Notes

  • The best bread to use for French Toast is sourdough, challah, brioche and French bread. For this recipe I like sourdough. It holds up nicely and bakes perfectly delicious!
  • Prepare this casserole the night before you want to enjoy it because it gives the bread time to soak up the egg mixture. You'll want to let it soak at least 3-4 hours. 
  • If it comes out soggy, the bread you used might not have been hearty enough to soak up the egg mixture. Try using a more hearty bread next time or reducing the amount of milk.
  • Topping ideas including whipped cream, fresh berries, maple syrup and butter.
  • To reheat leftovers, cover the dish with tin foil and tuck it back into the oven for about 30 minutes or until it's hot - you'll know when it's done because you can smell the deliciousness! It will be best to reheat it in the oven, though you can certainly pop it in the microwave in a pinch.
Add-In Ideas!
  • Use a cinnamon swirl bread instead of sourdough.
  • Add in bacon for a savory combination
  • Chopped pecans make a delicious crunch in this casserole either in the topping or right in the batter. 
  • For a boozy twist mix in a few tablespoons of Amaretto or rum to the egg mixture.
