01 - Preheat the oven to 375°F. Arrange the unbaked pie crust in a 9-inch pie dish and crimp the edges as desired.
02 - In a large bowl, toss the sliced peaches with lemon juice, 1/2 cup sugar, and flour until evenly coated. Spread the peaches evenly in the prepared pie crust.
03 - In a separate bowl, whisk together eggs, milk, cream, 1/3 cup sugar, vanilla extract, nutmeg, and salt until smooth.
04 - Pour the custard mixture evenly over the peaches. Bake for 45–55 minutes, or until the custard is set and the top is lightly golden. If the crust begins to brown too quickly, cover the edges with foil.
05 - Let the pie cool completely on a wire rack. Chill in the refrigerator for at least 2 hours before serving for best slicing.
