Essential Ingredients for Blackened Salmon

This flavour-packed and healthy skillet meal comes together with a handful of simple pantry staples.

  • Salmon: 4 salmon fillets (about 6 oz / 170g each)
  • For the Blackened Seasoning:
    • 2 tablespoons smoked paprika
    • 1 tablespoon garlic powder
    • 1 tablespoon onion powder
    • 1 teaspoon dried thyme
    • 1 teaspoon dried oregano
    • ½ teaspoon salt
    • ½ teaspoon black pepper
    • ½ teaspoon cayenne pepper (adjust to your spice preference)
  • Fat: 2 tablespoons olive oil or avocado oil

Ingredients Notes

A little more detail on our key ingredients will ensure your blackened salmon is a spectacular success.

  • The Salmon: For the best result, it is a great idea to use salmon fillets that are of a relatively even thickness to ensure they cook at the same rate. You can use fillets with the skin on or off, depending on your preference. Patting the salmon completely dry with a paper towel before seasoning is a crucial step for achieving a perfect crust.
  • The Blackened Seasoning: Making your own homemade blackened seasoning is incredibly easy and allows you to control the flavour and spice level completely. The smoked paprika is a crucial ingredient that provides the signature deep, reddish-brown color and a wonderful, smoky flavour. You can easily adjust the amount of cayenne pepper to make the final dish as mild or as spicy as you like.
  • The Skillet: For the most authentic and best result, a heavy-bottomed cast-iron skillet is the ideal tool for making blackened salmon. Cast iron gets very hot and retains its heat evenly, which is the key to creating that beautiful, dark, and savory crust on the outside of the fish without overcooking the inside.

How to Make a Memorable Seafood Dinner

Let’s walk through the incredibly fast and simple one-pan process for creating this delicious salmon dinner.

  • Step 1: Prepare the Blackened Seasoning. In a small bowl, combine all the ingredients for the seasoning blend. Add the smoked paprika, garlic powder, onion powder, dried thyme, dried oregano, salt, black pepper, and cayenne pepper, and whisk until everything is well combined.
  • Step 2: Season the Salmon. Pat your salmon fillets completely dry with paper towels. Sprinkle the prepared blackened seasoning generously over all sides of each salmon fillet, using your hands to gently press the spices into the fish.
  • Step 3: Cook the Salmon. Heat the olive oil in a large cast-iron or non-stick skillet over a medium-high heat. Carefully place the seasoned salmon fillets in the hot skillet in a single layer, being sure not to overcrowd the pan.
  • Step 4: Sear to Perfection. Cook the salmon for about 4 to 6 minutes on the first side, undisturbed. The spices will become very dark and aromatic, creating a beautiful crust.
  • Step 5: Flip and Finish. Carefully flip the salmon fillets and cook for another 2 to 4 minutes on the second side. The salmon is done when it is cooked to your desired level of doneness and flakes easily with a fork.
  • Step 6: Rest and Serve. Transfer the cooked salmon to a clean cutting board and let it rest for a few minutes before serving. This allows the juices to settle, ensuring a tender result.

Storage Options

Leftover blackened salmon is incredibly delicious and makes for a fantastic and flavourful addition to your weekly meals. Once the salmon has cooled completely, you can store it in an airtight container in the refrigerator for up to 3 days. It is wonderful eaten cold and flaked on top of a salad, or you can reheat it gently in a skillet.

Variations and Substitutions

This simple and flavourful recipe is a wonderful template that you can easily adapt to your tastes. If you don’t have salmon, this blackened seasoning is also fantastic on other firm fish fillets like cod or mahi-mahi, or even on boneless, skinless chicken breasts. For a creamy version, you can create a simple pan sauce after the salmon is cooked by deglazing the skillet with a little chicken broth and a splash of heavy cream.

Practical & Valuable Tips

For the best result, it is highly recommended to make your own simple blackened seasoning blend; it is so much more flavourful than most store-bought versions. When you are cooking the salmon, it is very important not to overcrowd your skillet, as this will cause the fish to steam instead of getting a beautiful, dark sear. Finally, because the spices cook at a high heat, it is a good idea to have your kitchen fan on, as the process can create a little bit of delicious-smelling smoke.

Frequently Asked Questions

  1. Is “blackened” the same as “burnt”? No, not at all! The dark, almost black, color of the crust does not come from burning the fish itself. It comes from the spices, particularly the paprika, toasting and charring in the hot pan with the butter or oil, which creates an incredibly deep and delicious layer of flavor.
  2. Is this recipe very spicy? The spice level of this dish is completely customizable. As written with about ½ teaspoon of cayenne pepper, it has a pleasant, medium level of heat. If you are sensitive to spice, you can reduce or omit the cayenne, and if you are a true spice lover, you can feel free to add more.
  3. How do I know for sure when my salmon is cooked through? The salmon is done when the meat is opaque and flakes easily with a fork. The most reliable method is to use an instant-read meat thermometer. You should insert it into the thickest part of the fillet, and it should register a temperature of about 52-57°C (125-135°F) for medium.
  4. Can I make this in my air fryer? Yes, an air fryer is a fantastic tool for making blackened salmon! You would simply arrange the seasoned salmon fillets in a single layer in your air fryer basket and cook them at 200°C (400°F) for about 7-10 minutes, until they are cooked through and have a beautiful, dark crust.
  5. What are the best side dishes to serve with this blackened salmon? This flavour-packed salmon is fantastic with a variety of simple side dishes. For a low-carb meal, it is perfect with a side of cauliflower rice and a fresh avocado salsa or some roasted asparagus. It is also wonderful served with a classic side of rice pilaf or a cool, creamy coleslaw to balance the spice.
