The shortbread crust in this pie from chef Ronnie Woo is practically foolproof and the perfect buttery endnote for this spiced pumpkin pie filling.
For the shortbread crust, preheat oven to 350˚F. In the bowl of a stand mixer fitted with the paddle attachment, cream the butter, confectioners’ sugar and vanilla extract on high speed until light and fluffy. Add the flour and beat on medium speed just until combined. Dust your fingers and press the dough, piece by piece, into a pie dish until the dough covers the dish in a thin layer. Using a fork, prick a few holes into the bottom of the crust. Transfer to the oven and bake until lightly golden, about 12 minutes.
For the pumpkin pie filling, in a cast-iron skillet over medium-high heat, melt the butter. Add the pumpkin and salt and cook until tender, about 10-15 minutes, making sure to toss occasionally so the pumpkin does not burn. Transfer to a blender and add the brown sugar, cornstarch, ground nutmeg, ground cinnamon, vanilla extract, evaporated milk and eggs. Blend until smooth. Carefully pour into the prebaked pie crust and bake until puffed up with a slight jiggle, about 40-45 minutes.
Cool the pie for at least 4 hours or overnight. Before serving, evenly sprinkle the granulated sugar over the top of the pie and brulee with a culinary torch or in the broiler until sugar is melted and caramelized. Serve with whipped cream and a sprinkle of cinnamon.
