🥖 Ingredients You’ll Need:
1 loaf of day-old French bread (or brioche), cubed
8 large eggs
2 ½ cups whole milk
½ cup heavy cream
¾ cup granulated sugar
¼ cup brown sugar
2 tsp pure vanilla extract
1 ½ tsp ground cinnamon
¼ tsp ground nutmeg
½ tsp salt
For the Streusel Topping:
½ cup all-purpose flour
½ cup packed brown sugar
1 tsp cinnamon
¼ tsp salt
½ cup cold unsalted butter, cubed
🥣 How to Make Overnight French Toast Casserole:
Step 1: Prepare the Bread
Cut your French bread into 1-inch cubes and spread them evenly in a greased 9×13-inch baking dish. Stale or day-old bread works best because it soaks up the custard without turning soggy.
Step 2: Make the Custard
In a large bowl, whisk together the eggs, milk, cream, granulated sugar, brown sugar, vanilla, cinnamon, nutmeg, and salt. Pour the mixture evenly over the bread, pressing down lightly to ensure every piece is soaked.
Step 3: Chill Overnight
Cover the dish tightly with foil or plastic wrap and refrigerate overnight (at least 8 hours). This allows the bread to absorb all the flavors and moisture.
Step 4: Make the Streusel Topping
In a medium bowl, combine flour, brown sugar, cinnamon, and salt. Cut in the cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs. Store covered in the fridge until morning.
Step 5: Bake and Enjoy!
The next morning, preheat your oven to 350°F (175°C). Sprinkle the streusel evenly over the casserole. Bake uncovered for 45–55 minutes, or until golden brown and cooked through. Let it rest for 10 minutes before serving.

🙋♀️ FAQ: Overnight French Toast Casserole
Q: Can I use a different type of bread?
A: Yes! Brioche, challah, or Texas toast work beautifully. Softer breads may result in a more custardy texture.
Q: Do I have to chill it overnight?
A: Chilling it overnight allows the bread to absorb the custard fully. However, if you’re in a pinch, let it soak for at least 30–60 minutes before baking.
Q: Can I make this dairy-free?
A: Absolutely. Substitute almond milk or oat milk and use a dairy-free butter for the streusel. The texture may change slightly but it’ll still be delicious.
Q: How do I know it’s fully cooked?
A: The casserole should be puffed and golden. A knife inserted into the center should come out clean. If it’s still wet, bake for an additional 5–10 minutes.
Q: Can I add fruit or nuts?
A: Definitely! Blueberries, sliced apples, or chopped pecans make great additions. Add them between the bread cubes or sprinkle on top before baking.
