How to Make Apple French Toast Casserole

  • Prepare the baking dish. Grease a 9×13-inch baking dish with cooking spray or butter.
  • Add the bread. Place the cubed bread in the baking dish. Set it aside.
  • Mix the wet ingredients. In a large bowl, whisk the eggs, milk, and vanilla extract. Add half of the brown sugar and half of the ground cinnamon. Mix until well combined. Pour the mixture over the bread in the baking dish. Set it aside.
  • Cook the apples. Melt the butter in a large pan over medium-high heat. Add the apples, remaining brown sugar, and remaining ground cinnamon. Mix well. Cook them for 8 minutes, stirring constantly, or until the apples soften. Remove the apples from the heat.
  • Assemble the casserole. Spoon the apple mixture over the bread, sprinkle with pecans, and cover the baking dish with foil; refrigerate it overnight. You can also bake the casserole right away.
  • Bake it. Preheat the oven to 350˚F. Remove the baking dish from the fridge. Pop it in the oven (while still covered) for 30 minutes. Remove the foil and bake for another 20 minutes. Once the custard is set, remove it from the oven.
  • Serve. Let the casserole rest for at least 15 minutes before slicing. Finally, don’t forget to top it with lots of whipped cream, powdered sugar, sliced apples, and even granola. It’s amazing!

Overnight French Toast Casserole

  • French toast casserole can be made up to a day in advance. Assemble it and leave it covered in the fridge overnight or for up to 24 hours. Then bake and enjoy.
  • You can also freeze unbaked French Toast Casserole. Cover with two layers of aluminum foil and keep it in the freezer for 2 to 3 months. To freeze a baked casserole, please ensure it is completely cooled before putting it in the freezer.

Tips for Making a French Toast Bake

Follow these tips to keep yourself safe while handling the baking dish and make cleaning up easier:

  • Watch your face. Keep your face away from the baking dish when removing the foil from the baking dish before returning it to the oven. Steam tends to get trapped inside and will release violently when the foil is removed.
  • Don’t use wet towels. When managing hot baking dishes, never use wet or moist kitchen towels to remove them from the oven. They’ll heat up and burn your hands within seconds.
  • Use foil. Line your baking dish with foil for easy clean-up.
  • Use leftover bread. If all you’ve got is sandwich bread at home, use up all the leftovers to make this amazing casserole.

Serving Suggestions

I love this apple cinnamon French toast bake with a side of crispy bacon and scrambled eggs for breakfast. It’s like dessert and breakfast all in one. If I’m craving something lighter, I pair it with some Frozen Yogurt Bark with Berries and an Acai Bowl.

How to Store & Reheat Leftovers

  • Refrigerate any cooled leftovers in an airtight container for up to 3 days. It will technically last up to 5 days, but the texture will soften too much after the third day. You can also refrigerate it in the baking dish as long as you cover it with foil.
  • To reheat it, sprinkle it with a couple of teaspoons of water and then microwave it until warm. You can also reheat it in the oven at 350˚F, covered, for 10 minutes or until heated through.

Instructions
 

  • Butter a 9×13 baking dish. Place the bread cubes in the baking dish and set aside.
  • In a mixing bowl, whisk together the eggs, milk, ¼ cup brown sugar, 1 teaspoon cinnamon, and vanilla. Pour the egg mixture over the bread; stir and set aside.
  • Melt butter in a large skillet set over medium-high heat. Once melted, add in the apples, remaining brown sugar, and remaining cinnamon. Cook for about 8 minutes, stirring frequently, until the apples begin to soften and the liquid thickens.
  • Remove from heat and spoon the apple mixture over the bread mixture. Sprinkle the top with pecans.
  • Cover with aluminum foil and refrigerate overnight, or bake it right away.
  • Preheat the oven to 350˚F.
  • Take the casserole out of the fridge and let it sit on the counter while the oven is preheating.
  • Bake, covered, for 30 minutes.
  • Remove the foil and continue to bake for about 20 more minutes or until the custard has set.
  • Remove from oven and let stand 15 minutes before cutting and serving.
  • Top with maple syrup and serve.

Notes

  • Bread: Brioche is most commonly used for French toast, but sourdough bread, ciabatta, or challah are also excellent choices. Leftover, dry, or stale bread works best.
  • Apples: I like to use any fresh apples I have on hand, mostly Honeycrisps, but Granny Smith apples are good to use, as well as Jonathans. 
  • Freezing French Toast Casserole: Fully cooked casserole can be frozen – cover with a couple of layers of foil and freeze for up to 3 months. However, I suggest freezing the French toast casserole before baking because it produces a better, more firm texture.
  • Baking: This casserole can be baked right away, or for a better-tasting French toast, prepare the casserole, but don’t bake it. Cover the baking dish with foil, store it in the fridge, and let the casserole sit overnight or for at least 4 hours – this gives the bread a chance to soak up the egg custard.
