Baked Cajun Salmon Recipe Ingredients

(Note: The full list of ingredients and detailed instructions are available in the recipe card at the bottom of the post.)

You’ll need the following ingredients list to make this delicious Baked Cajun Salmon dish:

Salmon: I like to get 1.5-pound salmon filets because it fits perfectly in my cast iron skillet. I try to get an even thickness of about ½ inch from the grocery store deli so it doesn’t take a long time to cook.

Butter: The butter adds great flavor and gives the salmon a nice golden color when it is done. I used unsalted butter in this recipe. You can use olive oil as well.

Seasonings: The cajun rub consists of cajun seasoning, black pepper, garlic powder, onion powder, and paprika.

How to make this easy cajun salmon recipe:

Here are some quick visual instructions. Remember that full instructions with exact ingredients will be in the recipe card below!

  • Preheat oven to 425 degrees.

  • Rinse salmon, pat dry with a paper towel.

  • Mix seasoning blend with melted butter in a small bowl.

  • Season salmon with an even layer of the seasoning mixture on both sides. Place salmon skin side down in the bottom of a large cast iron skillet. ( You can also use a rimmed baking sheet. If you do make sure to line it with aluminum foil.)

  • Bake at 425 for 15-20 minutes on the middle position of the oven rack.

  • Remove from oven, top with parsley.

How do I store leftover salmon?

If you are worried about the salmon being done, use an instant-read meat thermometer like this one to check the temperature. When the internal temperature of the salmon reaches about 145 degrees Fahrenheit it is done.

It is recommended by USDA to cook salmon to 145° internal temperature, which is when salmon is considered fully done.

I normally remove the salmon at 140 degrees F and allow it to rest for 5 minutes before serving. During this resting period, the fish continues to cook raising the internal temperature of the salmon to the recommended 145 degrees F.

How do I store leftover salmon?

Store remaining cooked salmon in the refrigerator in a tightly covered container. Use leftovers within 3 days.

What to serve with salmon:

For this salmon recipe, I like to pair side dishes that complement the salmon like dirty rice, roasted sweet potatoes, or baby potatoes. Green beans, any variety of steamed green vegetables, or even your favorite salad recipe also go very well with tender salmon.

I’m a big fan of delicious salmon. I try different flavor varieties of salmon all the time. I make salmon in many ways but this is a favorite way of mine to make it for dinner.

Salmon is a really easy meal to make for your family. Let us know if you try this recipe in the comments below.
