Preheat the Oven: Start by preheating your oven to 350°F (175°C).
Prepare the Pie Crust: Place your unbaked pie crust into a 9-inch pie dish, gently pressing it into the bottom and corners. Use a fork to prick the bottom to prevent bubbling.
Mix the Filling: In a large mixing bowl, whisk together 2 cups of pumpkin puree, 1 cup of heavy cream, 1 cup of brown sugar, 3 large eggs, 1/2 cup of bourbon, 1 tsp of vanilla extract, 1 tsp of ground cinnamon, 1/2 tsp of ground nutmeg, 1/4 tsp of ground ginger, and 1/4 tsp of salt. Mix until the filling is smooth and well-combined.
Pour the Mixture: Carefully pour the pumpkin mixture into the prepared crust, spreading it evenly with a spatula.
Bake the Pie: Place the pie in the preheated oven and bake for 50-60 minutes, or until the filling is set and a knife inserted into the center comes out clean.
Cool the Pie: Once baked, remove the pie from the oven and allow it to cool completely on a wire rack.
Add the Topping: Once cooled, sprinkle a thin layer of extra brown sugar across the top of the pie.
Caramelize the Sugar: To achieve that glorious brûlée topping, use a kitchen torch to caramelize the brown sugar until it's golden and bubbling. Alternatively, you can place the pie under the broiler for a few minutes—watching closely to avoid burning.
Slice and Serve: Let the pie cool for an additional 10 minutes before slicing. For an extra treat, serve individual slices with whipped cream or a scoop of vanilla ice cream!
