Bold Cajun Air-Fryer Salmon
When I want salmon with some attitude, this is the one. You press a cajun rub with a little brown sugar onto the fillets, preheat the air fryer so the edges blacken, and about ten minutes later you have flaky salmon with a bold, sweet-heat crust. No glaze to fuss with, and the air fryer keeps your kitchen from smelling like a fish fry. The only rule is do not overcook it. Pull it a few degrees early and let it rest, and it stays moist.
Why this one is so easy
Bold, blackened-style flavor with a sweet-heat crust, done in about ten minutes of cooking.
The air fryer keeps the smell contained, so no lingering fishy kitchen.
No glaze, no fuss. A quick dry rub does all the work.
Della's tips
Pat the fillets dry before oiling. A dry surface chars, a wet one steams.
Preheat the air fryer so the crust sets and the edges blacken a little.
Do not flip, and do not wrap in foil. Foil traps steam and stops the crust from forming.
Use a thermometer and pull it 5 to 10 degrees early. Carryover heat keeps cooking it as it rests.
Make it your own
+ Extra spicy: add a quarter to half teaspoon of cayenne or a pinch of red pepper flakes.
+ Deeper crust: bump the brown sugar to 2 tablespoons for more caramelized blackened edges.
+ Milder: cut the cajun to half a tablespoon and skip the cayenne. The paprika and sugar still give color and flavor.
If you are out of something
Avocado oil or melted butter in place of the olive oil.
Old Bay instead of cajun for a milder Gulf-Coast angle.
The same rub works on other thick fillets like cod or trout, just adjust the time for thickness.
Salmon is best cooked fresh and served right away. You can mix the dry rub days ahead and keep it in a jar, and season the fillets up to a few hours ahead, covered in the fridge. Leftovers keep three days and reheat gently at 350F for a few minutes, knowing the texture firms up. I would not cook it ahead and hold it.
Ingredients
Steps
Pat the salmon really dry. A dry surface takes the rub and chars instead of steaming.
Brush the fillets with oil. Mix the cajun seasoning, brown sugar, garlic powder, and smoked paprika, and press it onto both sides. Go easy on extra salt, since cajun blends are already salty.
Preheat the air fryer to 400F for 5 minutes so the crust sets and the edges get a light char. Lay the fillets skin-side down in a single layer. In a 6-quart basket that is 2 fillets at a time.
Air fry at 400F for 8 to 10 minutes, no flipping. Pull them at 125 to 130F for moist, just-flaking salmon, or 145F for the USDA temp. Do not overcook, that is the one thing that dries it out.
Rest 2 to 3 minutes, then finish with parsley and a squeeze of lemon.
