Prep and preheat
- Preheat the oven to 375F and grease a 9x13 baking dish, so the crust can start setting immediately. Keep the dish ready for layering.
- Toss sliced peaches with granulated sugar, cinnamon, nutmeg, lemon juice, and cornstarch until combined, forming a thick, coated peach mixture. Make sure cornstarch is evenly distributed.
Layer the triple crust
- Press the first pie crust into the bottom of the dish and bake for 10 minutes until just set, preventing sogginess. The crust should look set but not deeply browned.
- Spoon half the peach filling over the first crust and dot with half the butter for rich, syrupy pockets. Spread gently so the layer is even.
- Press the second crust over the peaches, sealing in the filling as much as possible. Tuck edges as needed to help the structure hold.
- Top the second crust with the remaining peach filling and dot with the remaining butter for the second syrup layer. Level the peaches so they bake uniformly.
- Lay the third crust on top, then brush with the beaten egg and sprinkle with coarse sugar for a golden, crackly finish. Use an even coat so it caramelizes throughout.
Bake and rest
- Cut several vents in the top crust to let steam escape and keep filling from overflowing the dish. Aim for small slits distributed across the surface.
- Bake for 45-55 minutes at 375F until deeply golden and bubbling, with caramelized peach syrup pooling at the cracks. Look for vigorous bubbling around the vents.
- Let the cobbler rest 15 minutes before serving so the syrup thickens and slices lift cleanly. Serve warm for the most tender layers.
Notes
Pro tip: for clean slices with visible layers, use chilled rolled pie crusts and slice the baked cobbler after the 15-minute rest—this helps the peach syrup set without stopping the bubbling effect. Store covered in the refrigerator for up to 4 days; rewarm in a 350F oven for 10-15 minutes. Freezing is yes: freeze slices in airtight containers up to 2 months and thaw overnight in the fridge. For a lighter option, use unsalted butter reduced-fat sticks if you want slightly less richness while keeping the same layering method.
