Pecan Slab Pie Recipe

This Pecan Slab Pie Recipe brings all the buttery, gooey goodness of classic pecan pie to a sheet pan, where it’s easy to slice and share with a crowd. A tender homemade crust holds a rich brown sugar and corn syrup filling with plenty of pecans, making each square a lovely mix of crisp pastry, toasted nuts, and soft, sweet center.

Ingredients You'll Need

The ingredient list is simple, but each part earns its place: cold butter helps make a flaky crust, while the syrup, sugars, and eggs set into that signature glossy pecan filling. For the best texture, measure the pecans before chopping and keep the crust ingredients cool.

• All-purpose flour: Use 3 cups, or 360 grams, to form the sturdy, tender pastry; keep a little extra nearby for rolling.
• Granulated sugar: One tablespoon adds a touch of sweetness to the crust, and 1 cup sweetens the filling.
• Salt: Use ½ teaspoon in the crust and 1 teaspoon in the filling to balance the sweetness.
• Salted butter: You’ll need ¾ cup, cold and cubed, for the crust and ½ cup, melted, for the filling.
• Large eggs: One egg helps bring the pastry together, while 2 eggs give the filling its rich, sliceable set.
• Ice water: Start with 1 tablespoon and add another if needed to help the dough come together without warming it too much.
• Distilled white vinegar: One teaspoon adds a little tenderness to the pastry.
• Pecan halves: Measure 2 cups before chopping so you have a generous layer of pecans throughout the pie.
• Light corn syrup: Use 1½ cups to give the filling its classic smooth, gooey texture.
• Light brown sugar: Three packed tablespoons lend a gentle molasses note to the filling.
• Vanilla extract: Two teaspoons bring warmth and round out the buttery, nutty flavors.

How to Make Pecan Slab Pie Recipe

Step 1: Prepare the crust for your Pecan Slab Pie Recipe

In a large bowl, whisk together the flour, 1 tablespoon of granulated sugar, and ½ teaspoon salt. Add the cold, cubed butter and cut it into the flour with a pastry cutter or two knives until you have coarse crumbs with pea-sized pieces of butter still visible. Those little pieces help create a flaky crust as the pastry bakes.

Step 2: Bring the dough together and chill

In a small bowl, combine the egg, 1 tablespoon of ice water, and the vinegar, then pour the mixture into the flour. Stir gently with a fork until a shaggy dough forms, adding the second tablespoon of ice water only if the mixture still seems dry. Gently knead just until the dough holds together, shape it into a flattened rectangle, wrap it tightly, and refrigerate for at least 1 hour, until firm.

Step 3: Heat the oven and prepare the pan

Set the oven to 375°F and lightly grease a 15 x 10-inch rimmed baking sheet, also called a jelly roll pan. A rimmed pan is important here because it holds the filling securely while the pie bakes. Once the dough is chilled, generously flour your work surface and rolling pin.

Step 4: Roll and fit the pastry

Roll the dough into an even rectangle about 17 x 12 inches, lifting and turning it as needed to prevent sticking. Carefully transfer it to the prepared pan, then gently press it into the corners and up the sides. Tuck or crimp the edges neatly along the rim, patching any small tears with a scrap of dough if needed.

Step 5: Add the pecans and make the filling

Scatter the chopped pecans evenly over the bottom of the unbaked crust. In a large bowl, whisk together the corn syrup, 1 cup granulated sugar, melted butter, brown sugar, vanilla, 1 teaspoon salt, and 2 eggs until the mixture looks smooth and fully combined. Pour the filling gently over the pecans; they’ll rise toward the top as the pie bakes.

Step 6: Bake until set

Bake for 35 to 40 minutes, checking toward the end of the baking time. The crust should be golden at the edges, and the filling should look set with just a subtle jiggle in the center when you gently shake the pan. If the pastry edges are browning faster than the center is setting, loosely cover the edges with foil.

Step 7: Cool before slicing

Transfer the pan to a wire rack and let the pie cool completely before cutting it into squares. The filling continues to firm up as it cools, so it’s worth giving it time; slicing while it’s still warm can leave you with softer, messier pieces.

How to Serve Pecan Slab Pie Recipe

Garnishes

Serve each square as it is, or add a small dollop of softly whipped cream for a light contrast to the sweet filling. A scoop of vanilla ice cream is another welcome option, especially if the pie is just slightly warm. For a simple finishing touch, sprinkle a few extra chopped pecans over the cream or add a tiny pinch of flaky salt to bring out the buttery, toasted flavors.

Side Dishes

This pie is a rich dessert, so it pairs beautifully with coffee, black tea, or a not-too-sweet cup of chai. If you’re serving it as part of a holiday meal, fresh fruit such as sliced pears or tart apples makes a refreshing addition alongside the dessert spread. Keep other sweets on the lighter side and let the pecan squares be the star.

Creative Ways to Present

For a gathering, cut the cooled pie into neat squares and arrange them on a platter with the pecan-studded tops facing up. Smaller squares work well on a dessert buffet, while larger pieces feel right at home on a plated dessert with ice cream. You can also tuck a few squares into individual cupcake liners to make them easier for guests to pick up.

Make Ahead and Storage

Storing Leftovers

Once the pie has cooled completely, cover the pan tightly or move the squares to an airtight container. Store leftovers in the refrigerator for up to 4 days. Chilling helps the filling stay firm and makes it easy to pack individual squares for a treat later in the week.

Freezing

For longer storage, let the pie cool completely, then cut it into squares and freeze them in a single layer until firm. Transfer the pieces to a freezer-safe container, placing parchment between layers to prevent sticking. Thaw individual squares overnight in the refrigerator or let them sit at room temperature until ready to serve.

Reheating

To enjoy a warm square, heat it in a 300°F oven for about 8 to 10 minutes, checking that it’s warmed through without becoming too soft. You can also microwave an individual piece in short bursts, though the crust will be softer. If your pie is frozen, thaw it first for the most even warming.

FAQs

Can I use store-bought pie crust?

Yes, if you’re short on time, you can use prepared pie dough. Make sure you have enough to cover the bottom and sides of a 15 x 10-inch rimmed pan, and join or roll the pieces together as needed. The homemade crust adds a lovely buttery texture, but prepared dough can make the recipe more convenient.

How do I know when the filling is done?

Look for golden crust edges and a center that has set around the outside but still moves with a slight jiggle when you gently shake the pan. It will continue to firm as it cools. Avoid waiting for the entire surface to feel completely rigid in the oven, since that can lead to an overbaked filling.

Why does the dough need to chill?

Chilling firms the butter and gives the dough time to relax, which makes it easier to roll and less likely to shrink in the oven. If the pastry softens while you’re working with it, place the pan in the refrigerator for a few minutes before adding the filling.

Can I make this pie a day ahead?

Absolutely. Bake it the day before you plan to serve it, let it cool fully, then cover and refrigerate it. The filling will be nicely set by serving time, and you can offer the squares chilled or warm them gently in the oven.

Can I use whole pecan halves instead of chopping them?

You can, though chopped pecans make the pie easier to cut into tidy squares and distribute the nuts more evenly in each serving. If you prefer the look of whole pecans, arrange them over the base before pouring in the filling, keeping the layer fairly even.

Final Thoughts

If you love classic pecan pie but want an easy way to serve a crowd, this Pecan Slab Pie Recipe is a lovely one to keep close. Make the crust, let the filling bake until just set, and give it time to cool before slicing; then enjoy those sweet, buttery squares with friends and family.
