Essential Ingredients
- Fresh salmon fillets: Choose evenly-cut pieces with skin on for optimal results and better handling during cooking.
- Unsalted butter: Essential for creating the signature blackened crust.
- Spice blend: A classic mix of paprika, cayenne, garlic powder, onion powder, oregano and black pepper.
- Heavy skillet: Cast iron preferred for superior heat retention and crust development.

Cooking Method
Initial PreparationThoroughly dry the salmon fillets with paper towels to ensure proper crust formation. Apply seasoning liberally on all sides, pressing to adhere.
Butter ApplicationCoat each fillet completely with melted butter using a brush. This step is crucial for developing the characteristic blackened exterior.
Pan PreparationHeat the skillet until just smoking, typically 3-4 minutes. Proper heat level is critical for achieving the blackened effect.
Cooking ProcessCook skin-side down for 4 minutes until crispy. Flip and cook 2-3 minutes more. The center should remain slightly translucent when removed.
The technique originated in professional Cajun kitchens, where the high-heat sear followed by temperature reduction creates the perfect balance of crust and doneness.
Accompaniments
Serve alongside cool, fresh sides like cucumber-dill salad or creamy garlic mashed potatoes. For a lighter option, place over mixed greens with avocado and citrus dressing.
Spice Variations
Adjust the spice blend to taste preferences. Create a mild version without cayenne, or increase heat with additional spices. Smoked paprika offers flavor without intensity for those sensitive to heat.
Storage Guidelines
Store leftover salmon refrigerated for up to 2 days. Best used in cold preparations like salads or grain bowls. Freezing is not recommended as it compromises texture.

Professional Techniques
