How To Make Blackened Salmon?
- Preheat the oven: Set your oven to 380°F. Line a baking sheet with parchment paper or aluminum foil for easy cleanup.
- Prepare the salmon: Pat the salmon fillets dry with a paper towel. This step ensures the seasoning adheres well and the salmon roasts beautifully.
- Season generously: Brush the fillets lightly with olive oil. Sprinkle Cajun seasoning and brown sugar evenly over the fillets.
- Bake: Place the fillets on the prepared baking sheet. Bake for 15 minutes, or until the internal temperature of the salmon reaches 145°F. The salmon should flake easily with a fork when done.
- Serve and enjoy: Pair your blackened salmon with your favorite sides and enjoy its bold, smoky flavors.
Variations
- Blackened Mahi-Mahi: Use mahi-mahi fillets for a milder fish option with the same bold seasoning.
- Honey Glazed Blackened Salmon: Drizzle honey over the fillets before baking for added sweetness.
- Spicy Garlic Blackened Salmon: Add minced garlic and chili flakes to the seasoning mix.
- Lemon Herb Blackened Salmon: Sprinkle fresh thyme or parsley and a squeeze of lemon post-baking for brightness.
- Grilled Blackened Salmon: Grill the salmon instead of baking for a charred, smoky finish.
- Maple Dijon Blackened Salmon: Combine maple syrup and Dijon mustard for a tangy, sweet twist.
