Wash and core the Granny Smith apples under cool water and remove the core.

Slice the cleaned apples into approximately ¼-inch thick slices and then into fry shapes.

Toss apple slices with 1 tablespoon of lemon juice to prevent browning.

In a mixing bowl, stir together ¼ cup of all-purpose flour, ¼ cup of granulated sugar, 1 teaspoon of ground cinnamon, and ¼ teaspoon of ground nutmeg.

Whisk the dry ingredients until fully combined and no clumps remain.

Melt 2 tablespoons of unsalted butter in a microwave-safe bowl.

Dip each apple fry into the melted butter, ensuring it’s coated evenly.

Toss the coated apple fries in the cinnamon-sugar mixture from Step 4.

Preheat the air fryer to 350°F (175°C) for about 5 minutes.

Place the coated apple fries in a single layer in the air fryer basket.

Cook the apple fries for 8-10 minutes, flipping halfway through.

Check for a golden brown color and cook in 1-2 minute increments if needed.

Remove the apple fries from the air fryer and cool for a few minutes.

Serve warm with optional caramel sauce or whipped cream for dipping.
