Preheat oven to 375°F (190°C). Prepare a quarter sheet pan (approximately 9×13 inches).
Cut a small X in the bottom of each peach. Blanch in boiling water for about 45 seconds, then transfer to ice water to cool. Peel skins off.
Slice peaches 1/2 inch thick. Combine slices in a bowl with granulated sugar, ground cinnamon, fresh lemon juice, vanilla extract, cornstarch, nutmeg, and salt. Mix well.
Roll out one sheet of puff pastry to fit the bottom and sides of the prepared pan.
Use a slotted spoon to spread the peach mixture over the pastry base, leaving excess juice behind in the bowl.
Roll out the second puff pastry sheet. Cut into 10 strips about 1 inch wide.
Create a lattice top: Lay half the pastry strips evenly across the pan. Fold back every other strip. Place one strip perpendicular over the unfolded strips. Unfold the folded strips back over the perpendicular strip. Repeat the folding and placing process with the remaining strips to complete the lattice. Trim excess pastry and pinch the edges to seal.
Whisk together the egg and 1 tablespoon water to make an egg wash. Brush this wash over the pastry lattice. Sprinkle generously with coarse sugar.
Bake for 30-40 minutes, or until the pastry is deep golden brown and the filling is bubbly. If the crust browns too quickly, cover loosely with aluminum foil.
Cool in the pan on a wire rack for 15-20 minutes before slicing into bars. Serve warm with vanilla ice cream.

FAQs: Frequently Asked Questions About Peach Slab Pie Bars

Can I use frozen peaches for Peach Slab Pie Bars?

Yes, you can use frozen peaches, but it’s best to thaw them completely and drain any excess liquid before baking. Using frozen peaches may release more moisture, so adding a little extra cornstarch or flour to the filling helps prevent sogginess. Fresh peaches are preferred for a firmer texture and better flavor.

Is it necessary to peel peaches for making Peach Slab Pie Bars?

Peeling peaches is recommended to avoid chewy skin in the bars, especially since slab pies have a large exposed fruit surface. If your peaches have thin skin and you don’t mind a bit of texture, you can leave the skin on, but peeling provides a smoother bite.

How can I prevent my Peach Slab Pie Bars from getting soggy?

To avoid soggy bars, drain excess juice from the peach filling before placing it on the crust. Using a slotted spoon helps remove liquid. Also, bake the bars until the crust is golden brown and cooked through. Adding a thickening agent like cornstarch or tapioca starch to the peach filling can absorb extra moisture.

Can Peach Slab Pie Bars be prepared ahead of time?

Yes, you can prepare the peach filling a day before baking and store it in the refrigerator. Assemble and bake the bars on the day you plan to serve them for the best texture. Fully baked bars can be kept at room temperature for up to 24 hours or refrigerated for 3 to 4 days.

What can I use if I don’t have a quarter sheet pan for Peach Slab Pie Bars?

A 9×13-inch baking pan works well as an alternative to a quarter sheet pan. Just make sure the pan has similar depth to allow even baking of the bars. Adjust baking time slightly as needed, checking for a golden crust and set filling.
