Ingredients

  • 4 refrigerated rolled pie crusts should be 2 boxes

For the Sweet Potato Filling

  • 2/3 cup granulated sugar
  • 5 tbsp unsalted butter room temperature
  • 1 large egg
  • 1/4 tsp vanilla extract
  • 1 2/3 cup sweet potato fully cooked and mashed
  • 3/4 tsp ground cinnamon
  • 1/4 tsp ground nutmeg
  • 1/4 tsp salt
  • 1/3 cup evaporated milk

For the Pecan Pie Filling

  • 3/4 cup light brown sugar
  • 1/2 cup light corn syrup
  • 4 tbsp unsalted butter melted and cooled
  • 1 large egg plus 1 egg yolk
  • 1 tsp vanilla extract
  • 2 cups pecans roasted and roughly chopped
  • kosher salt

For the Pumpkin Pie Filling

  • 1 1/2 cup pumpkin puree
  • 1/4 cup evaporated milk
  • 1/2 cup granulated sugar
  • 1/2 tsp kosher salt
  • 1 large egg
  • 2 tsp pumpkin pie spice see note below

Instructions

For the Crust

  • Preheat the oven to 350 degrees F. Unroll 3 of the pie crusts on a lightly floured work surface. Stack them on top of each other. Roll out the thick, layered dough to a 15-by-21-inch rectangle. Press into a rimmed baking sheet so that the crust comes up the sides and hangs over slightly. This will be the bottom crust. Chill until ready to use, at least 30 minutes.

For the Pumpkin Pie Filling

  • Whisk together the pumpkin, evaporated milk, sugar, salt, pumpkin pie spice and the egg and in a medium bowl until smooth. Cover and set aside.

For the Pecan Pie Filling

  • Whisk together the brown sugar, corn syrup, butter, vanilla, eggs and a pinch of salt in a medium bowl until smooth. Fold in the pecans, cover and set aside.

For the Sweet Potato Pie Filling

  • Using a stand mixer or a hand held mixer, beat together the butter and sugar, then carefully add in the egg and vanilla. Once combined, add in the cinnamon, nutmeg, salt and mashed sweet potato. As the mixture begins to smooth out, gradually pour in the evaporated milk. Mix until fully incorporated, cover and set aside.

To Assemble

  • Once all fillings are made, begin assembling the pie. Remove the baking sheet with dough from the refrigerator. Using a fork, poke the pie crust about a dozen times, going all around the dough (except for the crust).
  • Using a large spatula, carefully scoop, spread and smooth each filling onto the crust. On the left side, start with the sweet potato and allow it to only take up ⅓ of the pan. Next, scoop and spread the pecan filling in the middle. Because there is a bit more liquid in the pecan mixture, it will spread a bit, do your best to control it by quickly scooping, spreading and smoothing the pumpkin mixture on the right side.
  • Bake until all pies are set and the crust on the pie is golden brown and crisp, 50 to 60 minutes.
  • Remove the pie from the oven and allow it to completely cool, about 1-1 ½ hours. Tightly cover the top with aluminum foil (or plastic wrap) and transfer to the refrigerator to set for at least 4 hours. Overnight is best.
  • Allow the pie to sit at room temperature for at least 30 minutes before serving. Slice, serve and enjoy!

Notes

If you don't have pumpkin pie spice for the pumpkin pie filling, add 1 tsp ground cinnamon, ½ tsp ground ginger, ¼ allspice, ¼ tsp cloves, pinch of nutmeg.
*There will be leftover dough! It can be used to decorate the tops of the pies or saved for a smaller project.
