The sweet potatoes are the heart of this pie, so look for vibrant orange ones at the store—they’re sweeter and creamier. Costco or Trader Joe’s usually carry the best quality, but any grocery store’s produce section will do. For the rum, Havana Club or Appleton Estate are my go-tos, but any dark rum (like Captain Morgan) works. The key is letting it infuse while roasting—don’t skip this step! If you’re using pre-made crust, chill it for 30 minutes before rolling to prevent shrinking. Homemade crust? Brush those lattice cuts with heavy cream for extra crispiness.
No dark rum? Substitute with 2 tbsp molasses plus 1 tsp vanilla extract—it mimics the depth. Short on sweet potatoes? Yams work in a pinch, but peel them first. The crust can be gluten-free if needed—just grab a pre-made GF package from King Arthur or Bob’s Red Mill. For extra richness, add 1 tbsp of butter to the filling while blending. And if you’re feeling fancy, toast your spices in a dry pan for 30 seconds before adding—they’ll sing with flavor. The filling should be thick but pourable; if it’s too stiff, add a splash more evaporated milk.
This pie tastes even better the next day, so bake it ahead if you’re hosting. Store leftovers covered at room temperature for 2 days or in the fridge for 5 days. For freezing, wrap tightly in plastic and thaw overnight in the fridge. The crust stays crispy if you reheat slices in a 350°F oven for 5 minutes. I always make two pies—one for now, one to freeze for Christmas morning. Trust me, the aroma alone is worth the effort.

Step-by-step instructions for rum sweet potato pie
Here's how to create a perfectly spiced, boozy filling with a golden, crispy crust every time.
Roast the Sweet Potatoes Until Tender
Preheat your oven to 375°F and line a baking sheet with parchment paper. Spread the 2.5 lb peeled and cubed sweet potatoes in a single layer, ensuring they're not crowded. Drizzle them with 0.25 cup of the dark rum (reserve the remaining 0.25 cup for later) and toss gently to coat. Roast for 25-30 minutes until the sweet potatoes are fork-tender and slightly caramelized at the edges.
I like to check for doneness by piercing a cube with a fork—it should slide in easily with just slight resistance. Don't skip this step; properly roasted sweet potatoes create the creamiest filling. If they're not tender enough, they'll make the pie filling watery.
Make the Boozy Filling
In a large mixing bowl, combine the roasted sweet potatoes with 1.25 cups granulated sugar, 0.5 cup unsalted butter, 2 whole large eggs, 1 cup evaporated milk, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 0.5 tsp salt, and 1 tsp vanilla extract. Using a hand mixer or electric mixer, blend everything until completely smooth and creamy.
Here's the thing—this is where the magic happens. The rum you reserved earlier gets stirred in now, adding that perfect boozy depth. Mix just until combined to avoid deflating the filling. The texture should be thick but pourable, like a rich pudding. If it looks too thick, add 1 tablespoon of evaporated milk at a time until it reaches the right consistency.
Prepare and Fill the Crust
Roll out the pie crust dough to fit a 9-inch pie dish, leaving a ½-inch overhang around the edges. Press it gently into the dish, then trim the excess dough, leaving about 1 inch for crimping later. Chill the crust in the freezer for 15 minutes while you preheat the oven to 350°F.
Pour the filling into the chilled crust, spreading it evenly. The filling should come up to about ½ inch from the top edge of the crust. Brush the overhanging dough with 0.25 cup heavy cream and sprinkle with a pinch of sugar to create that beautiful golden crust. This step is crucial for achieving that crispy, caramelized top you're after.
Bake to Golden Perfection
Place the pie on the middle rack of your oven and bake for 50-55 minutes. The filling should be set but still slightly jiggly in the center—it'll continue cooking as it cools. Watch the edges carefully; they should turn a deep golden brown before the center is fully set.
Here's where it gets exciting—when the pie comes out of the oven, the edges should be beautifully crispy, and the top should have a caramelized sheen. If the crust isn't as golden as you'd like, broil it for 1-2 minutes at the end, keeping a close eye to avoid burning. Let the pie cool completely on a wire rack before slicing—this ensures clean cuts and prevents a runny filling.
Serve with Confidence
Once the pie has cooled for at least 2 hours, it's ready to serve. The filling should be smooth, spiced to perfection, and infused with that warm rum flavor. Slice into wedges and serve with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate dessert experience.
Each bite should deliver a perfect balance of sweet, spiced sweet potatoes, a hint of boozy warmth, and that irresistible crispy crust. The pie keeps well in the refrigerator for up to 3 days, so you can enjoy it over several occasions. Trust me, this is the kind of pie that will have everyone asking for seconds!
Pro Tips For Making Rum Sweet Potato Pie
- ROAST POTATOES UNTIL TENDER: I learned this the hard way—sweet potatoes straight from the fridge won’t mash smoothly, no matter how much you beat them. Roast them at 400°F (200°C) for 45-50 minutes until a fork glides in like butter. The edges should pull away just slightly, but don’t overdo it or your pie filling gets grainy.
- USE FULL-FLAVOR RUM: Skip the cheap stuff—look for dark rum with at least 40% alcohol content (like Appleton Estate or Diplomatico). Reduce it first: simmer ¼ cup rum with 1 tablespoon brown sugar until syrupy (about 5 minutes). This concentrates the flavor and cuts the harshness. Trust me, your pie won’t taste like a college frat punch.
- WHISK EGGS LIKE YOUR LIFE DEPENDS ON IT: Don’t just crack and stir. Whisk the eggs until they’re pale, thick, and ribbon-like—this ensures a silky texture, not a lumpy mess. I used to skip this, and my pie always ended up with eggy clumps. Pro move: Temper the eggs by mixing them into the warm sweet potato mixture gradually, or you’ll risk scrambling them.
- BAKE LOW AND SLOW: Crank the oven to 350°F (175°C) and bake for 50-60 minutes—no peeking! Sweet potato pies need steady heat to develop that deep caramelized flavor without burning. If your edges brown too fast, tent loosely with foil, but leave the center uncovered. The filling should jiggle slightly in the middle when done—it’ll set as it cools.
Troubleshooting this recipe
Filling Too Thin
If your filling spreads too thin in the crust, it’s likely undercooked or overmixed. First, check your sweet potatoes—if they’re not fully tender after roasting, they’ll release excess moisture and thin the filling. Roast them until they collapse easily with a fork.
For extra richness, add 1 extra tablespoon of butter or 2 tablespoons of evaporated milk to thicken it. Stir in 1 teaspoon of cornstarch mixed with 1 tablespoon of water just before baking to bind the filling. 💡
Crust Too Soft
A soggy crust usually means the filling was too wet or the crust wasn’t pre-baked. To fix this, blind-bake your crust for 10 minutes at 375°F before adding the filling. Place a pie weight or dried beans inside the crust, then bake.
If you’re short on time, sprinkle ½ cup of crushed cornflakes or crushed graham crackers over the filling before baking to create a barrier. Chill the crust for 20 minutes before filling to prevent it from shrinking. 🥧
Rum Flavor Too Strong
Too much rum can overpower the sweetness. If your pie tastes harshly boozy, reduce the rum to ¼ cup or replace it with 2 tablespoons molasses + 1 teaspoon vanilla extract. For a subtler flavor, let the rum infuse while roasting the sweet potatoes—don’t add it all at once.
If the pie is already baked, balance the flavor by adding a pinch of cinnamon or nutmeg to the filling before serving. 🍹
Pie Not Setting Properly
A pie that doesn’t set properly is usually underbaked or overmixed. Ensure your filling reaches 160°F in the center before removing it from the oven. If it’s still jiggly after baking, return it to the oven for 5-10 more minutes.
For extra stability, add 1 extra egg yolk to the filling—it helps thicken as it bakes. Avoid overmixing, which incorporates too much air and prevents proper setting. 🔥
Sweet Potatoes Too Watery
If your filling looks thin and watery, your sweet potatoes were overcooked or not drained properly. After roasting, transfer the sweet potatoes to a colander and let them drain for 5 minutes before blending.
For extra insurance, pat them dry with a paper towel. If the filling is still too thin, simmer it on the stovetop for 5 minutes to evaporate excess moisture. 💧
Cracked Top
A cracked top often happens when the pie bakes too quickly or the oven isn’t hot enough. To prevent this, bake the pie on the middle rack for even heat distribution. If the filling is too hot when poured into the crust, chill it for 10 minutes before baking.
For a smooth finish, cover the filling with a thin layer of evaporated milk before baking—it creates a protective barrier. 🌟

Frequently asked questions
Can I make this pie without alcohol?
Replace the 0.5 cup dark rum with 2 tablespoons molasses plus 1 teaspoon vanilla extract for depth. The molasses mimics the caramelized warmth while keeping the pie rich and spiced. For a lighter touch, use 0.5 cup apple cider or orange juice instead.
How do I prevent a soggy bottom crust?
Prevent soggy crusts by blind-baking the crust for 10 minutes at 375°F before adding filling. Place a pie weight or dried beans inside, then bake. For extra insurance, sprinkle ½ cup crushed cornflakes or graham crackers over the filling before baking to create a moisture barrier. Always chill the crust for 20 minutes before filling.
What’s the best way to store leftovers?
Store the pie in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for 5 days or freeze for 3 months. To reheat, warm slices at 350°F for 5 minutes to restore crispiness. The flavor actually improves after 24 hours as the rum infuses further!
Can I use a different crust?
Yes! Try a gingersnap crust for extra spice, or a puff pastry for flakiness. For gluten-free options, use a pre-made crust from brands like King Arthur or Bob’s Red Mill. Just ensure the crust is fully chilled before filling to prevent shrinking. A lattice design works beautifully with this rich filling.
Why does my filling look grainy?
Graininess usually means the sweet potatoes weren’t smooth enough. After roasting, blend them with the filling ingredients until completely silky—use an immersion blender for best results. If using pre-cooked sweet potatoes, mash them thoroughly before adding other ingredients. For extra smoothness, strain the filling through a fine-mesh sieve if needed.
