The sweet potatoes and yams are the heart of this pie. Orange-fleshed varieties work best—they're naturally sweeter and creamier. I always grab mine from the produce section at Whole Foods or my local farmers market in season. Look for firm, heavy yams with smooth skin; sweet potatoes should feel dense and free of soft spots. Peeled and cubed, they roast until tender and caramelized, which is what gives this pie its signature texture. Pro tip: roast them at 400°F for about 25 minutes to concentrate their natural sugars without drying out.
No heavy whipping cream? Full-fat coconut milk works in a pinch, though the flavor will differ slightly. The spices are non-negotiable—freshly ground cinnamon and nutmeg make all the difference. If you're missing one, pumpkin pie spice can substitute with a pinch of extra cinnamon. For the vanilla, imitation extract—splurge on the good stuff. The evaporated milk adds richness without thinning the filling. If you're out, whole milk plus a splash of cornstarch (1 tsp) thickened on the stove will do the trick.
This pie reheats beautifully—just warm slices in the oven for 5-10 minutes until the edges are golden. Store leftovers covered at room temperature for up to 2 days or refrigerate for 4 daysup to 3 months—just thaw overnight in the fridge before baking.
Why You'll Love This Recipe
- No Bake, No Stress: I’ll admit, I used to avoid pies—until I realized this one just needs boiling and blending. Toss those yams and sweet potatoes into boiling water for 15 minutes, then puree with the eggs and cream. The crust? Optional. The mess? Minimal.
- Creamy Without Guilt: That velvety texture comes from the heavy whipping cream, but honestly, it’s the sugar that makes it dangerously good. The yams add natural sweetness, so you can cut back on sugar if you want—though I’ve never met anyone who actually does. It’s like dessert that doesn’t feel like cheating.
- Holiday or Weeknight Win: I’ve served this at Thanksgiving when I forgot to make pie and as a midnight snack when my roommate craved something sweet. The eggs and cream make it rich enough for company, but the simplicity keeps it from feeling like a chore. (Yes, even on a Tuesday night.)
- Leftovers That Last: Between us, I’ve reheated slices of this pie for days—it actually tastes better the second time. The sugar and cream create a caramelized crust when reheated, and it’s still moist inside. Plus, the yams keep it from drying out like regular sweet potato pie. Budget-friendly? Absolutely. Waste-free? Even better.
Step-by-step instructions for sweet potato pie with yams
Here's how to create a velvety, spiced filling that transforms humble sweet potatoes and yams into a dessert masterpiece.
Cook the Sweet Potatoes and Yams Until Tender
Preheat your oven to 375°F. In a large baking dish, combine the 2 lbs sweet potatoes and 2 lbs yams with ½ cup water. Cover tightly with foil and bake for 45-50 minutes until a fork slides in easily with minimal resistance. You want them soft enough to mash completely but not falling apart.
Here's the thing—don't skip the water. It prevents the vegetables from drying out in the oven. When they're done, let them cool slightly before handling. The residual heat will make them easier to peel and mash. I like to scoop them out directly from the skin while they're still warm, using a large spoon to avoid peeling each piece individually.
Make the Spiced Filling Mixture
While the vegetables are cooling, melt the ½ cup unsalted butter in a small saucepan over low heat until completely liquid. In a large mixing bowl, combine the mashed sweet potatoes and yams (about 4 cups total) with the melted butter, 1.5 cups granulated sugar, 2 tbsp ground cinnamon, 1 tsp ground nutmeg, 1 tsp ground ginger, ½ tsp salt, and 1 tbsp pure vanilla extract. Mix until completely smooth and well combined.
This is where the magic happens—the spices need to be worked into the warm mixture so they fully dissolve and infuse. I use a wooden spoon to press down on any stubborn dry spots. The mixture should be thick but pourable, like a rich pudding. If it's too thick, add 1-2 tablespoons of warm water to reach the perfect consistency.
Prepare the Egg Cream Mixture
In a separate bowl, whisk together the 4 room temperature eggs, 1 cup heavy whipping cream, and ½ cup evaporated milk until smooth and frothy. This step is crucial—room temperature eggs blend better and prevent curdling in the oven. Gradually pour this mixture into the spiced sweet potato mixture while whisking constantly to combine thoroughly.
Here's what I do next: I pour the egg mixture in a slow, steady stream while whisking vigorously. This prevents lumps from forming and ensures the eggs are fully incorporated. The batter should be thick but still able to coat the back of a spoon. If it's too thin, add 1-2 tablespoons of flour (though we're not using flour in this recipe, I've found this works in a pinch).
Assemble and Bake the Pie
Roll out the pre-made pie crust and fit it into a 9-inch pie dish, pressing gently to form the sides. Pour the filling mixture into the crust, spreading it evenly. Fold any overhanging crust edges under and crimp decoratively. Cut a few small slits in the top crust to allow steam to escape during baking.
Bake at 350°F for 50-55 minutes until the filling is set but still slightly jiggly in the center (it will firm up as it cools). The edges should be golden brown, and the top should have a beautiful caramelized sheen. To test doneness, gently shake the pie—if it doesn't jiggle much, it's ready. Let it cool completely before slicing, at least 2 hours, to allow the filling to set properly.
Pro Tips For Making Sweet Potato Pie Recipe With Yams
- Boil Until Fork-Tender: Sweet potatoes and yams should collapse like butter when pierced—no half-chewed resistance. I learned this the hard way after serving a pie with slightly firm centers that tasted undercooked. Drain them thoroughly afterward, or your filling will turn into soup.
- Peel While Warm: Hot peels slide off like magic—no peeling raw tubers and ending up with bloody knuckles. Run them under cold water after peeling to stop the cooking, but skip this step and you’ll waste time scrubbing stubborn skin later.
- Whip Cream Last: Add the heavy cream after baking, then swirl it in gently. This keeps the custard silky and prevents a watery texture from overmixing. (Yes, even if you’re impatient like me—trust the process.)
- Use Molasses, Not Just Sugar: Swap 1-2 tablespoons of sugar for dark molasses—it deepens the flavor without overpowering. My grandmother swore by this, and she was right: the pie tastes richer without needing extra sweetness. (Start with less; you can always add more.)
Troubleshooting this recipe
Filling Too Thin?
If your filling looks too runny before baking, don’t panic—this is fixable! The most common cause is over-mashing the sweet potatoes and yams. I’ve found that adding 1 tablespoon of cornstarch mixed with 1 tablespoon cold water thickens the filling beautifully.
Stir it in gently until fully dissolved, then proceed with assembly. Another trick? Chill the filling for 30 minutes before pouring it into the crust—this helps it set up better during baking. 💡
Soggy Bottom Syndrome
The dreaded soggy bottom happens when moisture gets trapped between the filling and crust. To prevent it, always pre-bake your pie crust for 8-10 minutes at 375°F before adding the filling. This creates a sturdy base that won’t absorb excess liquid.
I also recommend brushing the crust with a thin layer of egg wash (1 egg beaten with 1 tablespoon water) before adding the filling—it adds a protective barrier. If you’re using a store-bought crust, check the package for pre-baking instructions.
Filling Not Setting Properly
If your pie’s filling stays too soft or watery after baking, it’s likely undercooked or the eggs weren’t fully incorporated. First, ensure your oven temperature is accurate—use an oven thermometer to confirm it’s hitting 350°F. Another common issue is eggs that were too cold when mixed.
Next time, let your eggs sit at room temperature for 30 minutes before whisking. For extra insurance, bake the pie for 5-10 minutes longer until the center is just set (it’ll firm up as it cools).
Spices Too Strong?
Overpowering spices can ruin an otherwise perfect pie. If your filling tastes like a spice cabinet exploded, balance it with a touch of vanilla extract or a pinch of salt. I’ve also found that adding ¼ cup sour cream to the filling mellows out the heat while adding creaminess.
For future pies, start with slightly less spice—you can always add more, but you can’t take it out! A good rule of thumb: 1 tsp cinnamon per 2 cups filling is a safe starting point. 🌿
Crust Too Tough?
A tough crust is usually a sign of overworking the dough or not pre-baking it properly. If you’re using a store-bought crust, follow the package instructions for pre-baking. For homemade crusts, handle the dough as little as possible—just enough to fit it into the pie dish.
If your crust is already assembled but feels too stiff, brush it lightly with melted butter before baking. This adds moisture and helps create a flakier texture. Pro tip: Chill the crust for 15-20 minutes before adding the filling to prevent it from shrinking.
Pie Filling Too Sweet
If your pie tastes like a candy bar, the sugar content is likely too high. Start by reducing the sugar by ¼ cup next time—this makes a surprisingly big difference. Another trick is to add 1 teaspoon of lemon juice or ½ teaspoon of vinegar to the filling.
The acidity cuts through the sweetness and brightens the flavors. For a more balanced profile, increase the spices slightly—½ teaspoon of nutmeg or ¼ teaspoon of cloves add depth without overpowering. Taste as you go!

Frequently asked questions
Can I use just sweet potatoes or just yams in this recipe?
The combination of sweet potatoes and yams creates the perfect texture—creamy yet slightly firm. Using just sweet potatoes will make the filling denser, while yams alone may result in a slightly grainier consistency. For best results, stick with the 1:1 ratio, but if you must substitute, use 3 lbs sweet potatoes alone or 2.5 lbs yams for a similar effect. Roast them longer if needed to achieve the same tenderness.
How do I know when the sweet potatoes and yams are fully cooked?
They're done when a fork slides in easily with minimal resistance—no need to force it. The edges should pull away from the skin slightly, and the flesh should be soft enough to mash completely. Overcooking can dry them out, so aim for 45-50 minutes at 375°F. Pro tip: Press gently with your finger—they should yield like ripe avocado, not resist like a tennis ball.
Can I make this pie ahead of time?
Assemble the pie crust and filling up to 24 hours ahead, then refrigerate uncovered. Bake straight from the fridge (add 5-10 minutes to baking time). For make-ahead baking, freeze the assembled pie (unbaked) for up to 3 months. Thaw overnight in the fridge before baking. The flavors actually improve after resting—this is why many bakers swear by overnight chilling!
What's the best way to reheat leftover slices?
Warm slices in the oven for 5-10 minutes at 350°F until the edges are golden and the center is just warm. For microwave reheating, cover with a damp paper towel and heat for 20-30 seconds—this prevents drying. Never reheat straight from the fridge; let slices sit at room temperature for 10 minutes first to avoid condensation issues. The crust stays crispy when reheated properly!
Can I make this pie without a pie crust?
Yes! For a crustless version, simply pour the filling into a 9-inch pie dish or oven-safe skillet and bake as directed. The filling will set like a custard. For extra richness, top with a sprinkle of toasted pecans or a dollop of whipped cream before serving. This works especially well for individual servings—just divide the filling among ramekins and bake for 30-35 minutes instead.
