01 - In a medium mixing bowl, gently combine the diced mango, red bell pepper, finely chopped red onion, minced jalapeño, and fresh cilantro. Stir in the lime juice and season with salt to your preference. Allow the salsa to meld while preparing the salmon.
02 - In a small bowl, thoroughly whisk together the smoked paprika, garlic powder, onion powder, dried thyme, dried oregano, cayenne pepper, ground black pepper, and salt to create the blackening spice blend.
03 - Gently pat the salmon fillets completely dry with paper towels. Lightly brush both sides of each fillet with olive oil.
04 - Generously sprinkle the prepared blackening spice blend over both sides of each salmon fillet, pressing lightly to ensure the seasoning adheres well.
05 - Place a large cast iron skillet or heavy-bottomed nonstick pan over medium-high heat. Add a small amount of olive oil, just enough to thinly coat the bottom of the pan.
06 - Carefully place the seasoned salmon fillets into the hot skillet, flesh-side down (if skin-on, place skin-side up first). Sear for 3 to 4 minutes, allowing a rich, dark crust to form. Flip the fillets and continue cooking for an additional 3 to 4 minutes, or until the salmon is cooked through and flakes effortlessly with a fork.
07 - Transfer the cooked salmon fillets from the pan to a plate and allow them to rest for 2 minutes before serving.
08 - Serve the blackened salmon immediately, garnished with a generous spoonful of mango salsa and fresh lemon wedges on the side.
