Yield: 8 Servings

Prep Time: 30 mins

Cook Time: 2 hrs

Total Time: 3 hrs 30 mins

For the Gluten-Free Pie Crust:

• 8 tablespoons (113.6 g) unsalted butter, cut into small cubes and frozen for 10 minutes (for dairy-free, use cold plant-based butter or coconut oil)
• 2 ½ tablespoons (2.5 tbsp) ice water
• 1 ½ tablespoons (1.5 tbsp) sour cream (for dairy-free, use dairy-free sour cream or full-fat coconut milk solids)
• 1 ½ teaspoon (1.5 tsp) apple cider vinegar
• ¾ PLUS ⅔ cup (184 g or 6 ½ ounces total) gluten-free all-purpose flour blend (Cup4Cup is highly recommended for best results due to its balanced starch and gum content)
• 1 ½ teaspoon (1.5 tsp) granulated sugar
• ½ teaspoon (0.5 tsp) salt

For the Sweet Potato Pie Filling:

• 1 ½ pounds sweet potatoes (about 3-4 medium yams), roasted until very tender and cooled
• ¾ cup light brown sugar, packed
• 6 tablespoons unsalted butter, very soft (for dairy-free, use very soft plant-based butter)
• 1 large egg
• 2 egg yolks
• 1 teaspoon vanilla extract (omit if using bourbon for optimal flavor balance)
• 1 teaspoon ground cinnamon
• ½ teaspoon ground ginger
• ¼ teaspoon ground nutmeg
• ⅛ teaspoon ground cloves
• ¼ teaspoon salt (reduce to ⅛ teaspoon if using full-fat coconut milk for dairy-free option, as it can be naturally saltier)
• ¾ cup evaporated milk (for dairy-free, use full-fat coconut milk from a can, chilled overnight and solids scooped off)
• Optional: Up to ¼ cup bourbon (if using, reduce evaporated milk by the same exact amount to maintain consistency)
• Optional Toppings: Whipped cream, candied pecans, meringue, toasted marshmallows, or whipped coconut cream for serving.

For the Gluten-Free Pie Crust:

1. Place the cubed unsalted butter in the freezer for at least 10 minutes to ensure it’s very cold. In a small separate bowl, thoroughly mix together the ice water, sour cream, and apple cider vinegar. Keep this liquid mixture in the refrigerator until you are ready to incorporate it.
2. If using a food processor: Pulse the gluten-free flour blend, granulated sugar, and salt together until thoroughly combined and uniform. If mixing by hand: Whisk these dry ingredients together in a medium-sized bowl to ensure even distribution.
3. If using a food processor: Add the frozen butter cubes to the flour mixture and pulse repeatedly until the butter is well incorporated into the flour, resembling coarse meal with no large chunks remaining. If mixing by hand: Use a pastry blender, a fork, or your fingertips to carefully cut the butter into the flour mixture until it is evenly distributed and resembles coarse crumbs.
4. If using a food processor: Gradually add the chilled liquids (water, sour cream, vinegar mixture) to the food processor and pulse just until the flour becomes moistened and small clumps of dough begin to form. If the dough seems too dry and doesn’t quite come together, add a tiny dash more cold water, pulsing a few times, and recheck the consistency. If mixing by hand: Add half of the chilled liquids and gently knead with your fingers or a fork until somewhat combined. Pour in the remaining liquids and continue to knead until the dough just starts to come together and the liquids are thoroughly mixed with the flour.
5. Tip for perfect dough consistency: To check if you have achieved the right moisture level, take a small bit of dough, clump it together, and gently flatten it. If it doesn’t stick together, is crumbly, or breaks apart easily, add another small dash of ice water and mix briefly. If, conversely, the dough becomes too wet or sticky, add a dash of gluten-free flour and mix again until manageable.
6. Turn the dough out onto a sheet of plastic wrap and gently flatten it into a thick, 1-inch disk. Wrap it tightly and refrigerate for at least 1 hour, or freeze for 30 minutes. Before rolling out, let the chilled dough sit on the counter for about 5 minutes to soften slightly, making it much easier to work with without cracking.
7. Prepare your workspace by laying a large piece of parchment paper. Place the unwrapped dough disk in the center, then cover it with another sheet of parchment paper of the same size. Use a rolling pin to press and spread the dough outwards from the middle, rotating it as you go, until it forms a uniform circle slightly larger than your pie dish.
8. Remove the top parchment paper and carefully invert the dough onto your pie dish. Gently peel off the second sheet of parchment paper. Troubleshooting Tip: If the dough has warmed up significantly while rolling and becomes tricky to remove from the paper, simply leave the paper on and place the entire pie dish (with dough and paper) into the fridge for 5-10 minutes. Once thoroughly chilled, the paper will peel off much more easily. Conversely, if the dough is too cold and cracks when handling, let it sit on the counter for a minute to warm slightly before attempting to fix.
9. If necessary, meticulously trim the edges of the dough to leave an even ½-inch overhang all around the pie dish. Tuck this overhang under itself, creating a neat, thick edge. Then, use your fingers and thumb to crimp or create a decorative edge, as desired, for a beautiful presentation.
10. Preheat your oven to 375ºF (190ºC). Place the prepared pie crust in the freezer for at least 15 minutes while you begin roasting your sweet potatoes.
11. Once the crust is solid from freezing, line the pie shell with parchment paper and fill it completely with dried beans or a pie weight. Cover the edges of the crust with a pie shield or carefully secure aluminum foil strips around them to prevent any unwanted over-browning.
12. Bake the crust in the preheated 375ºF oven until it is just set and appears dry, but critically, before it starts to turn golden brown. This should take approximately 25-30 minutes. For maximum efficiency, the pie crust can be baked alongside the roasting sweet potatoes during this time.

For the Sweet Potato Filling & Final Baking:

13. Preheat the oven to 375ºF (190ºC) if not already on for roasting potatoes. Line a baking sheet with foil or parchment paper. Prick the washed sweet potatoes 5-6 times with a fork and place them on the lined sheet. Bake until they are very soft and tender, approximately 50-60 minutes.
14. Once the potatoes are roasted and cool enough to handle comfortably, scoop the tender flesh from their skins into a large mixing bowl, discarding the skins. Using an electric mixer, beat the sweet potato flesh thoroughly until it forms a smooth, lump-free puree. Reduce oven temperature to 350ºF (175ºC) for the final pie baking.
15. Add the very soft butter, light brown sugar, large egg, two egg yolks, vanilla extract (if not using bourbon), ground cinnamon, ground ginger, ground nutmeg, ground cloves, and salt to the sweet potato puree. Beat again with the electric mixer until all ingredients are thoroughly combined and the mixture is smooth and uniform. Then, gradually mix in the evaporated milk until fully incorporated and the filling is homogenous. (If using bourbon, remember to omit vanilla and adjust milk quantity as per ingredient notes).
16. Carefully pour the velvety sweet potato mixture into your pre-baked crust, ensuring the crust is lightly browned and perfectly set before filling. Meticulously cover the edges of the pie crust with a pie shield or securely with aluminum foil strips to prevent them from burning during the final bake.
17. Bake the pie in the 350ºF (175ºC) oven for about 60-75 minutes, or until the edges of the filling are firmly set and slightly cracked, and a toothpick inserted into the middle comes out mostly clean, with a slight, delicate jiggle remaining in the very center. Refer to the “How Do I Know When The Pie Is Done?” section for detailed indicators.
18. Remove the baked pie from the oven and carefully place it on a wire rack to cool completely. This cooling process is absolutely vital for the filling to set properly and for the complex flavors to deepen and meld beautifully. Allow at least 3-5 hours for cooling before attempting to slice and serve. For the absolute best taste and texture, we strongly recommend making the pie one full day ahead of serving, allowing the flavors to fully develop.

Dairy-Free Modification for a Delicious Alternative:

To prepare an equally delicious dairy-free version of this exquisite pie, you’ll need to make a few simple yet effective substitutions. First, for the crust, utilize a specialized gluten-free and dairy-free pie crust recipe; ensure it’s designed to be flaky and holds up well during baking. For the filling, replace the evaporated milk with an equal amount of full-fat canned coconut milk (for best results, chill the can overnight and scoop off only the thick cream that rises to the top). Additionally, substitute the unsalted butter with a high-quality vegan butter alternative. When using coconut milk, you may also want to slightly reduce the salt in the filling to 1/8 teaspoon, as certain brands of coconut milk can sometimes have a naturally saltier profile, which you’ll want to balance.

Storing and Make-Ahead Notes for Convenience:

For enhanced flavor development and unparalleled ease during busy holiday seasons, we highly recommend baking this sweet potato pie one full day before you plan to serve it. This crucial resting period allows the complex spices and rich flavors to truly meld and deepen, resulting in a more harmonious, robust, and ultimately more delicious pie. Store the baked pie at room temperature, either uncovered or loosely tented with foil, to prevent any condensation from forming and softening the crust.

To further streamline your baking process and reduce stress, many components of this recipe can be prepared efficiently in advance:

• Gluten-Free Pie Crust Dough: The unbaked gluten-free pie crust dough can be made up to two days ahead of time and safely refrigerated, tightly wrapped in plastic. For longer storage, it can be frozen for up to two weeks. If frozen, thaw it completely in the refrigerator overnight before attempting to roll it out.
• Roasted Sweet Potato Puree: The roasted sweet potato puree can be prepared up to one day in advance and stored in an airtight container in the refrigerator. This saves significant time on baking day.
• Mixed Filling (Unbaked): The entire filling mixture (prior to baking) can be mixed together up to one day ahead and refrigerated in an airtight container. If you do this, allow it to come closer to room temperature for about 30 minutes before pouring it into the pre-baked crust for more even and consistent baking.

Once baked, the pie can be stored at room temperature, covered with foil, for up to two days, maintaining its delightful texture and flavor. For extended freshness, you may refrigerate the pie, covered with foil, for up to three days. For optimal taste and texture, always allow any refrigerated pie to come back to room temperature before serving; this truly brings out its full flavor profile and creamy consistency.
