Sweet Potato Pie With Agave Recipe: Spiced Custard Magic Without Refined Sugar

This vegan sweet potato pie with agave delivers all the warmth of a classic holiday dessert without refined sugar or dairy. The secret lies in roasting sweet potatoes until tender, then blending them with agave for natural sweetness and a smooth, velvety custard.

Spices like cinnamon and nutmeg create that signature cozy flavor, while flaxseed or aquafaba binds everything together—no eggs needed.

The crust is where this pie truly shines, using almond flour or coconut oil for a sturdy, buttery base that holds up to the creamy filling. Baking at 350°F ensures a golden crust and perfectly set custard, with just a hint of caramelization on top.

The agave not only sweetens but also adds depth, balancing the earthy sweetness of the potatoes.

What you’ll end up with is a pie that’s rich, spiced, and impossibly smooth—every slice offering a perfect blend of texture and flavor. The crust stays crisp, the filling is silky, and the agave gives it that natural sweetness that lingers without overpowering.

This is comfort food at its finest, made even better by being completely plant-based.

Perfect for holiday gatherings or a cozy dessert night, this pie proves you don’t need butter, eggs, or refined sugar to create something extraordinary. The agave makes it a healthier choice without sacrificing taste, and the vegan substitutions ensure everyone at the table can enjoy a slice. Let’s get baking!

Ingredients for sweet potato pie with agave

Sweet potatoes, coconut milk, and agave create this velvety vegan pie with holiday warmth.

The sweet potatoes need to be roasted until they're fork-tender—about 45 minutes at 400°F. I always grab the organic orange-fleshed kind from the produce section, not the pre-packaged bags. The agave should be pure, light-colored—Wholesome! or Madhava are my go-tos. For the coconut milk, full-fat canned is non-negotiable—the lighter versions won't give you that rich custard texture. The almond flour? Bob's Red Mill is my favorite brand—it's finely ground and stays fresh longer than the store-brand stuff.

No agave? Date syrup or maple syrup works in a pinch, but the flavor profile changes slightly. The flax eggs can be swapped for chia eggs (1 tbsp chia seeds + 3 tbsp water) if you're out of flax. For a nut-free option, use oat flour instead of almond flour—just add 1 tbsp coconut oil extra to bind. The spices are where this pie gets its magic, so don't skimp. Penzeys has the best pre-ground spices if you want to splurge, but the regular grocery store stuff works fine if it's fresh. For the crust, if you can't find almond flour, blend whole almonds in a food processor—it takes 5 minutes and makes a huge difference.

This pie tastes even better the next day—the flavors meld perfectly after resting overnight. Store leftovers in an airtight container in the fridge for up to 5 days. For freezing, slice it first and freeze on a tray before transferring to a bag—prevents soggy crust. I usually make two pies at a time and freeze one for later. The crust stays crisp if you reheat slices in the oven at 350°F for 5-10 minutes—just enough to warm through without drying out.

Step-by-step instructions for sweet potato pie with agave

Here's how to create a velvety, naturally sweetened pie that's rich, spiced, and perfect every time.

Preheat your oven to 375°F. Peel the 3 lbs sweet potatoes and cut them into 1-inch chunks. Place them on a parchment-lined baking sheet and roast for 45-50 minutes, stirring once halfway through, until they're fork-tender and golden. You'll know they're done when they collapse easily under gentle pressure.

Transfer the roasted sweet potatoes to a large mixing bowl and let them cool slightly. Once cool enough to handle, mash them with a potato masher or fork until completely smooth. This step is crucial—any lumps will make your pie filling grainy. I like to press the potatoes through a fine-mesh sieve for extra-smooth results.

In a small bowl, whisk together the 3 tbsp ground flaxseed with 9 tbsp water. Let this mixture sit for 5 minutes to thicken into flax eggs—this will be your egg substitute for binding. Meanwhile, in your mixing bowl with the mashed sweet potatoes, add the 0.75 cup agave nectar, 1 can full-fat coconut milk, 0.25 cup maple syrup, 1 tbsp vanilla extract, 2 tbsp ground cinnamon, 1.5 tsp ground nutmeg, 1 tsp ground ginger, and 0.5 tsp salt.

Whisk everything together until fully combined and smooth. The mixture should be thick but pourable, like a rich pudding. Taste and adjust the sweetness if needed—you can add a bit more agave or maple syrup if it tastes too tart. This is where the natural sweetness of the agave shines, giving you that perfect balance of spice and sweetness without refined sugar.

In a separate bowl, mix the 2 cups almond flour with the 0.5 cup melted coconut oil. Stir until it forms a crumbly dough. If it's too dry, add 1-2 tablespoons of water to help it come together. Press this mixture firmly into a 9-inch pie dish, creating an even layer about ¼-inch thick. Use the back of a spoon to smooth it out and create a slight rim around the edges.

Bake the crust in a 350°F oven for 12-15 minutes until it's lightly golden and firm to the touch. Let it cool slightly while you prepare the filling. The crust should hold its shape when you gently press it—if it crumbles, press it back into place and bake for another 2-3 minutes. This crust is the foundation of your pie, so taking the time to get it right makes all the difference.

Pour the sweet potato filling into the prepared crust, spreading it evenly. Gently tap the pie dish on the counter to remove any air bubbles. In a small bowl, whisk the 0.25 cup aquafaba until it forms stiff peaks—this will help create a lighter texture in your pie. Fold the aquafaba into the filling until just combined.

Bake the pie in the 350°F oven for 45-50 minutes, until the center is just set and a toothpick inserted comes out clean. The edges should be golden, and the filling should look slightly puffed. If the top browns too quickly, tent it loosely with aluminum foil. Let the pie cool completely before slicing—this allows the flavors to meld and the texture to set properly.

Once the pie is fully cooled, cover it with plastic wrap and refrigerate for at least 4 hours, or overnight. This chilling step is essential—it allows the pie to firm up beautifully and intensifies the flavors. When you're ready to serve, let it sit at room temperature for 10-15 minutes so the slices come out cleanly.

Slice into wedges and serve with a dollop of coconut whipped cream or a scoop of vanilla bean ice cream. Each bite should be rich, spiced, and perfectly balanced—no artificial aftertaste, just pure, naturally sweetened sweet potato goodness. The crust should be lightly crisp, and the filling should be velvety smooth with just the right amount of spice. Enjoy your creation!
