Blackened salmon is a bold and flavorful dish that originates from the Southern United States, particularly Louisiana, where Cajun and Creole cuisines shine. The “blackening” technique involves coating fish with a robust spice mix and searing it in a hot skillet, creating a beautifully charred crust while keeping the inside tender and juicy.
This dish is popular for its smoky, spicy flavor, ease of preparation, and visual appeal. Whether served with rice, veggies, or salad, blackened salmon is both restaurant-worthy and simple enough for a quick weeknight dinner.
Ingredients
For the Salmon:
-
4 salmon fillets (6 oz each, skin-on or skinless)
-
2 tablespoons olive oil or melted butter
Blackening Spice Mix:
-
1 tablespoon paprika (smoked preferred)
-
1 teaspoon garlic powder
-
1 teaspoon onion powder
-
1 teaspoon dried thyme
-
1 teaspoon dried oregano
-
½ teaspoon cayenne pepper (adjust to spice preference)
-
½ teaspoon ground black pepper
-
½ teaspoon salt
Optional Substitutions:
-
Olive oil: Use avocado oil, ghee, or vegan butter.
-
Salmon: Try trout or mahi-mahi as alternatives.
-
Low spice: Reduce cayenne or omit for milder flavor.
Step-by-Step Cooking Instructions
-
Prepare the spice mix:
Combine all spices in a bowl and mix thoroughly. -
Prep the salmon:
Pat salmon dry with paper towels to ensure a good crust. Rub both sides with olive oil or melted butter. -
Season generously:
Coat each fillet with the blackening seasoning, pressing it into the fish to adhere well. -
Heat the pan:
Use a cast-iron skillet or heavy-bottomed pan. Heat it over medium-high heat until very hot but not smoking. -
Sear the salmon:
Place salmon flesh-side down in the hot skillet. Cook for 3–4 minutes without moving it. -
Flip and finish:
Flip gently and cook the skin-side for another 3–4 minutes, depending on thickness. Internal temp should reach 125–130°F (52–54°C) for medium. -
Rest and serve:
Let salmon rest for 2 minutes before serving to retain juices.
Avoid These Mistakes:
-
Don’t overcrowd the pan—cook in batches if needed.
-
Don’t use a nonstick pan—it won’t develop the proper crust.
-
Don’t overcook—it dries out quickly.
Pro Tips and Cooking Techniques
-
Use cast iron for best sear and crust formation.
-
Butter adds richness and enhances the spice blend—try brushing it on during cooking.
-
Ventilate well—blackening produces smoke.
-
Dry fish thoroughly before seasoning to avoid steaming instead of searing.
