  • Grease a 9x13 baking dish with cooking spray.
  • Cube the bread into small 1-inch cubes, and layer with the pecans in the prepared baking dish.
  • In a large mixing bowl, mix together the diced apples, melted butter, sour cream, sugar, brown sugar, corn starch, cinnamon, nutmeg, and lemon juice.
  • Toss the apple mixture with the bread and pecans in the baking dish.
  • In a large mixing bowl, whisk together the eggs, milk, vanilla extract, and salt.
  • Pour the egg mixture over the bread cubes and pecans in the baking dish, making sure all of the bread is soaked with the egg mixture.
  • Cover and chill for a good 4 to 6 hours or overnight.
  • When you're ready to bake the casserole, remove it from the fridge, and preheat the oven to 350° F.
  • In a small mixing bowl, mix together the sliced butter, brown sugar, and cinnamon.
  • Crumble or clump the topping over the entire breakfast casserole.
  • Cover the baking dish with aluminum foil, and bake at 350° F for about 40 minutes. Then uncover and continue baking for an additional 15-20 minutes.
  • Once it's thoroughly cooked through, remove it from the oven and let it cool for just a few minutes.
  • Then slice and serve with powdered sugar and/or maple syrup.



*20 ounces equals about 22 slices. Keep in mind you can also use Texas toast, sourdoughchallah breadFrench bread, or really any other type of fresh baked bread; but it may change the texture of the casserole.
*Pecans are totally optional; you can also use walnuts.
*My favorite apples to use for recipes like this include Jonathan, Jonagold, Granny Smith, Golden Delicious, and Honeycrisp.
