Rum Sweet Potato Pie Recipe: Spiced Rum Infusion With Foil-Sealed Crust

This rum sweet potato pie recipe delivers the perfect balance of spiced sweetness and boozy depth—ideal for holiday tables or cozy gatherings. The secret lies in a slow-cooked rum reduction that infuses the filling with warm, aromatic notes, while a foil-sealed crust ensures a golden, flaky finish without overbaking.

I developed this version after years of testing, and the difference in flavor is transformative.

The filling starts with roasted sweet potatoes for natural sweetness, then simmers with brown sugar, warm spices, and a carefully reduced rum mixture. This method enhances the pie’s depth without overpowering its natural flavors.

The crust, made with a simple pie dough and sealed with foil, stays crisp while the filling sets to a velvety texture—no soggy bottoms here.

By the time it emerges from the oven, you’ll have a pie with layers of flavor: caramelized sweet potatoes, a hint of spiced rum, and a perfectly flaky crust.

The aroma alone will have everyone gathering around the table. Serve warm with whipped cream or a scoop of vanilla ice cream for the ultimate dessert experience.

This recipe scales beautifully for parties, and the rum reduction can be made ahead for convenience. Whether you’re a seasoned baker or trying your hand at pie for the first time, this version delivers professional results with simple techniques. Let’s get started!

Ingredients for rum sweet potato pie

Spiced rum, caramelized sweet potatoes, and a foolproof crust—this pie delivers holiday magic every time.

Ingredient Amount Notes
Medium Sweet Potatoes 🍠 4 whole Peeled and cubed evenly
Light Brown Sugar 🍚 1 cup Packed firmly for sweetness
Dark Rum 🍹 1 cup 180-proof preferred for depth
Unsalted Butter 🧈 ½ cup Cold, cubed for filling
Large Eggs 🥚 2 whole Room temperature for binding
All-Purpose Flour 🌾 ¼ cup For thickening filling
Ground Cinnamon 🌿 2 tsp Freshly ground preferred
Ground Nutmeg 🌿 1 tsp Freshly grated for warmth
Ground Ginger 🌿 ½ tsp Freshly ground for zing
Salt 🧂 ½ tsp Kosher or sea salt
Heavy Cream 🥛 ½ cup Full-fat for richness
Pie Dough 🥧 1 package Store-bought or homemade
Granulated Sugar 🍚 2 tbsp For sprinkling on crust

The rum is the star here—Captain Morgan Original or Bacardi 8 work best, but any dark rum will do. If you're nervous about alcohol flavor, reduce it on the stove until it's syrupy and aromatic (about 1/4 cup liquid left). Sweet potatoes should be firm, not waxy—Beauregard or Jewel varieties are perfect. Roast them first for natural sweetness, which cuts down on added sugar. I always buy mine from the produce section at Whole Foods when they're in season, but any grocery store carries them year-round.

No dark rum? Spiced rum at half the amount works in a pinch, or swap for apple cider reduced by half if you're avoiding alcohol entirely. Freshly ground spices make all the difference—Penzeys or McCormick are my go-tos, but the bulk bins at Trader Joe's are budget-friendly. For the crust, store-bought is fine (just make sure it's refrigerated, not frozen). Want to go homemade? A simple 3-ingredient dough with butter, flour, and ice water does the trick. The heavy cream can be swapped for half-and-half if you're watching fat, but trust me on the full-fat version for that velvety texture.

This pie tastes even better the next day, so bake it ahead if you can. Store leftovers in the fridge for up to 5 days, covered tightly. Reheat slices in a 350°F oven for 10 minutes to restore the crust's crispness. The filling freezes beautifully too—just thaw overnight in the fridge before serving. I always make an extra crust to serve on the side for seconds, because let's be honest, this pie disappears fast.

Step-by-step instructions for rum sweet potato pie

Here's how to make this rich, spiced pie with a foolproof foil-sealed crust.

1

Cook the Sweet Potatoes Until Tender

Preheat your oven to 375°F. Peel and cube the 4 whole medium sweet potatoes evenly into ½-inch pieces. Place them in a large bowl and toss with ½ cup unsalted butter and ½ teaspoon salt until fully coated. Spread the sweet potatoes on a rimmed baking sheet in a single layer.

Roast for 45-50 minutes, stirring halfway, until the potatoes are fork-tender and golden brown. You'll know they're done when they collapse easily under a fork's pressure. Let them cool slightly before draining any excess liquid through a fine-mesh strainer. This step ensures your filling will be smooth and flavorful without being watery.

2

Make the Rum-Spiced Filling

In a large mixing bowl, combine the cooled sweet potatoes with 1 cup light brown sugar, 2 teaspoons ground cinnamon, 1 teaspoon ground nutmeg, and ½ teaspoon ground ginger. Mix until the sugar is fully incorporated and the spices are evenly distributed. The filling should look thick and slightly sticky.

In a separate small bowl, whisk together 2 whole large eggs, ½ cup heavy cream, 1 cup dark rum, and ¼ cup all-purpose flour. Slowly pour this mixture into the sweet potato mixture, stirring gently until fully combined. The rum will infuse the filling with deep, warm notes, but don't worry if the mixture looks slightly curdled—it will smooth out as it bakes.

3

Assemble and Bake the Pie

Roll out the 1 package pie dough on a lightly floured surface to fit a 9-inch pie dish. Press it gently into the dish, letting the edges hang over the sides. Pour the filling into the crust, mounding it slightly in the center. Sprinkle 2 tablespoons granulated sugar evenly over the top for a touch of caramelized sweetness.

Place the pie on a baking sheet (to catch any drips) and bake at 375°F for 50-55 minutes, until the filling is set but still slightly jiggly in the center. The crust should be golden brown, and the edges should be puffed and flaky. If the crust starts to brown too quickly, loosely cover it with aluminum foil.

4

Finish with Foil-Sealed Crust

Once the filling is mostly set, remove the pie from the oven and let it cool for 10 minutes. This resting period helps the filling firm up slightly before the final step. While it cools, cut a large sheet of aluminum foil and place it over the entire pie, pressing it gently against the crust.

Return the pie to the oven and bake for an additional 10-15 minutes at 350°F. This foil-sealed step ensures the crust stays crispy and flaky while the filling continues to set. When you remove the pie, let it cool completely on a wire rack before slicing. The contrast of the warm, spiced filling and the crisp crust is what makes this pie truly special.

Pro Tips For Making Rum Sweet Potato Pie

  • Boil Until Fork-Tender: Sweet potatoes should collapse like butter when pierced—not just soft. I learned this the hard way: undercooked chunks turn your pie into a sad, gummy mess. Test one after 20 minutes; if it’s still springy, add another 10.
  • Toast the Rum: Skip the pour-and-stir approach. Heat 2 tablespoons of rum in a small pan until it smells like caramelized heaven (about 2 minutes), then swirl it into the filling. This deepens the flavor and cuts the alcohol bite—trust me, your pie will taste richer.
  • Beat Eggs Like You Mean It: Whisk those eggs until they’re thick enough to hold a ripple when you lift the whisk. I used to rush this, and the pie filling would split like a bad joke. A few extra seconds now means no weeping custard later.
  • Chill Before Baking: Let the filling sit uncovered in the fridge for at least 2 hours—yes, even if you’re impatient. This lets the flavors meld and prevents a dense, rubbery texture. I know, I know, but trust the process: your pie will thank you with a silky, golden top.

Perfect pairings for this rum sweet potato pie

Creamy Toppings

Whipped cream is a classic choice—lightly sweetened with 1 tablespoon powdered sugar and a splash of vanilla extract. I often add a pinch of ground cinnamon to echo the pie’s spiced notes.

For extra decadence, try coconut whipped cream or a dollop of vanilla bean ice cream—the cool contrast balances the warm pie perfectly. 🥛

Boozy Enhancements

Serve with a small glass of the same dark rum you used in the pie—Captain Morgan or Bacardi 8 work beautifully. The smoky, caramel notes complement the spiced filling.

For a non-alcoholic twist, offer spiced apple cider or ginger tea to enhance the warm flavors without overpowering the dessert. 🍹

Crunchy Contrasts

Add a sprinkle of toasted pecans or candied walnuts on top for texture. Toast ½ cup pecans in a dry skillet over medium heat for 3-4 minutes until fragrant, then toss with 1 tablespoon brown sugar and ½ teaspoon cinnamon.

The nutty crunch cuts through the creamy filling beautifully. 🌰

Seasonal Variations

In fall, garnish with caramelized apples—thinly slice 1 apple, cook in 1 tablespoon butter with ½ teaspoon cinnamon until soft, then arrange on top. For winter, a dusting of powdered sugar or a drizzle of honey adds a touch of elegance. 🍎

Coffee Pairings

Pair this pie with a strong dark roast coffee or espresso to cut through the richness. A splash of vanilla syrup in your coffee enhances the pie’s warm spices.

For a festive touch, serve with mulled wine—simmer 1 cup red wine with ½ cup orange juice, 1 cinnamon stick, and 2 star anise pods for 10 minutes**. 💛

Frequently asked questions

1

Can I make this pie without alcohol?

Replace the 1 cup dark rum with ½ cup apple cider reduced by half on the stove. Simmer the cider in a small saucepan until it thickens slightly and develops caramelized notes—this mimics the rum's depth. For extra warmth, add ½ teaspoon cinnamon and ¼ teaspoon ginger while reducing. The flavor will still be rich and aromatic!

2

Why does the crust need foil sealing?

The foil-sealed crust trick prevents sogginess while keeping the edges crisp. When the filling sets, it releases moisture that can soften the crust. The foil traps heat, allowing the filling to finish cooking while shielding the crust from steam. Remove it 10-15 minutes before the final bake to let the crust crisp up beautifully. It’s a game-changer for texture!

3

How do I store leftovers to keep the crust crisp?

Store slices in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. To revive the crust, reheat slices in a 350°F oven for 10 minutes with a sprinkle of water on top—this creates steam that crisps the edges again. Freezing isn’t recommended for this pie, as the filling can become watery when thawed.

4

What’s the best way to adjust the sweetness?

Start with the recipe as written, then taste the filling before baking. If it needs more sweetness, add 1-2 tablespoons brown sugar or 1 tablespoon maple syrup. For depth, reduce the rum further until only ¼ cup liquid remains—this concentrates the flavor without adding sweetness. The roasted sweet potatoes already provide natural sweetness, so adjust gradually!

5

Can I use regular potatoes instead of sweet potatoes?

No, this recipe relies on sweet potatoes for their natural sweetness, moisture, and velvety texture. Regular potatoes (like Russets) are starchy and dry, which would make the filling gummy. If you’re set on using them, roast until very tender, then mash them thoroughly to mimic the sweet potato’s consistency—but expect a less rich flavor. Stick with sweet potatoes for the best results!
