One of our favorite things to make for our Christmas morning breakfast is this Overnight French Toast Casserole.

Not only does it taste absolutely delicious, but it actually is made the day before the big holiday.

So all that is required in the morning is to put the casserole in the oven and let it bake.

No standing over a hot griddle making individual servings of French Toast slices.

Instead, you can enjoy extra time with your family. And everyone can eat at the same time, including you!

Overnight French Toast Casserole Recipe

Because this is a casserole recipe, the ingredients list is a little larger than when making standard French Toast.

Not only will you need a few more eggs to bind the bread together when baking. You will also add a crumb topping to the top that is to die for!

Ingredients Required

  • Loaf of thick bread
  • Eggs
  • Milk
  • Heaving Whipping Cream
  • White and Brown Sugar
  • Vanilla Extract
  • Cinnamon
  • Flour
  • Salt
  • Butter


This Overnight French Toast Casserole recipe requires thick bread slices instead of the thin slices of bread that you use to make a sandwich.

You can find a loaf of Texas Toast bread in most grocery stores. However, if you can’t seem to find it, you can use Sourdough or a French Bread Loaf from the bakery.

Day old, slightly stale bread works best for this recipe as it stands up firm to the baking process. However, if you buy a fresh loaf of bread, you can definitely still make this recipe.

First, cut your bread slices into 1-2 inch cubes. Then let it air dry so that the bread becomes hardened.

If you are short on time, you can also place the bread cubes on a rimmed baking sheet and place it in a preheated oven set at 250°F for 10-15 minutes.

Remember, you want the bread firm and dried, but not toasted.

Next, place the dried out bread in the bottom of a 9 x 13 baking dish that has been sprayed with non-stick spray and set aside.

Now it is time to prepare the custard that will bind the French Toast Casserole together.

Wet Ingredients

In a large bowl add the eggs, milk, cream, sugars, vanilla and cinnamon. Whisk the mixture until well incorporated.

Next, pour the liquid over the cut bread pieces that are in the casserole dish.

Using a spatula, lightly press the bread pieces so that each one has been coated with the egg mixture.

Cover and refrigerate for several hours, or preferably overnight.

Prepare the Crumb Topping

In a medium bowl add the topping ingredients. Using a pastry cutter or fork, cut the butter into the dry ingredients until it forms small crumbles.

A little patience is required here. It will take a few minutes for the butter to become part of the mixture.

Once the mixture is nice and crumbly, cover and refrigerate until you are ready to bake the French Toast Casserole.

Baking Instructions

In the morning, take the casserole dish out of the refrigerate and preheat the oven.

While you wait for the oven to heat up, sprinkle the crumb topping on top of the bread. You will notice that the bread has soaked up the egg and milk mixture.

Once the oven is preheated, bake for 45-60 minutes. If you like your French Toast casserole to be a little more moist, remove from the oven at the 45 minute mark.

However, if you like it a little more firm, I would suggest baking it for up to 60 minutes.

When you remove the casserole from the oven, it will be inflated. No worries, once it is removed from the heat the bread will deflate.

Therefore, let it cool for 5 minutes before serving. Top with maple syrup, powdered sugar, or fruit!

  • 2 cups milk
  • 1/2 cup heavy whipping cream
  • 1/2 cup granulated sugar

  • 2 tbsp vanilla extract
  • 1 1/2 tsp ground cinnamon

  2. Cut bread into 1 inch chunks and spread evenly in the bottom of the casserole dish.
  3. In a large bowl, whisk together the eggs, milk, cream, sugars, vanilla and cinnamon. Pour the mixture evenly over the bread and toss to coat the bread in the egg mixture.
  4. Cover the casserole and store in fridge for several hours or overnight.


  1. In a medium mixing bowl, mix together flour, brown sugar, cinnamon and salt. Add butter and cut into the flour mixture with a fork or pastry cutter until it forms a crumble. Store in the refrigerator.
