Double key lime pie filling and increase from 9" to 10" shell, new baking time? I want to double the key lime pie recipe and put it in a 10 inch pie crust instead of a 9 inch pie crust. How much do I have to increase the baking time? The pie has a graham crust.
Since you increased the thickness, you likely need to reduce the baking temperature somewhat (perhaps 25 degrees?) and bake longer. My best guess would be 25-50% longer, but you'll want to just start checking for doneness sometime around the original baking time. It should be mostly set but still a bit jiggly. If the crust is cooking too fast you can also cover the edges with foil to keep it from browning too much or burning.
