Prep and pre-bake
- Preheat oven to 375F and grease a 9x13 baking dish. Set it aside so the dish is ready to build the layered cobbler.
- Toss sliced peaches with granulated sugar, cinnamon, nutmeg, lemon juice, and cornstarch until combined. The mixture should look evenly coated with no dry cornstarch pockets.
- Press the first pie crust into the bottom of the dish and bake for 10 minutes until just set. Look for light set edges without full browning.
Build the triple crust layers
- Spoon half the peach filling over the first crust and dot with half the unsalted butter. Distribute to reach the corners so each slice gets syrupy filling.
- Press the second pie crust over the peaches, then top with the remaining peach filling and butter. Aim for an even layer so the third crust sits flat.
- Lay the third pie crust on top, brush with egg wash, and sprinkle with coarse sugar. You should see a glossy top surface where the egg wash hits.
- Cut several vents in the top crust and bake for 45-55 minutes until deeply golden and bubbling. Watch for peach syrup bubbling through the vents and golden caramel color.
Rest and serve
- Let the triple crust peach cobbler rest 15 minutes before serving. The layers will thicken slightly so the slice holds and syrup settles at the cracks.
Notes
For clean slices with distinct layers, use room-temperature pie crusts and let the cobbler cool for the full 15 minutes (no rushing). Store covered in the refrigerator up to 4 days; rewarm individual portions in the microwave at 50% power until just warm. Freezing is not recommended because the triple-crust layers can soften after thawing. If you want a lighter option, swap half the granulated sugar for light brown sugar or a sugar substitute that measures 1:1 for baking, keeping the cornstarch the same for proper thickening.
