Gluten Free Sweet Potato Pie
This gluten free sweet potato pie is a Thanksgiving dessert made better-for-you.
Looking to enjoy a holiday classic without all the added sugar? Here’s a gluten free sweet potato pie that has a low carb crust and absolutely no added sugar. We use our sugar free flavoring syrup and our keto maple syrup to sweeten. We don’t use artificial sweeteners or added sugar, so this sweet potato pie will taste like the real deal. Warm, velvety, sweet potato filling in a crispy pie crust topped with mini marshmallows will please a crowd and your taste buds! You’ll love the natural sweetness of the sweet potato pie with a hint of maple and fall spices.
Making a keto friendly pie crust can be hard. Low carb flour like almond flour or coconut flour don’t behave exactly like wheat flour, so it can be frustrating for a first time baker. But, the good news is that this pie crust has a secret ingredient: lupin flour. Lupini flour is a new star on the low carb baking scene that enhances the texture of your bake. We use it in everything from cookies to cakes. In a gluten free pie crust, it crisps up the dough so perfectly that you’ll think it’s grandma’s pie crust recipe!
Sweet potato is a naturally gluten free food full of fiber, nutrients, and antioxidants. It’s a great option for those with celiac disease or are just watching their gluten intake. While other sweet potato pies are loaded with sugar, we use our sugar free syrups to enhance the natural flavor of sweet potato. Since maple is a great flavor to pair with this pie, we use our sugar free maple syrup to bring those fall vibes. None of our products use erythritol or maltitol, so there’s no bad aftertaste or side effects. If you make this healthy sweet potato pie for Thanksgiving, no one will guess it’s actually sugar free.
While traditional sweet potato pie does not have a marshmallow topping, we thought it would be fun to add our sugar free marshmallows to the top! We broil the marshmallows so that they get crispy and caramelized. It makes an eye-catching pie that your family will want a slice of.

Ingredients
Sweet Potato Pie Filling
- 3 medium sweet potatoes, baked, cooled, and peeled
- 1/4 cup sugar free vanilla coffee syrup
- 1/4 cup keto maple syrup
- 1/4 cup almond milk
- 1 egg + 1 egg yolk
- 1 tsp cinnamon
- 1/2 tsp nutmeg
Gluten Free Crust
- 1/4 cup butter, cold & cubed
- 1 1/2 cups almond flour
- 1/2 c Lupin flour
- 2 tbsp sugar free honey
- 1 egg white
- 1 cup sugar free mini marshmallows, for topping
Directions
Sweet Potato Pie Filling
Cook sweet potatoes - can air fry, bake, or boil. Once cooked, set aside to cool.
Add sweet potatoes to a food processor and blend until smooth. Add in eggs and mix until combined. Add in remaining ingredients and stir until smooth.
Gluten Free Crust
Preheat oven to 325°F. Add butter and flours to a bowl and use a pastry cutter or your fingers to mix together until crumbly. Add egg white and honey and keep mixing the dough until it comes together.
Put the dough between 2 sheets of parchment paper, and roll out into a large circle. Very carefully place crust over greased pie dish and press crust into pan and around edges. Poke holes in the bottom of crust with a fork.
Bake crust at 325°F for about 8 minutes, then remove and add filling. Smooth the top with a spatula.
Bake on 350°F for 35-40 minutes, until the edges on the pie are set. The center will still be slightly jiggly.
Place mini marshmallows on top in an even layer, then place in the oven on broil for 3-5 minutes just until the marshmallows start to get toasty. Be sure to keep a close eye on it, as they will toast quickly.
Leave on counter until fully cooled, about 3-4 hours. Then place in the refrigerator. When ready to serve, top with whipped cream if desired.
