Method
Prepare and layer the pie
- Preheat the oven to 425°F, then press the unbaked 9-inch deep-dish pie crust into a 9-inch deep-dish pie dish.
- Arrange the sliced ripe peaches in the unbaked crust so they sit evenly across the bottom.
Make the custard and assemble
- Whisk together the eggs, granulated sugar, sour cream, all-purpose flour, vanilla extract, and cinnamon until smooth, with no dry flour streaks.
- Pour the custard over the peaches so it nearly covers the fruit.
- Sprinkle the optional crumble topping over the surface if using.
Bake, cool, and chill
- Bake at 425°F for 15 minutes until the edges start to set and turn lightly golden, then reduce to 350°F.
- Bake at 350°F for 30-35 minutes until the custard is set in the center and the crust is golden.
- Cool the pie for 30 minutes at room temperature so the custard firms up slightly.
- Refrigerate the pie for 2 hours to fully set before slicing.
- Serve chilled with whipped cream, and finish each plate with a clear view of peaches peeking through the custard.
Notes
For the smoothest custard, whisk just until the mixture turns glossy and lump-free—overmixing can add air that may puff and then settle. Refrigerate leftovers in an airtight container up to 4 days; freezing is not recommended because custard can weep after thawing. If you want a lower-sugar version, reduce granulated sugar by about 1/4 cup and expect a slightly softer set.
