Pat the salmon filets dry.
Drizzle olive oil over the tops and sides, then sprinkle evenly with blackened seasoning, gently pressing it into the fish.
Place the salmon in the air fryer basket, skin side down.
Air fry at 390°F for 8 to 10 minutes, or until the salmon reaches an internal temperature of 145°F and flakes easily with a fork.
Serve hot with lemon wedges and optional parsley.
