up from a humongous jar of pickles to. a flat-screen television in one location. For all of us who enjoy to indulge in a bargain, Costco’s broad aisles are literally a play area, with unbeatable value for household essentials, party fare, and even nice surprises like kayaks or designer eyeglasses. As one who enjoys a little rush of getting a bargain, I ought to be astounded at Costco’s ability of delivering decadent amounts without it costing an arm and a leg.
But then again while Costco is a saint for buying pantry items or kid-friendly frozen meals in bulk, not all that one can locate in those ginormous warehouses can be a feast fit for the gods. When it comes to seafood, especially delicate proteins like salmon or shrimp, the bulk-buy model doesn’t always guarantee top-notch quality. As a home cook who’s passionate about creating memorable meals, I’ve learned that a discerning eye is key to navigating Costco’s seafood section. It’s not about dismissing the store entirely it’s about knowing what to pick and what to skip to ensure your dishes shine.
That’s where culinary wisdom comes in, and I’m excited to share insights inspired by experts like Chef Lizzy Briskin, who’s dished out some eye-opening advice about Costco’s seafood offerings. Whether you’re planning a fancy dinner party or just want a weeknight meal that feels special, understanding the nuances of Costco’s seafood can make all the difference. Let’s take a closer look at bulk seafood, determine why certain products fall short, and learn how to make smarter decisions that bring your cooking to the next level.
Why This Matters to Home Cooks
- Save time and money: Avoiding disappointing buys saves you both.
- Make meals pop: Making better selections makes food look and taste as pretty as possible.
- Shop with confidence: With a knowledge of what to hunt for in the wilds of Costco, you’ll feel confident in shopping like a pro.

The Deceptions of Frozen and Pre-Seasoned Salmon
And then salmon one of the sea’s crown jewels. Something alchemy-like happens when a perfectly cooked fillet of salmon is served, its buttery taste and flaky, tender texture. But not all salmon is created equal, particularly at Costco. Executive chef Lizzy Briskin, in a tell-all interview to Insider, spilled the beans: she avoids Costco’s pre-seasoned, frozen salmon. Having spent years of my life making seafood recipes from scratch myself, I wondered why she does that and how it would affect me and everybody else who’s a fish cooking fanatic,
The problem with pre-seasoned and frozen salmon is texture and taste. Frozen too hard, salmon develops ice crystals in tender muscle tissue. Thawed, the crystals lead to crystallization of the juices, collapsing cell walls and leaving fish mushy and waterlogged. Mix with pre-applied marinades particularly acidic marinades such as lemon or vinegar-based marinades and the issue is exacerbated. These marinades, meant to add flavor, can over-tenderize the fish if left for too long, dismantling its proteins and turning a once-colorful fillet into a soggy letdown. I’ve been there, expecting a restaurant-quality dish only to end up with something that feels like a culinary letdown.
Instead of settling for convenience, Briskin suggests heading straight to Costco’s fresh seafood counter. Yes, fresh salmon will set you back a few more dollars, but as she says, “you’re paying for quality.” And let me tell you, that quality is worth it when you’re setting your sights on a dish that impresses. Fresh salmon stays fresh and keeps its authentic flavor, so you season it as you like either a dash of salt and pepper or the pungent ginger-soy sauce that is great with rice or a green salad. It’s having some control over what is in my meal, rather than relying on a pre-prepared marinade.
Tips for Selecting Fresh Salmon
- Check the color: It should have bright, pink-orange color to test freshness.
- Check the texture: Fresh salmon should be firm, not slimy or mushy.
- Ask about origin: Costco personnel are normally more than willing to tell you where the fish was caught, and thereby allow you to make informed decisions.

The Hidden Downsides to Processed Seafood
The aisles of Costco freezers are a convenience heaven filled with giant bags of breaded fish and shrimp and sticks that promise to provide speedy, kid-friendly meals. Consider Trident Seafoods’ “The Ultimate Fish Stick.” The package promises top-quality Alaskan pollock smothered in light, crunchy Panko breadcrumbs, but what does it actually contain? All breading and very little fish. As a mom who’s attempted to sneak in some of the nutritious seafood to weeknight meals, I’ve discovered that these ultra-processed foods cut corners on quality to save you pennies and ultimately end up forming a starchy, disappointment bite.
The arithmetic is revealing: fish costs more than breading does, so that these fish sticks cut corners on the best. One third breading, covering the fragile pollock in a thick, sticky layer. And then there are additives sodium and maltodextrin, to name only two. Three fish sticks contain 14% of your daily sodium, and processed carb maltodextrin will raise blood sugar levels and kill off your gut. As someone who attempts to make dinner healthy, I catch myself wondering if the convenience is worth it.
This is more than just about fish sticks. Costco’s Kirkland Signature Tempura Shrimp, for example, is a pricey shortcut to restaurant-quality appetizers in the home. Restaurant customers complain, however, that the heavy batter overwhelms the shrimp, with little room for its natural flavor. I’ve had similar experiences with processed seafood expecting a crispy, succulent bite only to get a mouthful of coating. It’s a reminder that when it comes to seafood, less processing often means more flavor. Next time you’re tempted by a giant box of frozen shrimp or fish sticks, consider whether a fresh alternative might better suit your taste buds.
Red Flags in Processed Seafood
- High breading ratio: Look for products where seafood is the main attraction, not the batter.
- Additive overload: Be wary of sodium, maltodextrin, or artificial flavors listed on the label.
- Texture test: If it’s too heavy or oily to the touch, it’s likely more batter than seafood.

The Challenges of Farmed and Imported Seafood
Sourcing matters, especially when shopping at a global giant such as Costco. Their seafood selection is plentiful steaks of tuna, shrimp, lots of tilapia but all of it doesn’t live up to the hype. Take tilapia, for example. Once the fish version of the underdog, it’s now ubiquitous because it’s bland and inexpensive. But Costco’s Aqua Star Farmed Tilapia Fillets are grown on factory farms that feed fish unnatural diets, and less-tasty fish is the result. As a frugal radical, I’ve been lured by that $60 10-pound deal, only to discover later that you can get the same tilapia at Walmart for $4.25 per pound. The “bargain” doesn’t look so clever anymore.
Foreign shrimp is another category where caution must be exercised. Costco sources most of its shrimp from overseas companies such as Kader Exports, which may have inconsistent levels of sustainability and safety measures. Costco shrimp has been tagged a concern for the FDA, with a 2020 salmonella recall and a 2024 import prohibition on antibiotic and waste contamination issues. Being a health- and earth-mindful individual, all these warning signs make me want to avoid grabbing that large bag of frozen shrimp. It’s not just about taste it’s believing what is in front of you.
The good news? Costco is starting to improve its shrimp supply chain, though gradually, according to analysts like Environmental Defense Fund’s Tim Fitzgerald. Meanwhile, I use shrimp that boast open sustainable credentials, ideally domestic origin. It’s a tiny extra step which ensures that I am encouraging good practice and protecting my family. As you shop the seafood stand at Costco, notice country of origin it’s an easy way to make a smarter choice.
How to Shop Smarter for Shrimp
- Bring in U.S.-sourced shrimp: National regulations will be more powerful for safety and sustainability.
- Check for certifications: MSC (Marine Stewardship Council) labels mean responsible harvests.
- Costco employees will tell you freshness and where it came from.

When Premium Promises Fall Flat
Costco likes to boast about its seafood as premium, and then some of it doesn’t quite live up to the promise. Try using the Aysen Coho Salmon Fillets, which are promoted as being “sashimi quality.” Like with any one imagining cutting slinky raw salmon into pieces for making sushi at home, I was enthralled until I discovered these fillets have been frozen. Freezing is a nightmare for finicky fish, shattering it into unpleasant pieces upon thawing. And real sashimi-grade salmon requires indulgent fat marbling and skin-off fillets, which Ryan and other consumers complained were lacking. It’s a good old-fashioned case of hype overcoming reality, and it’s left me skeptical about believing labels that sound like breathlessly gushing pamphlets.
And finally is the Orca Bay Keta Salmon, also commonly referred to as “chum” or “dog salmon” because of its role in pet food. It’s inexpensive and abundant, but oily and thus not ideal for fresh preparation. Customers find it dry, fishy, and too soft not exactly the centerpiece of a gourmet dish. I’ve made the mistake of buying budget-friendly fish only to regret it when the flavor falls flat. It’s a reminder that abundance doesn’t always mean quality, especially for seafood meant to shine on your plate.
Even luxury items like Rastelli’s Filet Mignon & Maine Lobster Tails combo can disappoint. Priced at a premium, these boxes promise top-tier seafood, but reviews tell a different story. Customers report mushy lobster tails and fishy, breading-heavy crab cakes that feel more like filler than gourmet fare. As someone who loves splurging on special ingredients for date nights, I’ve learned that a high price tag doesn’t guarantee a five-star experience. For true quality, I’d rather seek out fresh lobster or crab from a trusted fishmonger.
Avoiding Misleading Premium Products
- Read reviews: Browse customer reviews on Costco’s website or websites such as Reddit.
- Check packaging: Observe transparent information regarding sourcing and processing.
- Purchase first for fresh: Frozen “premium” seafood will spoil in stock.

Smart Seafood Shopping at Costco
Costco’s seafood department is a grab bag to a certain extent, but with a little insider information, you can find gems that make your meals memorable. The trick is to seek out freshness and simplicity. Fresh fish off the fish counter, say, allows you to season and cook as you wish, a dish all your own. I adore trying out flavors such as garlic-herb butter or a zesty citrus glaze brushing over a tabula rasa. Fresh fish also remains firm and flavorful, so every mouthful is paradise.
For shrimp, tuna, or any seafood, ensure you check the source. Wild-caught, such as Safe Catch’s Wild Ahi Yellowfin Tuna, tend to have more taste and nutrition, with greater omega-3s and less mercury. When purchasing frozen, ensure minimal additives and transparent sourcing information. I’ve found that products with certifications from groups like the Marine Stewardship Council are more likely to align with my values as a conscious consumer. It’s about balancing convenience with quality to create meals you’re proud to serve.
Lastly, buying seafood at Costco is merely a game of being a smart home cook. If you steer clear of all those overly processed, pre-seasoned, or fishy-named foods, you can guarantee your food is as tasty as it is healthy. So the next time you’re wheeling that behemoth of a cart down Costco’s aisles, take a minute to make smart choices. Your taste buds and your dinner party guest list will appreciate it.
Your Seafood Shopping Checklist
- Go fresh whenever possible: Use the seafood counter rather than frozen for improved texture and taste.
- Read labels attentively: Steer clear of products with too much sodium, additives, or vague origins.
- Try it at home: Purchase fresh and make your own marinades for a personal touch.
