Step-by-Step Instructions
- Prepare the Blackened Seasoning:
- In a small bowl combine paprika garlic powder onion powder thyme oregano cayenne pepper salt and black pepper making sure the blend is evenly mixed with no lumps for consistent flavor across every bite
- Season the Salmon:
- Pat each salmon fillet dry thoroughly this is key for a perfect sear Drizzle olive oil evenly over both sides of every fillet then use your hands to press the spice mix onto all surfaces The spices should stick well for a bold crust
- Cook the Salmon:
- Heat a heavy skillet such as cast iron on medium-high until it is very hot Add the salmon fillets skin side down first and leave them untouched so the skin crisps after four to five minutes use a spatula to carefully flip and finish cooking until just cooked through with a crisp blackened exterior Test for doneness by gently pressing the fillet it should flake but still look moist inside
- Make the Creamy Dijon Sauce:
- Mix mayonnaise Dijon mustard lemon juice honey garlic powder salt and black pepper in a small bowl Stir until it becomes completely smooth and taste to see if you want to adjust any flavors You can make this ahead and let it chill to let the flavors mingle
- Serve:
- Transfer salmon to plates and immediately spoon a generous amount of the Dijon sauce over each piece Top with a sprinkle of fresh herbs or a wedge of lemon if you have them ready
- Enjoy:
- Pair with your favorite quick sides like roasted veggies warm rice or a crisp salad This meal really shines when everything comes to the table hot and the sauce is cool and creamy

The rich flavor of the blackened crust always feels special in my kitchen I have a soft spot for Dijon mustard since it reminds me of big family dinners growing up that always seemed to feature a tangy mustard sauce over fish
Storage Tips
Store leftover salmon in an airtight container in the fridge for up to two days To enjoy again reheat on low heat in a skillet or in the oven loosely covered so the crust stays crisp The Dijon sauce should be stored separately and stirred before serving
Ingredient Substitutions
If you do not have salmon any firm fish like cod tilapia or steelhead trout works beautifully Greek yogurt can replace mayo in the sauce for a lighter twist If you like more smoke try smoked paprika instead of cayenne and paprika
Serving Suggestions
Serve this dish over fluffy rice with steamed broccoli or a fresh salad For something different try tucking the salmon into warm tortillas with crunchy cabbage for blackened salmon tacos with extra Dijon sauce drizzled on top

Cultural and Historical Context
Blackening fish is a tradition that comes from Cajun and Creole roots where bold spices and hot pans were used to create deep flavor I love pairing this style of salmon with Dijon sauce which is inspired by classic French flavors bringing two great food traditions together in one fast weeknight dinner
