1. Prepare the Filling:
- In a medium saucepan, combine the diced apples, granulated sugar, cinnamon, nutmeg, butter, and lemon juice. Cook over medium heat until the apples are softened, about 5-7 minutes.
- Stir in the cornstarch-water mixture and continue to cook for another 2-3 minutes, or until the filling has thickened. Remove from heat and let it cool completely.
2. Assemble the Turnovers:
- Roll out the puff pastry on a lightly floured surface to smooth out the seams. Cut the pastry into squares of about 5×5 inches.
- Place a spoonful of the cooled apple filling on one half of each square. Be careful not to overfill.
- Brush the edges of the pastry with the beaten egg. Fold the pastry over the filling to form a triangle. Press the edges together to seal, and use a fork to crimp the edges.
- Brush the tops of the turnovers with more beaten egg wash.
3. Air Fry the Turnovers:
- Preheat your air fryer to 350°F (180°C) for about 3 minutes.
- Place the turnovers in the air fryer basket, leaving some space between them for air circulation. You may need to cook them in batches depending on the size of your air fryer.
- Air fry for about 8-10 minutes, or until the turnovers are golden brown and puffed up. Halfway through the cooking time, flip the turnovers carefully to ensure even browning.
4. Serve:
- Let the turnovers cool for a few minutes after cooking. Dust with powdered sugar before serving, if desired.
Tips for Perfect Air Fryer Apple Turnovers
- Choosing Apples: Use apples that hold up well to cooking, such as Granny Smith or Honeycrisp, for the best texture.
- Thawing Puff Pastry: Make sure to thaw the puff pastry according to the package instructions for easy handling.
- Sealing Edges: Ensure the edges of the turnovers are well sealed to prevent the filling from leaking out during cooking.
- Cooking in Batches: Avoid overcrowding the air fryer to ensure the turnovers cook evenly and become properly crispy.
- Adjustments: Keep in mind that cooking times may vary depending on your air fryer model. Adjust as necessary, and always check for that golden brown finish.
Enjoy your air fryer apple turnovers as a delicious dessert or a sweet treat for breakfast. They’re especially good served warm, with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgent touch.
