A Brief History of French Toast
French toast, known as “pain perdu” in France, has been a popular dish for centuries. Originally created as a way to use up stale bread, it has evolved into a beloved breakfast staple worldwide. This casserole version takes the traditional French toast to a new level by baking it with a custardy filling and a crispy, caramelized topping.

Ingredients for Brioche French Toast Casserole
Essential Ingredients
To make this indulgent casserole, you’ll need a few essential ingredients. Start with a loaf of brioche bread, known for its buttery and soft texture. You’ll also need eggs, milk, heavy cream, sugar, vanilla extract, and a generous amount of cinnamon to create the rich custard base.
Optional Add-ins
To customize your casserole, consider adding some optional ingredients like fresh berries, nuts, or chocolate chips. These add-ins provide extra flavor and texture, making each bite a delightful surprise.
Substitutions and Variations
If you don’t have brioche on hand, substitute with challah or any soft white bread. For a dairy-free option, use almond milk and coconut cream. Feel free to adjust the sweetness by using maple syrup or honey instead of sugar.
Step-by-Step Instructions
Preparing the Brioche
Begin by slicing the brioche into thick pieces. It’s best if the bread is slightly stale, as it will absorb the custard more effectively. Arrange the slices in a greased baking dish, overlapping them slightly.
Mixing the Custard
In a large mixing bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, and cinnamon until well combined. This custard mixture will soak into the bread, giving it a creamy texture and rich flavor.
Assembling the Casserole
Pour the custard mixture evenly over the brioche slices, ensuring each piece is well coated. For an overnight option, cover the dish with plastic wrap and refrigerate it for at least 4 hours or overnight.
Baking and Serving Tips
Preheat your oven to 350°F. Remove the dish from the refrigerator and let it sit at room temperature for 30 minutes before baking. Bake for 45-50 minutes until the top is golden brown and the custard is set. Serve warm with a drizzle of maple syrup or a dusting of powdered sugar.

Pro Tips
Making the perfect Brioche French Toast Casserole involves a few key steps to ensure success.
- Choosing the Right Brioche: Opt for a high-quality brioche that is slightly stale for the best absorption of the custard.
- Achieving the Perfect Texture: Allow the bread to soak in the custard overnight for a soft and creamy interior.
- Make-Ahead and Storage Tips: Prepare the casserole the night before and refrigerate it. Leftovers can be stored in an airtight container for up to 3 days.
- Enhance with Flavors: Experiment with spices like nutmeg or cardamom to add a unique twist to your casserole.
One of the most important tips is to ensure your bread has absorbed enough custard before baking. This will guarantee a moist and flavorful casserole.
