Preheat the oven: Preheat the oven to 425°F.: As the oven warms you will notice a steady, dry heat building inside, which is important for an even bake and crisp crust. Set your oven precisely to 425°F , and allow it to fully reach temperature, because a cold oven can lead to a soggy bottom. A properly preheated oven helps the crust set quickly, locking in flakiness while encouraging the filling to start bubbling. A common mistake is not waiting for full preheat, which causes uneven browning and longer cook times.
Craft your crust: After removing your homemade or store bought crust from the fridge you’ll want to allow it to rest for up to 10 minutes, this will make it easier to roll out. Once it’s softened you’ll want to flour your rolling pin, to prevent the dough from sticking, and get to work. Each disc will need to be 1/8 of an inch thick. Place the dough gently onto the pie plate before crimping the edges and removing any excess dough.: When you let the dough rest briefly after refrigeration it relaxes and becomes much easier to roll, producing a smoother, more even crust surface. Flour your rolling pin lightly so the dough does not drag or tear, and roll each disc to about 1/8 of an inch thickness for a balanced crunch and tenderness. As you place the crust on the pie plate, press gently to avoid stretching, this preserves flakiness during baking. If you stretch the dough while fitting it, it will shrink back in the oven, leaving gaps between crust and filling.
Blind bake the bottom: Place a piece of parchment paper over the pie shell and fill it with pie weights. If you don't have pie weights, you can use dry beans. Place the pie shell into the oven and blind bake it for 15 minutes. Read more about blind baking here. Once done, remove the pie weights and the parchment paper from the pie shell.: Lining the shell with parchment and pie weights creates gentle, uniform pressure so the bottom holds its shape and avoids bubbling. As the pie shell heats, you should see the edges take on a faintly golden hue after about 15 minutes , a cue that the crust is setting. Remove the weights carefully; the shell will be sturdy but still flexible enough to handle the filling. A pitfall here is skipping the weights, which can lead to a collapsed or uneven bottom.
Prepare the filling: In a large bowl place the sliced peaches and sprinkle with the lemon juice. Mix gently with a wooden spoon. In another bowl mix the flour, sugar, cinnamon, nutmeg and salt. Add the flour mixture to the peaches and toss well.: Tossing the sliced peaches with lemon juice immediately after peeling keeps the fruit bright and fragrant while it sits. When you whisk together the flour , sugar , cinnamon , nutmeg , and salt , you are building a balance of sweetness, spice, and thickening power that will coat each slice. Mixing these dry ingredients thoroughly ensures even distribution so each bite has consistent flavor. A common error is undercoating the fruit, which can result in a filling that becomes too watery.
Assemble your pie: Add the filling to your bottom crust, and dollop with butter pieces all over the filling. Roll out your top crust in the same way described above and drape it over your pie. Crimp and seal your edges before slicing vents in the top crust with a knife or if you really want to impress, cut into long strips and weave a lattice crust. From there you will brush with the beaten egg, making sure to seal the edges.: As you mound the filling into the blind baked shell, you will hear a soft rustle as fruit nests into the crust, and the air will fill with a fresh peach aroma. Dotting the surface with pieces of butter adds pockets of richness that melt into the fruit. When you roll and place the top crust, crimp the edges firmly to seal, then cut slits or weave a lattice so steam can vent and the filling can bubble without overflowing. Brushing the top with the beaten egg will give a glossy, deeply browned finish. A misstep here is not sealing the edges well, which can let juices leak out and burn on the oven floor.
Bake the pie: Preheat your oven first to 425°F. Add the pie to the oven, on the bottom rack and bake for 10 minutes. Reduce the heat to 350°F and bake for another 45 minutes to an hour or until the crust is golden brown and the filling is bubbling.: Start the bake on the bottom rack at 425°F so the crust gets an initial lift and color, then reduce to 350°F for a prolonged finish that allows the filling to thicken and the crust to brown evenly. You will notice a lively bubbling near the vents and a golden brown edge when the pie is nearly done, visual cues that the sugars are caramelizing and the filling has set. Bake for 10 minutes at the higher temp, then 45 minutes to an hour at the lower temp, checking for a deeply golden top and bubbling filling. Avoid opening the oven too often, which drops heat and extends bake time.
Cool and serve: Cool before serving, though I prefer this pie warm with a scoop of ice cream.: As the pie rests, the filling will thicken and the juices will settle, turning from runny to spoonable. You will still smell warm peaches and butter, and the crust softens slightly at the edges while maintaining a satisfying crisp. Cooling also prevents a slice from collapsing when cut, so allow adequate time before serving; I personally enjoy it slightly warm with a scoop of ice cream. A frequent mistake is cutting too soon, which leads to a loose, liquid center.
