    The best brunches are the ones that don’t require a ton of effort in the morning, but still deliver on flavor. My kids love helping me prepare this dish the night before, and when we bake it the next morning, the kitchen is filled with the intoxicating aromas of custardy cinnamon and sugar. YUM! This will be your family’s new favorite brunch dish, baked to a golden perfection with crunchy edges, and topped with toasted pecans.

    • Overnight Brioche French Toast Casserole

    Ingredients & notes

    Ingredients for french toast casserole.

    Brioche bread – I’m using pre-sliced bread, but if you can find a brioche loaf, that’ll work great as well.

    Eggs and milk – For the custard base 

    Brown sugar and butter – Adds a hint of caramel-y flavor and richness to the custard.

    Cinnamon – A touch of this adds a wonderful aroma and warm sweetness to the dish. 

    Vanilla extract – You can also substitute with almond extract. 

    Pecans – These are optional, but I love the nuttiness and crunchy texture they add.

    Instructions

    Steps on how to make french toast casserole.

    1). Cut or roughly shred the brioche into 1-2 inch pieces.

    2). In a large mixing bowl, add the ingredients for the custard. 

    3). Add the bread into the mixing bowl, quickly mix everything together, then add it to a greased casserole dish (9 x 9” or 12 x 9” oblong). Let the bread soak up all the delicious custard mixture overnight in the fridge. 

    4). When ready to bake, preheat the oven to 350 and set the casserole out to warm up.  Add the pecans on top and bake for 55 to 60 minutes or until the custard is set.

    Let the French toast casserole sit for 10-15 minutes, then serve with optional berries and maple syrup. For special occasions, go all out for brunch with my spinach quiche, yogurt, and crispy roasted potatoes recipe!

    Pro Tips

    • This casserole is mildly sweet. If you prefer more sweetness, use ½ cup of sugar. 
    • For the final touches, sprinkle the top with cinnamon and powdered sugar when done baking.
    • The casserole is best made ahead of time, preferably overnight, so the custard and flavors can soak into the bread. 
    • To reheat leftovers: bake in a preheated oven at 350 degrees Fahrenheit until warmed through, about 15 minutes. Or bake in the toaster oven at 350 degrees Fahrenheit for 10 minutes.

    Frequently Asked Questions

    Why is my baked French toast casserole soggy?


    This can be a result of an undercooked casserole. If the casserole still “jiggles” when you take it out of the oven, bake it for an additional 10 to 15 minutes. Also, let the custard set and cool down after baking.

    What goes good with french toast casserole? 

    Fresh assorted berries like strawberries, blueberries and blackberries, then add a drizzle of maple syrup.

    Is French toast casserole supposed to be soft in the middle?

    French toast usually has a brown golden crust and is slightly soft in the middle from the egg mixture, so this recipe mimics that consistency. If you like it on the drier side, use less egg.
