How to Make Overnight Brioche French Toast Casserole
Phase 1 – Prep
STEP 1. Combine ingredients. In a large bowl, whisk together the oat milk, eggs, maple syrup, vanilla extract, and ground cinnamon until well blended.
STEP 2. Prepare bread. Place the cubed brioche bread into a greased baking dish and pour the egg mixture over the bread, ensuring it soaks evenly.
STEP 3. Cover and refrigerate. Seal the dish with plastic wrap and place it in the refrigerator overnight to allow the bread to absorb the custard.
Phase 2 – Cook
STEP 4. Preheat your oven. The next day, preheat your oven to a suitable temperature.
STEP 5. Prepare topping. In a small bowl, mix together the flour, coconut sugar, and additional ground cinnamon. Add the cubed butter and mix until crumbly.
STEP 6. Top the casserole. Remove the dish from the refrigerator, sprinkle the prepared topping over the soaked bread, and gently press down.
STEP 7. Bake the casserole. Place in the oven and bake until puffed and golden brown.
Phase 3 – Serve
STEP 8. Cool slightly. Let the casserole cool for a few minutes before serving.
STEP 9. Add toppings. Serve warm, optionally topped with fresh berries, maple syrup, or powdered sugar for added sweetness.
Why This Recipe Works
The secret to the casserole’s delightful texture lies in the balance between the soft brioche and the creamy custard, leading to a beautifully tender outcome. As the dish bakes, the heat transforms the eggs and milk into an airy masterpiece that contrasts perfectly with the topping. Each ingredient works in harmony: the natural sweetness of the maple syrup complements the richness of the brioche, while the warmth of cinnamon ties it all together. This combination not only elevates the flavor but also provides a comforting, indulgent experience that is perfect for indulging on special mornings.
Pro Tips
1. Use stale brioche: A day or two-old brioche soaks up the custard without becoming mushy.
2. Adjust sweeteners: Feel free to customize the level of sweetness by adjusting maple syrup or using your favorite sweetener.
3. Let it chill properly: Giving the casserole ample time in the fridge allows for maximum absorption of the custard.
4. Serve warm: This dish is best enjoyed warm for the ultimate taste experience.
5. Experiment with toppings: Try adding nuts, chocolate chips, or different fruits for variety.
Common Mistakes to Avoid

Why it happens: Fresh bread can become too mushy during baking.
How to fix it: Allow the bread to sit out for a day or lightly toast it before preparing.

How to fix it: Ensure the casserole sits in the fridge overnight for optimal flavor and texture.
Mistake: Overbaking the casserole.
