Mix all blackening spices together.
Pat salmon dry. Brush with melted butter. Press spice mixture onto all sides of the fillets.
Air fry at 400°F for 8-10 minutes until salmon flakes easily and the spice crust is dark and aromatic.
Squeeze lemon over the top.
Serve with rice, grilled vegetables, or a fresh salad.
Tip: The butter helps the spices form a crust and prevents burning. The crust should look very dark — that's char, not burnt. Skin-on fillets work best: cook skin-side down and don't flip. The cayenne is the heat — adjust to your preference.
