Ingredients
Method
- Make the crust: Combine flour, sugar, and salt. Cut in cold butter until mixture resembles coarse crumbs. Add ice water 1 tablespoon at a time until dough just comes together. Shape into a disk, wrap, and refrigerate 30 minutes.
- Preheat oven to 375°F (190°C). Roll out dough and fit into a 9-inch pie pan. Crimp edges and blind bake for 10 minutes. Remove and let cool slightly.
- Reduce oven to 325°F (165°C).
- Make sweet potato filling: Whisk together mashed sweet potatoes, melted butter, brown sugar, granulated sugar, eggs, heavy cream, vanilla, cinnamon, nutmeg, ginger, and salt until smooth.
- Pour sweet potato filling into the par-baked crust, spreading evenly.
- Make cheesecake layer: Beat softened cream cheese and sugar together until smooth and fluffy. Add eggs one at a time, mixing after each. Mix in sour cream, vanilla, and salt.
- Gently pour cheesecake mixture over the sweet potato layer, spreading carefully to cover.
- Bake at 325°F for 50–60 minutes until cheesecake is just set with a slight jiggle in the center. Turn off oven, crack door, and let cool inside for 30 minutes to prevent cracking.
- Cool completely at room temperature, then refrigerate for at least 4 hours or overnight before slicing and serving.
Notes
Storage: Refrigerate covered for up to 5 days. This pie actually improves overnight as the layers meld. Freezing: Freeze fully baked and cooled pie (without toppings) for up to 2 months; thaw overnight in the refrigerator. Tips: Use full-fat cream cheese for best texture. Ensure cream cheese is fully softened before mixing to avoid lumps. Do not overbake — the cheesecake center should have a slight jiggle. Substitutions: Use a store-bought pie crust or graham cracker crust to save time.
