Cajun seasoning adds a burst of flavor that creates an excellent crust right on the pan with a flakey and perfectly cooked salmon texture we all love.

What You Need
The recipe card includes the ingredient amounts and detailed cooking directions, but first, check what you’ll need to prep and make salmon with cajun seasoning, other than your favorite pan:
- 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.

How to Know When Salmon is Done
It’s important to make sure that your spicy salmon is cooked all the way. An easy way to check is to press the salmon with a fork in the thickest part of the salmon. It should flake into pieces easily, indicating that it’s done.
You can also check the salmon using a meat thermometer as well or read this full article on time and temperature of cooking salmon. If you prefer to bake it, you can use the salmon in foil method or bake cajun salmon on a sheet pan.

When you say season the top, do you mean the flesh side? Do you remove the skin at any point? Thanks!
Laura Fuentes says
Great Q! If your salmon has the skin on, season the tops as in flesh-side, is correct. If using skinless salmon fillets, then just one side would get the seasoning. I personally remove the skin after cooking since it adds flavor to the protein. I serve it directly on the plate and the salmon separates/flakes off from the skin. If you dont’ want it with skin on your plate, you can slide a spatula between the salmon and the skin. It should also separate easily.
