Peach Slab Pie

Everything you love about fresh peach pie, baked in a sheet pan! One peach slab pie easily yields 18-24 slices, so it's perfect for sharing with friends. This post contains an affiliate link.

It's peach season! I order a 25-pound box of fresh peaches from The Peach Truck every year. They are so yummy and make the perfect snack. We eat most of them fresh and plain, but I ALWAYS make sure to use the last of the peaches to make pie.

Peach slab pie is absolutely delicious, and it's sturdy enough to pick up a slice with your hands, although I prefer eating it with a fork. Slab pie is easier to serve than a regular pie and stays fresh for up to 3 days, so it makes great leftovers. Slab pie is the ultimate comfort dessert.

I make my slab pies in a 10×15″ jelly roll pan. This is a great all-around size. It's smaller than the half-sheet baking pans that I typically use but easier to work with when rolling out the dough.  You can turn any pie recipe into a slab pie by doubling your favorite two-crust pie crust recipe and making about 1 ½ batches of pie filling. Make sure to follow my tips and tricks for achieving a perfectly baked crust (top and bottom)---very important!

WHAT MAKES THIS RECIPE A KEEPER

• Basic ingredients: My pie crust recipe is a keeper, a variation of my favorite pie crust recipe from Betty Crocker. It uses shortening, butter, and oil for the best texture and flavor. You can use canned pie filling if you'd like (you'll need 3 cans), but I like making peach pie filling from scratch. It's super simple and gives you the best flavor.
• The crust is forgiving: Not great at making pie crust? That's ok. Slab pie tastes delicious regardless, and because it's made with a combination of shortening, oil, and butter, it's a little easier to roll out than an all-butter pie crust. Do your best to roll it into a rectangular shape, but just know that once it's baked up, the golden top and bubbly filling will hide imperfections.
• Feeds a crowd: One jelly roll pan of slab pie yields 18-24 slices.
• Stays fresh for several days: Mine have been kept for at least 3 days, making this a great dessert to make the night before you need it.

🥧 TIPS FOR BAKING SLAB PIE CRUST

Fruit pies, if not baked properly, can end up with an underbaked bottom crust or one that goes soggy after a few hours---don't ask me how I know. This is because fruit fillings break down during baking and leak juice. Peach pies are notorious when it comes to leaking juice, but my pies always have a solid, flaky crust. No sogginess at all.

Having a properly thickened filling (using flour) and making sure your crust is baked properly is key. This is especially important with slab pie because it has a large surface area. Here are 5 tips for perfectly baked pie crust:

1. Use Crust Dust: I first learned about the miracle of CRUST DUST from King Arthur Flour. It's super easy to make, too! Crust dust is a 1:1 ratio of all-purpose flour and sugar. You simply mix the two ingredients together, then sprinkle it over the bottom crust in a THIN layer before adding the pie filling. As the pie bakes, the flour and sugar create a barrier, preventing the juices from soaking into the crust. It really works, too, and once baked, you won't even know it's there.
2. Bake In Bottom ⅓ of Oven: Baking the pie lower in the oven (I bake on the second to bottom rack position) helps the bottom crust to bake evenly.
3. Use a Baking Stone: I swear by baking my pies on top of a preheated baking stone (pizza stone). If you don't have one that's ok! The first two tips will still yield a delicious crust. The baking stone just helps center the heat evenly for the bottom crust.
4. Use a Metal Pan: metal pie pans work better than glass for a golden bottom crust.
5. Don't Worry About Overbaking Your Pie: yep, that's what I said. It's better to slightly overbake the crust vs. underbake. I bake my slab pies for 30 minutes, then loosely cover with foil for another 20-25 minutes. Covering the pie for the last half of the baking process will help the top not get too brown. And a tip for making fruit pies: if the filling isn't bubbling up and almost coming out of the pie, it's not done! 

🥣Ingredients

PIE CRUST

• All-purpose flour
• Salt
• Shortening: This is key in creating a tender and flaky crust.
• Butter: You can use salted butter or unsalted butter.
• Vegetable oil: This also aids in creating a tender and flaky crust.
• Milk or buttermilk: You can use buttermilk or a combination of milk and lemon juice. I don't always have buttermilk on hand, so I use the milk and lemon juice hack.

PEACH PIE FILLING

• Fresh peaches
• Sugar
• All purpose flour for thickening.
• A dash of cinnamon for spice.
• A splash of lemon juice to keep the peaches bright and balance out the sweetness.

CRUST DUST

• 2 Tbsp. all-purpose flour
• 2 Tbsp. sugar

EGG WASH

• egg and water

👩‍🍳 Directions

• Mix flour and salt in a large bowl. Cut in shortening using a pastry cutter. Cut in butter until the particles are the size of small peas.
• Combine milk and lemon juice together in a small bowl.
• Add oil and milk/lemon mixture to the flour mixture and stir until a soft dough forms. You may need to use your hands to form the mixture into a dough.

• Divide the dough into two equal portions. Flatten into a disc and wrap with plastic. Refrigerate while you make the pie filling (about 30 minutes).
• Peel and chop peaches into small pieces. Sprinkle sugar, flour, and cinnamon over chopped peaches and stir until coated.
• Preheat the oven to 400 degrees. If you have a pizza stone, place it on the oven rack to preheat.
• Roll pie crust on a lightly floured surface. Keep rolling until it is a 13x18" rustic-looking rectangle. It won't be exact, and that's ok.
• Place the rectangle into a 10x15" jelly roll pan, allowing the excess to hang over the edge of the pan.
• Sprinkle crust dust over the pie crust bottom.
• Pour the peach filling over the bottom crust.

• Roll the second crust out into a rustic-looking 13x18" rectangle.
• Place on top of the pie.
• Fold the edges of the top and bottom crust back and tuck into the pan.
• Use your fingers to pinch and crimp the edges of the pie (or use a fork to crimp).

• Cut slits into the top of the pie to allow steam to vent while baking.
• Brush the crust lightly with egg wash then sprinkle with sugar.

• Bake slab pie for 30 minutes.
• Cover/tent loosely with foil and bake for an additional 20-25 minutes.
• The top should be GOLDEN and the filling should be bubbling.
• Allow the pie to cool for at least 2 hours before slicing.
