Preheat the air fryer: Set it to 400°F (200°C) for 3–5 minutes. A hot basket helps the salmon crisp up.
Pat the salmon dry: Use paper towels to remove surface moisture.
Dry fish equals better browning.
Oil and season: Rub each fillet with olive oil. Mix salt, pepper, garlic powder, smoked paprika, and onion powder, then sprinkle all over the fillets. If using skin-on salmon, season the flesh side more generously.
Arrange in the basket: Place fillets in a single layer, skin side down if they have skin.
Leave a little space between pieces so air can circulate.
Air fry: Cook at 400°F (200°C) for 7–10 minutes, depending on thickness. Start checking at 7 minutes. The salmon is ready when it flakes easily and reaches 125–130°F in the center for moist, medium doneness.
Rest briefly: Let the salmon sit for 2 minutes.
Residual heat finishes the cooking and keeps it juicy.
Finish and serve: Squeeze fresh lemon over the top and sprinkle with parsley or dill. Serve with rice, quinoa, mixed greens, or roasted vegetables.
