Ingredients for sweet potato pie with marshmallow meringue
Eight ingredients for the filling, three for the meringue—simple but spectacular results every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 ½ lbs | Canned or cooked, mashed smooth |
| All-Purpose Flour 🌾 | 1 cup | For pie crust, sifted |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crust |
| Granulated Sugar 🍚 | 1 ½ cups | For filling, light brown preferred |
| Evaporated Milk 🥛 | 1 can | 12 oz can, full-fat preferred |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| Pure Vanilla Extract 🌿 | 2 tsp | High-quality, no alcohol |
| Ground Cinnamon 🌶️ | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌶️ | ½ tsp | Freshly grated for depth |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Granulated White Sugar 🍚 | 1 cup | For meringue, superfine preferred |
| Meringue Powder 🍯 | 1 tsp | Or 1 egg white, beaten stiff |
| Unsalted Butter 🧈 | ¼ cup | Melted, for meringue |
The sweet potatoes are the heart of this pie, so pick firm, vibrant ones—no soft spots. Canned works in a pinch, but homemade mashed potatoes give you that restaurant-quality texture. For the crust, store-bought is fine (like Pillsbury), but if you're feeling ambitious, a homemade all-butter crust makes all the difference. The butter should be cold—wrap it in parchment paper and freeze for 20 minutes if it's too soft. And that evaporated milk? Full-fat is non-negotiable—it keeps the filling rich and creamy.
No meringue powder? Fresh egg whites are the way to go—whip them until they form stiff peaks, then fold in the sugar gradually. Running out of vanilla extract? Vanilla bean paste works too, just use half the amount. The nutmeg is where flavor magic happens—freshly grated (not pre-ground) adds a depth that jarred spices can't match. For the crust, if you're using store-bought, press it firmly into the pan and chill for 30 minutes before baking to prevent shrinking. And trust me, don't skip the two-stage baking—that's what keeps the meringue fluffy and golden without burning.
The filling keeps for 3 days in the fridge, but the meringue topping is best made fresh. If you're prepping ahead, bake the crust, fill it, and refrigerate the unbaked pie for up to 24 hours. For the meringue, spread it quickly—it starts to dry within minutes. Store leftovers in an airtight container (just the filling, since meringue doesn't reheat well) for 4 days. Freeze the filling for 3 months if you're planning ahead—thaw overnight in the fridge before baking.
Why You'll Love This Recipe
- No-Bake Magic: I swear by this when I’m too tired to bake—just boil the sweet potatoes, mix the filling, and let the marshmallow meringue do all the work. The oven does the heavy lifting while I sip coffee.
- Creamy-Sweet Symmetry: That velvety sweet potato base with evaporated milk and butter? It’s like a hug in dessert form, but the toasted marshmallow meringue on top adds a caramelized crunch that’s ridiculously satisfying.
- Holiday or Hangry Fix: Between us, this is my go-to for Thanksgiving and when I’ve forgotten to grocery shop. The same recipe works for a fancy dinner or a 7 PM emergency dessert—no judgment if it’s the latter.
- Leftovers? More Like Leftovers: Honestly, I make a double batch because the pie reheats beautifully (yes, even the meringue). It’s also cheaper than store-bought—sweet potatoes stretch farther than you’d think, and the sugar/butter ratio keeps it rich without breaking the bank.
Step-by-step instructions for sweet potato pie with marshmallow meringue
Here's how to create the perfect sweet potato pie with a fluffy meringue topping that stays light and never burns.
Prepare the Sweet Potato Filling
Begin by boiling or steaming the 2.5 lbs sweet potatoes until fork-tender, about 20-25 minutes. Drain well and let them cool slightly before scraping out the flesh. I like to use a ricer for ultra-smooth texture, but a potato masher works too.
Transfer the mashed sweet potatoes to a large mixing bowl. Add the 1.5 cups granulated sugar, 1 can evaporated milk, 2 whole large eggs, 2 tsp pure vanilla extract, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.5 tsp salt. Whisk everything together until completely smooth and well combined. The mixture should be thick but pourable—this is your perfect filling consistency.
Make the Pie Crust
In a separate bowl, combine the 1 cup all-purpose flour and 0.5 tsp salt. Cut in the 1 cup unsalted butter (cold and cubed) using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Gradually add 3-4 tablespoons ice water, mixing just until the dough comes together.
Wrap the dough in plastic and chill for 30 minutes while you preheat your oven to 375°F. Roll out the chilled dough on a floured surface to fit a 9-inch pie dish, then transfer it carefully to the dish. Trim and crimp the edges, then prick the bottom with a fork. Line with parchment paper, fill with pie weights, and blind-bake for 15 minutes before removing the weights and baking another 5 minutes until lightly golden.
Assemble and Bake the Pie
Pour the sweet potato filling into the pre-baked crust, spreading it evenly. The filling should come about ½ inch from the top edge. Bake uncovered at 375°F for 45-50 minutes, until the filling is set but still slightly jiggly in the center. This ensures it continues cooking while the meringue bakes.
Here's the thing—don't overbake. You want the filling to be just set, not firm. The meringue will add additional baking time, so pull the pie when the center still has a slight wobble. Let it cool completely on a wire rack before adding the meringue.
Create the Perfect Meringue Topping
In a separate bowl, beat the egg whites (from the 2 whole large eggs) to soft peaks. Gradually add the 1 cup granulated white sugar and 1 tsp meringue powder, beating until stiff, glossy peaks form. The meringue should be thick enough to hold its shape when spread.
Spread the meringue over the cooled pie filling, sealing it completely to the crust edge to prevent burning. For extra fluffiness, I like to pipe decorative swirls on top. Bake at 350°F for 10-12 minutes, until the meringue is golden brown and set. Watch closely—the meringue burns quickly once it turns golden.
Cool and Serve
Remove the pie from the oven and let it cool completely on a wire rack. This gradual cooling prevents the meringue from collapsing. For best results, refrigerate the pie for at least 4 hours before serving—this allows the filling to fully set and the flavors to meld.
Slice into wedges and serve with a dollop of whipped cream if desired. The meringue should be light and fluffy, with a crisp exterior and soft center. Each bite delivers that perfect balance of spiced sweet potato filling and sweet marshmallow topping—no soggy bottoms or burnt tops here!
Pro Tips For Making Sweet Potato Pie With Marshmallow Meringue
- Boil Until Fork-Tender: Sweet potatoes straight from the oven? No—boil them first. Cut into even 1-inch cubes, drop into salted boiling water, and cook until they collapse like overripe fruit (about 12-15 minutes). I learned this the hard way after mashing lumpy, undercooked chunks that turned my pie filling into a sad, grainy sludge. The texture matters more than you think.
- Toast the Flour: Skip the raw flour shortcut—lightly toast yours in a dry pan over medium heat for 2-3 minutes until it smells nutty. Stir constantly or it’ll burn. This step cuts the flour’s raw taste and thickens the filling better than just mixing it in cold. My grandmother swore by this, and she was right: the pie’s flavor pops when you do this.
- Don’t Overmix the Filling: Once you blend the sweet potato purée with eggs, sugar, and spices, stop stirring the second everything’s just combined. Overmixing introduces air, which makes the filling rise unevenly in the oven and can lead to cracks when you top it with meringue. I was skeptical until I tried it—now I resist the urge to "get it perfect."
- Bake in Two Stages: First, bake the pie filling at 350°F (175°C) for 20 minutes uncovered. Then, lower the heat to 325°F (165°C), add the meringue, and finish baking until golden. This two-step approach prevents the meringue from browning too fast or collapsing from the heat. Sounds weird, but it works: the pie stays creamy inside while the top gets that perfect toasty sheen.
Health benefits of sweet potato pie with marshmallow meringue
Fiber-Rich Comfort
Sweet potatoes are a nutritional powerhouse, delivering a whopping 7 grams of fiber per serving—that’s nearly 30% of your daily needs in one slice. This fiber supports healthy digestion and helps stabilize blood sugar levels, making this pie a surprisingly balanced dessert.
The natural sweetness from the potatoes also means you can reduce added sugar slightly without sacrificing flavor. 🍠
Vitamin A Boost
One slice of this pie provides over 100% of your daily vitamin A from the sweet potatoes, thanks to their beta-carotene content. Vitamin A is essential for vision, immune function, and skin health—so you’re getting a beauty and health boost with every bite.
The marshmallow meringue adds a sweet contrast without compromising these benefits.
Protein for Dessert
Don’t let the sweet fool you—this pie actually contains about 5 grams of protein per slice thanks to the egg whites in the meringue and whole eggs in the filling. Most desserts offer little to no protein, so this is a rare treat that still supports muscle maintenance and satiety.
It’s the perfect way to end a meal without the post-sugar crash.
Antioxidant Benefits
The cinnamon and nutmeg in the filling aren’t just for flavor—they’re packed with antioxidants that combat inflammation and oxidative stress. Cinnamon helps regulate blood sugar, while nutmeg adds warmth and a subtle earthiness that enhances the sweet potato’s natural goodness. Together, they make this pie both delicious and beneficial.
Calcium from Eggs
Each serving contains about 3% of your daily calcium thanks to the eggs used in both the filling and meringue. Calcium is crucial for bone health, muscle function, and nerve signaling—so you’re getting a hidden nutrient boost in what feels like pure indulgence.
The meringue powder (or fresh egg whites) ensures you’re maximizing this benefit without altering the texture.
Low-Cholesterol Indulgence
While traditional pies often rely on butter and cream, this recipe keeps cholesterol in check by using egg whites for the meringue and evaporated milk instead of heavy cream.
The filling remains rich and creamy, but with less than 100mg of cholesterol per slice—about half of what you’d find in a classic pumpkin pie. It’s a guilt-free way to enjoy a decadent dessert. 💛

Frequently asked questions
Can I make this sweet potato pie without a homemade crust?
Store-bought pie crust works perfectly—just choose a high-quality brand like Pillsbury and press it firmly into your 9-inch pie dish. Chill it for 30 minutes before baking to prevent shrinking. For extra flakiness, brush the bottom with a bit of melted butter before adding the filling.
Why does my meringue sometimes collapse or burn?
The key is baking at the right temperature and timing. Use 350°F for 10-12 minutes—no higher! Spread the meringue evenly and seal it to the crust edge to prevent burning. Let the pie cool completely on a wire rack before slicing, or the meringue may deflate. Humidity can also cause collapse, so bake on a dry day.
Can I use canned sweet potatoes instead of fresh?
Yes! Canned sweet potatoes work perfectly and save time. Drain and mash them until smooth, then proceed with the recipe. For extra creaminess, add 2 tablespoons of evaporated milk to the filling. Just avoid varieties with added sugar or salt, as they can alter the flavor balance.
How do I store leftovers to keep the meringue fresh?
Store the pie in an airtight container in the fridge for up to 3 days, but remove the meringue topping before storing to prevent sogginess. Reheat slices in the oven at 300°F for 5-10 minutes to restore the meringue’s texture. For longer storage, freeze the filling (without meringue) for up to 3 months—just add fresh meringue when ready to serve.
What’s the secret to getting that perfect golden crust?
Pre-bake your crust for 15 minutes with pie weights before adding the filling. This ensures a crisp base without burning. For extra shine, brush the baked crust with a light egg wash (1 egg yolk + 1 tablespoon water) before adding the filling. A 375°F oven temperature is ideal for even baking without browning too quickly.
