Bake in preheated oven until set and lightly browned, 5 to 7 minutes. Cool for 10 minutes.

Step 4
Meanwhile, beat cream cheese and brown sugar in a large bowl until smooth. Stir pumpkin, cornstarch, 1 1/4 teaspoons cinnamon, and nutmeg into cream cheese mixture. Gradually beat in evaporated milk and eggs until just blended; pour into crust. Place pan on a baking sheet.

Step 5
Bake in preheated oven until center is almost set, 55 to 60 minutes.
