Ingredient Details
Here are the ingredients you need to make this Cajun Salmon recipe, plus some tips on a few ingredients.

Salmon – You will want to purchase 6-8 ounce fresh salmon fillets. They can be skin on or skinless.
Smoked Paprika – There are a couple varieties of paprika. You will want to make sure you have SMOKED paprika. It imparts the best smoky flavor!
Brown Sugar – When you mix brown sugar into your spice mix, make sure to break down any clumps.
Additional Spices – Garlic powder, onion powder, cayenne powder, thyme, oregano, kosher salt and pepper.
Mom’s Tip
Make sure you are getting the best flavor from your herbs and spices. Ground spices can be kept for about 6 months, whole spices can be kept for 5 years!
Step-by-Step Picture Instructions
This Cajun Salmon recipe comes together quickly. Once you make the homemade Cajun seasoning it is only about 12 minutes until dinner is ready. (which is the perfect amount of time to make roasted asparagus as a side dish!)
Preheat the oven to 400°F, make sure your oven rack is in the middle position.
WANT TO SAVE THIS RECIPE?!
Prep a baking sheet with baking spray or oil.
In a small bowl combine the seasonings and spices – brown sugar, smoked paprika, kosher salt, garlic powder, onion powder, black pepper, oregano, cayenne pepper, and thyme.

Give it a good stir so no brown sugar clumps remain.
Brush all sides of the salmon fillets with olive oil. Sprinkle the seasoning on all sides. If you have skin on salmon, just press the seasoning into the top and sides of the filets.


Place the fillets on the baking sheet and pop in the oven for 12-14 minutes, until the salmon is firm but not dry.


Mom’s Tip
If you have an instant read thermometer, pull your salmon from the oven when it reads 135 degrees Fahrenheit.
Serving
Serve immediately with a side of Cajun Aioli (recipe linked in recipe card below).

A green veggie like oven roasted asparagus or roasted broccoli and a rice side dish like dirty rice and beans, a Cajun rice or rice pilaf would be great side dishes.
Recipe Tips
- Do not overcook your salmon. You want the salmon to be flaky and moist. I recommend cooking about 12 minutes, or at 135°F internal temperature.
- Make sure your herbs and spices are full of flavor and not expired. Give them a good whiff, if you cannot smell them they should be replaced.
- Purchase quality salmon, the flesh should be shiny, moist and brightly colored.
