Cajun Blackened Salmon with Avocado-Corn Salsa (20-Minute, Gluten-Free)
Crisp, charred edges meet a moist, flaky interior while a vibrant avocado-corn salsa adds creamy, sweet and tangy contrast. The pan-seared blackening spice forms a smoky crust that highlights the salmon's natural richness and holds up to bold toppings.
Swap or adjust the spice blend to taste: reduce cayenne for milder heat or use smoked paprika for deeper smokiness. Frozen corn works well—quickly thaw in a sieve under warm water and drain. For a dairy-free option keep the recipe as written; to add creaminess serve with a dollop of Greek yogurt or crème fraîche.
Serve this with quick-cooked rice, quinoa, or a green salad for a light weeknight meal, or tuck the salmon into warm tortillas for fish tacos at casual gatherings. Leftovers keep for 1–2 days; reheat gently in a low oven or enjoy cold over greens for a fast lunch.
How to Make It
-
1
Make the blackening spice: combine smoked paprika, paprika, garlic powder, onion powder, dried oregano, cayenne, salt, and black pepper in a small bowl.
-
2
Pat salmon dry with paper towels and rub both sides with 1 tbsp olive oil. Generously press the blackening spice onto the top side of each fillet.
-
3
Heat a large heavy skillet (cast-iron preferred) over medium-high heat until very hot, then add the remaining 1 tbsp olive oil and swirl to coat.
-
4
Place salmon fillets spice-side down in the skillet. Cook without moving 3–4 minutes until a dark crust forms. Flip and cook 2–4 minutes on the other side until internal temperature reaches 56–60°C (133–140°F) for medium doneness, or cook a bit longer for well done. If using skin-on, start skin-side down and crisp skin first.

5
While salmon cooks, assemble the salsa: in a medium bowl combine diced avocado, corn kernels, finely chopped red onion, minced jalapeño, chopped cilantro, lime zest and juice, honey, and a pinch of salt. Toss gently to combine.
-
6
Transfer salmon to a plate and, if using, dot each fillet with a small amount of butter to melt over the warm fish.
-
7
Serve salmon topped with avocado-corn salsa alongside cooked rice or a bed of greens. Squeeze extra lime over the top if desired.
