How to Make Overnight Brioche French Toast Casserole
Prepare the Baking Dish: Spray a 13×9 glass pan with cooking spray, then evenly distribute the cubed brioche bread throughout the pan. Set it aside while you work on the custard.
Mix the Custard: In a medium-sized bowl, whisk together brown sugar, cinnamon, nutmeg, and salt. Stir in the melted butter, then add the eggs, milk, heavy cream, and vanilla extract. Whisk until smooth without any visible egg yolks, and pour this heavenly mixture over the cubed bread.
Toss the Bread: Gently toss the cubed bread using a rubber spatula or your hands to ensure most pieces are coated in the egg mixture. Be careful not to overmix, as you want to keep the bread intact.
Refrigerate: Cover the 13×9 glass pan with plastic wrap and refrigerate overnight, or for a minimum of 3 hours. This allows the bread to soak up all those luscious flavors.
Make the Crumble Topping: In a small bowl, combine the flour, brown sugar, oats, cinnamon, and salt. Add the cold, cubed butter and stir until coated. Use your hands to blend everything until the mixture becomes dough-like. Cover and refrigerate until you’re ready to bake.
Preheat and Assemble: Preheat your oven to 350°F. Remove the casserole and topping from the refrigerator. Break up the crumble topping into small pieces and evenly spread it over the top of the casserole.
Bake to Perfection: Place the casserole in the oven and bake for about 45-60 minutes, or until the crumble topping turns golden brown and crispy.
Optional: Drizzle with maple syrup or add fresh berries before serving for an irresistible touch.

Overnight Brioche French Toast Casserole Recipe FAQs
What type of brioche bread should I use?
You’ll want to use a fresh, high-quality brioche for the best results. Look for a loaf that feels soft, with a slightly sweet aroma. Avoid stale or dry bread, as it won’t absorb the custard like fresh bread does, leaving you with a less delectable casserole.
How should I store the Overnight Brioche French Toast Casserole?
Once cooled completely, store any leftovers in an airtight container in the fridge for up to 3 days. For best results, reheat individual portions in the microwave or warm them in the oven at 350°F until they’re heated through and ready to enjoy.
Can I freeze the casserole after baking?
Absolutely! You can freeze your Overnight Brioche French Toast Casserole for up to 2 months. Just make sure it has cooled entirely, then wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn.
What’s the best way to reheat a frozen casserole?
To reheat from frozen, simply transfer it to the fridge to thaw overnight. When you’re ready to serve, preheat your oven to 350°F and bake for about 20-30 minutes until it’s warmed throughout. You may want to cover it with foil for the first half to ensure even warming.
What if my casserole is too soggy?
If your casserole comes out soggy, it may have soaked for too long or too much custard was added. For future batches, try reducing the soaking time to about 3-4 hours instead of overnight, or use less liquid to achieve the texture you prefer.
Are there any dietary considerations I should keep in mind?
Yes, definitely! If anyone in your family has a dairy allergy, consider using dairy-free milk and butter alternatives. Also, remember that this recipe contains eggs, so it’s not suitable for vegans. For those with gluten sensitivities, a gluten-free bread variant can also work, making it adaptable for everyone at the table.
