How to Make Overnight French Toast Casserole Recipe
Step 1: Prepare the Bread
Start by greasing a 9×13-inch baking dish to ensure your casserole doesn’t stick. Then, cut your choice of bread into 1-inch chunks. The size is important—it’s perfect for soaking up the custard without turning to mush. Place these bread cubes evenly in the baking dish, getting ready for the magic to begin.
Step 2: Make the Custard and Assemble
In a large mixing bowl, whisk together the eggs until they’re perfectly blended. Now add the heavy cream, milk, light brown sugar, cinnamon, salt, and vanilla extract. This mixture is what brings the casserole to life—rich, sweet, and laced with spice. Pour this custard evenly over the bread cubes, then gently toss everything once to ensure the bread is fully coated. Spread it back into an even layer in the pan, cover, and refrigerate overnight. This is the secret to deep, soulful flavor and tender texture.
Step 3: Prepare the Topping
The next morning, it’s time to make the irresistible crumb topping. Combine your brown sugar, granulated sugar, cinnamon, and nutmeg in a bowl. Add in the cold butter pieces and use a pastry blender or your fingers to work the butter into the mix until it forms crumbs. This little topping will bake into a golden, delightfully crunchy layer that perfectly contrasts the soft casserole underneath. Keep the topping in the fridge until you’re ready to bake.
Step 4: Bake to Perfection
Preheat your oven to 350 degrees Fahrenheit (180 degrees Celsius). Uncover the casserole, then evenly sprinkle the crumbly topping over the custard-soaked bread. Bake for 45 to 50 minutes or until the top turns a gorgeous golden brown and the casserole looks set—not jiggly. The baking locks in all those delicious flavors and gives the dish its show-stopping texture.
Step 5: Cool and Serve
Once out of the oven, let your Overnight French Toast Casserole Recipe cool for at least 10 minutes. This rest time is crucial as it helps everything set up perfectly without falling apart. When it’s time to serve, go wild with toppings like homemade syrup, fresh berries, or a dollop of whipped cream. It’s a breakfast that’s as fun to dress up as it is to eat.
How to Serve Overnight French Toast Casserole Recipe
Garnishes
While this casserole is fantastic on its own, the right garnishes can elevate it to superstar status. Fresh berries add vibrant color and a burst of tartness that cuts through the sweetness. Warm maple syrup or a drizzle of honey complements the cinnamon-spiced custard perfectly. Whipped cream not only adds creaminess but also creates a lovely visual contrast that makes every bite feel festive.
Side Dishes
Pairing your Overnight French Toast Casserole Recipe with thoughtfully chosen sides can turn breakfast into a full brunch affair. Crispy bacon or sausage links provide a wonderful salty counterpoint to the sweet, soft casserole. Fresh fruit salad refreshes the palate, while a simple green salad tossed with a bright vinaigrette can shock you by how well it balances this indulgent dish.
Creative Ways to Present
Don’t be afraid to get creative with how you present this dish. Try layering individual servings in glass jars topped with whipped cream and a sprig of mint for a charming look. Serving it family-style in the baking dish lets everyone scoop out generous portions, encouraging a cozy, communal breakfast vibe. Even sprinkling powdered sugar just before serving adds a touch of elegance that feels special.
Make Ahead and Storage
Storing Leftovers
Leftover casserole keeps wonderfully in the refrigerator for up to four days. Store it in an airtight container to preserve moisture and flavor. When you’re ready to dig in again, you’ll find the flavors have only deepened, making reheated slices just as comforting as the first bite.
Freezing
This Overnight French Toast Casserole Recipe freezes beautifully, making it an ideal make-ahead meal. Wrap portions tightly in plastic wrap and foil or place them in freezer-safe containers to avoid freezer burn. When you want a quick breakfast surprise, pull out a piece and thaw it overnight in the fridge before reheating.
Reheating
To bring leftover casserole back to life, reheat in a preheated oven at 350 degrees Fahrenheit until warmed through—usually about 15 to 20 minutes. For faster reheating, individual portions can also be heated in the microwave, but the oven helps keep the texture just right, especially if you want that crunchy topping crisped back up.
FAQs
Can I use any type of bread for this casserole?
Absolutely! Brioche, challah, French bread, or even sturdy white bread all work well. Just make sure the bread is slightly stale so it soaks the custard without disintegrating.
What makes this an “overnight” recipe?
The casserole needs to soak in the custard overnight in the fridge. This slow soaking allows the bread to absorb all those beautiful flavors fully, resulting in a tender, rich texture after baking.
Can I make this recipe dairy-free?
Yes, you can substitute the milk and heavy cream with non-dairy alternatives like almond or oat milk and use dairy-free butter for the topping. The texture might be slightly different, but it will still be delicious.
Is it possible to add fruit inside the casserole?
Definitely! Folding in fresh or frozen berries, sliced apples, or even chunks of peaches before refrigeration adds a lovely fruity surprise inside each bite.
How do I prevent the casserole from becoming soggy?
Cutting the bread into larger chunks, using bread that’s day-old or slightly stale, and ensuring the custard is well mixed and absorbed overnight helps maintain a perfect custardy texture without sogginess.

Ingredients
Main Ingredients
- 1 pound loaf of brioche, challah, French bread, or white bread, cut into 1 inch chunks
- 8 large eggs
- 1 cup heavy cream
- 2 cups milk
- 1/4 cup light brown sugar
- 2 teaspoons ground cinnamon
- 1/2 teaspoon kosher salt
- 1 tablespoon vanilla extract
Topping Ingredients
- 3 tablespoons light brown sugar, packed
- 3 tablespoons granulated sugar
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 2 tablespoons cold butter, cut into pieces
Instructions
- Prepare the Baking Dish and Bread: Grease a 9×13 inch baking dish to prevent sticking. Cut your chosen bread into 1-inch chunks and place them evenly into the prepared baking dish.
- Make the Custard Mixture: In a large mixing bowl, whisk together the eggs until smooth. Add the heavy cream, milk, 1/4 cup light brown sugar, 2 teaspoons ground cinnamon, kosher salt, and vanilla extract. Mix well to fully incorporate all ingredients.
- Assemble the Casserole: Pour the custard mixture evenly over the bread cubes in the baking dish. Toss gently to ensure all bread pieces absorb the custard. Spread the soaked bread into an even layer. Cover the dish and refrigerate overnight to allow flavors to meld and the bread to soak thoroughly.
- Prepare the Topping: In a small bowl, combine 3 tablespoons light brown sugar, 3 tablespoons granulated sugar, 1 teaspoon ground cinnamon, and 1/4 teaspoon ground nutmeg. Add the cold butter pieces and use a pastry blender or your fingers to mix until the mixture becomes crumbly. Cover and refrigerate the topping until ready to use.
- Bake the Casserole: Preheat your oven to 350°F (180°C). Remove the casserole from the refrigerator and uncover it. Evenly sprinkle the prepared crumb topping over the soaked bread. Bake uncovered for 45-50 minutes or until the topping is golden brown and the casserole is set in the middle.
- Cool and Serve: Once baked, allow the casserole to cool for at least 10 minutes before serving. This helps it set further and makes it easier to cut. Serve with your favorite toppings such as homemade syrup, fresh berries, or whipped cream for a delightful breakfast treat.
Notes
- Using brioche or challah will yield a richer and more tender casserole than plain white bread.
- If you prefer, soak the bread for at least 4 hours instead of overnight, but overnight soaking produces the best texture.
- For a dairy-free option, substitute milk and cream with almond or oat milk, though texture may vary slightly.
- To make ahead, you can prepare the topping and custard mixture separately and assemble just before refrigerating.
- Ensure butter for topping is cold for the best crumbly texture.
- Store leftovers covered in the refrigerator for up to 3 days; reheat gently to preserve texture.
