Preheat the oven to 350°F (180°C). Place the graham cracker crust on a rimmed sheet pan to make transferring to and from the oven easier. (This is also helpful to catch any spills.)
Whisk the filling ingredients in a large bowl until smooth (you can also use an electric mixer). Pour the custard filling into the prepared graham cracker crust.
15 ounces pumpkin puree, 1 can sweetened condensed milk, 2 eggs, 1 teaspoon ground cinnamon, ½ teaspoon salt, ½ teaspoon ground ginger, ¼ teaspoon ground nutmeg, ⅛ teaspoon ground cloves, 1 9- inch graham cracker crust
Place in the oven and bake for 50-60 minutes, or until set with a slight jiggle in the center. Insert a knife into the center of the pie to check doneness. If it is fully cooked, then the knife will be clean.
Remove from the oven and cool at room temperature for 1-2 hours, then place in the refrigerator to cool completely.
Notes
Important Note: If you use a homemade graham cracker crust, bake it at 350°F (180°C) for 8 minutes. Cool completely before filling.Substitutions:
Replace the spices (except for the salt) with 2 teaspoons of pumpkin pie spice.
Traditionally, vanilla extract is used in sweet potato pie, not pumpkin pie. But that's a matter of preference. If you enjoy the flavor of vanilla, add one teaspoon.
Substitute the sweetened condensed milk for 1 cup half and half or dairy-free milk, ¾ cup brown sugar, and 2 teaspoons cornstarch.
Use 1 ¾ cups of cooked and pureed fresh pumpkin instead of canned pumpkin puree.
Storage:Cool the pie completely before covering. Wrap tightly in plastic wrap and refrigerate for up to 3 days.For longer storage, freeze the pie for up to 1 month. Thaw overnight in the refrigerator before serving.
