Ingredients
To whip up your own delicious Overnight French Toast Casserole, gather the following ingredients:
- 1 pound loaf of brioche, challah, french bread, or white bread (choose your favorite!)
- 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
- For the topping: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

Ingredient Notes and Easy Substitutions
- Bread Choice: While brioche and challah are excellent for their soft texture and sweetness, French bread offers a nice crusty option. Feel free to use whatever you have on hand, but avoid very airy or dry bread, which may result in a too-soggy casserole.
- Milk and Cream Options: For a lighter version, you can replace heavy cream with half-and-half or whole milk. Non-dairy alternatives such as almond milk or coconut milk can also be used, but check their flavors to ensure they match your preference.
- Sugar Variations: Brown sugar can be swapped for coconut sugar or honey, but be mindful how these might alter the taste.
Instructions
- Prep the Dish: Grease a 9×13 inch baking dish generously to ensure easy removal after baking.
- Cut the Bread: Slice your chosen bread into 1-inch chunks and place them evenly in the prepared pan.
- Create the Custard Mixture: In a large mixing bowl, whisk together the eggs. Then add the heavy cream, milk, light brown sugar, 2 teaspoons of cinnamon, kosher salt, and vanilla extract, mixing until everything is well combined.
- Combine with Bread: Pour the custard mixture evenly over the bread cubes. Gently toss the bread to ensure all pieces are soaked in the mixture, then spread it into an even layer in the pan.
- Refrigerate: Cover the pan with plastic wrap and refrigerate overnight, allowing the bread to absorb the custard mixture fully.
- Prepare the Topping: For the topping, combine the brown sugar, granulated sugar, cinnamon, and nutmeg in a bowl. Add cold butter pieces, and use a pastry blender or your fingers to mix until the texture is crumbly. Cover and refrigerate until the casserole is ready to bake.
- Bake: Preheat your oven to 350ยฐF (180ยฐC). Remove the plastic wrap from the casserole and sprinkle the topping evenly over the bread mixture.
- Cook to Perfection: Bake for 45-50 minutes, or until the top is golden and the casserole is set in the middle. It should look puffed and slightly firm, with a nice crust on top.
- Cool and Serve: Allow the French toast casserole to cool for at least 10 minutes before serving. Top with your favorite syrup, fresh berries, whipped cream, or a dusting of powdered sugar.
Expert Tips for the Best Results
- Stale Bread Advantage: If you have leftover stale bread, this is the perfect time to use it! Stale bread holds up better against the custard and creates the best texture.
- Donโt Rush the Soaking: Ensure that you refrigerate the casserole overnight. This step is crucial for the bread to soak up the custard mixture thoroughly.
- Test for Doneness: If unsure, insert a knife in the center; it should come out clean when the casserole is done.
Variations
- Berry Delight: Add fresh or frozen berries like blueberries, strawberries, or raspberries mixed within the bread before baking for a fruity twist.
- Nutty Banana: Incorporate slices of banana and sprinkle chopped walnuts or pecans into the mixture for a nutty flavor.
- Chocolate Loverโs: Add chocolate chips or chunks into the bread mixture for an extra sweet treat.
- Maple Pecan: Mix in maple syrup in place of some of the sugar and add chopped pecans for a decadent version.
- Savory Spin: For something different, consider adding cooked bacon or sausage and a dash of cheese, transforming the dish into a hearty breakfast.
Serving Suggestions
When it comes to serving your Overnight French Toast Casserole, think beyond just a drizzle of syrup. Here are some delicious ideas to complement your dish:
- Fresh Fruit: Serve with seasonal berries, sliced bananas, or a warm fruit compote on the side.
- Creamy Toppings: Add whipped cream, crรจme fraรฎche, or Greek yogurt for added creaminess.
- Nuts: Toasted nuts can add a delightful crunch and flavor contrast to the soft casserole.
- Drinks: Pair it with fresh orange juice, coffee, or mimosas for a complete breakfast experience.
Storage and Reheating
If you happen to have leftovers (which is rare!), store them in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm the casserole in the oven at 350ยฐF (175ยฐC) for about 15 minutes or until heated through. You can also microwave individual portions for a quick breakfast.
