Is Cajun Seasoning Good on Salmon?

This seasoning is PERFECT for salmon! It’s slightly spicy and a little smoky, and it pairs great with a neutral fish without overpowering its taste.

The best part is that a little Cajun seasoning goes a long way, and you can either make your own or purchase your favorite brand.

What You Need

Other than your favorite pan, here is what you’ll need to prep and make salmon with cajun seasoning:

Salmon fillets: buy this fresh or frozen from the store. If frozen, thaw before cooking.
Olive oil: for cooking and making sure it doesn’t stick to the pan. Also makes a terrific seared crust.
Salt and pepper: for seasoning.
Unsalted butter: make sure that it’s at room temperature. If you only have salted butter, you can use it but omit adding in the extra salt.
Cajun seasoning: choose your favorite brand and enjoy.

As always, check the recipe card for the ingredient amounts and detailed cooking directions.
