Pioneer Woman Peach Slab Pie

I get a lot of questions about feeding a crowd a proper homemade dessert without standing over a hot stove for hours. The Pioneer Woman Peach Slab Pie is my go-to answer. It delivers a buttery, flaky crust wrapped around a juicy, cinnamon-kissed peach filling, all baked on a single sheet pan for easy slicing and serving.

This recipe takes about 135 minutes from start to finish, and I would call it intermediate. The crust requires patience, and getting the top crust to seal properly takes a little care. It is ideal for summer barbecues, potlucks, or any gathering where you need dessert for a dozen people without pulling out a dozen pie plates.

A Quick Glimpse at Pioneer Woman Peach Slab Pie

This is a classic American dessert built on a sheet pan instead of a round pie dish. Fresh peaches get tossed with warm spices and a touch of lemon, then sandwiched between two layers of homemade butter pastry. The result is a dessert with a crisp, golden crust and a soft, jammy center that holds its shape when cut. It tastes like peak summer, and the slab format means everyone gets a generous square with plenty of crust in every bite.

Why This Recipe is Worth Trying

• Feeds a crowd — This single pie easily serves 12 to 16 people depending on how you slice it, making it perfect for parties and family reunions.
• Great crust-to-fruit ratio — Every square delivers a satisfying balance of flaky pastry and sweet peach filling, so nobody gets stuck with a soggy middle slice.
• Uses fresh summer produce — Ripe peaches shine here, and the natural juices create a rich, thick filling without any artificial thickeners beyond cornstarch.
• Make-ahead friendly — You can prepare the dough a day in advance and assemble the pie a few hours before baking, which saves time on busy days.

Essential Ingredients for This Recipe

Gathering everything on the list is straightforward, and most items are pantry staples already sitting in your kitchen. Here is what you need and why each ingredient earns its place.

For the Pie Dough

• 2 1/2 cups all-purpose flour, plus more for dusting — All-purpose flour gives the crust structure while keeping it tender. Measure by spooning into the cup and leveling off for accuracy.
• 1 tablespoon granulated sugar — A small amount of sugar adds a subtle sweetness to the pastry and helps with browning in the oven.
• 1 teaspoon fine sea salt — Salt balances the sweetness of the filling and keeps the crust from tasting flat.
• 1 cup (2 sticks) cold unsalted butter, cut into 1/2-inch cubes — Cold butter is essential for flaky layers. Unsalted butter lets you control the salt level, and keeping it chilled prevents it from melting into the flour.
• 1/2 cup ice water, plus more as needed — Ice water brings the dough together without warming the butter. Have extra on hand in case the dough feels dry.

For the Peach Filling

• 1/2 cup granulated sugar — This sweetens the filling and helps draw out the natural juices from the peaches.
• 1/4 cup packed light brown sugar — Brown sugar adds a deeper, molasses-like sweetness that pairs beautifully with cinnamon and nutmeg.
• 3 tablespoons cornstarch — Cornstarch thickens the peach juices during baking so the filling sets instead of running everywhere.
• 1 teaspoon ground cinnamon — Cinnamon is the classic warm spice that makes peach desserts taste complete.
• 1/4 teaspoon ground nutmeg — A pinch of nutmeg adds warmth and depth without overpowering the fruit.
• 1/8 teaspoon fine sea salt — A tiny bit of salt enhances all the sweet and fruity flavors in the filling.
• 6 cups fresh peaches, peeled and sliced (about 6-8 medium peaches) — Ripe but firm peaches work best. They hold their shape during baking while softening enough to become jammy.
• 1 tablespoon fresh lemon juice — Lemon juice brightens the peaches and prevents them from browning after slicing.
• 1 teaspoon vanilla extract — Vanilla rounds out the flavors and adds a subtle warmth to the filling.

For Assembly and Topping

• 2 tablespoons cold unsalted butter, cut into small pieces — Small butter pieces dotted over the filling melt into the peaches, adding richness and helping the filling thicken.
• 1 large egg, beaten with 1 tablespoon water (for egg wash) — An egg wash gives the top crust that shiny, golden finish that makes pies look bakery-worthy.
• 2 tablespoons coarse sugar (such as turbinado or demerara), for sprinkling — Coarse sugar adds a pleasant crunch on top and a sweet, sparkly finish.

Useful Equipment

Having the right tools makes this recipe smoother, though you can work around most of them in a pinch.

• 18×13-inch rimmed baking sheet — This is the exact pan size for a slab pie. A rimmed sheet catches any filling that bubbles over during baking.
• Pastry blender — This tool cuts cold butter into flour quickly and evenly. Your fingertips work too, but a pastry blender keeps the butter from warming up too fast.
• Rolling pin — A standard rolling pin is essential for rolling the dough into those large rectangles. A French pin without handles gives you better control.
• Parchment paper — Lining the pan with parchment prevents sticking and lets you lift the entire pie out for easy slicing.
• Pastry brush — You need this for applying the egg wash evenly across the top crust without brushing off the coarse sugar.

Directions to Make Pioneer Woman Peach Slab Pie

The method breaks down into manageable stages, and paying attention to a few key details makes all the difference. Here is the process, step by step.

• Start the dough — Whisk the flour, 1 tablespoon sugar, and 1 teaspoon salt together in a large bowl. Cut in the cold butter cubes with a pastry blender or your fingertips until the mixture looks like coarse meal with some pea-sized butter pieces remaining. Those little chunks of butter create the flaky layers.
• Add the ice water — Sprinkle the ice water over the flour mixture one tablespoon at a time, tossing with a fork until the dough just starts coming together. It should look shaggy but hold together when you squeeze it. If it is too dry, add more ice water a teaspoon at a time. Overmixing makes a tough crust.
• Chill the dough — Turn the dough onto a lightly floured surface, gather it into a ball, and divide it into two equal discs. Flatten each into a 1-inch-thick round, wrap in plastic wrap, and refrigerate for at least 1 hour or up to 2 days. Chilling relaxes the gluten and keeps the butter firm.
• Preheat and prep the pan — Position a rack in the lower third of the oven and preheat to 375°F / 190°C. Line an 18×13-inch rimmed baking sheet with parchment paper, leaving overhang on the long sides for easy lifting.
• Roll and place the bottom crust — On a lightly floured surface, roll one disc into a rectangle about 22×15 inches and about 1/8-inch thick. Drape it over the baking sheet, pressing gently into the bottom and up the sides. Trim excess dough, leaving a 1/2-inch overhang, and refrigerate while you make the filling.
• Mix the dry filling ingredients — In a small bowl, whisk together the 1/2 cup granulated sugar, brown sugar, cornstarch, cinnamon, nutmeg, and 1/8 teaspoon salt. Set aside.
• Combine the peaches and sugar — In a large bowl, toss the sliced peaches with lemon juice and vanilla extract. Sprinkle the sugar mixture over the top and toss gently to coat. Let it sit for 10 minutes so the peaches release their juices and the cornstarch starts dissolving.
• Fill the crust — Pour the peach filling into the chilled crust and spread it evenly. Dot the top with the small pieces of cold butter.
• Add the top crust — Roll the second disc into a rectangle about 20×14 inches and 1/8-inch thick. Place it over the filling, trim the edges, and fold the overhang under. Crimp the edges to seal. Cut 6 to 8 slits in the top for steam, brush with egg wash, and sprinkle with coarse sugar.
• Bake until golden — Bake for 45 to 55 minutes until the crust is golden brown and the filling bubbles through the slits. If the edges brown too quickly, cover them loosely with aluminum foil.
• Cool before slicing — Remove the pie and let it cool on a wire rack for at least 30 minutes. This lets the filling set so it does not run out when you cut it.
• Lift and slice — Use the parchment overhang to lift the whole pie onto a cutting board. Slice into squares and serve warm or at room temperature, ideally with vanilla ice cream.

What I Got Wrong (And How I Fixed It)

The first few times I made this, a handful of things tripped me up. Here is what went sideways and the fixes that worked.

• Warm butter ruined my first crust — I cut the butter while it was still slightly soft, and the dough turned greasy instead of flaky. Keep the butter in the fridge until the last minute and work quickly.
• The filling ran everywhere — I skipped the 10-minute rest for the peaches, so the cornstarch never dissolved properly. Let the peaches sit with the sugar mixture before baking.
• Soggy bottom crust — The bottom of my pie came out pale and doughy the first time. Baking on the lower oven rack helped the bottom cook thoroughly before the top over-browned.
• Edges burned while the middle was fine — The thin edges of the crust cook faster than the center. Covering the edges with foil during the last part of baking saved the crust.
• Cutting too early — I sliced into the pie after 10 minutes and the filling poured out everywhere. Waiting the full 30 minutes lets the filling set into a sliceable texture.
• Dough stuck to my work surface — Not dusting the surface enough made the dough tear when rolling. Use a generous amount of flour and re-dust as needed.

Healthier Ways to Make Pioneer Woman Peach Slab Pie

If you want to lighten this dessert up a little, a few simple swaps cut back on sugar and fat without ruining the flavor.

• Reduce the sugar — Cut the granulated sugar in the filling down to 1/4 cup if your peaches are very ripe and sweet. You will lose some sweetness but gain more fruit flavor.
• Swap whole wheat pastry flour — Replace half of the all-purpose flour with whole wheat pastry flour for extra fiber. The texture stays tender, just slightly nuttier.
• Use a butter substitute — Coconut oil or a plant-based butter works in the crust at a 1:1 ratio. Chill it well before cutting into the flour.
• Skip the coarse sugar topping — The coarse sugar adds crunch but also extra calories. Brush the egg wash on alone, or use a sprinkle of cinnamon instead.
• Add more fruit — Mix in 1 cup of fresh blueberries or raspberries alongside the peaches. You get more volume and antioxidants without much extra sugar.

Ingredient Substitutions for Pioneer Woman Peach Slab Pie

Fresh peaches are not always available, and sometimes you are halfway through the recipe before realizing you are missing something. These swaps save the day.

• Fresh peaches → frozen sliced peaches — Frozen peaches work well; thaw and drain them first, then pat dry. Add 1 extra tablespoon of cornstarch since frozen fruit releases more juice.
• Unsalted butter → salted butter — If you only have salted butter on hand, reduce the salt in the dough to 1/2 teaspoon and skip the salt in the filling.
• All-purpose flour → gluten-free baking flour — A 1:1 gluten-free baking blend works in the crust, but expect a slightly crumblier texture. Add 1 teaspoon of xanthan gum if your blend does not include it.
• Lemon juice → apple cider vinegar — In a pinch, 1 tablespoon of apple cider vinegar adds the same acidity to brighten the peaches and prevent browning.
• Vanilla extract → almond extract — Almond extract gives the filling a nutty, fragrant twist. Use 1/2 teaspoon instead of 1 teaspoon since it is stronger.
• Granulated sugar → honey or maple syrup — Liquid sweeteners work but reduce the sugar to 1/3 cup and decrease the ice water by 2 tablespoons to balance the extra moisture.

Unexpected Ways to Enjoy This Pioneer Woman Peach Slab Pie

Beyond a simple slice with ice cream, this pie works in some surprising ways.

• Breakfast treat — Warm a square and top it with Greek yogurt and a drizzle of honey. It feels indulgent but works surprisingly well with morning coffee.
• Ice cream sandwich base — Slice the pie into thin strips and sandwich a scoop of vanilla ice cream between two pieces. Freeze for 30 minutes for a messy but amazing dessert.
• Pie milkshake — Blend one slice of cooled pie with a scoop of vanilla ice cream and a splash of milk. You get a thick, peachy shake that tastes like a summer float.
• Dessert charcuterie board — Cut the pie into small squares and arrange them on a board with fresh berries, whipped cream, and a stack of shortbread cookies.
• Fruit crisp topping — Crumble leftover pie crust over the top of a bowl of warm peach compote for an instant cobbler-like dessert.
• Frozen yogurt bites — Cut small squares, top each with a dollop of frozen yogurt, and freeze. These make a fun, portable summer snack.

Best Tips for Pioneer Woman Peach Slab Pie Success

These are the small details that separate a good slab pie from a fantastic one.

• Keep everything cold — The butter, the water, and even your hands should stay cold. Warm ingredients melt the butter into the flour, which destroys the flaky layers.
• Peel the peaches properly — Score an X on the bottom of each peach, blanch in boiling water for 30 seconds, and shock in ice water. The skins slip right off without wasting fruit.
• Do not overwork the dough — Mix until the dough just comes together. Overworking develops gluten, which makes the crust tough instead of tender and flaky.
• Let the filling rest — Those 10 minutes of resting are not optional. They give the cornstarch time to absorb the peach juices, which prevents a runny filling.
• Use the lower oven rack — Baking on the lower third of the oven concentrates heat on the bottom crust, so it cooks through without the top burning.
• Cut slits before baking — Steam needs an escape route. Those 6 to 8 slits prevent the top crust from puffing up or cracking unevenly.
• Cool completely before slicing — The filling continues to set as the pie cools. Slicing too early creates a mess, and the squares fall apart.

Tasty Twists on Pioneer Woman Peach Slab Pie

Once you master the classic version, try one of these flavor variations to keep things interesting.

• Peach-Berry Slab Pie — Replace 1 cup of the peaches with fresh blueberries or raspberries. The berries add a tart pop of color and flavor.
• Spiced Chai Peach Pie — Add 1/2 teaspoon of chai spice blend to the filling along with the cinnamon and nutmeg. The cardamom and ginger notes pair beautifully with peaches.
• Almond-Crusted Peach Pie — Sprinkle 1/2 cup of sliced almonds over the filling before adding the top crust. The nuts toast during baking and add crunch.
• Bourbon Peach Slab Pie — Stir 2 tablespoons of bourbon into the peach filling for a warm, smoky depth. Reduce the vanilla extract to 1/2 teaspoon.
• Ginger-Peach Slab Pie — Add 1 tablespoon of finely grated fresh ginger to the filling. The bright, spicy kick cuts through the sweetness beautifully.
• Oat Streusel Peach Pie — Skip the top crust entirely and sprinkle a mixture of oats, brown sugar, butter, and flour over the filling for a crumble-style finish.

Best Ways to Store Your Pioneer Woman Peach Slab Pie

Leftovers keep well when stored properly, so you can enjoy this dessert for days.

• Refrigerator — Cover the pie tightly with plastic wrap or foil and store in the refrigerator for up to 3 days. The cold keeps the filling firm and prevents spoilage.
• Freezer (whole pie) — Wrap the baked, cooled pie tightly in aluminum foil and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Freezer (individual slices) — Wrap each square separately in plastic wrap, then place in a freezer-safe bag. This makes it easy to grab a single serving.
• Countertop (same day) — If you plan to eat it within a few hours, cover lightly with foil and leave at room temperature. Do not leave it out longer than 4 hours.
• Vacuum-sealed pack — For long-term freezing, vacuum-sealing removes air and prevents freezer burn. Store for up to 6 months.

Ways to Warm It Up Again

Reheating brings back that fresh-from-the-oven flavor and flaky texture.

• Oven — Preheat to 350°F / 177°C and warm the pie or individual squares for 10-15 minutes. This method restores the crispy crust best.
• Toaster oven — For individual slices, use a toaster oven at 350°F until warmed through. It is faster than the full oven and perfect for a single serving.
• Microwave — Heat individual squares on a microwave-safe plate for 30-45 seconds. The filling gets hot quickly, but the crust softens rather than stays crisp.
• Air fryer — Set the air fryer to 320°F and heat slices for 3-5 minutes. This revives the crunch while warming the filling evenly.

Ingredients

Scale 1x2x3x

• 2 1/2 cups all-purpose flour, plus more for dusting
• 1 tablespoon granulated sugar
• 1 teaspoon fine sea salt
• 1 cup (2 sticks) cold unsalted butter, cut into 1/2-inch cubes
• 1/2 cup ice water, plus more as needed
• 1/2 cup granulated sugar
• 1/4 cup packed light brown sugar
• 3 tablespoons cornstarch
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg
• 1/8 teaspoon fine sea salt
• 6 cups fresh peaches, peeled and sliced (about 6–8 medium peaches)
• 1 tablespoon fresh lemon juice
• 1 teaspoon vanilla extract
• 2 tablespoons cold unsalted butter, cut into small pieces
• 1 large egg, beaten with 1 tablespoon water (for egg wash)
• 2 tablespoons coarse sugar (such as turbinado or demerara), for sprinkling

Instructions

1. Prepare the pie dough: In a large bowl, whisk together the flour, 1 tablespoon sugar, and 1 teaspoon salt. Add the cold butter cubes and, using a pastry blender or your fingertips, cut the butter into the flour until the mixture resembles coarse meal with some pea-sized butter pieces remaining. This ensures a flaky texture.
2. Sprinkle the ice water over the flour mixture, 1 tablespoon at a time, tossing with a fork until the dough just begins to come together. Do not overmix; the dough should be shaggy but hold together when squeezed. If needed, add more ice water, 1 teaspoon at a time.
3. Turn the dough out onto a lightly floured surface, gather it into a ball, then divide into two equal discs. Flatten each disc into a 1-inch-thick round, wrap in plastic wrap, and refrigerate for at least 1 hour or up to 2 days.
4. Position a rack in the lower third of the oven and preheat to 375°F / 190°C. Line an 18×13-inch rimmed baking sheet with parchment paper, leaving overhang on the long sides for easy lifting.
5. On a lightly floured surface, roll out one disc of dough into a rectangle about 22×15 inches and about 1/8-inch thick. Drape the dough over the prepared baking sheet, gently pressing it into the bottom and up the sides. Trim excess dough, leaving a 1/2-inch overhang. Refrigerate while preparing the filling.
6. Make the filling: In a small bowl, whisk together the 1/2 cup granulated sugar, brown sugar, cornstarch, cinnamon, nutmeg, and 1/8 teaspoon salt. Set aside.
7. In a large bowl, combine the sliced peaches, lemon juice, and vanilla extract. Sprinkle the sugar mixture over the peaches and toss gently to coat. Let stand for 10 minutes, allowing the peaches to release their juices and the cornstarch to begin dissolving—this helps thicken the filling during baking.
8. Pour the peach filling into the chilled crust, spreading it evenly. Dot the top with the small pieces of cold butter.
9. Roll out the second disc of dough into a rectangle about 20×14 inches and 1/8-inch thick. Place it over the filling. Trim the edges and fold the overhang under, then crimp the edges to seal. Use a sharp knife to cut 6 to 8 slits in the top crust to allow steam to escape, then brush the entire top with the egg wash using a pastry brush. Sprinkle evenly with coarse sugar.
10. Bake for 45 to 55 minutes, or until the crust is golden brown and the filling is bubbling through the slits. If the edges start to brown too quickly, cover them loosely with aluminum foil.
11. Remove the pie from the oven and let it cool on a wire rack for at least 30 minutes before slicing. This allows the filling to set so it doesn’t run out when cut.
12. Using the parchment overhang, lift the pie out of the baking sheet and transfer to a cutting board. Slice into squares and serve warm or at room temperature, with vanilla ice cream if desired.

Notes

Storage: Keep leftover pie covered in the refrigerator for up to 3 days. Freezing: The baked slab pie can be wrapped tightly in foil and frozen for up to 3 months. To reheat, thaw overnight in the refrigerator, then warm in a 350°F / 177°C oven for 10-15 minutes until heated through. For best results, reheat individual squares in a toaster oven at 350°F until warm.
