This easy pecan slab pie combines a flaky, buttery crust with a rich, caramel-like filling and plenty of pecan halves. Sweetened naturally with maple syrup and brown sugar, it avoids corn syrup while delivering classic pecan pie flavor. Ideal for holidays, potlucks, and any gathering where you need a big, impressive dessert.
I tested this slab pie several times to balance texture and sweetness. A simple warmed syrup of brown sugar, water, and pure maple syrup gives the filling a clean, deep caramel note without relying on high-fructose corn syrup. A touch of ground cinnamon and a generous amount of butter round out the flavor for a filling that is luxuriously smooth and slightly chewy when set.
Because this is a slab pie baked in a rimmed baking sheet, it serves a crowd—about 20–24 squares—so it’s perfect for Thanksgiving or large family gatherings. The method is straightforward: press a large rectangle of refrigerated crust into the pan, layer pecans across the bottom, pour the glossy filling over them, and bake. Once cooled, the pie cuts into neat squares for easy serving.
Easy Pecan Slab Pie takes the best of traditional pecan pie—caramelized sweetness, toasted nuts, and buttery pastry—and scales it up. Using refrigerated pie crusts keeps prep time low while still delivering a flaky base that crisps along the edges during baking. The filling sets to a custardy texture that holds when sliced, while the pecans provide the essential crunch.

Ingredients for Easy Pecan Slab Pie
For the Simple Syrup
- 1 1/4 cups brown sugar
- 6 tablespoons water
- 1/4 cup pure maple syrup
- 1/4 teaspoon salt
For the Pie
- 3 (9-inch) refrigerated pie crusts
- 12 tablespoons (1 1/2 sticks) salted butter, softened
- 1 1/4 cups brown sugar
- 5 large eggs
- 2 teaspoons vanilla extract
- 1 1/4 cups simple syrup (from above)
- 1 1/2 tablespoons cornstarch
- 3/4 teaspoon ground cinnamon
- Pinch of salt
- 2 tablespoons bourbon (optional)
- 4 cups pecan halves
Step-by-Step Directions
1. Make the simple syrup
Combine the brown sugar, water, maple syrup, and salt in a small saucepan. Warm over low to medium-low heat, stirring until the sugar dissolves and the mixture is clear. Do not boil—just dissolve and remove from heat. Let cool slightly before using in the filling.
2. Prepare the crust
Preheat the oven to 350°F (175°C). Spray a 12×17-inch rimmed baking sheet with non-stick spray. Unroll the refrigerated crusts and stack them; gently roll into a roughly 15×20-inch rectangle to eliminate seams and ensure even coverage. Fit the dough into the prepared pan, pressing into the corners and up the sides. Trim excess and patch any gaps.
3. Add the pecans
Spread the pecan halves in an even layer across the bottom of the crust so every slice will have nuts in it.
4. Make the filling
In a stand mixer or with a hand mixer, cream the softened butter and brown sugar until smooth. Add the eggs one at a time, mixing after each. Stir in vanilla, the cooled simple syrup, cornstarch, cinnamon, salt, and bourbon if using. Mix until glossy and fully combined.
5. Assemble and bake
Pour the filling evenly over the layer of pecans and smooth the top. Bake 45–55 minutes until the edges are golden and the center is set but still has a slight jiggle. The filling will settle as it cools. Cool completely before cutting into squares for clean slices.
Tips for Perfect Pecan Slab Pie
- Use refrigerated crusts for convenience; brush with melted butter before baking for a richer finish.
- Remove from oven when the center still jiggles slightly—carryover heat will finish setting the filling.
- Toast pecans briefly for deeper flavor and crunch.
- Sprinkle flaky sea salt over the top after baking for a sweet-and-salty contrast.
- Bake a day ahead and store covered at room temperature or refrigerate for longer shelf life.
Serving Ideas
Serve warm or at room temperature with a scoop of vanilla ice cream, a drizzle of caramel sauce, or lightly sweetened whipped cream dusted with cinnamon. This pie also travels well and makes an excellent make-ahead dessert for holidays or potlucks.
How to Store and Freeze
- Store at room temperature, loosely covered, for up to 3 days.
- Refrigerate in an airtight container for up to 5 days.
- Freeze individual slices wrapped tightly for up to 2 months; thaw in the refrigerator or at room temperature before serving.
Variations
- Chocolate Pecan: Stir 1 cup mini chocolate chips into the filling for a chocolate finish.
- Maple Bourbon: Increase maple syrup and a touch more bourbon for a bolder maple-bourbon profile.
- Salted Caramel Bars: Drizzle warmed caramel over the baked pie before cutting for portable bars.
