    Costco Scallops Decoded: A Flavorful Journey from Package to Plate

    Costco has long been known for its quality seafood, from shrimp to salmon; fans rave about its offerings. But one type often swims under the radar: Costco Scallops.

    Available year-round in the frozen section, these bivalves make it easy to create a fancy dinner your guests will love with little effort. But are Kirkland Signature Frozen Scallops any good? Read on as we give an honest review and delve into how to cook them. 

    Let’s get to it!

    Does Costco Have Good Scallops? An Honest Costco Scallops Review

    When choosing scallops, you want to look for ones under 10 per pound, which smell like saltwater and are firm and dry. Costco Scallops checks almost all of those boxes. 

    Upon opening the bag, you get a strong whiff of seawater. There is no fishy smell.

    They are sold frozen, so you can’t tell their texture right away, but after defrosting, you’ll notice their firmness with a quick touch. If you wonder if fresh is better, the answer is not always. Frozen can be a great option since they are immediately flash-frozen after being caught, and many people don’t have access to freshly caught scallops.

    Kirkland Signature Frozen Scallops are dry, which means they are free of preservatives that increase moisture and weight. This results in less water held by the scallop and allows for a better crust on the outside.

    The one downside to Costco Scallops is their size. While some suggest that the larger scallops are better, these are smaller, with 15-20 in a pound. We liked the smaller size because we were satisfied after eating three. 

    Now that we know what to look for let’s see if Costco Scallops are any good. 

    Spoiler Alert: Costco scallops are good!

    They have a mild flavor and are easy to prepare. They didn’t contain excess moisture, which allowed them to get a good crust, which is crucial as the texture of bivalves can be a little blah without a good sear. We’ve had fresh scallops from the local fishmonger several times and can’t taste the difference between the two.

    As for preparation, it was pretty straightforward. We placed the scallops in a covered container in the fridge in the morning to defrost. It took a little longer than the eight hours suggested by the package, so we set them in a freezer bag under running water for 7 minutes to finish defrosting. From there, we put them on a paper towel and then topped with another layer in the fridge while we prepped our sauce and got the pan screaming hot.

    Cooking was a breeze once we got the pan hot enough. While the package said to cook for 1.5 minutes per side, we found it took about a minute longer to get the desired crust. Scallops are easy to overcook thanks to their small size, but using a meat thermometer helps determine when they reach the final temperature of 145 degrees. 

    The dinner we made was easy, impressive-looking, and delicious. We will undoubtedly purchase Costco Scallops again!

    Costco Scallops Cooking Instructions

    There are a few things to know about cooking scallops. They aren’t very big, so they cook quickly. I’m talking a little more than 2 minutes per side. They overcook easily, so use a meat thermometer to ensure they reach 145 degrees.

    Also, it’s essential to dry the scallops well to get a good sear. Yes, even though they are technically dry scallops (meaning without additives), you want to eliminate excess moisture.

    Costco Scallops FAQ

    Are Costco Scallops Wet Or Dry?

    There are two types of scallops: dry and wet. Kirkland Signature Frozen Scallops are dry scallops. 

    Molly Birnbaum explained the differences during a chat with Splendid Table.

    “Wet scallops are treated with a solution of water and sodium tripolyphosphate, or STPP, which preserves them as soon as they are harvested at sea. Then they’re often frozen. This preserves them, but it also helps them to hold on to a lot more water weight.”

    While the Kirkland Siganture Scallops are sold frozen, they are not treated with STPP. The ingredient list contains one thing: scallops. 

    The STPP makes them look glossier since they hold on to excess moisture. This extra water stops the scallops from getting a good sear when cooking. The additive also causes a soapy taste and bouncy texture. 

    How Many Scallops Should Be Served Per Person?

    A serving size for scallops is 3.5-4 ounces per person. While Costco Scallops vary in size, each one is about one ounce. Therefore, a serving is four scallops. 

    Scallops, despite their size, are hearty. We’ve found the serving size accurate.
