French toast bake with leftover bread pieces

I have a similar recipe on this site called French Toast Bake, but it has a different presentation as it uses whole bread pieces as opposed to irregular shaped bread pieces and crumbs.  If you have odd pieces left from people digging into bread with their hands as opposed to neat slices (as it often happens with homemade bread), this breakfast casserole is a perfect way to use up those odd bread pieces!

If you like challah bread, this is a perfect way to use up leftover challah! (If you want to make challah from scratch, check out my authentic challah recipe). Since challah is typically not sliced but torn up by hand, those challah pieces are a perfect material for this leftover bread breakfast casserole!  And if you do have neat challah slices, use them to make challah french toast!

How To Make Breakfast Casserole With Leftover Bread

Making this yummy breakfast bake with leftover bread is super easy! First, preheat the oven to 375F.  Spray a non-stick square 8×8 inch baking dish with cooking spray or grease it with butter.  Cut leftover bread into 1-inch cubes (or just tear into small pieces with your hands) and put it in the baking dish in a single layer.  On the picture below, I used leftover homemade challah that I just torn up into pieces.

In another bowl, whisk the eggs, milk, vanilla, cinnamon and sugar (the exact proportions are in the recipe card at the end of this article).

Make Ahead Breakfast Casserole

You can easily make this leftover bread casserole ahead of time and bake it later.  Simply assemble the casserole the night before, cover with plastic wrap and refrigerate.  This way the bread will have extra time to soak up all the milk and be extra soft and flavorful. Bake the casserole in the morning, so it will be piping hot and fresh for breakfast!
