Ingredients:

1 loaf French bread or thick Texas toast, cut into 1-inch cubes
8 large eggs
2 cups half-and-half
1/2 cup milk
3 Tablespoons granulated sugar
1 1/2 teaspoons pure vanilla extract
1/2 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg
1/2 teaspoon salt
1 1/2 sticks butter, softened
1 cup light brown sugar, packed
1 Tablespoon light corn syrup (optional)
1 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg

Prepare the Bread and Custard

First things first, let’s get our bread ready. You want to cut your loaf of French bread or thick Texas toast into roughly 1-inch cubes. Don’t worry too much about perfect uniformity; a little variation adds character. If you’re using day-old bread, even better! Stale bread absorbs the custard more beautifully and prevents the casserole from becoming soggy. Spread these bread cubes evenly into a greased 9×13 inch baking dish. Make sure the cubes are in a single layer as much as possible so they all get a good soak.
Now, let’s whisk up the luscious custard that will transform our bread into an irresistible Overnight French Toast Casserole. In a large mixing bowl, crack all 8 of your large eggs. Add the 2 cups of half-and-half, 1/2 cup of milk, 3 Tablespoons of granulated sugar, 1 1/2 teaspoons of pure vanilla extract, 1/2 teaspoon of ground cinnamon, 1/2 teaspoon of ground nutmeg, and 1/2 teaspoon of salt. Whisk everything together vigorously until it’s thoroughly combined and looks like a smooth, pale yellow liquid. You want to ensure the yolks and whites are completely incorporated.

Assemble and Chill

Gently pour the prepared custard mixture evenly over the bread cubes in the baking dish. Use a spatula or a large spoon to gently press down on the bread, encouraging it to absorb the custard. You don’t want to mash it, just a gentle push to ensure all those nooks and crannies get a good drenching. Let this mixture sit for about 10-15 minutes, giving the bread a chance to soak up even more of the liquid. This is a crucial step for achieving that perfect, custardy texture in your Overnight French Toast Casserole.
Now for the “overnight” part, which is where the magic truly happens. Cover the baking dish tightly with plastic wrap or aluminum foil. Place the entire dish in the refrigerator and let it chill for at least 8 hours, or preferably overnight. This extended chilling time allows the bread to fully absorb the custard, resulting in a delightfully tender and flavorful casserole. The longer it sits, the better it gets!

Prepare the Topping and Bake

The next morning, it’s time to prepare the decadent streusel topping that will add a delightful crunch and caramelized sweetness to your Overnight French Toast Casserole. In a medium bowl, combine the 1 1/2 sticks of softened butter with 1 cup of packed light brown sugar. If you’re feeling a touch indulgent, add the optional 1 Tablespoon of light corn syrup. Add the remaining 1 teaspoon of ground cinnamon and 1/2 teaspoon of ground nutmeg. Using your fingers or a pastry blender, work the ingredients together until the mixture resembles coarse crumbs. It should be slightly clumpy, not completely smooth.
Once your Overnight French Toast Casserole has chilled sufficiently, preheat your oven to 350°F (175°C). Remove the plastic wrap or foil from the baking dish. Sprinkle the prepared brown sugar streusel topping evenly over the entire surface of the soaked bread. Make sure to get a good, even coating for maximum deliciousness.
Bake the casserole in the preheated oven for 45-55 minutes, or until the topping is golden brown and bubbly, and the casserole is set in the center. You can check for doneness by inserting a knife into the center; it should come out mostly clean, though a little custardy moisture is perfectly fine. If the topping starts to brown too quickly before the casserole is set, you can loosely tent it with foil.

Frequently Asked Questions:

Can I make this Overnight French Toast Casserole ahead of time for more than one night?

While it’s designed for overnight, you can generally refrigerate the assembled casserole for up to two nights. The bread might become slightly softer the longer it soaks, but it should still bake up beautifully.

What kind of bread is best for this Overnight French Toast Casserole?

Sturdy, slightly stale bread works best, as it absorbs the custard without becoming too mushy. Challah, brioche, or even a good quality white bread are excellent choices. Avoid very soft, fresh bread.
