I grew up eating pumpkin pie at Thanksgiving. And don't get me wrong, I adore the classics. Pumpkin pie, pecan pie... yep love 'em.
But this sweet potato pie has me swooning! And after doing a few recent recipe tests- my taste testers agreed. Sweet potato pie is truly superior. Well, at least this version.

📖Why This Recipe Works
Sweet potatoes are naturally sweeter than pumpkins. When making the perfect sweet potato pie you actually need to go light on sugar and no pumpkin pie spices.
Instead, the seasoning tends more toward ginger and we added a bit of maple syrup for richness.
Of course, it has the extra flaky crust thanks to my all-butter gluten-free crust recipe.
🧾Ingredient Notes
Sweet potato puree is the star here, and no you can't use canned puree. Unfortunately, it will be too watery. Fortunately, roasting the whole sweet potatoes is entirely hands-off!
You can substitute purple sweet potatoes, great for Halloween or Easter desserts.
You can use this recipe with a traditional pie crust or gluten-free pie crust. Premade, or my homemade GF pie crust recipe. Because I use this recipe for all my traditional pies I do not repeat it on every pie post.
Half and Half- The creamy part of the filling is half and half. You can substitute half milk and half heavy cream for the half and half.
Maple Syrup- For a fun twist try barrel-aged syrup.
Brown Sugar- You can use light or dark brown sugar. Or even brown coconut sugar. Just don't use white sugar in this recipe.
Seasonings- Ginger, nutmeg, cinnamon, and kosher salt.
You will also need eggs and vanilla extract.
Marshmallow Meringue Topping
If you want to make the meringue topping you will need 3 more eggs (whites only), a jar of marshmallow fluff or marshmallow cream, and sugar. The cream of tartar is optional but very helpful.
See the recipe card for exact quantities.
⏲️How to Make GF Sweet Potato Pie
The sweet potato filling is incredibly simple to make but first we need to prep our pie crust and bake the sweet potatoes.
Typically I prep the crust while the potatoes are roasting but for the sake of explaining the recipe we will deal with the pie crust in one swoop.
Step 1- Par-Bake the Pie Crust
Remove your pie crust from the plastic wrap and place it on a lightly floured surface. Use your rolling pin in a forward motion turning it 90 degrees to the right after each stroke.
I prefer to do this on a Silpat or pastry mat so I can simply flip the crust into the pie plate.
Press your pie crust into the pie pan and ensure there are no air bubbles. Trim the edges and fold them over. Flute the edges or crimp using a fork.
At this point you can chill the crust until the sweet potatoes are done roasting.
To par-bake the crust you need to dock the dough (i.e. poke the bottom of the pan with a fork) all over. Line with parchment paper and fill with pie weights or dried beans.
Bake at 425 F degrees for 12 to 15 minutes. The edge will begin to turn golden but the bottom will be fairly raw still.
Step 2- Make the Sweet Potato Puree
The sweet potatoes need to bake at 400 F degrees for at least 50 minutes. They are ready when they are fork tender. Allow them to cool until you can safely handle them.
Cut the sweet potatoes in half and scoop out the flesh. Measure out the quantity needed, save the rest for smoothies or a root vegetable puree.
The roasting of the sweet potatoes can be done 2 days in advance. Store in an airtight container in the fridge.
Step 3- Make the Filling
The easy part! Be sure to turn the oven temperature down at this point.
Combine the sweet potatoes with the remaining filling ingredients. Puree until smooth. You can do this with a hand mixer or a food processor.
Pour the filling into the par-baked crust.
Note that this recipe is for a 9-inch crust and my photos are of a 10-inch deep dish pie pan. I made a double batch of the filling and used two-thirds of it my regular pie and one-third for a smaller marshmallow topped pie.
Step 4- Bake
Sweet potato pie bakes low and slow at 350 F degrees. The pie is ready when the center is still slightly jiggly. This takes about 50 minutes if you properly cooked your oven after baking the crust.
If the edges of the pie begin to brown you can cover them with a cake shield.
Cool the pie on a rack in a cool space, but not in the refrigerator, for at least 2 hours and then move to the fridge and chill an additional 4 hours. The custard needs time to properly set.
Serve your pie with whipped cream or add the marshmallow meringue right before serving.
👩🏻🍳 Expert Tip
To get a smooth cut on your pie slices warm your knife under hot tap water. Dry with a towel and wipe on just a dab of olive oil. The heat will easily cut trough the pie and the oil will prevent the custard filling from sticking to the knife.
💭 Marshmallow Meringue Topping
I know traditional sweet potato pie doesn't have marshmallows but I could resist a fun twist for the most decadent holiday treat.
The topping is made by beating egg whites until stiff and glossy. Then slowly, and gently, mix it with the marshmallow fluff.
Spoon and swirl the meringue on the fully chilled pie. Bake for 10 minutes or until it was set.
🌡️Storage
Cover leftover pie with aluminum foil and refrigerate for 2 to 3 days. But who are you kidding? It isn't going to last that long.

💬Frequently Asked Questions
No, pumpkin pie relies on more spices and sugar to develop flavor. Thanks to the natural sweetness, sweet potato pie filling is lighter with more of ginger kick.
Always use fresh sweet potatoes for sweet potato pie. Canned puree will have too much water causing your pie crust to have a soggy bottom.

For the 1 ½ sweet potatoes: Is that the weight BEFORE or AFTER peeling? Thanks!
Jen Wooster says
Great question Monika! That is before peeling, so purchase weight. You will actually measure out sweet potato after cooking. Happy pie making!
