Why This is the Best Overnight French Toast Casserole Recipe
There are many recipes out there, but this one is designed for foolproof success. Here’s why it stands out:

- Completely Customizable: This recipe is a fantastic base. You can add fruits, nuts, or a streusel topping to make it your own.
Key Ingredients You’ll Need
The beauty of this dish lies in its simple, high-quality ingredients. Here’s what you’ll need to create the perfect custard base and casserole structure.
- Bread: A sturdy, slightly dry loaf of bread is the star. It needs to be robust enough to absorb the custard without turning to mush.
- Eggs: They form the foundation of the custard, giving the casserole its structure and richness.
- Dairy: A combination of whole milk and heavy cream provides the perfect balance of moisture and decadent flavor.
- Sugar: We use brown sugar for its molasses notes, which add depth and warmth to the custard.
- Flavorings: Vanilla extract, ground cinnamon, and a pinch of nutmeg are essential for that classic French toast taste.
- Butter: Melted butter is drizzled over the top before baking to help create that irresistible golden-brown crust.
The Best Bread for French Toast Casserole
The type of bread you choose is the single most important factor in a successful casserole. You need a bread with a tight crumb and sturdy structure. Softer, everyday sandwich bread will dissolve into a soggy mess.
Most importantly, your bread should be stale or day-old. Dry bread acts like a sponge, eagerly soaking up the custard. Fresh, moist bread is already saturated and won’t absorb as much, leading to a wet, dense result. If your bread is fresh, simply cube it and leave it on a baking sheet on the counter for a few hours, or bake it in a low-temperature oven (300°F/150°C) for 10-15 minutes to dry it out.
Our top choices are:
- Brioche: This is our number one pick. Its high egg and butter content gives it a rich flavor and a soft-yet-sturdy texture that’s perfect for this dish. Explore our classic brioche French toast recipe to see why we love it.
- Challah: Similar to brioche, this egg-based bread is light, airy, and soaks up custard beautifully without falling apart.
- French Bread: A crusty loaf of French bread or a baguette also works wonderfully, providing a slightly chewier texture.
How to Make Overnight French Toast Casserole
This recipe is as easy as assemble, chill, and bake. Follow these simple steps for a perfect result every time.
Step 1: Prepare the Bread
Cut your day-old bread into 1-inch cubes. Don’t worry about them being perfectly uniform. Spread the bread cubes in a single, even layer in a buttered 9×13 inch baking dish.
Step 2: Make the Custard
In a large bowl, whisk together the eggs, milk, heavy cream, brown sugar, vanilla extract, cinnamon, nutmeg, and salt. Continue whisking until the sugar is dissolved and the mixture is smooth and well-combined. You want a consistent, homogenous custard.
Step 3: Assemble and Chill
Carefully and evenly pour the custard mixture over the bread cubes in the baking dish. Gently press down on the bread with a spatula to ensure all the pieces are coated and beginning to absorb the liquid. Cover the dish tightly with plastic wrap or foil and place it in the refrigerator for at least 8 hours, or overnight. This chilling time is crucial for the bread to fully absorb the custard.
Step 4: Bake to Golden Perfection
The next morning, preheat your oven to 350°F (175°C). Remove the baking dish from the refrigerator and let it sit at room temperature for about 20-30 minutes. Uncover the dish and drizzle the melted butter evenly over the top. Bake for 45-55 minutes, or until the top is golden brown and the center is set (a knife inserted into the middle should come out clean). Let it cool for 10 minutes before serving.

Notes
Make-Ahead Tip: You can assemble the casserole and freeze it unbaked for up to 2 months. Thaw overnight in the refrigerator before baking as directed.
Tips for Preventing a Soggy Casserole
A soggy bottom is the most common pitfall of a baked French toast casserole, but it’s easily avoidable. Follow these key tips:
- Use Dry Bread: This is non-negotiable! As mentioned, stale, dry bread is far more absorbent than fresh bread.
- Don’t Over-Soak: While an overnight soak is ideal, don’t go much beyond 24 hours. The bread can start to break down too much. 8-12 hours is the sweet spot.
- Check for Doneness: Make sure the center is fully cooked. If it jiggles excessively when you nudge the pan, it needs more time. The internal temperature should be at least 170°F (77°C).
Fun Variations and Topping Ideas
While this casserole is divine on its own, it’s also a wonderful canvas for creativity. Here are a few ideas:
- Blueberry Cream Cheese: Dot the casserole with small cubes of cream cheese and a cup of fresh or frozen blueberries before baking. It’s a flavor combination you’ll love, similar to our popular blueberry french toast casserole (coming soon).
- Cinnamon Streusel Topping: Before baking, sprinkle a mixture of 1/2 cup flour, 1/2 cup brown sugar, 1 teaspoon cinnamon, and 1/4 cup cold, cubed butter over the top for a crunchy, sweet crust.
- Fall Flavors: Add 1/2 cup of pumpkin puree to the custard and a dash of pumpkin pie spice for a seasonal twist.
- Classic Toppings: Serve slices warm with a dusting of powdered sugar, a drizzle of maple syrup, fresh berries, or a dollop of whipped cream.
How to Store, Reheat, and Freeze
This recipe is perfect for making ahead and enjoying later. Here’s how to handle leftovers:
Storing Leftovers
Cover the baking dish tightly with foil or transfer individual slices to an airtight container. Store in the refrigerator for up to 3 days.
Reheating
For best results, reheat individual slices in the microwave for 45-60 seconds or in an oven or toaster oven at 350°F (175°C) for 10-15 minutes until warmed through. The oven method will help re-crisp the top.
Freezing (Baked and Unbaked)
Yes, you can freeze this casserole!
- To Freeze Unbaked: Assemble the casserole as directed, but cover it with a layer of plastic wrap followed by a layer of foil. Freeze for up to 2 months. Thaw it in the refrigerator overnight before baking as directed. You may need to add 10-15 minutes to the baking time.
- To Freeze Baked: Let the casserole cool completely. You can freeze the entire dish or individual portions. Wrap tightly in plastic wrap and foil and freeze for up to 3 months. Thaw in the fridge and reheat.
Frequently Asked Questions
While the overnight chill is highly recommended for the best texture and flavor, you can make a quicker version. Let the casserole soak for a minimum of 2-4 hours in the refrigerator before baking. The texture may be slightly less uniform, but it will still be delicious.
The casserole is done when the top is golden brown and puffed, and the center is set. When you gently shake the pan, it should not jiggle. For a precise check, a knife inserted into the center should come out clean, or an instant-read thermometer should register at least 170°F (77°C).
Rich, sturdy breads like brioche and challah are the best choices because their high egg and butter content allows them to soak up the custard while still holding their shape. A crusty French loaf also works well. Avoid standard soft sandwich bread.
The most common cause of a soggy casserole is using bread that is too fresh and moist. It’s essential to use stale, day-old, or lightly toasted bread cubes, as they are much more absorbent and will soak up the custard properly without turning to mush.
