Best Labor Day Peach & Bourbon Slab Pie: Easy Summer Dessert

For the longest time, I just accepted that feeding a crowd a fruit dessert meant either standing over a hot stove for hours or serving something that turned into a soggy mess before everyone got a slice. You know the drill—you spend all that time crimping a perfect double crust, only to have the first person cut into it and watch the juices flood the plate. It was the one thing that always stressed me out about hosting a Labor Day cookout. I wanted something that felt like a real, honest-to-goodness pie but could actually handle being carried from the kitchen to a picnic table without a meltdown. I tried making two regular pies, but that meant double the work and double the cleanup. I tried a galette, which was pretty but too rustic for the occasion. Nothing quite hit that sweet spot between impressive and practical.

Then I started thinking about slab pies. The concept made so much sense—more surface area for fruit, less worrying about a towering filling that wants to bubble over, and a crust-to-filling ratio that actually lets you taste both. But I needed something special for Labor Day, something that felt like the end of summer deserved. That’s when the bourbon came in. A little warmth, a little smoke, a little something that says “I’m not ready for fall just yet.” And the peaches? Well, they had to be the star. This Best Labor Day Peach & Bourbon Slab Pie came together after a few test runs (and one memorable incident involving a leaky pan and a smoking oven), and it’s been my go-to for late-summer gatherings ever since. It’s the dessert that finally made me stop worrying about the logistics and start actually enjoying the party.

Why You’ll Love This Recipe

Let me tell you why this slab pie has become the most-requested dessert at every summer get-together I host. It solves all the problems that come with feeding a crowd, and it does it with style.

• Feeds a Crowd Without the Fuss: This isn’t a dainty little 9-inch pie. This slab pie bakes up on a half-sheet pan, giving you enough slices to feed 12 to 16 people easily. No more making two pies or worrying about running out.
• No More Soggy Bottoms: The higher crust-to-filling ratio means every slice holds its shape beautifully. Plus, we’re using a few tricks—like pre-cooking the filling slightly and using a baking stone—to ensure that bottom crust stays crisp and golden.
• That Bourbon-Peach Combo: The bourbon doesn’t just add a boozy kick. It actually enhances the natural sweetness of the peaches and adds a subtle warmth that makes this taste like a grown-up treat. It’s the kind of flavor that makes people ask, “What’s in this?”
• Make-Ahead Friendly: You can prep the filling and the dough a day ahead. On the day of your party, just assemble and bake. Less stress, more time with your guests.
• Perfect for Labor Day: This is the dessert that says goodbye to summer in style. It’s bright and fruity but has that little something extra that feels celebratory. Pair it with a scoop of vanilla ice cream, and you’ve got a winner.

I’ve tested this recipe with a few different peach varieties, and honestly, it works with all of them. The key is using ripe but still firm peaches—you want them to hold their shape during baking, not turn into complete mush. And if you’re feeling extra fancy, a splash of good-quality bourbon makes all the difference.

What Ingredients You Will Need

This recipe relies on simple, high-quality ingredients that come together to create something truly special. Here’s what you’ll need to gather.

For the Pie Dough

• 3 cups all-purpose flour (I prefer King Arthur for its consistent protein content)
• 1 teaspoon salt
• 1 tablespoon sugar (just a touch to help with browning)
• 1 cup cold unsalted butter, cut into small cubes (keep it cold—this is non-negotiable for flaky crust)
• 1/2 cup ice water, plus more if needed
• 1 tablespoon apple cider vinegar (this helps tenderize the gluten and keeps the crust flaky)

For the Peach-Bourbon Filling

• 6 cups sliced fresh peaches, about 6-8 medium peaches (peeled if you prefer, though I like the texture with the skin on)
• 1/2 cup granulated sugar
• 1/4 cup light brown sugar, packed
• 3 tablespoons bourbon (use a good one—you’ll taste it)
• 2 tablespoons fresh lemon juice
• 1 teaspoon vanilla extract
• 1/4 cup cornstarch (this thickens the juices so you don’t get a runny pie)
• 1/2 teaspoon cinnamon
• 1/4 teaspoon nutmeg
• Pinch of salt

For Assembly & Topping

• 1 egg, beaten with 1 tablespoon water (for egg wash)
• 2 tablespoons coarse sugar, like turbinado or demerara (for that sparkly crunch)

I recommend using organic peaches when they’re in season—they just have more flavor. And for the bourbon, something like Bulleit or Maker’s Mark works beautifully. You don’t need the expensive stuff, but skip anything labeled “cooking bourbon.” It’s not worth it.

Equipment Needed

You don’t need a ton of fancy equipment for this recipe, but a few key tools will make your life much easier.

• Half-sheet pan (13×18 inches) with at least 1-inch sides. This is the standard size for slab pies. Don’t use a cookie sheet without sides—you’ll have juice everywhere.
• Rolling pin (I prefer a French rolling pin without handles, but any will do)
• Parchment paper (for easy lifting and cleanup)
• Large mixing bowls
• Pastry blender or food processor (for cutting butter into flour)
• Sharp knife or bench scraper
• Pastry brush (for egg wash)
• Cooling rack

If you don’t have a half-sheet pan, you can use a 9×13-inch baking dish, but you’ll need to adjust the baking time and the amount of dough. The slab pie is really designed for that larger surface area. I found my favorite half-sheet pan at a restaurant supply store for under $15—it’s thick, doesn’t warp, and has lasted for years. Worth every penny.

Preparation Method

Alright, let’s get to the fun part. Here’s how to put this Best Labor Day Peach & Bourbon Slab Pie together.

1. Make the Dough: In a large bowl, whisk together the flour, salt, and sugar. Add the cold butter cubes and toss to coat. Using a pastry blender or your fingertips, cut the butter into the flour until you have pea-sized pieces mixed with some larger flakes. Don’t overwork it—you want visible butter. In a small bowl, combine the ice water and apple cider vinegar. Drizzle over the flour mixture and stir with a fork until the dough just comes together. If it seems dry, add more ice water a tablespoon at a time. Divide the dough in half, flatten each into a disk, wrap in plastic, and refrigerate for at least 1 hour. (You can do this up to 2 days ahead.)
2. Prepare the Filling: In a large bowl, combine the sliced peaches, granulated sugar, brown sugar, bourbon, lemon juice, vanilla, cornstarch, cinnamon, nutmeg, and salt. Toss gently to coat. Let the mixture sit for about 15 minutes while you roll out the dough. This helps the peaches release some of their juices and allows the cornstarch to start working.
3. Preheat and Prep: Position a rack in the lower third of your oven and preheat to 400°F (200°C). Line your half-sheet pan with parchment paper, leaving some overhang on the long sides—this will help you lift the pie out later.
4. Roll Out the Bottom Crust: On a lightly floured surface, roll one disk of dough into a rectangle about 16×21 inches. It should be about 1/8-inch thick. Carefully transfer it to your prepared pan, letting the excess dough hang over the edges. Don’t stretch the dough—just gently press it into the corners and up the sides.
5. Add the Filling: Using a slotted spoon, transfer the peach mixture to the dough-lined pan, spreading it evenly. You want to leave most of the liquid behind in the bowl—too much juice will make your crust soggy. Reserve that liquid for something else, like drizzling over ice cream.
6. Roll Out the Top Crust: Roll the second disk of dough into the same size rectangle. Carefully place it over the filling. Trim the overhang to about 1/2 inch, then fold the edges under and crimp them with a fork or your fingers. Cut several slits in the top crust to allow steam to escape.
7. Egg Wash and Sugar: Brush the top crust with the beaten egg wash. Sprinkle generously with the coarse sugar. This gives you that beautiful golden, crunchy top.
8. Bake: Place the pan on the lower rack and bake for 20 minutes. Then, reduce the oven temperature to 375°F (190°C) and bake for another 30-35 minutes, until the crust is deep golden brown and the filling is bubbling through the slits. If the edges are browning too quickly, tent them with foil.
9. Cool: Let the pie cool on a wire rack for at least 2 hours before slicing. This is crucial—the filling needs time to set. If you cut into it too soon, you’ll have a runny mess.

Cooking Tips & Techniques

I’ve made this pie more times than I can count, and I’ve learned a few things along the way. Here are my best tips to ensure your slab pie turns out perfect every time.

Keep Everything Cold: This is the number one rule of pie crust. Cold butter, cold water, and a chilled dough. If your kitchen is warm, pop the dough back in the fridge for 10 minutes between rolling steps. Warm butter melts into the flour instead of creating steam pockets, and that’s what makes a crust tough instead of flaky.

Don’t Skip the Pre-Cook: I know it’s tempting to just toss everything in the pan and bake, but letting the peaches sit with the sugar and cornstarch for those 15 minutes makes a huge difference. It draws out some of the liquid and lets the cornstarch start its thickening magic. If you want to go a step further, you can cook the filling on the stovetop for 5 minutes before assembling—this ensures a perfectly thick, jammy filling.

Use a Baking Stone: If you have a pizza stone or baking steel, preheat it on the lower rack of your oven and place the sheet pan directly on it. This gives the bottom crust an extra blast of heat, helping it crisp up beautifully. I started doing this after one too many soggy-bottomed pies, and it’s a game-changer.

Watch the Edges: Slab pies have a lot of exposed crust edges, and they can brown quickly. If you notice them getting dark around the 25-minute mark, cover them with strips of foil or a silicone pie shield. You want a deep golden brown, not burnt.

Let It Cool Completely: I know you’ll want to dig in while it’s still warm, but trust me on this one. The filling needs at least 2 hours to set. If you cut into it while it’s hot, the juices will run everywhere and your beautiful slices will collapse. I learned this the hard way when I served a warm pie to guests and ended up with more of a peach soup situation. Patience pays off.

Variations & Adaptations

This recipe is wonderfully adaptable. Here are a few ways to make it your own.

Gluten-Free Version: Substitute the all-purpose flour with a good gluten-free blend that includes xanthan gum. I’ve had great results with Cup4Cup. The dough will be a bit more delicate, so handle it gently and roll it between two sheets of parchment paper.

Vegan Option: Use cold vegan butter (like Miyoko’s) in the crust and substitute the egg wash with a mixture of 1 tablespoon maple syrup and 1 tablespoon non-dairy milk. The crust won’t be quite as flaky, but it’s still delicious.

Nectarine Variation: Swap the peaches for nectarines—no need to peel them. The flavor is slightly more tart, which pairs beautifully with the sweet bourbon sauce. I made this version last August when peaches weren’t looking great at the market, and it was a hit.

Add Some Spice: For a warmer flavor profile, add a pinch of cardamom or ginger to the filling. I sometimes do this when I’m making the pie for a fall gathering that’s happening a little too early for pumpkin season. It gives the pie a cozy, almost chai-like warmth.

Bourbon-Free: If you’re serving kids or prefer no alcohol, simply replace the bourbon with an equal amount of apple cider or orange juice. You’ll lose that smoky note, but the pie will still be fantastic. I’ve made this version for family brunches, and nobody missed the bourbon.

If you’re looking for another crowd-pleasing dessert that’s perfect for parties, you might also enjoy these caramel apple snickerdoodle blondies. They’re just as easy to serve a crowd with.

Serving & Storage Suggestions

This slab pie is best served at room temperature, about 2-3 hours after it comes out of the oven. The filling will be perfectly set, and the crust will still have a slight crunch.

Presentation: Slice the pie into squares or rectangles—about 12 to 16 pieces, depending on how generous you want to be. A scoop of vanilla bean ice cream or a dollop of lightly sweetened whipped cream is the classic pairing. For a real treat, drizzle a little of that reserved peach-bourbon syrup over the top.

Storage: Cover the pie loosely with foil or plastic wrap and store at room temperature for up to 2 days. After that, transfer it to the refrigerator for up to 4 more days. The crust will soften slightly in the fridge, but the flavor will still be great.

Reheating: To reheat individual slices, pop them in a 350°F (175°C) oven for about 10 minutes. You can also microwave a slice for 20-30 seconds, but the crust won’t be as crisp. For the whole pie, reheat it in a 325°F (160°C) oven for 15-20 minutes.

Freezing: You can freeze the baked pie for up to 3 months. Let it cool completely, then wrap it tightly in plastic wrap and foil. Thaw overnight in the refrigerator and reheat as directed above. I’ve also frozen the unbaked assembled pie (without the egg wash) and baked it straight from frozen—just add about 15 minutes to the baking time.

This dessert pairs wonderfully with a hearty main dish. Try serving it after this maple bourbon pork chops with caramelized apples for a full Labor Day feast.

Nutritional Information & Benefits

While this is definitely a treat, there are some nutritional bright spots. Peaches are a good source of vitamins A and C, which support immune health and skin health. They also contain antioxidants like chlorogenic acid, which may help reduce inflammation. The bourbon, in moderation, has been linked to some heart health benefits, though I wouldn’t recommend drinking it for that reason alone!

If you’re watching your sugar intake, you can reduce the sugar in the filling to 1/2 cup total without sacrificing too much flavor—the natural sweetness of ripe peaches will carry the dessert. For a lower-fat option, you can substitute half the butter in the crust with cold vegetable shortening.

Frequently Asked Questions

Can I use frozen peaches for this recipe?

Yes, you can! Thaw the peaches first and drain off any excess liquid. You may need to add an extra tablespoon of cornstarch to compensate for the extra moisture. The texture won’t be quite as firm as with fresh peaches, but the flavor will still be delicious.

Do I have to peel the peaches?

Not at all. I actually prefer leaving the skin on most of the time—it adds a bit of texture and a pretty pink hue to the filling. If the skins are particularly thick or fuzzy, you can peel them by scoring an X on the bottom of each peach, blanching them in boiling water for 30 seconds, then plunging them into an ice bath. The skins will slip right off.

Can I make this pie ahead of time?

Absolutely. You can prepare the dough and the filling up to 2 days in advance and keep them refrigerated. On the day of baking, just assemble and bake. You can also bake the pie a day ahead, let it cool completely, and store it covered at room temperature. Reheat individual slices if desired.

What’s the best bourbon to use for this recipe?

I recommend a mid-range bourbon that you’d enjoy drinking. Something like Bulleit, Maker’s Mark, or Woodford Reserve works beautifully. Avoid anything labeled “cooking bourbon” or “bourbon flavoring”—they’re not worth the savings. The bourbon flavor is subtle but present, so use something you like.

My pie crust always turns out tough. What am I doing wrong?

The most common culprit is overworking the dough. When you mix the dough, stop as soon as it comes together. Overmixing develops the gluten, which leads to a tough crust. Also, make sure your butter and water are very cold. If your kitchen is warm, chill the dough for an extra 30 minutes before rolling. Finally, don’t skip the apple cider vinegar—it helps tenderize the gluten and keeps the crust flaky.
