Maple Sweet Potato Pie with a Pecan Oat Crust
Maple sweet potato pie: roasted sweet potatoes, maple syrup, eggs, butter, cinnamon, nutmeg and ginger in a press-in pecan oat crust. About 15g of sugar a slice.

The short answer
Sweet potato pie is the dessert on every Southern holiday table, and this one keeps the silky spiced filling while trimming the sugar to about 15 grams a slice. Roasted sweet potatoes, maple syrup, eggs, butter and warm spices go into a press-in pecan oat crust. No rolling pin needed. It takes about 20 minutes of hands-on time.

The pie plate comes out and the whole table goes quiet. Of course, that is sweet potato pie. The only thing wrong with the usual version is the cup and a half of sugar poured over the sweetest vegetable in the store. So this one lets the sweet potato do the talking.
It’s one of the meals from our guide to how to eat clean without giving up the foods you grew up on, and it’s built the Clean Fit Fab way: real food, big flavor, and no seed oils.
Why this sweet potato pie belongs on a clean plate
- Roasting the sweet potatoes does the sweetening. Roasting instead of boiling concentrates the natural sugars, so you need far less added sweetener.
- Maple syrup replaces white and brown sugar. In fact, a third of a cup sweetens the whole pie.
- The crust is pecans, oats and butter. It presses into the pan in 5 minutes, and it brings fiber and healthy fat with it.
- Each slice has about 4 grams of fiber. Meanwhile, most dessert pies have close to zero.
Sweet potatoes are one of the richest food sources of vitamin A, with a medium baked one supplying more than a day’s worth, based on USDA data. The Harvard Nutrition Source has more on why this root earns a place on the plate, even in dessert.
The flavor: what makes it taste so good
A great sweet potato pie tastes like the potato, not like a sugar bomb. So this filling leans on cinnamon, freshly grated nutmeg, ginger, a little vanilla and a good pinch of salt. The salt makes the maple taste sweeter than it is. Then browned butter in the filling adds that nutty, toasty note you remember from grandma’s kitchen.
- Roasted, not boiled, sweet potatoes for deeper flavor and natural sweetness
- Browned butter for a toasty, caramel note
- Cinnamon, fresh nutmeg and ground ginger, the classic trio
- Pure maple syrup and vanilla
- Toasted pecans in the crust for crunch
What you need
Here’s a quick look at the ingredients. Exact amounts are in the recipe card below.
- Filling: sweet potatoes, butter, eggs, pure maple syrup, whole milk, vanilla extract, ground cinnamon, freshly grated nutmeg, ground ginger, sea salt
- Pecan oat crust: old-fashioned rolled oats, pecan halves, Medjool dates, sea salt, ground cinnamon, butter
- To serve: plain Greek yogurt, toasted pecans
Also, a note on fat: we cook with extra virgin olive oil, avocado oil, butter or ghee. They taste better, and they’re real food.
How to make sweet potato pie
First, roast the sweet potatoes until they collapse, then scoop and mash them smooth. Next, pulse oats, pecans, a date, salt and melted butter into a crumbly dough and press it into a pie plate. Then whisk the sweet potato with eggs, milk, browned butter, maple and spices. Pour it in and bake until the center barely jiggles. The full recipe card is below.

Heat the oven to 400 F. Prick the sweet potatoes, set them on a sheet pan and roast 50 to 60 minutes until they collapse when pressed. Cool, peel and mash until smooth. You need 2 cups. Lower the oven to 350 F.
Start 60 min timerPulse the oats, pecans, dates, salt and cinnamon in a food processor until it looks like coarse sand. Add the melted butter and pulse until it clumps. Press firmly into the bottom and up the sides of a 9-inch pie plate. Bake 10 minutes, then cool.
Start 10 min timerMelt the 4 tablespoons of butter in a small pan over medium heat and cook, swirling, 3 to 4 minutes until it foams, smells nutty and turns golden brown. Set aside.

Pour the filling into the crust. Bake 45 to 50 minutes, until the edges are set and the center wobbles slightly. Tent the crust with foil if it browns too fast.
Start 50 min timerCool on a rack at least 2 hours, then chill or serve at room temperature with the maple yogurt and toasted pecans.

Swaps and variations
- Use canned pumpkin or roasted butternut squash in place of the sweet potato for a different fall pie.
- Swap pecans for walnuts in the crust, or use all oats for a nut-free version.
- Whole milk, half-and-half or full-fat coconut milk all work in the filling.
- For a vegan version, use the cashew and coconut filling and the coconut oil crust (see the vegan switch on the card).
Make-ahead and storage tips
Cool the pie completely, then cover and refrigerate for up to 4 days. Also, it slices cleanest the next day. Freeze whole or in slices for 2 months and thaw overnight in the fridge.
Frequently asked questions
Is sweet potato pie healthier than pumpkin pie?
They are close. Sweet potato brings a little more fiber and natural sweetness, which lets you cut the added sugar further. The crust and the sugar matter more than the vegetable.
How much sugar is in this sweet potato pie?
About 15 grams a slice, with roughly 8 of those from the maple syrup and the rest from the sweet potatoes themselves. A traditional slice often has 30 grams or more.
Can I make the pie ahead?
Yes. Bake it a day ahead and chill it. The flavor deepens, and the slices come out cleaner.
Why did my filling crack?
It was overbaked. Pull the pie when the center still wobbles slightly, like set gelatin. It finishes setting as it cools.
