Step 1

Preheat the oven to 400°F (200°C).

Step 2

Roll out the puff pastry just enough to fit the bottom of a 10-inch oven-safe skillet. Press it gently into the base and slightly up the sides. Refrigerate while you prepare the filling.

Step 3

In a small bowl, mix together the cinnamon, brown sugar, and cornstarch.

Step 4

Sprinkle half of the cinnamon-sugar mixture evenly on the bottom of the puff pastry.

Step 5

Arrange the peach slices over the spiced base in overlapping circles or rows.

Step 6

Sprinkle the remaining cinnamon mixture evenly over the peaches.

Step 7

Fold the edges of the puff pastry slightly over the filling to create a rustic border.

Step 8

Brush the crust with egg wash and sprinkle with coarse sugar.

Step 9

Drizzle the melted butter over the peach filling.

Step 10

Bake in the oven for 30-35 minutes, or until the crust is golden and the peaches are bubbling.

Step 11

Let cool for 10–15 minutes before slicing. Serve warm with ice cream or whipped cream.
