Pat the salmon fillets dry with kitchen paper to remove excess moisture, which helps the spice adhere and crisp better.
In a small bowl, mix the Cajun spice with a pinch of salt and black pepper to enhance flavor.
Rub the spice mixture evenly all over the salmon fillets, pressing gently to ensure the spices stick to every surface.
Lightly drizzle the olive oil over the seasoned salmon or spray with a cooking spray to help develop a crispy crust.
Preheat your air fryer to 400°F (200°C) for about 3 minutes so it’s hot and ready to cook.
Carefully lay the salmon fillets skin-side down into the hot air fryer basket, spacing them apart for even cooking.
Cook the salmon for 8-10 minutes, listening for the sizzle and crackle as the spice crust forms and turns golden brown.
Once cooked, use tongs to carefully remove the salmon from the air fryer and transfer to a serving plate.
Squeeze fresh lemon juice over the hot salmon to brighten the smoky flavors and add a refreshing note.
Garnish with chopped parsley or chives if desired, adding a pop of color and freshness.
Serve immediately with your favorite sides—crispy vegetables, rice, or a simple salad make excellent accompaniments.
