Ingredients Needed
Filling:
- 10 medium Granny Smith apples, peeled, cored, and sliced
- 6 tbsp water
- 6 tbsp (85g) unsalted butter, room temperature
- 1 cup (200g) granulated sugar
- 3 tbsp cornstarch (cornflour)
- 4 tsp ground cinnamon
- ¼ tsp ground nutmeg
Puff Pastry:
- 1 sheet frozen puff pastry, thawed according to package directions
- 1 large egg, beaten
How To Make Apple Pie Puff Pastry
- Preheat the oven: Preheat to 400°F (200°C). Place a baking sheet or pan under the skillet to catch drips.
- Cook the apples: In a large pot over high heat, add the sliced apples and water. Cook for 6 minutes, stirring occasionally. Add the butter and stir until melted.
- Mix the dry ingredients: In a bowl, whisk together the sugar, cornstarch (cornflour), cinnamon, and nutmeg.
- Thicken the filling: Add the sugar mixture to the pot. Stir constantly for 2 minutes, or until the sauce thickens. Remove from heat and set aside.
- Prepare the puff pastry: Lay the puff pastry sheet on a clean surface. Brush with the beaten egg. Cut into 16 equal-sized squares.
- Assemble the pie: Pour the apple mixture into a 10-inch (25 cm) cast iron skillet. Arrange the puff pastry squares over the apples in a circular, overlapping pattern, covering as much of the filling as possible.
- Bake: Bake for 27-30 minutes, or until the pastry is golden and the filling is bubbly.
- Cool and serve: Let the pie rest before serving.

Recipe Tips
- Use the right apples: Granny Smith apples work best because they hold their shape and have a nice tart flavor that balances the sweetness. Avoid soft apples like Red Delicious, as they can turn mushy.
- Cook the filling properly: Stir constantly when adding the sugar mixture to prevent lumps. The sauce should be thick and smooth before removing it from heat.
- Keep the puff pastry cold: If the pastry gets too warm, it won’t puff up properly. If needed, place it in the fridge for a few minutes before cutting and layering.
- Don’t skip the egg wash: Brushing the puff pastry with a beaten egg gives it a beautiful golden color and a crisp texture after baking.
- Let it rest before serving: The filling will be extremely hot straight out of the oven. Let it cool for at least 10 minutes to allow the sauce to thicken and prevent burning your mouth.
How To Store Leftovers?
First, let the leftover pie cool to room temperature. Then, cover it tightly with plastic wrap or place it in an airtight container. Store in the fridge for up to 3 days.
