The Essential Ingredients for the Best Pumpkin Pie
This recipe uses simple, classic ingredients to create a truly spectacular, from-scratch result.
- The Tender Shortbread Crust: This is a rich, tender, and almost cookie-like crust (pâte sucrée) that is the perfect sturdy base for our custard filling.
- Room Temperature Butter: It is crucial that your unsalted butter is properly softened to room temperature. This is the secret to the “creaming method,” which creates a smooth, emulsified dough and a wonderfully tender, “melt-in-your-mouth” final crust.
- Confectioners’ Sugar: Using powdered sugar instead of granulated sugar is a professional trick that creates a very fine, smooth, and tender texture in the finished crust.
- The Silky-Smooth Pumpkin Filling:
- Pure Pumpkin Purée: It is absolutely essential to use 100% pure pumpkin purée, not pumpkin pie filling (which is pre-sweetened and spiced). This gives you complete control over the flavor and sweetness of your pie.
- Heavy Cream & Eggs: These are the key to a rich, smooth, and perfectly set custard filling. Using room temperature eggs will help them incorporate more smoothly into the batter.
- Warm Spices: A classic, cozy, and perfect blend of ground cinnamon and freshly grated nutmeg provides the signature “pumpkin spice” flavor.
Step-by-Step to the Perfect Pumpkin Slab Pie
This recipe is a rewarding baking project. Follow these detailed steps for a perfect, show-stopping result.
Part 1: Create the Foil Pan and Make the Shortbread Dough
Step 1: First, position an oven rack in the bottom third of the oven and preheat it to 350°F (175°C).
Step 2: Tear off two 24-inch pieces of 18-inch-wide heavy-duty aluminum foil. Line a 10×15-inch rimmed baking sheet with the foil, crisscrossing the pieces to cover the entire pan and leaving a generous overhang on all sides. Fold over each overhang so that it stands upright, forming a sturdy foil wall that is about 3 inches high. Crimp the corners together to seal them. Lightly coat the bottom and the foil sides with cooking spray.
Step 3: For the dough, in a large bowl with an electric mixer, beat the 1 pound of room temperature butter, the 1 1/4 cups of confectioners’ sugar, and the 1 teaspoon of salt on medium-high speed for about 1 minute, until smooth.
Step 4: Add half of the 5 cups of all-purpose flour and beat to incorporate. Add the remaining flour and beat on low speed until the dough just starts to come together in large, soft clumps.
Step 5: Set aside about one-third of this dough in a separate bowl for making the decorative edge later.
Part 2: Form and Par-Bake the Crust
Step 1: Press half of the remaining (larger portion of) dough into the bottom of your prepared foil-lined baking sheet until it is completely covered in a layer that is about 1/4-inch thick.
Step 2: Press the remaining dough into and about 1 inch up the sides of the foil wall to create the crust’s edge.
Step 3: Bake the crust for 20 to 25 minutes, until it is a light golden color. Let the par-baked crust cool completely on a wire rack.
Part 3: Prepare the Decorative Edge and the Silky Filling
Step 1: While the crust is cooling, take the one-third of the dough that you reserved. Knead it a few times to bring it together. Place it between two pieces of flour-dusted parchment paper and roll it out to about 1/8-inch thickness.
Step 2: Use a 1-inch round cookie cutter to cut out about 50 small rounds of dough. In a small bowl, beat the 1 large egg with a little bit of water to create an egg wash, and then brush the tops of each round with the egg wash. Refrigerate the rounds until you are ready to use them.
Step 3: For the filling, in a large bowl, gently whisk together the two cans of pumpkin purée, the 2 1/2 cups of heavy cream, the 1 1/2 cups of granulated sugar, the 4 large eggs, the 2 teaspoons of ground cinnamon, the 1 teaspoon of grated nutmeg, the 1 teaspoon of pure vanilla extract, and the 1/2 teaspoon of salt until everything is well blended.
Pro Tip: Be careful not to over-mix the filling. Over-whisking incorporates too much air, which can cause the pie to puff up and then crack as it cools.
Step 4: Assemble and Bake the Slab Pie
Step 1: Pour the prepared pumpkin filling into the cooled, par-baked pie shell.
Step 2: Carefully press the chilled, 1-inch dough rounds in a single, overlapping line all around the edges of the crust to create a beautiful, decorative border.
Step 3: Bake for 50 minutes to 1 hour. The pie is perfectly done when the filling is set around the edges, but the very center is still slightly wiggly when you gently shake the pan.
Step 4 (The Most Important Step!): Let the pie cool completely on a wire rack. Then, wrap the entire pan and refrigerate it overnight. This crucial, uninterrupted chilling period is absolutely essential for the custard filling to fully set up, which is the secret to a perfect, clean slice.
When ready to serve, cut the pie into squares and serve with a generous dollop of freshly whipped cream.

- Creating a sturdy wall with heavy-duty foil inside the baking sheet is a key technique for this slab pie.
- The crust is a press-in shortbread style, which is easier to work with than a traditional rolled pie dough for a large pan.
- Chilling the pie overnight is a crucial step to ensure the custard filling sets properly for clean slices.

Frequently Asked Questions (FAQs)
Q1: What is a “slab pie” and why is it so great for the holidays?
A “slab pie” is simply a pie that is baked in a large, rectangular, rimmed baking sheet instead of a traditional round pie pan. It is fantastic for the holidays because a single slab pie can serve twice as many people as a standard 9-inch pie, and it is much, much easier to cut into neat, uniform squares for easy serving to a crowd.
Q2: What is the secret to a pumpkin pie that doesn’t crack on top?
There are two main secrets to a beautiful, crack-free pumpkin pie. First, be very careful not to over-mix your filling, especially after you have added the eggs. Over-mixing whips too much air into the custard, which causes it to puff up and then crack as it cools. Second, do not over-bake your pie. Pull it from the oven when the center still has a slight jiggle.
Q3: Why is the overnight chill in the refrigerator so important?
This is the most crucial step for any custard pie! The egg- and cream-based filling is very delicate when it is warm. The long, uninterrupted chilling period is absolutely essential for the custard to fully set and firm up. If you try to cut into a warm or even a room-temperature pumpkin pie, you will have a delicious, but soupy, mess instead of a clean, beautiful slice.
Q4: Can I use a store-bought pie crust for this recipe to save time?
Because of the large, unique, rectangular format of this slab pie, a standard, store-bought refrigerated pie crust will be too small. However, you could substitute the homemade shortbread crust with a simple, press-in graham cracker or gingersnap cookie crust.
Q5: What kind of pumpkin purée should I use?
It is very important that you use 100% pure pumpkin purée, not pumpkin pie filling. Pumpkin pie filling is a pre-made product that already contains sugar and spices, which will throw off the balance of this recipe and make your pie overly sweet and improperly spiced.
