Crust Preparation: Fit the pie crust into a 7-inch springform pan, ensuring it covers the base and sides.
Filling Preparation: In a mixing bowl, combine the pumpkin puree, sugars, spices, and salt. Add eggs one at a time, followed by the evaporated milk and vanilla. Mix until smooth.
Pouring: Transfer the filling into the crust, smoothing the top with a spatula.
Instant Pot Setup: Add 1.5 cups of water to the Instant Pot. Place a trivet or steamer rack inside. Place the pie on the trivet, using a foil sling for easier handling.
Cooking: Secure the lid, set to "sealing", and cook on "Manual" or "Pressure Cook" for 25-30 minutes at high pressure.
Natural Release: After cooking, allow for a natural pressure release for 10-15 minutes, then release any remaining pressure.
Cooling: Remove the pie and let it cool at room temperature before refrigerating for at least 4 hours or overnight.
Serving: Slice, serve, and enjoy your delicious Instant Pot Pumpkin Pie!
