Ingredients You’ll Need
Believe it or not, the magic in this casserole lies in its simplicity. Each ingredient plays a crucial role in building the perfect balance of creamy custard-soaked bread, warm spices, and a sweet, crunchy topping that makes every bite irresistible.
- French bread (1 loaf, approx. 12 cups cubed, day-old preferred): Using day-old bread helps it absorb the custard without turning mushy, providing wonderful texture.
- Large eggs (8): These bind the custard and give the casserole that rich, custardy structure you’re aiming for.
- Whole milk (2 cups): Adds creaminess and balances the flavors with a smooth finish.
- Heavy cream (1 cup): Infuses the dish with luxurious richness and a velvety mouthfeel.
- Granulated sugar (1/2 cup): Sweetens the custard delicately without overpowering the spices.
- Vanilla extract (1 tbsp): Adds warmth and depth, elevating the overall flavor.
- Ground cinnamon (1 tsp): The perfect spice to evoke cozy mornings and complement the sweetness.
- Salt (1/4 tsp): Enhances all the other flavors and balances the sweetness.
- Ground nutmeg (1/4 tsp, optional): A subtle spicy note that adds extra warmth if you like a little more complexity.
- Unsalted butter (1/2 cup, melted): Combines with brown sugar to form a luscious topping with a hint of richness.
- Brown sugar (1/4 cup, packed): Brings caramelized sweetness to the topping, giving the crust a delightful crunch.
- Ground cinnamon (1/2 tsp, for topping): Sprinkled in the topping to create a sweet-spiced finish.
- Pinch of salt (for topping): Balances the topping and intensifies flavors.
- Chopped pecans or walnuts (1/4 cup, optional): Adds a wonderful nutty crunch that contrasts beautifully with the soft bread.
How to Make Best Overnight French Toast Casserole Recipe
Step 1: Prepare the Casserole Base
Grease a 9×13-inch baking dish thoroughly to stop your casserole from sticking during baking. Then, cut your French bread into cubes—about 12 cups worth. Day-old bread is ideal because it soaks up the custard wonderfully without turning mushy. Spread the bread cubes evenly in your baking dish, setting the stage for that beautiful custard soak.
Step 2: Whisk the Custard Mixture
In a large mixing bowl, vigorously whisk together 8 large eggs, 2 cups whole milk, 1 cup heavy cream, 1/2 cup granulated sugar, 1 tbsp vanilla extract, 1 tsp ground cinnamon, 1/4 tsp salt, and an optional 1/4 tsp ground nutmeg if you want a touch more spice. This custard is the heart of your casserole, providing moisture and rich flavor that will absorb into every bread cube.
Step 3: Combine Bread and Custard
Pour your custard mixture evenly over the bread cubes, ensuring each piece is coated. Press down lightly on the bread so it soaks up as much custard as possible. Cover the dish with plastic wrap or foil and pop it into the refrigerator for at least four hours, but overnight is best. This slow soak allows the bread to fully absorb flavors, making the crisped up result divine.
Step 4: Prepare the Sweet Topping
Before baking, mix together 1/2 cup melted unsalted butter, 1/4 cup packed brown sugar, 1/2 tsp ground cinnamon, and a pinch of salt until smooth. This topping is pure gold—it melts into the casserole as it bakes, giving you a sweet, caramelized crust that’s hard to resist.
Step 5: Bake to Perfection
Preheat your oven to 350°F (175°C). Drizzle the topping evenly over your soaked bread cubes, and sprinkle chopped pecans or walnuts on top if using. Bake uncovered for 45 to 50 minutes until the top turns a gorgeous golden brown and the center is fully set. Your kitchen will be filled with the most amazing aroma—you’re almost there!
Step 6: Rest and Serve
Once out of the oven, let the casserole rest for about five minutes before slicing. This brief rest time lets it set up perfectly, making it easier to serve. Pair with maple syrup, powdered sugar, or fresh berries to make it truly unforgettable.

Garnishes
The right garnish takes your casserole from delicious to dazzling. A generous dusting of powdered sugar adds a snowy sweetness, while fresh berries bring brightness and color to the plate. Don’t forget a drizzle of warm maple syrup, which elevates this dish into a decadent breakfast treat.
Side Dishes
Pair your casserole with simple yet complementary sides like crisp bacon for a salty contrast, or fresh fruit salad for a light, refreshing balance. A dollop of whipped cream or a scoop of vanilla yogurt on the side can also add creamy coolness that pairs perfectly with the warm cassserole.
Creative Ways to Present
If you’re serving guests or want to make breakfast extra special, try layering your casserole in individual ramekins or mini cast iron skillets—this not only looks charming but helps with portion control. Alternatively, serve slices on rustic wooden boards topped with garnishes and a sprinkling of nuts for a cozy brunch vibe everyone will love.
Make Ahead and Storage
Storing Leftovers
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. The flavors deepen as it sits, making for delicious next-day breakfasts or snacks. Reheat gently to preserve the moist texture without drying it out.
Freezing
This casserole freezes beautifully! After baking and cooling completely, wrap it tightly with plastic wrap and aluminum foil, or place portions into freezer-safe containers. Freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge before reheating.
Reheating
For best results, reheat individual slices in a 350°F oven for about 10-15 minutes until warmed through and slightly crisp around the edges. Microwaving works in a pinch but can make the casserole a bit soggy, so the oven is the way to go to keep that perfect texture.
FAQs
Can I use a different type of bread?
Absolutely! While French bread is ideal for its firm texture and crumb, you can experiment with challah or brioche for an even richer flavor. Just make sure the bread is sturdy enough to hold the custard without falling apart.
Can I make this casserole dairy-free?
Yes! Substitute the whole milk and heavy cream with your favorite plant-based milks such as almond, oat, or coconut milk. Use a dairy-free butter alternative for the topping, and you’ll still get a delicious and creamy casserole.
How long can I soak the bread overnight?
You can soak the bread for anywhere from 4 to 12 hours. The longer it soaks, the more tender and custardy the casserole will be, but over-soaking beyond 12 hours might make the texture too soggy.
Is it okay to skip the nuts on top?
Yes, the nuts are optional and can be omitted if you prefer. They add a lovely crunch and flavor contrast, but the casserole is fabulous on its own without them.
Can I prepare this casserole in advance for a party?
Definitely! This dish is perfect for entertaining since you can assemble it a day ahead, refrigerate it overnight, and bake it fresh in the morning or right before guests arrive—minimal hands-on time with maximum wow factor.
