This leftover bread breakfast casserole is amazing! Even if your bread pieces are all torn up into irregular shapes and crumbs, they make an outstanding french toast bake!

Once you try making this mouthwatering breakfast french toast bake, you’ll never throw out leftover bread ever again!  Browse all my recipes for using food scraps and leftovers to minimize food waste and turn trash into treasure :)

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!

This easy breakfast casserole is so delicious! Bread pieces are soaked in a mixture of milk, eggs, sugar and vanilla, then baked in the oven till puffy golden-brown perfection!

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).

Pour the milk mixture over the bread pieces and sprinkle some more sugar on top.  Let the bread soak for 10 minutes.

Bake the leftover bread casserole for 30 minutes, or until set.

Slice the leftover breakfast bake into pieces and serve warm with maple syrup.

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!

If you don’t finish this breakfast bake all at once, you can refrigerate it for later.  Simply warm the leftovers in a microwave before serving and enjoy!
