Hello! Baking a pie evenly requires careful management of oven temperature and positioning. Typically, you want to start at a higher temperature like 425 degrees Fahrenheit on the lower-middle rack for 15 to 20 minutes to set the bottom crust, then reduce it to 375 degrees Fahrenheit for the remaining time to cook the filling fully.
To prevent the edges from burning while the filling cooks, you can cover the crust with a pie shield or a makeshift ring of aluminum foil about halfway through the baking process. I hope this helps you achieve a wonderfully balanced pie!
