How to Make Brioche French Toast Casserole
Step 1: Prep Your Baking Dish and Brioche
Begin by greasing a 9×13-inch baking dish with butter or nonstick spray. Scatter the brioche cubes evenly in the dish. Using fresh or day-old brioche works beautifully—the bread needs to be sturdy enough to hold its shape while absorbing that rich custard. The golden edges of brioche will toast up beautifully, giving you those deliciously crisp corners.
Step 2: Whisk the Custard Mixture
In a large bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, and salt. Take a moment to whisk until everything’s beautifully combined, with no streaks of unbeaten egg. This custard is the magic that gives Brioche French Toast Casserole its luxurious, melt-in-your-mouth texture—make sure it’s perfectly smooth for best results.
Step 3: Assemble and Soak the Casserole
Pour the custard mixture evenly over the brioche cubes, pressing down gently with a spatula or the back of a spoon to help the bread soak up all that goodness. You want every piece of brioche to be touched by the custard. Cover the dish with foil or plastic wrap and refrigerate overnight, or for at least 30 minutes if you’re short on time. That soak is what transforms the casserole, letting every cube become rich, soft, and custardy through and through.
Step 4: Drizzle with Butter and Bake
Preheat your oven to 350°F (175°C). Uncover the casserole and drizzle the melted unsalted butter over the top. This step is key—it helps the top bake to a golden, irresistibly crisp finish while the inside stays custardy and tender. Bake for 35 to 40 minutes, until the casserole is set and lightly puffed, and the top is gorgeously golden.
Step 5: Serve with Your Favorite Toppings
Remove the Brioche French Toast Casserole from the oven and let it cool for a few minutes. Dust generously with powdered sugar and drizzle with warm maple syrup just before serving. The contrast of the crisp, golden top and the soft, custardy inside is pure breakfast bliss!
How to Serve Brioche French Toast Casserole
Garnishes
Give your Brioche French Toast Casserole that final flourish with a generous sprinkle of powdered sugar and a decadent pour of pure maple syrup. If you’re feeling fancy, a handful of fresh berries or a dollop of whipped cream will make every bite feel extra special. The tender, custardy bread meets the sweetness of the toppings in perfect harmony.
Side Dishes
For a brunch spread that’s truly memorable, serve your casserole alongside crisp bacon or savory breakfast sausage for a contrast of flavors. A big fruit salad or a simple bowl of sliced strawberries and bananas adds a burst of color and freshness that balances the richness wonderfully.

For a touch of elegance, finish each portion with a twist of orange zest or a sprinkle of chopped toasted nuts.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, simply cover the baking dish tightly with foil or transfer the casserole to an airtight container. Keep it in the refrigerator for up to three days. The flavors get even better as the custard settles in!
Freezing
Yes, you can freeze Brioche French Toast Casserole! After baking and cooling, wrap individual portions or the whole pan tightly in plastic wrap and then foil. Freeze for up to two months. When you’re ready to enjoy, just thaw overnight in the fridge and reheat.
Reheating
To bring back the magic, reheat slices in the microwave for 30 seconds at a time until warmed, or for the best texture, pop them into a 325°F oven for 10-15 minutes. You’ll get those lovely golden edges and a warm, custardy center—just like fresh!
FAQs
Can I assemble Brioche French Toast Casserole the night before?
Absolutely! In fact, letting the casserole soak overnight in the fridge only makes it better. The bread absorbs all the custard, ensuring a soft, flavorful center and crisp golden top when baked.
Can I use a different type of bread?
While brioche is the star here, you can substitute challah or a good quality French bread if needed. Just make sure the bread is a bit sturdy so it can handle the rich custard.
Is it possible to make Brioche French Toast Casserole dairy free?
Yes! Swap the milk and cream for full-fat coconut milk or your favorite plant-based alternatives, and use a plant-based butter. The results will still be rich and delicious.
How do I know when the casserole is done baking?
The casserole should be puffed and golden, and when you gently push the center it should feel set—not too jiggly. A knife inserted in the center should come out clean or with just moist crumbs attached.
What toppings go best with Brioche French Toast Casserole?
Besides powdered sugar and maple syrup, try fresh berries, caramelized bananas, or a drizzle of warmed berry compote. Even a spoonful of Greek yogurt on top is a wonderful touch.
