Desserts
This sweet potato pie with marshmallow meringue recipe delivers the perfect balance of spiced filling and cloud-like topping—every slice is a warm hug of cinnamon and toasted marshmallow magic. 🔥 The secret lies in a velvety purée that blends sweet potatoes, eggs, and warm spices, then crowns it with a meringue so light it practically dissolves on your tongue.
I've perfected this technique over years of holiday baking, ensuring the meringue stays stable through baking while achieving that signature toasted finish.
The filling begins with roasted sweet potatoes for natural sweetness and smooth texture, while the meringue topping gets its signature gooeyness from a mix of whipped egg whites, sugar, and mini marshmallows. The key to success?
A gentle broil at the end to toast the marshmallows just enough for that caramelized contrast without burning. This isn't your average pie—it's a showstopper that tastes like autumn in every bite, with a crust so buttery it disappears completely.
What makes this recipe truly special is how the flavors come together: the warm spices of the filling play beautifully against the sweet, toasted meringue, creating a dessert that's both comforting and impressive.
The marshmallow layer adds a playful texture that kids and adults alike will love, while the spiced sweet potato base ensures it's satisfying enough to be a main dessert course. Perfect for Thanksgiving tables or holiday gatherings, this pie is the centerpiece that steals every show.
For best results, let the pie cool slightly before slicing to maintain that perfect meringue structure, and always broil carefully to avoid over-browning. Serve with a dollop of whipped cream or vanilla ice cream to enhance the flavors even further. Here's everything you need to create this crowd-pleasing masterpiece!

Sweet potatoes are the heart of this pie, so pick firm, vibrant ones—no soft spots. I always roast mine first for that natural sweetness and smooth texture. Trader Joe's has the best organic sweet potatoes if you're splurging, but regular ones work too. For the crust, Pillsbury refrigerated dough is my go-to—no rolling required. If you're ambitious, homemade crust with extra butter makes it even more decadent. The marshmallows? Mini marshmallows are a must—they toast perfectly and don't get too gooey.
No mini marshmallows? Regular marshmallows chopped into small pieces work in a pinch, but they won't toast as nicely. Short on egg whites? Pasteurized liquid egg whites from the grocery store save the day. The spices are non-negotiable for that warm, cozy flavor—Penzeys has the best pre-ground spices if you want to splurge. For the sugar, if you don't have superfine, just pulse regular sugar in a food processor until it's fine. And trust me, room temperature eggs mix so much better—they blend like butter.
This pie tastes even better the next day once the marshmallows fully set. Store leftovers in the fridge for 4-5 days—just reheat in the oven for 10 minutes to revive that toasted marshmallow magic. Freezes beautifully for up to 3 months if you want to make it ahead. I always bake mine a day before serving so the meringue can develop its signature toasted flavor. And pro tip: Broil those marshmallows carefully—watch them like a hawk to avoid burning!
Why You'll Love This Recipe
- No Pudding Pan Needed: I swear by this trick—just mash those roasted sweet potatoes right in the pie dish with the eggs and sugar. No extra mixing bowls, no sticky mess, and the texture comes out perfectly creamy every time. The evaporated milk adds that rich, velvety touch without fuss.
- Marshmallow Magic: That gooey meringue on top? It’s the star. The contrast of warm, spiced sweet potato filling melting under the toasted marshmallow topping is ridiculously satisfying. I’ll be real: I’ve been known to eat it straight from the oven with a spoon.
- Holiday or Weeknight: Between us, this pie works for Thanksgiving and lazy Sundays. The same simple base—sweet potatoes, eggs, and sugar—feels festive with a dusting of cinnamon or becomes a comforting dessert when you skip the pie crust entirely. (Yes, even on a Tuesday night.)
- Leftovers? More Like Leftovers: This recipe actually improves the second day. The meringue softens just enough to be pillowy, and the filling sets into a luscious, almost pudding-like texture. I’ve sent slices to work in jars, and no one’s ever complained—just asked for the recipe. Budget-friendly? Absolutely. Worth it? Even more so.
Step-by-step instructions for sweet potato pie with marshmallow meringue
Here's how to create the perfect pie with a toasted meringue crown and gooey marshmallow center.
🍳 Step 1: Cook the Sweet Potato Filling to Silky Perfection
Preheat your oven to 375°F. In a large pot, combine the 2.5 lbs peeled and cubed sweet potatoes, 1 cup evaporated milk, 0.5 cup melted butter, 1.5 cups granulated sugar, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 0.5 tsp ground ginger, 0.5 tsp salt, and 1 tsp vanilla extract. Bring to a boil over medium-high heat.
Once boiling, reduce heat to medium-low and simmer uncovered for 20-25 minutes until the sweet potatoes are fork-tender. Stir occasionally to prevent sticking. The mixture should thicken into a smooth, velvety consistency—it should coat the back of a spoon but still be pourable. If it thickens too much, whisk in 1-2 tablespoons of water to reach the perfect texture.
👨🍳 Step 2: Prepare the Meringue Mixture for Cloud Magic
While the filling cooks, separate the 5 whole large egg whites from the yolks. In a clean, grease-free bowl, beat the egg whites on medium speed until soft peaks form. Gradually add the 1 cup superfine sugar while continuing to beat on high speed for 5-7 minutes until the meringue is glossy and holds stiff peaks.
In a separate bowl, whisk together the 4 whole large eggs and the cooked sweet potato filling until fully combined and smooth. Here's the thing—this mixture needs to be completely homogeneous so the pie fills evenly. I like to strain it through a fine-mesh sieve to eliminate any lumps that might affect the texture.
🥘 Step 3: Assemble the Pie with Precision
Roll out the pre-made pie crust to fit a 9-inch pie dish, leaving a ½-inch overhang on all sides. Press it gently into the dish, then trim and crimp the edges. Pour the sweet potato filling into the crust, spreading it evenly. Sprinkle the 2 cups mini marshmallows evenly over the top of the filling.
Carefully spread the meringue over the marshmallows, sealing it to the crust edges to prevent shrinking. I use a spatula to press gently where the meringue meets the crust—this creates that perfect, crispy barrier. The meringue should completely cover the marshmallows with about ¼-inch thickness on top. Use the back of a spoon to create decorative peaks or swirls if you're feeling fancy!
🔥 Step 4: Bake to Golden Glory
Place the pie on the center rack of your preheated 375°F oven. Bake for 15 minutes, then reduce heat to 350°F and continue baking for an additional 40-45 minutes until the meringue is golden brown and the filling is set. The edges should be beautifully toasted while the center remains soft and gooey—this is where the magic happens!
Here's the crucial part: Watch the meringue closely during the last 5 minutes of baking. If it starts to brown too quickly, tent the pie with aluminum foil to prevent burning. The pie is done when the meringue is golden brown and the filling jiggles slightly when shaken but doesn't wobble excessively. Let it cool completely on a wire rack before slicing.
⏰ Step 5: Rest and Serve for Maximum Enjoyment
Allow the pie to rest at room temperature for at least 2 hours before serving. This resting period lets the filling set completely and the flavors meld together. The marshmallows will soften into a perfect gooey layer, and the meringue will develop that beautiful toasted flavor without becoming dry.
Slice with a sharp knife and serve warm for that perfect balance of creamy filling, toasted meringue, and marshmallow clouds. Each bite should deliver that perfect combination of spiced sweet potatoes, rich custard, and airy meringue. Trust me, the wait is worth it—this pie tastes even better after resting!
Pro Tips For Making Sweet Potato Pie With Marshmallow Meringue
- Boil Sweet Potatoes Until Tender: Sweet potatoes should break apart like mashed potatoes when pierced with a fork—no fight left. I learned this the hard way: undercooked ones turn the filling grainy, and overcooked ones make it watery. Aim for 20-25 minutes in salted water, then drain and cool completely before mashing.
- Cool Mashed Filling Fully: Skip the rush and let that filling sit at room temp for at least 30 minutes before baking. I was skeptical until I tried it—cooling prevents the custard from curdling when it hits the oven, and the texture stays silky instead of separating. (Yes, even if you're impatient like me.)
- Bake Low and Slow: 325°F is your friend here—don’t crank the oven higher to save time. After 45 minutes, tent the pie with foil and bake another 15-20 minutes. The center should jiggle slightly when shaken; it’ll set as it cools. Rushing leads to a dense, gummy filling that ruins the marshmallow meringue’s magic.
- Toast Marshmallows Gradually: Start the meringue at 350°F for 5 minutes, then drop to 300°F. This gradual heat prevents the marshmallows from burning before they puff. I used to blast them at high heat—now I get golden, toasty peaks instead of charred disappointment. Watch closely after the first 10 minutes.
Storing and reheating this dish
Refrigerator Storage
Store your leftover sweet potato pie in an airtight container or wrap it tightly with plastic wrap and a foil cover to prevent drying. Keep it refrigerated for up to 4-5 days—the marshmallow meringue will firm up slightly but still deliver that signature gooey texture when warmed.
I always let it sit at room temperature for 10 minutes before slicing to prevent the meringue from cracking. 🥧
Freezer Prep Tips
For long-term storage, wrap the pie in heavy-duty aluminum foil and place it in a freezer bag to lock in moisture. Freeze for up to 3 months—the meringue and marshmallows will stay perfectly intact.
When ready to serve, thaw overnight in the fridge, then warm in the oven for 15-20 minutes at 350°F to restore that toasted magic. ❄️
Oven Reheating
Preheat your oven to 350°F and place the pie on a baking sheet. Cover loosely with aluminum foil to prevent over-browning while warming through. Heat for 15-20 minutes until the meringue is lightly toasted and the filling is warm throughout.
This method preserves the marshmallow layer perfectly—no soggy texture here! 🔥
Microwave Caution
If you're short on time, microwave individual slices for 10-15 seconds on medium power—just enough to soften the meringue without turning it rubbery. Cover with a damp paper towel to prevent drying.
I don't recommend microwaving the whole pie, as it can create hot spots that ruin the delicate meringue structure. 🍴
Broiler Finishing
For that restaurant-quality toasted finish, place reheated slices under a broiler for 1-2 minutes—watch closely! The meringue will crisp up beautifully while the marshmallows stay gooey. This is my secret weapon for reviving pie that's been stored for a few days.
Just be prepared to work fast—broilers can turn meringue to charcoal in seconds. ⚡
Serving Warm
Serve warm slices with a dollop of whipped cream or a scoop of vanilla ice cream to enhance the marshmallow and meringue layers. The contrast of cold and warm creates the perfect bite—creamy filling, toasted meringue, and gooey marshmallow all working together.
Trust me, this is the only way to enjoy it! 💛

Frequently asked questions
Can I make this pie without a pre-made crust?
For a homemade crust, use a classic pie dough recipe with 2 ½ cups all-purpose flour, 1 tsp salt, ½ cup cold butter, and 6-8 tablespoons ice water. Roll it out to ⅛-inch thickness and fit it into a 9-inch pie dish. Chill for 30 minutes before filling to prevent shrinking. The extra butter makes it even more flavorful!
Why did my meringue collapse during baking?
Meringue collapses most often from humidity, over-whipping, or high oven temps. First, ensure your egg whites are completely room temperature and your bowl is grease-free. Beat them to stiff peaks (not glossy) and add sugar gradually. Bake at 350°F or lower and avoid opening the oven door during baking. If it collapses, try again with a drier day or use a meringue stabilizer like corn syrup (1 tsp).
Can I substitute regular marshmallows for mini marshmallows?
Regular marshmallows can work, but they won't toast as evenly or achieve the same gooey texture. If substituting, chop them into ¼-inch pieces and spread them slightly thicker than mini marshmallows (about ½-inch layer) to compensate for their larger size. They'll still soften beautifully but may not toast as nicely. For best results, stick with mini marshmallows—they're designed for this exact technique!
How do I make this pie ahead of time?
This pie actually tastes better when made 1-2 days ahead! Bake it completely, then store it at room temperature (covered loosely) for up to 24 hours to let flavors meld. For longer storage, refrigerate for 3-4 days or freeze for up to 3 months. Thaw overnight in the fridge before reheating. The meringue will firm up but still deliver that signature toasted flavor when warmed. Perfect for holiday prep!
What's the best way to serve leftover slices?
Reheat individual slices under a broiler for 1-2 minutes for that perfect toasted meringue finish, or warm in the oven at 350°F for 10-15 minutes covered loosely with foil. Serve with a dollop of whipped cream or a scoop of vanilla ice cream to enhance the marshmallow layer. The contrast of warm pie and cold toppings creates the ultimate texture experience!
