Enough of the chit chat.  I want you to be able to read this in less time than it takes you to make the recipe!  So below you will learn how to make blackened salmon on the stovetop or in the oven, what skillet is best, where to get your blackened seasoning mix, how you can make it dairy-free, and what side dishes go best with this blackened salmon recipe!

How to Make Blackened Salmon

In the recipe below you will see the instructions for making blackened salmon on the stovetop as well as in the oven.  My personal preference is to make it in a skillet since it gets a delightfully crisp exterior!  However, feel free to follow the instructions below to cook your salmon in the oven.

For both cooking methods you will need to:

• Select your salmon.
  • Fresh and Wild salmon is by far the best type of salmon to purchase.  Not only does it taste good, but it is also better for you.
  • Next up would be wild and previously frozen salmon.  The taste and texture are not quite as good, but the salmon is still REALLY good for you!
• Cut the salmon into filets.
  • For this recipe you should leave the skin on.  When eating, simply remove the salmon skin (leaving the fatty and good-for-you grey part!) and either discard or give to your furry friend.  (Tevah loves it when we have blackened salmon for dinner!)
• Sprinkle blackened seasoning onto the filets and rub it in.
  • See below for more information about how to make blackened seasoning from scratch and where to buy it in the store.

Skillet and Baked Blackened Salmon

To make Skillet Blackened Salmon (personal preference!):

A cast iron skillet works the absolute best when making anything blackened.  If you do not have a cast iron skillet, a large stainless steel skillet will work well, also.

Heat up a bit of butter, or dairy-free “butter”, over medium-high heat and add the salmon filets (flesh side-down).  Cook salmon for 4-5 minutes, flip, cover with a lid, and cook for an additional 4-5 minutes.

To make Baked Blackened Salmon:

Preheat oven to 450 degrees.  Line a large baking sheet with either aluminum foil or parchment paper.

Place salmon filets in a single layer, add cubed butter, and bake in preheated oven for 10 minutes.

What Internal Temperature to Cook Salmon?

Salmon is cooked through when the internal temperature reaches 145 degrees and the fish flakes easily with a fork.  This can be determined by using a simple meat thermometer and placing it in the thickest portion of the filet.

Blackened Seasoning for Salmon

You can make Homemade Blackened Seasoning (my personal preference!) or you can buy it in the store.  If purchase pre-made blackened seasoning be sure to read the label carefully.  Some of the more popular brands (Zatarain’s!) actually contains MSG while others also have added sugar, wheat, or stabilizers.

A few brands of blackened seasoning that will work well in this recipe include:

• Emeril’s Blackened Seasoning
• A Cajun Life Blackening Seasoning
• Chef Paul’s Magic Seasoning

Can I Make This Recipe Dairy-Free and Whole30?

While this easy salmon recipe is already gluten-free, low-carb, and keto friendly, you can also make it dairy-free and Whole30 compliant by using either vegan “butter” sticks or ghee.

Side Dishes to Serve with Blackened Salmon

This easy salmon recipe is already loaded with Cajun spices and is quite flavorful on its own.  My suggestions would be to serve it alongside a pretty mild side dish like these Instant Pot Mashed Potatoes, Bacon Wrapped Asparagus, Honey Oven Roasted Broccoli, or these Easy Roasted Sweet Potatoes.
