In other words, it has to be quick — and grab-and-go is always a plus.

How To Make Brioche French Toast Casserole

A full printable version of this recipe with ingredient measurements is available at the bottom of this post.

STEP ONE: Prep your 3-quart baking dish. Apply non-stick spray or butter all over so nothing sticks, and set aside. Then, cut up the bread into cubes and distribute them evenly in the pan.

STEP TWO: Place the eggs, heavy cream, milk, granulated sugar, vanilla, cinnamon, nutmeg, and salt in a large mixing bowl and whisk to combine.

STEP THREE: Pour the mixture over the bread and press down to make sure that every piece is evenly soaked. Cover the baking dish tightly with plastic wrap and place it in the fridge to chill for at least 8 hours.

That said, if you want to achieve the best brioche French casserole flavor, leave it overnight! 

STEP FOUR: When you’re ready to bake, preheat your oven to 350 degrees F. Remove the plastic wrap from the pan and place it inside the oven.

STEP FIVE: Bake your casserole for 45-60 minutes, or until it turns golden brown and is baked all the way through.

Serve with your favorite toppings — butter, maple syrup, fresh fruit, or whipped cream are just a few ideas!

Why Is My Brioche French Toast Casserole Soggy?

Be careful to follow the instructions above and on the recipe card below carefully. If you end up with soggy results, it’s likely because you used too much of the egg mixture.

You need to make sure not to over-soak the bread in order to make the best french toast casserole possible.

What Goes With Brioche French Toast Casserole?

As mentioned, you can serve this French toast casserole with maple syrup, butter, fruit, or even whipped cream!

If you want to pair it with a few savory sides for the ultimate weekend brunch, I suggest sautéed mushrooms, bacon, or scrambled eggs.

Does French Toast Casserole Need To Be Refrigerated?

If you have any leftovers, you can store them in an airtight container in the fridge, where they will keep for up to 3 days. Reheat them in the oven or simply in the microwave. 

What Bread Is Best For French Toast?

You can technically make French toast with any type of bread, but I swear by brioche.

It’s sweeter and fluffier than other varieties, and it truly makes for the best French toast casserole ever! Some other options would be challah or a day-old baguette!

  1. Hello. I can’t wait to make this. Questions:
    Can I prep this on a Friday night (Saturday we will be out all day) and keep in fridge for Sunday morning baking? Also, could I add blueberries before baking?

    • Hi Stephanie, I have let the casserole soak that long in the fridge uncooked, but can see the brioche getting too mushy. And yes, you can add blueberries!
