Rum Sweet Potato Pie Recipe: Boozy Spice and Silky Texture Magic

This rum sweet potato pie recipe delivers the perfect balance of spiced sweetness and rich, boozy depth—every slice is a celebration of autumn flavors. The secret lies in slow-cooked sweet potatoes infused with rum, creating a silky filling that’s both velvety and fragrant.

I’ve perfected this technique over years of baking, ensuring the crust stays crisp while the center remains just set—no soggy surprises here.

What sets this pie apart is the rum’s ability to deepen the natural sweetness of the sweet potatoes while adding warmth and complexity. A classic custard base ensures smooth texture, and the spice blend—cinnamon, nutmeg, and ginger—elevates every bite.

Whether you use a homemade crust or opt for store-bought, the result is a pie that tastes like comfort and tradition. The filling is rich but not heavy, with just the right amount of boozy brightness.

Baking at 350°F for 50-60 minutes guarantees a golden crust and a filling that’s tender but firm enough to slice cleanly. The aroma alone—warm spices mingling with rum—will have your kitchen smelling like a cozy holiday gathering.

Serve it with a dollop of whipped cream or a drizzle of caramel for extra indulgence. This pie is the centerpiece every dessert table deserves.

For those avoiding alcohol, a rum extract or extra vanilla can mimic the depth, but nothing compares to the real thing. The key is patience: letting the filling cool slightly before assembling prevents leaks, and a water bath ensures even baking.

Trust me, the first slice will be worth every minute of effort.

Ingredients for rum sweet potato pie

Sweet potatoes, rum, and spices—this pie needs just 14 ingredients for bold autumn flavor.

The sweet potatoes are non-negotiable. Orange-fleshed varieties like Beauregard are ideal—they’re naturally sweet and hold their shape. I always grab a 2.5 lb bag from Trader Joe’s (they’re pre-peeled and cubed for convenience), but you can peel and cube your own. For the rum, Havana Club 7-year or Captain Morgan Original add depth without overpowering. If you’re avoiding alcohol, a vanilla bean extract or extra vanilla extract works, though it won’t replicate the boozy warmth. The spices? Penzeys or bulk bins at Whole Foods have the freshest ground varieties—nutmeg and ginger lose potency fast once opened.

No rum? Substitute with vanilla extract plus a splash of bourbon or apple cider for a similar depth. The heavy cream and evaporated milk combo is key—don’t swap for lighter milk, or the filling will curdle. For the crust, store-bought pie crust (like Pillsbury) saves time, but a homemade one with Diamond Crystal kosher salt adds that professional touch. If you’re making your own dough, chill it for at least 30 minutes—this prevents shrinking. The vanilla extract should be pure, not imitation. McCormick or Nielsen-Massey are reliable brands. And if your filling seems too thin, simmer it uncovered for 5 minutes to thicken slightly before baking.

Sweet potatoes keep 1 week in the fridge, peeled or unpeeled. The rum can be stored in the pantry indefinitely, but once opened, keep it sealed tightly. For the crust, wrap it in plastic and refrigerate until ready to use—it’ll stay fresh for 3 days. The filling can be prepped a day ahead and refrigerated, but let it sit at room temp for 30 minutes before baking. Once baked, this pie tastes even better the next day—slice and serve with a dollop of homemade whipped cream or a drizzle of salted caramel for that extra touch of indulgence.

Step-by-step instructions for rum sweet potato pie

Here's how to create the perfect balance of spiced sweet potato filling and buttery crust.

Preheat your oven to 375°F. In a large bowl, combine the peeled and cubed 2.5 lb sweet potatoes, 0.5 cup dark rum, 1.25 cups granulated sugar, 2 whole large eggs, 1 cup heavy cream, 1 cup evaporated milk, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 0.5 tsp ground ginger, and 0.5 tsp salt. Mix until the sweet potatoes are thoroughly coated and the sugar dissolves completely.

Transfer the mixture to a 9-inch pie dish and bake for 45-50 minutes until the filling is set and the top is golden brown. You'll know it's done when the center barely jiggles and the edges pull away slightly from the dish. Let it cool completely before adding the topping—this prevents the crust from getting soggy.

In a large bowl, combine 1.5 cups all-purpose flour, 0.5 cup cold unsalted butter (cut into small cubes), 0.33 cup ice water, and 1 tbsp vanilla extract. Using a pastry cutter or your fingers, work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.

Gradually add the ice water, 1 tablespoon at a time, mixing gently with a fork until the dough just comes together. Be careful not to overwork it—just until it holds when pressed. Form the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 1 hour. This chilling step is crucial for a flaky crust.

Roll out the chilled dough on a lightly floured surface to fit a 9-inch pie dish. Carefully transfer it to the dish, trimming any excess dough. Press the edges to create a slight rim, and crimp decoratively if desired. Prick the bottom of the crust with a fork to prevent air pockets.

Place the assembled pie on a baking sheet lined with parchment paper (to catch any drips) and bake at 375°F for 20-25 minutes until the crust is golden brown and puffed. Remove from the oven and let it cool slightly before slicing. The warm pie will be even more delicious—serve it with a dollop of whipped cream or a scoop of vanilla ice cream.

Allow the pie to cool completely at room temperature for at least 2 hours before slicing. This resting period lets the filling set properly and makes for cleaner slices. The rum flavor will mellow slightly as it cools, creating a perfect balance of spice and sweetness.

When ready to serve, cut into 8 equal slices using a sharp knife or pie server. Each slice should reveal a silky, spiced filling with a perfectly golden crust. The rum adds a subtle warmth that pairs beautifully with the natural sweetness of the sweet potatoes, making this pie a showstopper for any dessert table.

Best sauces and condiments for this rum sweet potato pie

Classic Bourbon Caramel

Drizzle 2 tbsp bourbon caramel sauce (like Smucker’s or homemade) over each slice for a rich, buttery contrast to the rum. Heat ½ cup heavy cream with ½ cup brown sugar and ¼ cup bourbon until dissolved, then simmer for 5 minutes until thickened.

The bourbon’s vanilla notes complement the rum beautifully. 🍯

Spiced Whipped Cream

Whip 1 cup heavy cream with 1 tbsp powdered sugar, ½ tsp cinnamon, and ¼ tsp nutmeg until soft peaks form. Fold in 1 tsp rum for an extra boozy kick.

This adds airy texture and ties into the pie’s spice profile. Store in an airtight container for up to 3 days.

Salted Caramel Drizzle

Melt ½ cup caramel sauce with ¼ cup heavy cream and 1 tsp flaky sea salt (like Maldon). Drizzle over slices while warm for a salty-sweet balance. The salt enhances the rum’s warmth, cutting through the sweetness. Use 2 tbsp per pie for perfect coverage. ✨

Vanilla Bean Ice Cream

Serve with vanilla bean ice cream (like Ben & Jerry’s) to cool the rum’s warmth. The creamy texture contrasts the pie’s custard filling. For extra indulgence, swirl 1 tsp rum into the ice cream before serving. A scoop per slice is ideal for portion control. 🍦

Coconut Whipped Cream

For a tropical twist, whip 1 cup coconut cream with 1 tbsp powdered sugar and ½ tsp vanilla. The coconut’s sweetness pairs surprisingly well with rum’s depth. Chill for 1 hour before serving to achieve fluffy peaks. 🥥

Lemon Curd Swirl

Mix ½ cup lemon curd (like Bon Appétit’s recipe) with 1 tbsp whipped cream, then swirl into the pie before baking. The tartness brightens the rum’s richness. Use 2 tbsp per pie—too much overpowers the sweet potato flavor. 🍋
