Preheat the air fryer: Set it to 400°F (200°C) for 3–5 minutes.
A hot basket helps the salmon crisp and prevents sticking.
Prep the salmon: Pat fillets dry with paper towels. Dry surfaces brown better and keep the fish from steaming.
Season: Rub each fillet with olive oil. Sprinkle salt, pepper, garlic powder, and paprika evenly.
Zest a little lemon over the top for brightness.
Basket setup: Lightly spray the basket or use a perforated parchment liner. Place salmon skin-side down, leaving space between fillets.
Cook: Air fry at 400°F for 7–10 minutes, depending on thickness. Start checking at 7 minutes.
The salmon should flake easily and read 125–130°F in the center for medium.
Finish: Let rest 2 minutes. Squeeze fresh lemon over the top. If using, brush with a quick mix of Dijon and honey for a glossy finish.
Serve: Pair with a side salad, roasted asparagus, quinoa, or buttery mashed potatoes.
