Step 6: Top, bake, and serve
Bake at 350 until cooked through and golden-brown on top, around 45 minutes. The insides will bubble up to let you know they're ready.
Brushing the top with milk or egg white near the end of the cook time will make it brown more nicely.
This pie serves MUCH more easily when cool, and the flavors are more subtle and interesting. Thus, if you can make the pie a day ahead of serving you should; more importantly, it means that this pie will taste even better for breakfast!
