Costco Argentine Shrimp (Lobster Like) + How to Cook

Costco Wild Argentine Red Shrimp - Kirkland Signature

Kirkland Signature Argentine Red Shrimp at Costco

I was strolling through Costco the other week, and I noticed that they had an unannounced sale on their Frozen Kirkland Signature Argentine Red Shrimp.

I wasn’t familiar with Argentine Shrimp, but I don’t mind regular shrimp, and I figured there’s no better time to try something than when Costco has it on sale, so I pulled the trigger on the 2-pound bag.

I found the Wild Argentine Red Shrimp in the frozen food aisles near the other frozen shrimp, the garlic butter shrimp, and the frozen salmon

Wild Argentine Red Shrimp from Costco is sold raw, peeled, deveined, and with tail off. There are no added preservatives or chemicals, and there are 10-30 shrimp per pound.

Argentine Shrimp Vs. Common Shrimp

After some research, I did find out what the difference is between these wild Argentine red shrimp and the common shrimp that Costco sells. 

The first big difference is that these shrimp are caught in the South Atlantic Ocean and, in particular, are caught off the coast of, you guessed it, Argentina. This ecosystem and coastal water are what make this shrimp so special.

Their nutrient-rich environment gives the Argentine Red Shrimp the beautiful red color they are known for. Just looking at the bags of shrimp in Costco’s frozen food aisles, you can easily see the difference in color between these Argentine Red Shrimp compared to the gray color of Costco’s other frozen shrimp. 

In addition to their appearance, Wild Argentine Red Shrimp possess a distinctive delicate texture that sets them apart. Their taste is slightly sweet with a decadent flavor similar to lobster, adding an extra touch of indulgence to your meal.

Costco Argentine Red Shrimp Raw

The Wild Argentine Red Shrimp are also known for their size, reaching lengths up to 8 inches, but Costco’s bag of Argentine Shrimp had a variety of sizes. 

Some were pretty hearty, while others were definitely on the smaller end.

Costco Cost Comparison

Costco retails their 2-pound bag of Wild Argentine Red Shrimp for $21.49 or $10.75 a pound. This is definitely more expensive than 2 pounds of Costco’s regular frozen shrimp (21-25 shrimp per pound), which sells for $15.99 or $8.00 per pound.

At retail, you are looking at about $2.75 extra per pound for Argentine Red Shrimp.

Costco Argentine Shrimp Frozen

I purchased the Wild Argentine Red Shrimp when Costco discounted the price by $4.50, bringing the price down to $16.99. 

This drops the per pound price down to $8.50, which is a more than fair price and easily worth the premium over Costco’s other frozen shrimp.

Argentine Shrimp Taste Test

I followed my simple garlic butter recipe for cooking these Argentine Shrimp, and everything came out amazingly. 

The shrimp were cooked perfectly (hard to do for me), and they were delicious. The shrimp were moist and perfectly tender, with a little sweetness that paired well with the garlic butter.

The packaging describes the Kirkland Signature Argentine Shrimp as having a lobster-like flavor, which I thought would be a bit of hyperbole, but actually wasn’t too far off the mark. 

It’s obvious when we were eating it that it wasn’t lobster, but I can see how many people would say it tastes and feels like lobster. I would probably classify it as “shrimp +” rather than lobster, but the comparison is fair.

Overall, I thought the Argentine Shrimp were delicious and well worth it. The flavor was there, and it was easily the best shrimp meal I have had in quite a while. 

I usually have a hard time justifying a premium product like this, but I can see myself splurging on these rather than purchasing regular shrimp.

User Ratings and Reviews

It's very good!
these taste great - just soak in cold water to defrost and cook - they are wild-caught which is the only fish I'll eat. no shelling or de-veining.
The packaging indicates the shrimps are raw. It then goes on to say you can eat them cold in a prawn cocktail. The instructions says to sauté or grill. As for me I don’t think the instructions are clear enough in stating that you can eat raw or must be cooked. I have prepared eight plates as a shrimp cocktail and a banded them at last minute as I became unsure and didn’t want to risk making my guests I’ll.
This is the most pointless ad ridden drivel. It tells you the same stuff that's on the package but in 500% more words that NO ONE CARE TO READ - WE ALREADY SAW THE PACKAGE.
