Mix base: In a large bowl, combine oats, nuts, cinnamon, and salt. Stir in melted butter and honey until evenly coated.
Air fry: Spread mixture evenly in the Ninja Air Fryer Pro basket (use parchment liner if desired). Cook at 325°F for 10–12 minutes, shaking halfway through.
Cool & finish: Let the granola cool completely, it will crisp up as it cools. Stir in dried fruit or extra nuts if desired.
Store: Keep in an airtight container for up to 1 week.
Bonus Tip: For extra baklava flavor, drizzle a little honey over the cooled granola and sprinkle with crushed pistachios.
