Ingredients
  

  • 32 Ounces day old bread
  • 8 Large eggs
  • Cup whole milk
  • Cup maple syrup
  • Tablespoons cinnamon
  • 1 Teaspoon vanilla extract
  • ¼ Teaspoon salt

Crumb Topping

  • Cups old fashioned oats
  • ¼ Cup flour
  • ¼ Cup sugar
  • 2 Tablespoons brown sugar
  • 1 Tablespoon cinnamon
  • ¼ Teaspoon salt
  • ¾ Cup vegetable oil

Instructions
 

  • Preheat oven to 350°F. Prepare the day old bread by tearing it apart into roughly 2-inch pieces. In a large mixing bowl, add eggs, whole milk, maple syrup, cinnamon, vanilla extract and salt. Beat the egg mixture with a whisk or fork until fully combined and all of the eggs are broken apart.
  • Add the torn pieces of the day old bread into the egg mixture. Continue to stir everything gently with a large mixing spoon until the egg mixture completely coats the bread. Take care to not overmix. Add the bread and egg mixture into a pan sprayed 13x9 baking pan.
  • Prepare the crumb topping in a medium mixing bowl. Add old fashioned oats, flour, sugar, brown sugar, cinnamon and salt. Stir until combined. Slowly add in the vegetable oil and stir to completely coat the crumb topping mixture. Sprinkle the crumb topping generously over the top of the French Toast Breakfast Casserole.
  • Bake for 50 minutes or until a toothpick inserted into the center comes out clean. If you feel that your crumb topping is beginning to burn, you may cover the top of the baking pan loosely with aluminum foil. Allow to cool completely and slice into 12-15 squares. You may serve the casserole at room temperature. You may also microwave a slice for 30 seconds and serve with a side of butter and syrup.

Notes

For the day old bread, you can use whatever you have on hand that is leftover. There is a wide variety of breads that would be excellent for this casserole including: bagels, croissants, hotdog rolls, hamburger buns, Italian bread, panettone and more.
