What Is Blackened Salmon?
Blackened salmon is salmon coated in a flavorful spice blend and cooked over high heat until a dark crust forms on the outside. Despite the name, the salmon is not burned. The “blackened” appearance comes from the spices caramelizing and creating a rich smoky crust.
This Cajun cooking technique works especially well with salmon because the rich fish balances the bold seasoning beautifully.
Ingredient Notes
Salmon
Fresh salmon fillets work best for this recipe. Skin-on salmon helps hold the fillets together during cooking while adding extra flavor and texture.
For the best flavor, look for high-quality wild-caught salmon such as sockeye, coho, or king salmon. Sockeye salmon is especially delicious in this blackened salmon recipe because its rich flavor and firm texture hold up beautifully to the bold seasoning blend.
Best Wild Salmon Varieties
Sockeye Salmon
Sockeye salmon has a deep red color, rich flavor, and firm texture that works perfectly for blackened salmon.
Coho Salmon
Coho salmon is slightly milder and more delicate while still offering that classic wild salmon flavor.
King Salmon (Chinook)
King salmon is rich, buttery, and incredibly luxurious thanks to its higher fat content.
Pink Salmon
Pink salmon is lighter and milder in flavor, making it a great affordable option for weeknight dinners.
Paprika
Paprika adds smoky flavor and gives the salmon its signature deep color. Smoked paprika can be used for even more smoky flavor.
Cayenne Pepper
Cayenne adds heat to the seasoning blend. Adjust the amount depending on your spice preference.
Garlic Powder and Onion Powder
These pantry staples create the savory foundation of the blackened seasoning.
Dried Herbs
Thyme, basil, and oregano balance the smoky spices with earthy flavor.
Lemon Dill Sauce
This salmon pairs beautifully with my Lemon Dill Sauce recipe. The creamy lemon sauce cools the spice from the blackened seasoning while adding fresh citrus flavor and brightness.
Serve the sauce drizzled over the salmon or on the side for dipping.

Tips for the Best Blackened Salmon
- Pat the Salmon Dry: Dry salmon helps the seasoning stick better and creates a crisp crust when seared.
- Use a Hot Cast Iron Skillet: A properly heated skillet is essential for achieving that classic blackened crust.
- Start Skin-Side Up: Cooking the salmon skin-side up first helps develop a beautiful crust on the presentation side of the fish.
- Don’t Move the Salmon: Let the salmon cook undisturbed while the crust forms.
- Don’t Overcook: Salmon cooks quickly and is best when still slightly translucent in the center.
