French Toast:

  • 1 loaf day old french bread (sour dough or challah work great too, about 10 cups)
  • 2 cups whole milk
  • 7 large eggs
  • 3/4 cup brown sugar
  • 3/4 teaspoon cinnamon
  • Pinch of salt


  • 1/2 cup salted butter (cubed)
  • 1/2 cup flour
  • 1/2 cup brown sugar
  • 1 cup berries (I used frozen)


  • Grease a 9×13″ casserole dish and set aside.
  • Cut the french bread loaf into cubes and layer evenly in the pan. You should have about 2 layers. Beat the milk, eggs, brown sugar, cinnamon and salt in a medium size bowl. Then pour evenly over the bread, making sure it covers each piece. Cover with foil and refrigerate over night, or at least 3 hours.
  • In a medium size bowl, mix together the butter, flour and brown sugar with a pastry cutter or two knives. Use your hands if needed to make crumbs. Cover and refrigerate.
  • When ready to bake, preheat oven to 350°F. Add the crumb topping on top of the bread and then evenly disperse the berries on top. Bake uncovered for 50-60 minutes, or until the top is lightly browned and the center is cooked through.
  • Enjoy by itself or topped with syrup.
