French Toast

  • 1 loaf dry French Bread (about 14-16 cups when cubed. MUST be a bit dry.)
  • 3 tablespoons butter
  • 2 cups half n half
  • 1/2 cup light brown sugar
  • 1 teaspoon cinnamon
  • 6 eggs
  • 1 teaspoon vanilla extract optional

Brown Sugar Topping

  • 1/2 cup flour
  • 1/2 cup brown sugar
  • 2-3 teaspoons cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup butter cut into pieces


  • 1 cup powdered sugar
  • 3 Tablespoons half n half or enough to make a thick glaze
  • 1/2 teaspoon vanilla extract


  • Preheat oven to 350 F.
  • Grease the bottom and sides of a 9x13 glass casserole dish.
  • Cut bread into cubes and place in casserole dish. Set aside.
  • In a saucepan, melt butter.
  • Add half n half, brown sugar and cinnamon.
  • Stir until sugar is dissolved, do not boil. Remove from heat and allow to cool a bit.
  • In a large bowl, beat eggs until uniform in color.
  • Stir warm half n half mixture into the eggs.
  • Add vanilla extract if using.
  • Pour just enough egg mixture ( YOU MAY NOT NEED IT ALL) *see note* over the bread cubes.
  • Toss the bread cubes gently so that all of them are covered in the egg mixture.
  • Cover and refrigerate for 30 minutes.
  • Make the crumb topping by combining flour, brown sugar, cinnamon and salt in a bowl.
  • Cut in the butter until crumbly.
  • When all or at least most of the egg mixture has been absorbed into the bread, remove it from the fridge and sprinkle with the crumb topping.
  • Bake for 55-60 minutes (check on it at the 45-minute mark since different breads seem to cook differently)
  • Remove from oven and allow to cool a bit.
  • Prepare the glaze by combining powdered sugar, half n half and vanilla until smooth.
  • Drizzle glaze over french toast casserole.
  • Serve hot!



When using challah or sourdough bread, you made need two loaves if they are on the smaller side.
