- Large Eggs: These give the casserole its velvety, rich custard base—don’t worry, it won’t taste eggy.

- Heavy Cream: Adds that ultra-decadent, creamy texture everyone raves about.
- Granulated Sugar: Sweetens the custard just right without overwhelming the other flavors.
- Brown Sugar: Brings a subtle toasty depth and keeps the casserole from cloying sweetness.
- Vanilla Extract: The secret “bakery” aroma that makes everyone swoon before the first bite.
- Ground Cinnamon: Essential spice for that classic French toast flavor and a cozy fragrance.
- Ground Nutmeg: A warm, slightly nutty sprinkle for sophisticated depth.
- Salt: A pinch sharpens all the sweet flavors and keeps things balanced.

How to Make Best Overnight French Toast Casserole
Step 1: Prep Your Baking Dish and Bread
Begin by greasing a 9×13-inch baking dish with butter or nonstick spray. This is your insurance against sticking (and helps with cleanup). Cut your loaf of French bread into 1-inch cubes—think bite-sized, but not too small—and scatter them evenly in the dish. If your bread is on the fresh side, you can leave the cubes out for a few hours to dry a little, which really does wonders for soaking up flavor.
Step 2: Mix the Custard
In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt. Whisk until fully combined and smooth. This mix is the creamy magic that turns ordinary bread into the star of the Best Overnight French Toast Casserole.
Step 3: Soak the Bread
Next, pour the custard evenly over the bread cubes in your dish. Gently press down on the bread with a spatula or your hands to help it soak up the custard—every piece wants a turn! Cover the dish tightly with foil and refrigerate overnight, or at least 6 hours, for the ultimate flavor infusion and texture.
Step 4: Prepare the Crumbly Topping
While your casserole chills, make the topping: in a medium bowl, mix the flour, brown sugar, cinnamon, and salt. Add in the cold butter pieces and use a pastry cutter (or just your fingers) to cut the butter into the mixture until coarse, crumbly bits form. This topping adds that irresistible crunch on top of every soft, custardy bite. Store the topping in the fridge, covered, until morning.
Step 5: Bake to Golden Perfection
When you’re ready to bake, preheat your oven to 350°F (175°C). Sprinkle the chilled crumb topping gently and evenly over the soaked bread. Bake the casserole uncovered for 45–55 minutes, until golden brown and the center is set but still a little custardy. Let it cool slightly so the texture settles, then serve warm for maximum comfort and deliciousness.
How to Serve Best Overnight French Toast Casserole
Garnishes
This dish positively shines with just a few finishing touches! Classic maple syrup is a must, of course, but don’t overlook a dusting of powdered sugar for snowy elegance, or a tumble of fresh berries for a pop of color and tart freshness. If you want something extra indulgent, a spoonful of softly whipped cream never hurts.
Side Dishes
Best Overnight French Toast Casserole is hearty, so a spread of lighter sides makes for a beautiful brunch. Consider serving with crisp bacon or sausage links, a cozy bowl of fresh fruit salad, or even a tangy citrus yogurt parfait to balance the sweetness. Coffee and orange juice round out the perfect morning feast.
Creative Ways to Present
For special occasions, try baking individual servings in ramekins for a chic spin on the casserole. If you’re hosting a buffet, cut squares and serve them on a platter lined with parchment, with a “toppings station” of maple syrup, fruit, and nuts. For a fun twist, swirl in a bit of cream cheese or fruit preserves before baking—guests will ask for the secret!
Make Ahead and Storage
Storing Leftovers
Leftover Best Overnight French Toast Casserole is a true gift. Once cooled, cover the dish tightly or transfer pieces to an airtight container. Store in the refrigerator for up to 3 days. The flavors become even more delicious as they meld, and reheated leftovers make breakfast a breeze!
Freezing
If you want to stash some away for the future, you’re in luck—this casserole freezes beautifully. Wrap cooled slices or the whole bake tightly in plastic wrap, then foil, and freeze for up to 2 months. Thaw overnight in the fridge before warming back up for a nearly instant homemade brunch.
Reheating
To reheat, simply pop individual slices in the microwave for 30–60 seconds or warm larger portions, covered with foil, in a 325°F oven until hot. If you like, re-crisp the topping under the broiler for a minute or two—just keep a close eye out so it doesn’t burn!
FAQs
Can I use a different type Breakfast
Absolutely! While French bread is classic, challah or brioche will make the casserole even richer and more decadent. Just be sure to cube it the same way and use bread that’s a little bit stale to soak up the custard.
Does it have to soak overnight?
Overnight soaking gives the Best Overnight French Toast Casserole its unbeatable texture, but if you’re short on time, even 30 minutes can do in a pinch—just make sure every bread cube is soaked before baking.
Is it possible to make this dairy free?
You sure can! Swap in your favorite non-dairy milk and a plant-based cream for the custard. Use vegan butter in the topping, and check that your bread is dairy free. The casserole will still be deliciously satisfying.
How do I know when the casserole is finished baking?
The top should be golden and crisp, and the center should feel set but not dry—a little jiggle is perfect. You can insert a knife into the center; if it comes out mostly clean (a few moist crumbs are fine), you’re ready to serve.
Can I prepare the topping ahead of time, too?
Yes! Making the topping in advance is a huge time saver. Just store it covered in the refrigerator, and sprinkle it on right before baking for the crispiest finish.
