Preheat the air fryer to 390°F.
In a medium-sized bowl, combine the butter, parsley, onion powder, seasoned salt, and garlic salt. Stir well.
Add the bread to the bowl and carefully stir to coat the bread with the seasoned butter.
Place buttered bread into the air fryer basket and cook for 5 to 7 minutes, or until the bread is toasted. Serve immediately.
