Overnight French Toast Makes Breakfast Easy

During the holiday season having an overnight breakfast prepped and ready makes everything so much easier! You can prep this casserole and bake it right away to enjoy right then or you can prep the evening before and place plastic wrap on top and keep it in the refrigerator overnight until you are ready to bake it in the morning.

  • loaf brioche bread
  • apple pie filling
  • large eggs
  • milk
  • heavy cream
  • vanilla extract
  • cinnamon
  • brown sugar
  • salt
  • butter

French Toast Casserole Instructions

I love brioche bread because it’s so buttery and delicious! So for this French Toast Casserole, I use brioche, but for this recipe, you could use any bread that you love. I that the slices of brioche bread and stack about 4 slices and then cut each into about 9 pieces.

I butter a large baking dish and then spread the chunks of brioche bread throughout the pan.

I use a can of apple pie filling to make this recipe super easy. I dump the filling onto a cutting board and cut the chunks of apples into bite-sized pieces. Then sprinkle the apple pieces over the top of the brioche bread.

Then it’s time to make the egg mixture. You’re basically creating a custard mixture that will make this breakfast casserole super creamy when you bake it up.

Whisk together the eggs, milk, cream, vanilla, and ground cinnamon in a bowl.

Then you will pour the liquid over the bread cubes. If you want to bake the apple french toast bake the same day, you still want to let the bread soak in the liquid so all the flavorings can get into the bread. I would recommend 30 minutes.

Personally, I like to cover the casserole at this point with plastic wrap and place in the refrigerator overnight. Now this casserole has one more step that I like to do in the morning while the oven is preheating. I will pull the casserole out of the refrigerator and start the oven preheating. Then on the stovetop over medium heat I will melt butter. Once it is melted I add brown sugar, cinnamon, and a litlte salt. Stir until the all that goodness is deliciously combined. Then take this sugar mixture and drizzle it over the top of the casserole.

Once you preheat the oven, you will bake the Apple Cinnamon French Toast Casserole for 45 minutes to an hour until the tops of the bread have started to brown.
