intro

A velvety, warmly spiced Southern American classic with creamy roasted sweet potato filling in a flaky buttery crust, a beloved holiday table staple.

Ingredients

Orange-fleshed sweet potato 450 grams (about 2 medium)
Unbaked 9-inch all-butter pie crust 230 grams (1 single crust)
Unsalted butter, melted 113 grams (1/2 cup / 1 stick)
Granulated white sugar 100 grams (1/2 cup)
Packed light brown sugar 100 grams (1/2 cup tightly packed)
Large eggs, lightly beaten 2 units (100 grams total, out of shell)
Evaporated milk 120 ml (1/2 cup)
Ground cinnamon 2 grams (1 teaspoon)
Freshly grated nutmeg 0.5 grams (1/4 teaspoon)
Pure vanilla extract 5 ml (1 teaspoon)
Fine table salt 3 grams (1/2 teaspoon)

Steps

1

Roast the sweet potatoes

Preheat your oven to 200°C (400°F). Scrub sweet potatoes clean, prick their skins 4-5 times with a fork, and place directly on the middle oven rack. Roast for 45-50 minutes until flesh is fully fork-tender, then remove and let cool for 15 minutes until safe to handle.

Step 1
step1:Roast the sweet potatoes
2

Prep the pie crust

While sweet potatoes roast and cool, unroll the 9-inch pie crust and press it firmly into a 23cm (9-inch) glass pie dish, crimping the edges decoratively with your fingertips. Prick the crust bottom 8-10 times with a fork, then chill in the refrigerator for 10 minutes to prevent shrinkage during baking.

3

Make the filling base

Peel the cooled roasted sweet potatoes, discard skins, and scoop 400 grams of soft flesh into a large mixing bowl. Add the melted unsalted butter, then mash with a potato masher for 2 minutes until completely smooth with no stringy lumps remaining.

4

Combine filling ingredients

Add granulated sugar, packed light brown sugar, beaten eggs, evaporated milk, ground cinnamon, grated nutmeg, vanilla extract, and salt to the mashed sweet potato. Whisk on low speed with an electric hand mixer for 1 minute until fully uniform, taking care not to overmix, which can cause surface cracking as the pie bakes.

5

Bake the assembled pie

Pour the smooth filling into the chilled pie crust, spreading it evenly with a silicone spatula. Bake at 175°C (350°F) on the middle oven rack for 50-55 minutes, until the edges are fully set and the central 5cm (2-inch) area jiggles slightly like soft Jell-O when the dish is gently nudged.

Step 5
step5:Bake the assembled pie
6

Cool and set the pie

Remove the baked pie from the oven and transfer it to a wire cooling rack. Let it cool completely at room temperature for 2 hours, then chill in the refrigerator for a minimum of 1 hour before slicing to allow the custard filling to set firmly.

Tips

1.Never boil sweet potatoes for the filling—dry-heat roasting concentrates their natural sweetness and prevents excess water that leads to a soggy crust.
2.If the pie crust edges turn deep golden brown 20 minutes before the bake time ends, wrap them in a 5cm (2-inch) wide strip of aluminum foil to shield them from burning.
3.Resist slicing the pie warm; cutting into it before it fully cools and chills will cause the soft custard filling to run and lose its clean, firm shape.

Sweet Potato Pie:Frequently Asked Questions

1.Do I really need to roast my sweet potatoes, or can I boil them instead for this pie?
Roasting is highly recommended for the richest, deepest sweet potato flavor and velvety, non-watery filling—boiling can make potatoes absorb excess water that leads to a runny pie. If you’re short on time and need to boil, peel and cube potatoes first, drain very thoroughly, and pat dry with paper towels before mashing to cut down on extra moisture.
2.Is it okay to use a store-bought pie crust instead of making an all-butter crust from scratch?
Absolutely! A high-quality store-bought refrigerated all-butter pie crust works perfectly for this recipe and cuts down on prep time significantly. Let it sit at room temperature for 10–15 minutes before fitting it into your pie plate, crimp the edges, and blind bake for 10 minutes first if you find store-bought crusts turn soggy with wet, custardy fillings.
3.How do I get a perfectly smooth, lump-free sweet potato pie filling?
Lumpy filling almost always comes from under-mashed sweet potatoes that still have tough, stringy fibers left. For a perfectly silky texture, pass your mashed roasted sweet potato through a fine-mesh sieve before mixing in butter, sugars, and spices. Use an electric mixer on low speed to combine ingredients, but avoid overmixing, which can cause the filling to crack as it bakes.
4.How do I prevent a soggy bottom crust on my sweet potato pie?
The easiest fix for a soggy bottom crust is a quick 10-minute blind bake before adding filling: line the crust with parchment, fill with pie weights or dried beans, bake at 375°F, then remove weights and cool slightly. For extra insurance, brush the warm pre-baked crust with a thin layer of beaten egg white to create a moisture barrier between the crust and the filling.
5.How long do I need to let the pie cool before I can slice and serve it?
Sweet potato pie is a custard-based pie, so it needs time to set fully after baking to get clean, neat slices. Let it cool completely on a wire rack for at least 2 hours at room temperature, then chill it in the fridge for 1 more hour for the best texture. If you serve it too warm, the filling will be soft, runny, and won’t hold its shape when sliced.
6.Can I make this sweet potato pie ahead of time for holiday gatherings?
Absolutely—this pie actually tastes better when made a day ahead, as the warm spices have time to meld and the filling sets to its ideal velvety consistency. Once it cools completely, wrap it tightly in plastic wrap and store it in the refrigerator for up to 3 days. Let it sit at room temperature for 20 minutes before serving to take the chill off.
7.Why did the top of my pie crack while baking, and can I fix it?
Cracking usually happens from overbaking the filling, using too high an oven temperature, or overmixing the filling which traps extra air that expands and then deflates as it cools. Small cracks are easy to hide with a dusting of powdered sugar, a dollop of freshly whipped cream, or a drizzle of salted caramel right before serving, so they don’t have to ruin your pie.

OMG this sweet potato pie was the star of our Sunday family dinner! I added a tiny extra dash of cinnamon and nutmeg like my grandma used to, and the texture was so creamy, no weird stringy bits at all. My picky 7 year old asked for a second slice before he even finished his first! 10/10 will be making this for Thanksgiving for sure.

Wait did you boil or roast the sweet potatoes first? I always end up with watery pie when I boil them and I’m trying to avoid that this year!

So glad your family loved it! Pro tip: roast the sweet potatoes instead of boiling them for a deeper, sweeter flavor and no watery texture — that’s the trick we use in this recipe to keep the filling perfectly thick!

Took this to my office potluck last week and folks were coming up to me asking for the recipe for 3 days straight! I was worried the cook time was too long for a weeknight prep, but I roasted the sweet potatoes the night before and assembly was a total breeze. Only note: I used a store-bought deep dish crust because I’m terrible at making pastry from scratch, and it still turned out chef’s kiss.

Love the prep hack of roasting sweet potatoes ahead! No shame in store-bought crust — this recipe works perfectly with it, I’m so glad it was a potluck hit!

I made a couple swaps to make this dairy free — used coconut cream instead of evaporated milk and vegan butter — and it still turned out SO good! The spice balance is perfect, not too cloyingly sweet like the store-bought pies I’ve tried before. Will absolutely be adding this to my holiday rotation.

Uh oh, I think I messed this up? My filling cracked really bad on top after baking, and it was a little jiggly in the very center when I pulled it out at the 1 hour 50 mark. Did I do something wrong? Flavor was still great though, my roommate ate half the pie in one sitting lol.

1 hour ago

The jiggly center is totally normal! It sets as it cools, I promise. The cracking usually happens if the oven temp is a little too high or if you overbake the edges a bit — I cover my crust edge with foil halfway through to prevent that now!

30 minutes ago

@FirstTimeBakerJake @BakeWizMia is exactly right! That slight center jiggle means it’s done — residual heat will finish setting it as it cools completely (we’re talking 2+ hours on the counter, don’t rush it in the fridge!). If cracking bothers you, you can always top it with a little whipped cream to hide it, no one will ever know 😉

Game changer for my Sunday meal prep! I made two of these over the weekend, sliced them up, and kept individual slices in the fridge for quick sweet treats all week. They hold up so much better than I thought they would, even after 5 days chilled. So much better than grabbing a candy bar from the vending machine at work.

Wait do you freeze any of the slices? I’m wondering if these freeze well for longer storage, I’d love to stock up for next month!

I’ve been making my mom’s sweet potato pie for 20 years and decided to give this recipe a test run before our church Thanksgiving dinner. Let me tell you, this one might dethrone mom’s (don’t tell her I said that!!!) The balance of brown sugar and vanilla is perfect, not overpowering, and the crust came out flaky every single time. Even my aunt who swears she doesn’t like sweet potato pie had a slice.

yesterday

Help! I followed the recipe exactly but my filling came out really lumpy? I mashed the sweet potatoes with a hand mixer like it said, but there are still little chunks all through it. Did I not cook the sweet potatoes long enough? It tastes fine but the texture is throwing me off.

yesterday

I had this happen the first time too! I ran my filling through a fine mesh sieve after mixing, and it came out perfectly silky, zero lumps. Total game changer, takes 2 extra minutes max.

30 minutes ago

@HolidayBakeFail Great tip from @SmoothPieStan! If you don’t have a sieve, you can also blend the filling in a regular blender or food processor for 30 seconds to get rid of lumps. Next time, make sure your sweet potatoes are fork-tender all the way through before mashing — that helps too!

This pie is SO good I could eat the filling straight out of the bowl with a spoon! I topped mine with a dollop of homemade bourbon whipped cream and a sprinkle of candied pecans, and my guests at Friendsgiving went absolutely wild for it. 10/10, no notes, this is my new go-to sweet potato pie recipe forever.

6 days ago

Bourbon whipped cream and candied pecans sound like the perfect upgrade! We’re so glad this was a Friendsgiving hit, that topping combo sounds good enough to eat on its own 😂

Made this with a gluten free almond flour crust for my sister who has celiac, and it was incredible! I was worried the filling would be too dense, but it was light and perfectly spiced, and you couldn’t even tell the crust was gluten free. She said it’s the best sweet potato pie she’s had since going gluten free 8 years ago.

2 days ago

Oh that’s such a good idea! Did you pre-bake the almond flour crust before adding the filling? I’ve had issues with soggy gluten free crusts in the past and don’t want to mess this up.

Made this for my dorm floor potluck and people were shocked I didn’t buy it from a bakery! I don’t have a hand mixer so I just mashed the sweet potatoes really well with a fork, and it still turned out great. Super straightforward recipe even for someone who barely knows how to turn on an oven tbh.

This makes us so happy! You don’t need fancy equipment to make great pie — a fork and a little elbow grease works perfectly. So glad your floor loved it!

My daughter begged me to make sweet potato pie for her birthday instead of cake this year, and this recipe did not disappoint! I was nervous because I’ve only ever made apple pie before, but the instructions were so clear and easy to follow. She said it was better than the pie we get at our favorite local diner, which is the highest compliment possible in our house.

I’ve tried so many sweet potato pie recipes over the years, and this one is easily top tier. It tastes just like the ones my mother used to make when I was a kid growing up down south. I brought a slice to my next door neighbor and he brought me a jar of his homemade wildflower honey as a thank you, that’s how good it is. Will be making this for every holiday and potluck from now on, no more searching for the perfect recipe!
