Thank you to Log Cabin via Clever Girls Collective for sponsoring my post featuring my favorite french toast casserole with ...

Gooey cinnamon apples baked into this apple French toast ... Cover and refrigerate the casserole in the egg mixture for at least 30 minutes, or let it sit overnight covered in the refrigerator.

I took a shortcut, however, when it came to cutting up the squash and apples ... the gratin to make nice cheese layer, instead of dropping dollops of it around the casserole.
