Quick, flavorful, and effortless—this easy Baked Blackened Salmon recipe is smoky, spicy, and perfectly flaky. On the table in about 15 minutes, it’s a go-to recipe for weeknight dinners or laid-back weekend meals.
Preheat the oven to 425. Line a rimmed baking sheet with parchment paper or aluminum foil.
Combine the Cajun seasoning and brown sugar in a small bowl.
Pat the salmon filets dry and place them on the lined baking sheet. Brush each one with melted butter or olive oil. Sprinkle the brown sugar Cajun seasoning mixture evenly over the filets, then use your hands to rub it in.
Bake 10-14 minutes until it's pink and flaky, to an internal temperature of 135. Let it rest 5-10 minutes to allow carryover heat to fully cook it to 145.
Notes
How to make approximately one tablespoon of Cajun seasoning: 1 t paprika, ½ t garlic powder, ¼ t each onion powder, oregano, thyme, chili powder, cayenne pepper, salt, ⅛ t black pepper
Pat salmon dry with paper towels so the seasoning sticks better.
Adjust bake time based on thickness—start checking early to avoid overcooking.
Cook to 135°F, then let rest so carryover heat brings it to the safe 145°F.
Optional: Broil for 1 minute for a crispier top—just keep a close eye to prevent burning.
