This is one of those recipes that is super for a last minute meal. When we were out shopping a few days before I made this I picked up a loaf of Italian style bakery bread (the big oval loaves) and left it out on the counter to dry for a day or two. I find I like this casserole a bit better if the bread is slightly tough. It seems to soak up the eggy batter better and not be as mushy as some French toast casseroles.
Verdict: This is a recipe you kind of have to do by feel. Make sure there are enough eggs and milk to soak into the bread but not too much to drown the bread and be all eggs. As you pour the egg mixture over the top you can tell if you have enough if the bread looks like it is soaking it in.
This is a sweet cinnamon roll type of breakfast casserole that is also great for dinner or brunch. We serve this with a side of fruit salad for dinner.
