Ingredients
FOR THE BLACKENING SPICE
1 ½ tablespoons smoked or sweet paprika
1 ½ teaspoons onion powder
1 ½ teaspoons garlic powder
1 ½ teaspoons kosher salt (such as Diamond Crystal)
½ to 1 teaspoon ground cayenne
½ teaspoon black pepper
½ teaspoon dried thyme
½ teaspoon dried oregano
FOR THE SALMON
4 (6- to 8-ounce) center-cut salmon fillets, skin removed
2 tablespoons unsalted butter, melted
Lemon wedges, for serving
Preparation
- Step 1
Make the blackening spice: In a small bowl, mix the paprika, onion powder, garlic powder, salt, cayenne, black pepper, thyme and oregano.
- Step 2
Turn on the exhaust fan and heat a large cast-iron pan (or other heavy-bottomed pan) over medium-high for about 5 minutes. (If using a pan that isn’t cast-iron, your pan may heat up faster.)
- Step 3
Cook the salmon: While the pan heats, pat the salmon fillets dry with a paper towel and place on a large plate or small sheet pan. Set aside 2 teaspoons of the melted butter for serving. Brush half of the remaining butter on one side of the salmon fillets, then sprinkle half of the blackening spice evenly over that side. Using your fingers, gently press the spices on so they stick. Flip the fish, then repeat on the remaining side.
- Step 4
Adjust the heat under the pan to medium, carefully place the salmon in the hot pan and cook until the spices have darkened and the fish is cooked through, 4 to 6 minutes per side, using tongs and a thin spatula to carefully flip the fish.
- Step 5
Remove from the heat, drizzle with reserved melted butter and serve with lemon wedges.

I love the flavor of blackened seasoning on fish/seafood - cod, mahi, salmon, sea scallops. But I think the whole business of searing it in a screaming hot skillet and setting off the smoke alarms is overrated. I just do a dusting of a store-bought blackened seasoning and cook in a little butter/canola oil blend over medium heat for 2-3 minutes per side. Deglaze with a little dry white wine and let that cook down a bit and pour over the fish/scallops. Lemon wedge on the side.
Wonderful recipe. If possible, avoid farm raised Atlantic salmon. Wild-caught Alaskan sockeye is perfect for this dish (check the frozen seafood section). Keep a close eye on the fish, it will overcook in the blink of an eye. Get it out of the pan when it's almost cooked through and let it finish cooking on the plate.
I've been making faux blackened salmon for years. As a lazy man, I always use McCormick's Cajun Seasoning.
We have salmon once or twice a week but are in the midst of a kitchen renovation so our cooking options are limited to our gas grill and an air fryer. We were looking for an alternative to cedar plank salmon on the grill and tried this using the griddle insert for our grill. The results were terrific even using store bought blackening seasoning. This may be our go to for salmon from now on.
Made this, following the recipe exactly. The fish turned out lovely and moist, but it was a shame that the rub was far too salty. I think 1/3 of what the recipe calls for would likely be more than adequate.
Since I have poor ventilation, I put my cast iron skillet on an outdoor gas grill. I pulled the skillet off about 2 minutes before fish was done, so that by the time I plated mashed potatoes to go under the fillets and simple steamed/sauteed broccoli on the side, the salmon was perfect.
