This silky sweet potato pie roasts the sweet potatoes instead of boiling them for concentrated flavor, then pulses them in a food processor to eliminate stringy fibers before gently whisking in eggs, evaporated milk, sugar, and warm spices. Total time runs about 4 hours 35 minutes including cooling, but most of that is hands-off roasting and chilling.
I am going to tell you how to make a silky and delicious sweet potato pie. Just like pumpkin pie, sweet potato pie is a silky and amazing flavored custard. Milk and eggs stabilize it, and we add sugar and spices for incredible flavor. It is actually super, super easy.
You should never be intimidated by a pie. The problems usually come from a few common mistakes like overbaking your pie, dealing with stringy sweet potatoes, or ending up with a soggy crust. Today, I am going to tell you how all of these things can be very easily avoided with just a few simple steps. Let us get started.

Why You Will Love This Silky Sweet Potato Pie
I absolutely love this pie, and I know you will too. Here is why it is going to be a new favorite at your holiday table:
- Zero Stringy Bits: One of people’s main gripes with sweet potatoes is that they can be fibrous. We completely fix that by pulsing the roasted potatoes in a food processor, giving you a silky and wonderful mouthfeel.
- Concentrated Flavor: We roast sweet potatoes instead of boiling them. Boiling gives you a soggy and diluted mess, but roasting concentrates the flavor and evaporates excess water.
- Warm and Cozy Spices: With a perfect blend of cinnamon, ginger for a little bite, and freshly grated nutmeg, the flavor profile is unbeatable.
If pie bars are more your speed for the holiday dessert table, my The Ultimate Pecan Pie Bars deliver that same warm, spiced holiday flavor in an easier-to-serve form.

Let Us Get Baking
1. Prepping Your Sweet Potatoes: Do NOT Boil Them
First off, you want to roast those sweet potatoes. Pierce them all over with a fork and place them onto a foil lined baking sheet. Preheat your oven to 375°F and bake for about 1 hour, or until very tender.
Whatever you do, do not boil your sweet potatoes. Baking them will concentrate the flavor, get rid of a little bit of the water, and give you that wonderful creamy filling. Once they are screaming hot and tender, set them aside for about 30 minutes to cool so you can peel them like magic.
2. The Crust Situation
You have two choices here. You can use a store bought frozen crust, or a homemade butter crust that you roll, fold, crimp, and freeze yourself. I love the flavor of a butter crust. It is just unbeatable for me and bakes up so crispy.
If you are using a homemade crust, you are going to blind bake it at 425°F so it does not get soggy. Place parchment paper into the frozen crust, then line with tripled up tin foil. Fill with ceramic baking weights or dried beans, pressing the foil right against the sides so the crust will not slip down. After 20 minutes, your crust will have a nice head start. Remove the foil and weights, set the crust aside, and remember to drop your oven down to 400°F as soon as the crust comes out.
Note that if you use a store bought frozen crust, skip the blind baking, or the edges will burn. Simply preheat your oven directly to 400°F.
3. Creating the Silky Smooth Puree
Peel the cooled sweet potatoes. The skin should slip right off. Give them the barest of chops, removing any scorched bits, and plop them into a food processor. Pulse this up until completely smooth and creamy to eliminate any stringy fibers. Measure out about 2 and 1/2 cups of the puree and transfer your beautiful and smooth sweet potato puree into a big mixing bowl.
If you’re comparing this to a pumpkin-based bake, my Spiced Pumpkin Bread uses a similar warm spice blend if you want to put the two side by side on your holiday table.
4. Mix the Filling
To the sweet potato puree, we will add our granulated sugar, room temperature eggs, evaporated milk, vanilla, cinnamon, ginger, nutmeg, and a pinch of salt. Sweet potatoes are denser and have more structure than pumpkin puree, so they only need two eggs to stabilize the custard.
Say goodbye to your food processor and grab a whisk. Use a spatula to gently fold the ingredients together first, then use your whisk. Whisk nice and slow until the mixture is completely smooth and lump free. Do not mix the whole filling in the food processor or whisk vigorously because that pumps tons of air into the mixture. Those air bubbles expand when it bakes, causing cracking and a less creamy texture. We just want to fold our ingredients together gently until smooth.
5. Bake
Pour that gorgeous filling into your prepared pie crust. Give the pie a little shimmy and swirl the top with your spatula to smooth it out. In it goes. Bake at 400°F for 15 minutes. Then, reduce the oven temperature to 350°F and bake for an additional 40 minutes, or until the edges are puffed up with just a little wobble in the center.
6. Cool and Serve
Allow the pie to cool completely to room temperature so the custard sets. Once baked and cooled, slice, dollop with whipped cream, and you are ready to enjoy.
What to Serve With This
- A dollop of fresh whipped cream is the classic finish
- Pair it with my Caramel Apple Galette if you want two different pie styles on your holiday dessert table
- A warm drizzle of caramel sauce adds an extra layer of richness for special occasions

FAQs
Should I boil or roast sweet potatoes for pie?
Roast them. Whatever you do, do not boil your sweet potatoes. Boiling them adds excess water and leaves you with a soggy and diluted mess. Roasting them at 375°F concentrates their natural sugars, cooks off extra moisture, and gives you a much richer and creamier pie filling.
How do I keep my sweet potato pie from being stringy?
Sweet potatoes are naturally fibrous, which is why people sometimes end up with stringy pies. The secret is to pulse your roasted and peeled sweet potatoes in a food processor before mixing your filling. It chops up all those fibers and guarantees a silky and wonderful mouthfeel.
Why did my sweet potato pie crack?
Cracks usually happen for two reasons. Those are overbaking or too much air in the batter. When you mix your filling, whisk it nice and slow. If you use a blender or whisk vigorously, you pump tons of air into the filling. Those air bubbles expand in the oven, causing the pie to puff up and crack as it cools.
Do I really need to blind bake the pie crust?
If you are using a homemade butter crust, yes. You want to blind bake it at 425°F with pie weights so the bottom gets a head start and stays perfectly crisp instead of turning soggy. However, if you are using a store bought frozen crust, skip the blind baking, or the edges will burn.
How do I know when my sweet potato pie is done?
Your pie is ready to come out of the oven when the edges are beautifully puffed up and the very center still has just a little wobble to it. It will continue to set up as it cools to room temperature, giving you that perfect and creamy custard texture.
How is sweet potato pie different from pumpkin pie?
They are close cousins but not the same. Sweet potato pie uses roasted sweet potato puree, which is naturally denser and sweeter, so it needs fewer eggs to set (just 2 here) and has a slightly richer, more caramelized flavor. Pumpkin pie uses canned or fresh pumpkin puree, which is wetter and milder, so it typically needs a bit more egg and spice to achieve the same structure and flavor depth.
Can I make this with bourbon or rum instead of vanilla?
Yes, swapping the vanilla extract for 2 teaspoons of dark rum or bourbon adds a lovely depth of flavor for a festive twist. Keep in mind that baking cooks off some, but not all, of the alcohol content, so if you are serving this to children or anyone avoiding alcohol, it is best to stick with the vanilla extract instead.
Can I use brown sugar instead of granulated sugar?
Absolutely. Brown sugar swaps in at a 1:1 ratio and adds a deeper, more molasses-forward sweetness that pairs beautifully with the cinnamon, ginger, and nutmeg in this recipe.
Do I need a thermometer to check doneness?
Not necessarily, the puffed-edges-with-a-slight-wobble method works well and is what most bakers rely on. But if you want a more precise check, an instant-read thermometer inserted into the center of the custard should read around 175 to 180°F when it is fully set.

Ingredients
- Equipment Needed:
Baking sheet
Aluminum foil
Food processor
Ceramic pie dish (9-inch)
Parchment paper
Ceramic baking weights (or dried beans)
Whisk
- Ingredients:
2 lbs sweet potatoes (about 900g, yields approximately 2 1/2 cups / 560g puree)
1 (9-inch) pie crust, homemade butter crust or store-bought frozen
3/4 cup (150g) granulated sugar, or brown sugar
2 large eggs, room temperature
1 cup (240ml) evaporated milk, or whole milk
2 tsp vanilla extract, or dark rum or bourbon
3/4 tsp ground cinnamon
1 tsp ground ginger
1/4 tsp ground nutmeg, freshly grated preferred
1 pinch salt, optional
Whipped cream, for topping
Directions
- Preheat oven to 375°F. Pierce sweet potatoes with a fork and place on a foil-lined baking sheet. Bake for 1 hour or until very tender. Let cool for 30 minutes.
- If using a homemade crust, preheat oven to 425°F. Line the frozen crust with parchment paper and tripled-up foil. Fill with pie weights and press the foil against the sides. Blind bake for 20 minutes. Remove weights and foil, set crust aside, and reduce oven temperature to 400°F. If using a store-bought crust, skip blind baking and simply preheat oven to 400°F.
- Peel the cooled sweet potatoes, roughly chop, and place in a food processor. Pulse until perfectly smooth and creamy. Transfer 2 1/2 cups of the puree to a large mixing bowl.
- Add the sugar, eggs, evaporated milk, vanilla, cinnamon, ginger, nutmeg, and salt to the puree.
- Fold the ingredients together with a spatula, then switch to a whisk. Whisk slowly until perfectly smooth. Do not over-mix or whisk rapidly.
- Pour the filling into the crust. Give it a gentle shimmy to level it out.
- Bake at 400°F for 15 minutes.
- Reduce oven temperature to 350°F and bake for another 40 minutes, or until the pie is puffed with a slight wobble in the center.
- Cool to room temperature before serving. Top with whipped cream.
Notes
- Roast, Don’t Boil: Whatever you do, do not boil your sweet potatoes. That will give you a soggy, diluted mess. Roasting concentrates the flavor and cooks out the excess water.
- Whisk Slowly: Be careful not to whip air into your filling. Those air bubbles will expand when it bakes, puffing things up and causing cracks. Slow, gentle whisking is key.
- Spices: I always have a rasp handy to grate my own nutmeg, it makes a huge difference. But powdered nutmeg works wonderfully, too.
- Make It Festive: Want a fun holiday twist? Swap out the vanilla extract for 2 teaspoons of dark rum or bourbon. Baking cooks off some, but not all, of the alcohol, so skip this swap if serving to children or guests avoiding alcohol.
- Doneness Check: The edges should be puffed with a slight wobble in the center. For a more precise check, a thermometer inserted into the center should read about 175 to 180°F.
- Allergen Note: Contains eggs, dairy (evaporated milk), and gluten (pie crust).
