Use cooking spray or butter to grease a 9" pie plate and roll out pie crust into it. Fill pie crust with filling
Bake for 40 minutes, adding a foil collar around the edge of the crust at 20 minutes
Notes
When baking pies, bake on a middle rack in the oven. Set a baking rack below it and center a baking tray underneath the pie plate. This prevents any possible overflow from burning on the bottom of your oven. To create a collar on the pie crust, lightly cover just the edge of the pie dish with tin foil to prevent the crust from burning while the filling is cooking. This can be done at the start of baking or halfway through.
