Ingredients in Overnight French Toast Casserole

Here’s what you’ll need to create this irresistible casserole:

Bread

Stale or slightly dry bread works best here! A thick, hearty bread like challah, brioche, or French bread soaks up the egg mixture and bakes up beautifully. It’s the base of the casserole and absorbs all the goodness.

Eggs

Eggs are the key to making the casserole custardy and rich. They provide the perfect texture and make the casserole feel like you’re eating the fluffiest French toast ever.

Milk and Cream

A mix of milk and heavy cream gives the casserole a rich and smooth texture. You could also use a dairy-free milk if you prefer!

Brown Sugar

Brown sugar gives a lovely depth of sweetness and a subtle molasses flavor that complements the cinnamon and vanilla.

Cinnamon and Vanilla

Classic French toast spices—cinnamon and vanilla—bring warmth and depth to the casserole. It’s what makes each bite feel like a cozy hug.

Butter

A little butter adds richness and helps give the casserole that golden, crispy topping you’ll love.

Streusel Topping (Optional)

If you like a little extra crunch, you can sprinkle a buttery, sweet streusel topping over the casserole before baking. It adds a delightful texture and sweetness that makes each bite even more irresistible.

Instructions

Ready to dig in? Here’s how you can make this Overnight French Toast Casserole:

Prepare the Casserole

Start by buttering a 9×13-inch baking dish. Layer the bread slices in the dish, packing them in tightly. You want them to be arranged neatly, but don’t stress about it being perfect—just make sure each slice has some space to soak up the egg mixture.

Make the Egg Mixture

In a large bowl, whisk together the eggs, milk, heavy cream, brown sugar, cinnamon, vanilla, and a pinch of salt. Pour this mixture evenly over the bread slices, making sure every piece of bread is soaked. If you want a richer casserole, feel free to add a bit more cream or sugar.

Refrigerate Overnight

Cover the baking dish with plastic wrap or foil and pop it in the fridge overnight. This allows the bread to soak up the custard, making the casserole extra soft and flavorful.

Add Streusel Topping

In the morning, preheat your oven to 350°F (175°C). For a crispy, sweet topping, prepare the streusel by combining flour, butter, brown sugar, and a pinch of cinnamon. Sprinkle this mixture over the casserole before baking. The streusel will bake into a golden, crispy topping that adds the perfect texture.

Bake to Golden Perfection

Bake the casserole in the preheated oven for 45-50 minutes, or until the top is golden brown and the center is set. You’ll know it’s ready when the casserole is puffed and the edges are slightly crispy.

Serve and Enjoy

Let the casserole cool for a few minutes, then slice and serve with your favorite toppings—syrup, fresh fruit, whipped cream, or a dusting of powdered sugar. Enjoy!

How to Serve Overnight French Toast Casserole

This casserole is fantastic on its own, but here are a few ways to make it even more delicious:

With Maple Syrup

Serve it with warm maple syrup drizzled over the top for that classic French toast experience. Add some fresh berries or sliced bananas for an extra fruity touch.

Fresh Fruit

Top your casserole with a mix of fresh berries, sliced bananas, or even warm sautéed apples for a seasonal twist.

Whipped Cream

A dollop of whipped cream is the perfect finishing touch, making each bite feel like a special treat.

Bacon or Sausage

Pair this casserole with crispy bacon or savory sausage for a well-rounded breakfast or brunch.

Powdered Sugar

For a sweet and simple garnish, sprinkle some powdered sugar over the top right before serving. It adds a little sweetness and looks beautiful.

Additional Tips

Make Ahead

You can prepare the casserole the night before and store it in the fridge overnight. If you prefer, you can bake it immediately after assembling, but the soaking time makes a huge difference in the texture.

Use Stale Bread

Day-old bread works best because it soaks up the custard mixture more evenly, giving you a soft and custardy texture. If your bread is fresh, just leave it out for a few hours before using it.

Freeze for Later

Want to make this breakfast ahead of time and freeze it for a busy day? Assemble the casserole, cover it tightly, and freeze it before baking. When you’re ready to bake it, let it thaw in the fridge overnight, then bake as directed.

Add Flavor Variations

Want to make your casserole unique? Try adding chocolate chips, diced apples, or even caramelized nuts for a twist on this classic dish. The possibilities are endless!
