  • 16 ounces French Bread cut into cubes, and dried (see note)
  • 8 eggs
  • 2 cups whole milk
  • 2 teaspoons vanilla extract


  • 1/2 cup unsalted butter
  • 1 cup brown sugar packed
  • 1/2 cup quick cooking oats

  • In a large bowl combine the eggs, milk, and vanilla extract. Whisk until all the eggs are fully broken down and the mixture is smooth.
  • Toss the egg mixture with the eggs until all of the bread is fully coated. Pour the mixture into the prepared baking dish. Cover with aluminum foil and place in the refrigerator overnight.
  • The following morning preheat the oven to 350 degrees.
  • In a small bowl, using two forks a pastry cutter, combine the butter, oats, and brown sugar.
  • Remove the casserole from the refrigerator, top with the streusel, and bake for 40 minutes or until the casserole begins to pull away from the sides of the baking dish.
  • Cut, serve, and enjoy with powdered sugar and syrup.


You are looking for approximately 10 cups of dried bread cubes. If you buy a 16 ounce loaf of French bread, cut it into cubes and dry over night, you can use all of that. You can also put the fresh soft cubes onto parchment lined baking sheets and bake for 30 minutes at 250 degrees (toss half way through baking) and use right away.
