Sweet Potato Pie Recipe Using Flour: Crisp Crust and Silky Filling Harmony

This sweet potato pie recipe using flour delivers the perfect balance of crisp golden crust and velvety, spiced filling that tastes like autumn in every bite. 🍂 The secret lies in a well-balanced crust—flour-based but sturdy enough to hold its shape—while the filling gets its signature texture from properly mashed sweet potatoes and just the right amount of flour to thicken without heaviness.

What sets this recipe apart is the harmony between traditional techniques and modern convenience.

You'll start with a simple flour crust (or gluten-free alternative) that bakes to a beautiful golden brown, while the filling combines roasted sweet potatoes, warm spices, and a touch of flour to create that signature silky consistency.

The result is a pie that's rich enough to satisfy cravings but light enough to serve at gatherings.

Baking at 375°F for about 50-60 minutes ensures a perfectly set filling with a caramelized top, while a brief resting period lets the flavors meld. The crust stays crisp, the filling remains creamy, and every slice delivers that perfect blend of sweet, spicy, and velvety goodness.

This is dessert that feels special without requiring hours in the kitchen.

Whether you're making it for Thanksgiving, a holiday dessert spread, or a cozy weeknight treat, this recipe adapts beautifully. The flour-based crust gives you control over texture, and the filling's spice blend can be adjusted to suit your taste—warm cinnamon, nutmeg, or even a hint of ginger. Let's get baking!

Ingredients for sweet potato pie recipe using flour

Flour-based crust meets velvety sweet potato filling for a pie that balances tradition and modern ease.

The sweet potatoes are the foundation—Beauregard variety if you can find it, but any orange-fleshed will work. Roast them until tender (about 45 minutes at 400°F) and mash them smooth, no lumps. For the flour, King Arthur or Bob's Red Mill are reliable choices, and if you're making a gluten-free version, their blends work beautifully. The butter matters here too—use Plugrá or Land O'Lakes unsalted for the best flavor. If you're in a rush, frozen sweet potatoes (thawed and drained) work in a pinch, but fresh is ideal.

No evaporated milk? Whole milk reduced by half works, though the texture won't be quite as rich. Freshly ground spices make all the difference—Penzeys or bulk bins at Whole Foods are great sources. The flour in the filling acts as a thickener, so don't skip it, but if you're watching carbs, you can reduce it by 1/4 cup. For the crust, chilled butter is key—cut it into small cubes and keep them cold until mixing. If your dough feels too sticky, add 1 tbsp more flour. The vanilla extract should be pure, not imitation—McCormick Pure or Nielsen-Massey are solid choices.

The crust should rest for at least 30 minutes before baking to prevent shrinking. Once baked, let the pie cool completely before slicing—at least 2 hours—to avoid a runny filling. Store leftovers in an airtight container in the fridge for up to 5 days, or freeze for 3 months. Reheat slices in the oven at 350°F for 10 minutes to restore the crispness. The filling thickens as it cools, so if it seems too thin when first baked, don't worry—it'll set up beautifully.

Step-by-step instructions for sweet potato pie with flour-based crust

Here's how to create a perfect balance of crisp golden crust and velvety sweet potato filling.

Preheat your oven to 375°F. Peel and cube the 3 lbs sweet potatoes, then place them in a large pot of salted water. Bring to a boil and cook for 15-20 minutes until fork-tender. Drain well and transfer to a food processor or blender.

While still warm, add 1.5 cups granulated sugar, 2 whole large eggs, 1 cup evaporated milk, 2 tbsp ground cinnamon, 1 tsp ground nutmeg, 1 tsp ground ginger, 0.5 tsp salt, and 1 tbsp vanilla extract. Puree until completely smooth, scraping down the sides as needed. The mixture should be thick but pourable—if it's too thick, whisk in 1-2 tablespoons of water to reach the right consistency.

In a large bowl, combine 1.5 cups all-purpose flour (or 1.5 cups gluten-free flour blend for a gluten-free option) with 0.5 tsp salt. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This texture is crucial for a flaky crust.

Gradually add the 0.25 cup ice water one tablespoon at a time, mixing gently with a fork until the dough just comes together. Avoid overmixing—just combine until it holds when pressed. Divide the dough in half and flatten into two 8-inch rounds. Wrap each in plastic wrap and chill for 30 minutes while you prepare the pie dish.

Roll out one dough round on a lightly floured surface to fit a 9-inch pie dish. Press it gently into the bottom and up the sides, trimming any excess dough. Pour the sweet potato filling into the crust, spreading it evenly. Roll out the second dough round and place it on top, pressing the edges to seal. Cut a few slits in the top crust to allow steam to escape.

Here's the thing—I like to brush the top crust with a bit of evaporated milk mixed with a pinch of salt before baking. This creates a beautiful golden finish. Place the pie on a baking sheet to catch any drips and bake for 45-50 minutes until the crust is golden brown and the filling is set but still slightly jiggly in the center.

Remove the pie from the oven and let it cool completely on a wire rack. This cooling period is essential—it allows the filling to set properly and prevents a runny pie. The crust will firm up as it cools, and the filling will develop its signature silky texture. For best results, refrigerate for at least 2 hours before slicing.

When ready to serve, run a sharp knife around the edge to separate the pie from the dish. Slice into wedges and serve warm or at room temperature. The contrast between the crisp, flaky crust and the smooth, spiced filling makes every bite perfect. Store leftovers in the refrigerator for up to 3 days or freeze for up to 2 months.

Essential equipment for sweet potato pie recipe using flour

Flour-Based Crust Essentials

For a sturdy flour crust, you’ll need a 9-inch pie dish and a rolling pin—I love my OXO Good Grips rolling pin for even pressure. A pastry brush (like Norpro’s silicone one) helps with egg wash or milk brushing for that golden finish.

Don’t skip the pie weights or dried beans for pre-baking the bottom crust to prevent sogginess. 🍂

Filling Prep Tools

A food processor or immersion blender is key for smooth filling—avoid lumps at all costs! I use my Ninja BN601 for quick blending. For measuring, a liquid measuring cup (like Pyrex’s) ensures precise sugar and milk ratios.

A fine-mesh sieve helps sift spices like cinnamon and nutmeg for even distribution in the filling.

Baking Must-Haves

Your oven needs a baking sheet to catch drips, and a pie cooling rack prevents soggy bottoms. I swear by a digital thermometer (like Thermoworks Smoke) to monitor the oven’s accuracy—375°F is critical for even baking.

A sharp chef’s knife (I use Victorinox’s 8-inch) is essential for clean slices after cooling.

Gluten-Free Adaptations

If using a gluten-free flour blend, a stand mixer (like KitchenAid’s Artisan) helps blend ingredients evenly. A pie crust sealant (like Daisy brand) ensures a tight edge.

For thickeners, xanthan gum (½ tsp) in the filling prevents separation. Always chill the dough longer—45 minutes—since gluten-free crusts can be trickier to handle. ✨

Storage Solutions

For leftovers, airtight containers (like Rubbermaid’s Brilliance) keep slices fresh for 3 days. A parchment-lined container prevents sticking when freezing. To reheat, use a microwave-safe plate (like Pyrex’s) on 50% power for 30 seconds—or bake at 350°F for 10 minutes to restore crust crispness.
