In a large bowl, combine the cream cheese, sugar, and egg; beat on medium speed until smooth. Add the pumpkin, cinnamon, and ginger and continue beating until well blended. Spoon mixture over the crust.
Bake for 40 to 45 minutes, or until set. Let cool then cover and chill for at least 4 hours or overnight
