Creating Blackened Salmon with Creamy Dijon Sauce is simple if you follow these steps:

1. Prepare the Spices: In a small bowl, mix together the smoked paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper. This will be your seasoning blend.

1. Season the Salmon: Pat the salmon fillets dry with paper towels. Rub each fillet generously with olive oil. Then, sprinkle the seasoning mix evenly over both sides of the salmon.

1. Heat the Pan: Place a large cast-iron skillet over medium-high heat and allow it to get very hot. This step is crucial for achieving that perfect blackened crust.

1. Cook the Salmon: Once the skillet is hot, add the seasoned salmon fillets. Cook for about 4-5 minutes on each side until the salmon is cooked through and has a blackened crust. Adjust the heat as necessary to avoid burning.

1. Make the Creamy Sauce: While the salmon is cooking, whisk together the mayonnaise, Dijon mustard, and lemon juice in a separate bowl until smooth and creamy.

1. Plate the Dish: Remove the salmon from the skillet and let it rest for a minute. Then, place each fillet on a plate and drizzle the creamy Dijon sauce generously over the top.

1. Garnish: If desired, sprinkle chopped fresh parsley over the salmon for a pop of color and flavor.

1. Enjoy: Serve immediately while the salmon is hot and the sauce is creamy. Pair with your favorite sides.
