You can trust my take because I shop at Costco every week and spend a whole lot of time in the kitchen testing and tasting what really works.

In this post, I’ll share why Costco frozen salmon stands out, how versatile it really is, and a few simple tips to help you turn it into dishes that feel fancy without the fuss. Whether you’re a confident home cook or just learning the ropes, this freezer-friendly favorite might just earn a permanent spot in your meal rotation.

Which Types of Frozen Salmon Does Costco Sell?

Besides the plentiful fresh salmon near the meat, Costco sells three types of frozen salmon: Kirkland Signature Farm Raised Atlantic Salmon, Morey’s Marinated Wild Alaskan Salmon, and Kirkland Signature Wild Caught Alaska Sockeye Salmon. Prices range from $20.89 to $39.79, and packages are 2.25 to three pounds. 

The three options differ in where they are caught, skin-on or off, and marinated or plain.

Here are the details on each variety. 

Wild Caught Sockeye Salmon Costco

Five types of salmon are fished from the Pacific Ocean, and Sockeye is the most popular. It has a stronger salmon taste and deeper color than other varieties. This species is smaller than other varieties and has firmer flesh.

It also has added health benefits. Kirkland Signature Wild-Caught Sockeye Salmon has fewer calories and fat than other frozen salmon at Costco. Sockeye salmon also has the highest omega-3 of any fish, approximately 2.7 grams per 100-gram portion.

These 5-7 ounce filets have no added ingredients and are sold with the skin on. Cooking salmon with the skin on helps it to retain moisture and nutrients. 

Kirkland Signature Farm Raised Atlantic Salmon

This three-pound bag of Atlantic Salmon contains individually wrapped 6-8 ounce boneless, skinless portions of salmon raised in farms on the East Coast of the United States.  Like some Costco shrimp, these filets contain salt and water as a preservative and added color. 

Salmon is the most popular fish eaten in America. Supply outpaced demand and has led to an increase in farm-raised fish. 

Morey’s Marinated Salmon

A different salmon option at Costco is Morey’s Marinated Salmon. This 2.4-pound box contains six fillets weighing six ounces each. 

This skin-on salmon is marinated in a blend of canola and olive oil, and spices. 

How to Choose Salmon

The main differences between the options of skin on or off, where it is caught and marinated or not. Here’s how to pick the right salmon for you.

Is Skin On Or Skinless Salmon Better?

Salmon provides large amounts of Omega Three fatty acids, many of which are in the skin. The skin also helps the fish retain moisture and nutrients when cooking. Skinless salmon is more likely to dry out and lose nutrients during cooking. 

The skin on salmon is preferred due to its health and cooking benefits.

The one exception is if you are pregnant or nursing, you may want to avoid eating salmon skin. Chemicals called polychlorinated biphenyls (PCBs) can be absorbed by salmon during their life through their skin and other fish they eat. PCBs are known carcinogens and have been linked to birth defects. For most other people, the benefits outweigh the risks. 

Is Wild Salmon Or Farm Raised Salmon Better?

Salmon is the most popular fish eaten in America and, just like with frozen shrimp, with rising demand, the industry has turned to farm-raised fish to keep up.  Farm-raised salmon is typically from the Atlantic Ocean, while wild-caught salmon is pulled from the Pacific. 

Whether raised on a farm or caught in the wild, salmon has many health benefits. But according to the Cleveland Clinic, “research consistently shows that there are more risks associated with farmed salmon than those pulled from oceans, lakes, and rivers.”

Marinated Or Unmarinated Salmon?

Marinated salmon makes for easy dinners. They are simple heat-and-eat meals that are perfect for busy nights.  With that convenience, you lose control of the ingredients. Morey’s Frozen Salmon Filets have a high sodium content.

Salmon is not difficult to season, and there are hundreds of wonderful recipes, so you never get tired of the same flavors. 

We recommend unseasoned filets so you can control the flavor and ingredients.

What Is The Price of Frozen Salmon At Costco

Costco frozen salmon ranges in price from $23.99 to $35.99, and packages range in size from 2.25 to three pounds. 

Comparable filets are almost double the price at local grocery stores. Costco frozen salmon is a great deal! The farm-raised version is at the cheapest price we’ve seen in three years; it’s down from a high of $33.99 while the sockeye version is three dollars more than the cheapest price.

Is Costco Frozen Salmon Worth It? What Is The Best Costco Frozen Salmon?

Costco frozen salmon is absolutely worth it!

The best frozen salmon from Costco is the Kirkland Signature Wild Caught Sockeye Salmon. 

The product has no added ingredients, and its wild-caught status means it’s likely higher in healthy omega 3s, while the skin helps the fish retain moisture and nutrients when cooked. Besides the added health benefits, Sockeye salmon has a more forward flavor than regular salmon. 

At $39.79, it’s the most expensive frozen salmon at Costco, but it’s a great deal compared to fish stores and local grocery store prices. We found a similar product for almost double the price.

Kirkland Atlantic Salmon Review

Kirkland Atlantic Salmon is not the Costco frozen salmon we recommend. While it’s an excellent price per pound, the Sockeye Salmon is only two dollars more, offering more health benefits and fewer concerns about contaminants.

Kirkland Signature Farm Raised Salmon contains a salt solution as a preservative. This addition is a concern for anyone watching their salt intake. These fillets contain more fat, calories, and cholesterol than Kirkland Signature Sockeye Salmon. 

What Is The Healthiest Frozen Salmon At Costco?

Kirkland Signature Wild Caught Sockeye Salmon is the healthiest frozen salmon at Costco. The product list just contains fish, meaning no added salt or preservatives, and studies show that wild-caught salmon has added health benefits.

The Kirkland Signature Farm Raised Atlantic Salmon is higher in calories, fat, cholesterol, and sodium. Sockeye salmon contains more protein than the East Coast species.

According to the Cleveland Clinic, farmed salmon has more concerns about contaminants, antibiotics, and pollutants, and therefore, the organization recommends buying wild caught if possible.

How To Cook Frozen Costco Salmon

Thaw the salmon in the fridge for 8-10 hours before cooking for best results.  While many claim that it’s best to cook thawed salmon, Martha Stewart insists you don’t need to defrost frozen salmon.
