As the crisp autumn air rolls in and pumpkin season takes center stage, there’s no dessert more comforting than a Creamy Spiced Pumpkin Slab Pie with a Buttery Crust. This recipe delivers all the flavors of a traditional pumpkin pie, but with the ease and shareable charm of a slab pie. Whether you’re hosting a festive gathering, a cozy family dinner, or preparing for Thanksgiving, this recipe ensures that everyone gets a perfectly creamy, spiced slice with a flaky, golden crust.
Why This Pumpkin Slab Pie Stands Out
Our pumpkin slab pie isn’t just another pumpkin dessert — it’s a masterpiece of flavor and texture. The rich pumpkin filling, infused with warm spices like cinnamon, ginger, nutmeg, and cloves, creates a luscious custard that perfectly complements the buttery, crisp crust. Unlike traditional pies, this slab version bakes evenly and serves beautifully in squares, making it ideal for entertaining large groups.
The blend of granulated and brown sugar adds depth and a hint of caramel sweetness, while evaporated milk brings a luxurious creaminess. The result? A dessert that’s indulgent, balanced, and irresistibly smooth.
Ingredients for the Perfect Pumpkin Slab Pie
To create this stunning dessert, gather these simple yet essential ingredients:
- 1 refrigerated pie crust (or homemade for a rustic touch)
- 1 can (15 oz) pumpkin puree – choose 100% pure pumpkin for authentic flavor
- 1 can (12 oz) evaporated milk – gives the filling its signature creaminess
- 3 large eggs – for structure and silky texture
- ¾ cup granulated sugar – for sweetness
- ½ cup brown sugar – for a deeper caramel undertone
- 1½ tsp ground cinnamon – the warm spice that defines pumpkin pie
- ½ tsp ground ginger – adds subtle heat and zest
- ¼ tsp ground nutmeg – brings nutty, aromatic warmth
- ¼ tsp ground cloves – for bold, earthy spice
- ½ tsp salt – balances all the flavors
- Whipped cream – for serving, light and fluffy
These ingredients come together to create a pie that is creamy, aromatic, and perfectly spiced, embodying the very essence of fall.
Step-by-Step Directions for a Flawless Pumpkin Slab Pie
1. Prepare the Baking Pan and Crust
Start by preheating your oven to 400°F (200°C). Lightly grease a 10×15-inch rimmed baking sheet or jelly roll pan to ensure easy release after baking. Roll out the pie crust to fit the pan, pressing gently into corners and trimming any excess dough. For an extra-flaky base, prick the crust lightly with a fork to prevent bubbling during baking.
2. Make the Creamy Pumpkin Filling
In a large mixing bowl, whisk together the pumpkin puree, evaporated milk, eggs, granulated sugar, brown sugar, and all spices until smooth and thoroughly combined. This step is key — a well-blended filling ensures that each bite has a uniform texture and consistent spiced flavor.
3. Bake to Golden Perfection
Pour the pumpkin filling evenly into the prepared crust. Bake for 15 minutes at 400°F, then reduce the temperature to 350°F (175°C) and continue baking for 25–30 minutes, or until the center is set but slightly jiggles when gently shaken. The reduction in temperature allows the custard to bake gently, preserving its creamy consistency.
4. Cool and Cut into Perfect Squares
Remove the slab pie from the oven and allow it to cool completely on a wire rack. Once cooled, slice into neat, generous squares using a sharp knife. Each piece reveals a velvety pumpkin layer on a crisp, buttery base — a perfect combination of textures.
5. Serve with Whipped Cream or a Sprinkle of Cinnamon
Top each slice with a dollop of freshly whipped cream or a light dusting of ground cinnamon. The cool cream balances the warmth of the spices, creating a beautiful contrast of flavors and textures.
Expert Tips for Pumpkin Slab Pie Success
To make your pie truly exceptional, keep these expert baking tips in mind:
- Use pure pumpkin puree, not pumpkin pie filling — this allows you to control the spice and sweetness.
- Don’t overmix the filling; whisk just until smooth to avoid incorporating excess air.
- Chill before cutting – once baked, refrigerate for at least 1 hour before slicing for cleaner, firm squares.
- Add a homemade crust – if time allows, a buttery, from-scratch crust will elevate the flavor and flakiness.
- Customize your spices – add a pinch of cardamom or allspice for a more complex flavor profile.
These details make the difference between a good pie and an unforgettable one.
