Step-by-Step Blackened Salmon with Cajun Cream Sauce Instructions
Step 1: Season the Salmon
Start with your salmon fillets. Season the skin side first (if skinless, choose one side). Sprinkle evenly with salt, pepper, garlic powder, onion powder, Cajun seasoning, and finish with chili powder for that signature dark color.
Flip to the presentation side and season the same way. Don’t forget to coat the sides for even flavor.
Step 2: Make the Cajun Cream Sauce
In a small saucepan, melt 3 tbsp butter. Add 1 tbsp garlic paste and 1–2 tbsp flour, stirring for 1–2 minutes to form a roux.
Mix in 1–2 tbsp lobster base and whisk until smooth.
Gradually add 2/3 cup chicken stock, whisking to remove lumps.
Stir in 1/4 cup heavy cream and bring to a simmer.
Season with Cajun seasoning, then fold in 1/2–1 cup Parmesan cheese until melted. Taste and adjust seasoning as needed. Set aside until plating.
Step 3: Sear the Salmon
Heat a skillet over medium-high heat and coat it with avocado oil. Place salmon fillets away from you, pressing down lightly for maximum surface contact.
Cook 60–90 seconds per side to form a golden crust. Add 2–3 tbsp butter and thyme, basting the salmon. Add half a lemon to the pan to infuse flavor.
Step 4: Finish in the Oven
Transfer the skillet to a 400°F oven for 6–8 minutes or until the salmon reaches 135°F internal temperature for medium doneness. Adjust time based on your preferred level of doneness.
Step 5: Plate and Serve
Spoon the Cajun cream sauce onto the plate.
Place the salmon on top and garnish with a lemon wedge and parsley. Serve immediately and enjoy the buttery, spicy, and creamy combination.
Pro Tips for the Perfect Blackened Salmon
- Match fillet sizes for even cooking.
- Don’t overcook; salmon continues to cook slightly after removing from the oven.
- High smoke point oil like avocado or vegetable oil, ensures a proper sear without burning.
- Taste the sauce before plating—adjust Cajun seasoning for your preferred heat level.
