Notes
This recipe is designed for a quick dessert using store-bought puff pastry. For best results, use ripe but firm peaches. Leftovers can be stored at room temperature for up to 2 days.
Why This Dish Belongs in Your Busy Schedule
Forget layering and fussing. Throw sliced peaches onto thawed puff pastry. Sprinkle sugar + cornstarch straight from the bag. Dot with butter. Egg wash? Yes, because it makes the top gold. That’s it. One sheet pan. Zero pots. No stand mixer. No sifting. The cornstarch thickens the juice without a stove. The butter melts into a glaze. You don’t even need a pastry brush—use your fingers. This is grit: do the bare minimum that still tastes like a peach pie. Pair it with Crowd-Pleasing Sheet Pan Walking Tacos for a full sheet-pan dinner that doesn’t wreck your kitchen.
The Perfect Occasion for This Recipe
This is not for a fancy dinner party. This is for a Tuesday when you just got home from work, the kids are hungry, and you promised dessert. A 15-minute prep means you can throw it in the oven while you eat dinner. By the time plates are cleared, the slab pie is cool enough to cut. You feed eight people with zero effort. No lattice work. No crimping. This is the “I’m exhausted but I still got this” move. If you have canned peaches, use them. Drain them well. No one will know. The egg wash is optional. The turbinado sugar? Skip it if you’re out. The pie survives.
Frequently Asked Questions
Can I use frozen peaches?
Yes. Thaw and drain well. Toss with extra cornstarch. Frozen peaches release more liquid. Add one more tablespoon cornstarch.
Do I have to peel the peaches?
Nope. The skin softens during baking. If you hate fuzzy skin, peel. Otherwise leave it. I don’t peel. Time is too short.
What if I don’t have puff pastry?
Use pie crust. Two store-bought rounds. Press them into a sheet pan. Works fine. Bake 5 minutes less.
Can I make this ahead?
Bake it. Cool. Cover. It sits at room temp for 6 hours. Reheat at 350°F for 5 minutes. Don’t refrigerate or it gets soggy.
Conclusion
The pie is out. You ate. The dishes? One sheet pan. Rinse. Done. Go sit down. Scroll your phone. Don’t overthink this. You fed people real dessert in under half an hour. That’s a win. If you want another no-effort sweet, try Creamy Blueberry Swirl Cheesecake with Graham Cracker Crust. But for now, exit the kitchen. You earned it.
