In a large mixing bowl, combine the rolled oats and almonds. Stir to distribute evenly.
In a small microwave-safe bowl, melt the coconut oil if solid. Add the honey, granulated sugar, brown sugar, vanilla, cinnamon, and salt. Stir until fully combined.
Pour the wet mixture over the oats and almonds. Stir thoroughly until everything is evenly coated. Make sure no dry oats remain at the bottom of the bowl.
Line the air fryer basket with parchment paper. Spread the granola mixture into an even, thin layer. Do not overcrowd—cook in batches if necessary.
Air fry at 320°F (160°C) for 5 minutes.
Open the basket and stir the granola thoroughly to prevent hot spots and over-browning.
Continue air frying for 3–5 more minutes, stirring once more halfway through, until lightly golden and fragrant. Watch closely during the last few minutes.
Remove the basket and let the granola cool completely without stirring. This allows it to crisp up and form clusters.
