Kitchen Equipment Needed
To make this Overnight French Toast Casserole, you’ll need:
- Large mixing bowl
- Whisk
- 9×13-inch baking dish
- Aluminum foil (for covering)
- Spatula
How to Make Overnight French Toast Casserole
1. Prep the Bread and Dish
Butter a 9×13-inch baking dish generously to prevent sticking. Arrange the sliced French bread in overlapping layers.
2. Make the Custard
In a large bowl, whisk together the eggs, half-and-half, milk, sugar, vanilla extract, cinnamon, and nutmeg until smooth and fully combined.
3. Combine Bread and Custard
Pour the custard mixture evenly over the bread slices, ensuring every piece is soaked. Gently press down with a spatula to help the bread absorb the custard.
4. Refrigerate Overnight
Cover the dish with aluminum foil and refrigerate overnight (or at least 6 hours). This step allows the bread to fully absorb the custard for a soft, custardy center.
5. Bake to Perfection
Preheat your oven to 350°F (175°C). Bake the casserole, covered with foil, for 25–30 minutes. Remove the foil and bake an additional 10–15 minutes, or until the top is golden and slightly crisp.
6. Add the Caramelized Topping
Sprinkle a generous layer of sugar over the top of the baked casserole. Broil for 1–2 minutes until the sugar caramelizes and forms a crispy crust.
7. Serve and Enjoy
Slice into portions and serve warm with a drizzle of maple syrup.
Serving and Storage Tips
- Serving: Pair with fresh fruit or a dusting of powdered sugar for an elegant touch.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Warm individual portions in the microwave or oven to maintain the crispy top.
Variations and Substitutions
This Overnight French Toast Casserole is wonderfully versatile. Here are some ideas to customize it:
- Fruit addition: Add fresh berries, sliced apples, or banana slices between the bread layers for a fruity twist.
- Nut topping: Sprinkle chopped pecans or almonds over the sugar before broiling for extra crunch.
- Spiced flair: Increase the cinnamon and nutmeg or add a pinch of ground ginger or cardamom for a spiced flavor profile.
Helpful Notes
- Crispy topping tip: Keep a close eye when broiling the sugar—it can burn quickly!
- Stale bread is best: Slightly dry bread absorbs the custard better, so use day-old bread if possible.
- Crowd-ready: Double the recipe and use two baking dishes to serve a larger group.

- Joanna Gaines: “Let the bread soak overnight for a truly custardy and luxurious texture.”
- Martha Stewart: “For a hint of elegance, add a splash of orange juice or zest to the custard mixture.”
