Costco Kirkland Signature Tilapia Loins Review

Is Costco Kirkland Signature Tilapia healthy? Why does tilapia have such a bad reputation?

Costco Kirkland Signature Tilapia Loins

Another Costco fish review! Today I’m reviewing the Costco Kirkland Signature Tilapia Loins. I picked this up thinking the tilapia loins look healthy and are a reasonable price. After a bit of google searching I discovered tilapia has a bit of a bad reputation on the internet!

Other Costco fish reviews on the blog are the Costco Kirkland Signature Atlantic Cod, High Liner Miso Glazed Cod, AquaStar Lemon & Cracked Pepper Cod, Trident Wild Pacific Salmon Burgers, Kirkland Signature Mahi Mahi and High Liner English Style Battered Pacific Cod.

You can find the Costco Kirkland Signature Tilapia Loins in the freezer section by the other frozen fish. The item number is 1139689.

Tilapia is a light, flaky, mild-flavored white fish. It’s texture is much firmer/denser than cod or salmon. I find the Kirkland Signature Tilapia Loins don’t have a fishy smell when cooking it or taste at fishy. Sean my husband appreciated the lack of fishy smell in our house!

The tilapia really doesn’t have too much flavor but I tried a few bites that tasted like lake water so despite the tilapia loins not being at all fishy, they did taste a bit….dirty, musty and earthy. I used salt & pepper to season my tilapia loin and imagine you can use all sorts of seasonings and sauces on tilapia.

I paid $21.49 Canadian for the 1.36 kg bag of tilapia that has eight to 12 tilapia loins in it. How many loins you get in the bag depends how big your loins are but each loin is 113-213 grams.

Costco Kirkland Signature Tilapia Thawing Instructions


Each tilapia loin is individually vacuum-packed in plastic so you can easily take out one single portion to thaw overnight. Once thawed the package states the tilapia needs to be consumed within two days.

Do not refreeze the tilapia and keep your Costco tilapia in the freezer until you’re ready to eat it.

You can choose to bake, saute or grill the tilapia and cooking instructions are on the bag. Tilapia is great for fish tacos, to be served as “fish and chips” or even used in a stir-fry.

The best before date listed on my bag of tilapia is 14 months from the date I purchased it.

Costco Kirkland Signature Tilapia Loins Nutrition Facts
Costco Kirkland Signature Tilapia Loins Nutrition Facts


Initially when I look at the nutrition information I think “this is super healthy”. The only ingredient listed is tilapia and one whole portion is 21 grams of protein, zero grams of fibre, sugar and carbohydrates, 35 mg of sodium one gram of fat and 110 calories.

This is a low calorie, high protein, low fat option.

So then why do some people think tilapia is unhealthy?

Through my research I found that tilapia has an unbalanced omega-6 fat to omega-3 fat ratio. Meaning it has very little omega-3 fatty acids (what salmon has that makes it so healthy) and high omega-6 fatty acids, omega-6 is believed to cause inflammation that can lead to heart problem and arthritis.

Also tilapia is usually farmed and some farms feed tilapia an unhealthy diet consisting of corn and soy instead of lake plants. Farms are also known to keep them in extremely cramped conditions where disease can spread easily.

There’s also concern that tilapia farmers use antibiotics and additives. As well farming tilapia can be seen as harmful to the enviornment because if tilapia escape the area they’re farmed in they can contaminate the water and spread disease to the wild fish in the area.

Are Costco Kirkland Signature Tilapia Loins healthy?

The good news is that the Kirkland Signature Tilapia Loins are from Indonesia and Indonesia is known for it’s ethical and eco-friendly tilapia farming.

Tilapia from Indonesia are the first farmed fish to meet the Aquaculture Stewardship Council certification standard. This means the fish are responsibly farmed, no bad diets are antibiotics and enviornmental impacts are minimized.

The Costco tilapia loins are lake grown and raised without the use of antibiotics. In my opinion tilapia isn’t unhealthy as long as you’re getting it from a reputable source like Costco.

Tilapia is low in calories, has a ton of protein, is also a good source of vitamin B12, potassium and niacin. If you’re concerned about the ratio of omega-6 to omega-3, just be aware that a lot of healthy foods like nuts and seeds (which I think are extremely healthy) are loaded with omega-6 fatty acids.

Give it a try!

If you’ve had tilapia before and don’t mind a bit of an earthy flavor I think this is a mild tasting, versatile, non-fishy, reasonably priced white fish.

Have you tried this tilapia? What did you think?

  1. Is this still accurate info as to the source of fish? I scanned the qr code on bag and window popped up saying this page was no longer available.

  2. I too, thaw in warm water. Dredge in seasoned flour (Lemon, Pepper, Sea Salt, Parsley, Garlic) saute till brown in 1/2 butter & Olive Oil, toss in a few slices of fresh lemon or a splash of lemon juice. Yum.

  3. Have had multiple times I blacken using home made spice recipe from internet. Do in black iron pan covered 3 min per side, comes out great.

  4. Had it for the first time tonight and it tastes nothing like other tilapia I’ve had – in a good way. Other tilapia I’ve had is much earthier, this is a much more delicate flavor and I more flakey, almost cod like in texture. It was great when I baked it in a parchment envelope with cherry tomatoes, sliced garlic, olives, capers, thyme, a dab of butter, a dash of olive oil and a fluffy of white wine.

  5. Tilapia from Costco must be seasoned to have any taste. That said, tilapia from other vendors usually come from China or Morocco. Better taste but unsafe.

  6. We’ve used the tilapia from Costco for quite a few years. I thaw the plastic wrapped fillets in warm water for a few minutes to soften them. Then I sprinkle them with lemon pepper and microwave them, covered, until the internal temperature is 145F or over. They are delicious, and not mushy at all.

  7. is costco talapia genetic engineer (GE)? Because its labelled Aquaculture Stewardship Council (ASC) certified this is also included GE aquafarming fish is qualified!

  8. I think it is great. I bake in the oven at 450′ for 4 minutes remove spread seasoning mixture of Mayonaise, salt, pepper, cayenne pepper, seasoning salt, garlic powder, garlic salt. Then bake for another 8 minutes.

  9. LOVE LOVE Kirkland Talapia loins and haven’t been able to get them for over a year at our local costco.We cook them frozen in oven on parchment lined cookie sheet ,with sea salt ,ground pepper baste with season butter every & flip every 10 for total of 30 min at 400

  10. I’m not a fish lover but trying to get more in our diet. Used this recipe on some fresh walleye which I think would work on any white fish. If you enjoy Asian flavours this is great. Fish is even better cold on salad or just snacking
    Lay fillets on foil
    Rub on sesame oil and soy sauce. A bit of oil on each. Sliced or diced fresh ginger and a splash of oil. Green onion if u have it. We didn’t. Fold up pouches and bake on a tray at 400 for 10 minutes depending on thickness. Let packets sit for 10 minutes or so. Makes a lovely sauce for rice or veg

    Sorry this has no relevance to the tilapia but was a game changer for us. We were always frying the fish. Oh Fishcrisp I miss you so
