How to Make Costco Salmon Better? [8 Magical Tips & Tricks]

How to Make Costco Salmon Better
Share on:

I’ve never considered myself a good judge of salmon, as it has to be very bad for me not to like it. However, I do think of myself as relevant when it comes to Costco salmon because it is unmistakably delicious, and when I tell you it’s worth every chance, I’m definitely right. Still, there are things you can do to make it even better and enjoy it even more. So, how to make Costco salmon better? 

Add lemon, glaze, herbs, an oil and vinegar mixture, as well as spices to significantly elevate your Costco salmon experience. Serve it with sauce and grill instead of baking it to improve its flavor.

When it comes to Costco salmon, it’s hard for me to be objective because I simply love the delicious, rich, and buttery fish. However, why not make a delicious fish taste even better with a few simple tricks? In this article, I’ll share some ideas with you on making Costco salmon better. 

Add Lemon 

You probably know that lemon and fish go perfectly together, and it is only fitting that we open our list with this idea. Costco salmon is very receptive to the lemon flavor allowing each drop to penetrate and alter the taste. You put lemon wheels on top of the salmon and bake, or do as I do and let the salmon marinate in lemon juice for about 20 minutes before baking it. 

The lemon will add a bit of a sour and citrusy note to the salmon but will also bring out the salmon’s natural butteriness.

Add Herbs 

Herbs are always a good idea when it comes to Costco salmon. What I like to do is add them midway through baking. If you add them before you bake the salmon, they will lose most of their flavor, and adding them after the salmon finishes baking won’t give them enough time to release flavor. 

So, I’ve found that the perfect timing is to sprinkle the herbs in the middle of baking. I like to add basil, rosemary, and Italian mix while the salmon bakes and top it with fresh parsley after it’s done. Still, you can do as you prefer; it will still turn out well. 

Glaze It

Add lemon herbs or glaze to Make Costco Salmon Better

Costco salmon does great when glazed. This buttery and rich fish gets even richer, even decadent, when glazed. Make a mixture of honey, soy sauce, and garlic, and brush the salmon with it. 

I prefer letting the salmon soak in the mixture to absorb the flavors, but brushing it with the glaze will also do. After glazing the salmon, bake it and enjoy the tender and juicy meat, tasting like heaven!

Use an Oil and Vinegar Mixture 

If you can’t think of anything or are too lazy for something more demanding, bake the Costco salmon and brush it with a mixture of oil, vinegar, parsley, and garlic. It is very easy to make, and you just mince the garlic and mix it with the rest of the ingredients. 

The amounts you use are totally up to you, but I would be careful with the vinegar and add it little by little. You can also add salt and pepper to the mixture to make it even more flavorful. Enjoy!

Spice It Up 

If you are a fan of spicy food, turn your Costco salmon into a spicy delight. The spices I usually use are cayenne pepper and chili flakes but feel free to use any spices you think might work. 

Curry and powdered garlic, turmeric, and paprika do nicely here. Saffron is also a great addition here, as well as cloves, but add both while baking and not after.  

Serve with Sauce

Even though you probably serve your Costco salmon with some kind of side, I recommend you introduce a sauce as well. Salmon goes great with sour sauces, such as tzatziki or tartar sauce, so make a generous amount of these creamy delights and make yourself a finger-licking meal. 

Grill It 

Last on our list, but certainly worthy of every chance, grilling your Costco salmon might just do the trick if nothing else does. Grilling your salmon results in a different taste and texture of the fish. It will be sharper and more intense-flavored but a bit drier too. Still, it is worth a try, as the salmon is really delicious. 

I like my salmon more on the juicy side, so I don’t use this method very often, but feel free to try it if it fits your taste.
