01 - Preheat the oven to 375°F.
02 - Arrange the unbaked pie crust in a 9-inch pie dish. Crimp the edges as desired for a finished appearance.
03 - 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.
04 - In a separate bowl, whisk together eggs, milk, cream, 1/3 cup sugar, vanilla extract, nutmeg, and salt until smooth and well combined.
05 - 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.
06 - Let the pie cool completely on a wire rack. Chill in the refrigerator for at least 2 hours before serving for best slicing results.
