Pecan Slab Pie: Easy Southern Dessert for a Crowd

Table of Contents

This pecan slab pie delivers the classic Southern filling you love, scaled up to feed a crowd from a single sheet pan.

Pecan slab pie is the kind of dessert that earns its place at the center of the table without demanding hours of complicated work from you. Instead of coaxing a finicky round pie into neat wedges that crumble at the edges, you press a buttery pastry into a rimmed sheet pan, pour over a glossy, caramel-scented filling packed with toasted pecans, and slide the whole thing into the oven. The result slices into clean, generous rectangles that are easy to plate, easy to transport, and far easier to serve than a traditional pie when you are feeding more than six people.

What makes this version particularly reliable is the ratio of filling to crust. A standard nine-inch pie can feel overwhelmed by filling, leaving each bite dense and intensely sweet. When you spread that same spirit of a pecan pie across a thirteen-by-eighteen-inch rimmed baking sheet, the filling thins out just enough to set beautifully without becoming rubbery, and every piece gets an honest proportion of flaky pastry underneath. The crust itself is a simple press-in style, so you skip the rolling pin entirely. It is forgiving, honest baking at its best.

Serves

16 servings

Ingredients

1 package (16 oz) refrigerated pie crusts (2 crusts)
1 cup light corn syrup
1 cup packed dark brown sugar
4 large eggs, lightly beaten
1/4 cup unsalted butter, melted and cooled
2 teaspoons pure vanilla extract
1/2 teaspoon fine sea salt
1/4 teaspoon ground cinnamon
2 1/2 cups roughly chopped pecans
1/2 cup whole pecan halves (for topping)

Instructions

1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan and line with parchment paper, leaving overhang on two sides for easy lifting.
2. Unroll both refrigerated pie crusts and press them side by side into the bottom of the prepared pan, overlapping slightly in the center. Press seams together and fold any excess crust up the sides to form a low edge. Prick the base all over with a fork.
3. Par-bake the crust for 8 minutes until just set but not browned. Remove from oven and let cool for 5 minutes.
4. Whisk together corn syrup, brown sugar, beaten eggs, melted butter, vanilla extract, salt, and cinnamon in a large bowl until fully combined and smooth.
5. Fold in the roughly chopped pecans, then pour the filling evenly over the par-baked crust.
6. Scatter the whole pecan halves across the top of the filling in an even layer.
7. Bake for 30–35 minutes until the filling is set around the edges with a very slight jiggle in the very center. Do not overbake.
8. Cool completely in the pan on a wire rack — at least 1 hour — before lifting out using parchment overhang and slicing into bars.

Tips & Notes

– For cleaner slices, refrigerate the fully cooled slab for 30 minutes before cutting with a sharp knife.
– Dark brown sugar deepens the molasses flavor — use light brown sugar for a milder, more classic taste.
– Store sliced bars in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week.
– To freeze, wrap individual slices in plastic wrap and place in a zip-top freezer bag for up to 2 months. Thaw at room temperature.

The press-in pastry is the first reason this recipe holds up under pressure. Because you are pressing rather than rolling, there is no risk of overworking the dough. You simply combine the ingredients, press the mixture evenly across the pan, and let the oven do the rest. The crust bakes up with a satisfying snap at the edges and a tender, almost shortbread-like crumb at the base, which supports the filling without going soggy.

The filling leans on a combination of eggs, brown sugar, light corn syrup, a touch of unsalted butter, and a generous pour of alcohol-free vanilla extract to deliver that deep, toasty flavor you expect from a classic pecan pie. Spreading it across a sheet pan means the filling layer is thinner than in a standard pie, which translates to a faster, more even set. You get clean edges, a glossy top, and that satisfying chew in every bite without worrying about an undercooked center.

What You Will Need for the Crust and Filling

For the press-in crust, you need all-purpose flour, a pinch of salt, a little powdered sugar to keep things tender, cold unsalted butter cut into small cubes, and a couple of tablespoons of ice water to bring it together. The powdered sugar dissolves more readily than granulated, which keeps the texture smooth rather than grainy.

For the filling, gather four large eggs, one and a half cups of packed light brown sugar, one cup of light corn syrup, six tablespoons of melted unsalted butter, one teaspoon of alcohol-free vanilla extract, half a teaspoon of fine salt, and three cups of pecan halves. Toasting the pecans before adding them to the filling makes a noticeable difference. Spread them on a dry sheet pan and let them sit in a 350-degree oven for about seven minutes, until they smell nutty and look a shade darker. That brief step intensifies their flavor through the entire bake. You can also use roughly chopped pecans if you prefer a more uniform slice, though halves look striking on top.

How to Make Pecan Slab Pie From Start to Finish

Start by preheating your oven to 350 degrees Fahrenheit and lightly greasing a rimmed half-sheet pan, roughly thirteen by eighteen inches. Cut a sheet of parchment paper to fit the base and up the short sides, leaving a couple of inches of overhang on those ends. This makes lifting the finished slab much easier once it has cooled.

To make the crust, whisk together two and a half cups of all-purpose flour, two tablespoons of powdered sugar, and half a teaspoon of salt in a large bowl. Add the cold cubed butter and work it in with your fingertips or a pastry cutter until the mixture looks like coarse, damp sand with a few pea-sized pieces remaining. Drizzle in the ice water one tablespoon at a time, tossing with a fork until the dough just begins to clump. Turn it out into the prepared pan and press it evenly across the bottom and about half an inch up each side. Use the flat bottom of a measuring cup to smooth it out. Prick the surface all over with a fork, then slide it into the oven for fifteen minutes, until the edges are just beginning to turn golden. Remove it and let it rest while you prepare the filling.

In a large bowl, whisk together the eggs and brown sugar until the mixture is smooth and the sugar has mostly dissolved. Add the corn syrup, melted butter, vanilla, and salt, whisking until everything is fully combined. Fold in the toasted pecans. Pour the filling over the warm crust, spreading it gently so the pecans distribute evenly across the surface. Return the pan to the oven and bake for twenty-five to thirty minutes. The filling is done when the edges are set and puffed slightly, and the center has just a gentle wobble when you nudge the pan. It will firm up considerably as it cools, so do not be tempted to overbake it chasing a completely still center. Pull it out when that wobble is subtle rather than sloshy. Let the slab cool completely in the pan on a wire rack, at least two hours, before slicing into rectangles.

Tips for the Best Results Every Time

Keep your butter genuinely cold when making the crust. If your kitchen is warm, cube the butter and pop it back into the freezer for ten minutes before using it.
Do not skip the parchment overhang on the short ends. Once the slab is fully cooled, you can lift the whole thing onto a cutting board and slice it cleanly without the pan getting in your way.
Use a serrated knife with a gentle sawing motion to cut through the pecan layer without dragging the filling. Wiping the blade between cuts keeps the edges tidy.
If you notice the top browning faster than you would like in the last ten minutes, tent the pan loosely with foil. The crust edges are particularly prone to darkening before the center sets.
Room temperature eggs incorporate into the filling more smoothly than cold eggs straight from the refrigerator. Set them out about thirty minutes before you begin.
Brown sugar variety matters: light brown sugar gives a milder caramel note, while dark brown sugar pushes toward a more molasses-forward flavor. Both work, so choose based on your preference.

Ways to Change Up This Slab Pie

Once you are comfortable with the base recipe, there are several directions you can take it depending on the season, your audience, or what you happen to have on hand.

Chocolate layer: Scatter half a cup of dark chocolate chips across the warm crust before pouring the filling over the top. The chips melt into a thin layer that makes each bite richer without overwhelming the pecan flavor.
Spiced filling: Add half a teaspoon of ground cinnamon and a pinch of ground ginger to the filling for a warm, autumnal edge. This variation works especially well for a Thanksgiving spread.
Mixed nut version: Replace one cup of the pecans with a mix of roughly chopped walnuts and cashews. The combination gives you more textural contrast and stretches your pecans further when you are feeding a large group.
Brown butter filling: Instead of using plain melted butter, brown the butter in a small saucepan until it smells nutty and the milk solids turn amber. Cool it briefly before whisking it into the filling. The result is a noticeably deeper, more complex flavor.
Coconut addition: Stir in half a cup of unsweetened shredded coconut with the pecans. The coconut toasts gently during baking and adds a subtle chewiness alongside the nuts.
Mini slab pies: Press the dough into two standard nine-by-thirteen pans instead of one half-sheet pan for a slightly thicker filling. This option is useful if a half-sheet pan is not part of your setup yet.

How to Store and Reheat Leftovers

Once the slab has cooled completely, store leftover slices in an airtight container at room temperature for up to two days. Beyond that, transfer them to the refrigerator, where they will keep well for up to five days. The filling firms up considerably when chilled, which is actually pleasant if you enjoy a denser, more fudgy texture. Let refrigerated slices sit at room temperature for twenty to thirty minutes before serving for the best consistency.

If you prefer a warm slice, place individual pieces on a parchment-lined baking sheet and warm them in a 300-degree oven for about eight to ten minutes. Avoid using a microwave if possible, as it can make the crust soft rather than keeping it snappy. The slab also freezes well. Wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag. They will keep for up to two months. Thaw overnight in the refrigerator and bring to room temperature before serving.

Frequently Asked Questions

Can you make the crust ahead of time? Yes. Press the crust into the prepared pan, cover it with plastic wrap, and refrigerate it for up to a day before blind-baking. This actually helps the crust hold its shape along the edges.
What if you do not have corn syrup? You can substitute an equal amount of pure maple syrup for a slightly different but equally good result. The filling may be a touch less glossy but just as delicious.
Is it normal for the filling to bubble during baking? Yes. The sugar and eggs will puff and bubble gently around the edges as the pie bakes. This is expected and a sign that the heat is reaching the filling properly.
How do you know the slab is fully cooled? The filling should feel firm and barely tacky when you press the center lightly with a fingertip. If it still gives significantly, give it another thirty minutes before slicing.
