Ingredients & Why They Work

Every ingredient in this Brioche French Toast Casserole Recipe plays a specific role to make it irresistibly delicious. The brioche’s richness pairs perfectly with the citrusy orange flavor and vanilla, while the sugar and coarse demerara topping lend just the right amount of sweetness and crunch.

• Brioche bread: Its high butter content means extra tenderness and flavor; I always use day-old bread so it holds up well in the custard.
• Eggs: They bind the custard together and give the casserole that classic French toast richness.
• Light brown sugar: Adds a subtle caramel undertone that complements the orange zest beautifully.
• Orange zest and juice: Provide a natural citrus brightness that keeps the dish from feeling too heavy or sweet.
• Vanilla extract: Deepens the flavor and balances the citrus notes.
• Fine salt: A small pinch to enhance every other flavor (don’t skip this).
• Milk: Keeps the custard creamy and tender without overwhelming the eggs.
• Butter: For greasing the dish and adding extra richness to the bake.
• Coarse sugar (demerara): Sprinkled on top before baking, this makes for a delightful, crunchy crust.

Make It Your Way

What I really love about this Brioche French Toast Casserole Recipe is how easy it is to make your own. You can tweak it to your taste buds or dietary needs and still end up with a crowd-pleaser. Don’t be shy about customizing it with your favorite flavors or add-ins.

• Variation: I sometimes add a sprinkle of cinnamon or nutmeg to the custard for an extra cozy vibe—it brings warmth without overpowering the orange notes.
• Dairy-free option: Swap the milk for a rich almond or oat milk, and use a plant-based butter for greasing the dish.
• Adding fruit: Fresh berries or sliced apples layered in the casserole add bursts of brightness and color. I’ve found frozen berries work great if fresh aren’t in season.
• Sweeteners: If you want things a little lighter, try using maple syrup or honey in the custard instead of brown sugar.

Step-by-Step: How I Make Brioche French Toast Casserole Recipe

Step 1: Preparing the Bread Just Right

Start by slicing your brioche loaf into thick 1.5 cm slices to ensure they absorb the custard perfectly without falling apart. I usually cut each slice diagonally into triangles, which makes for charming serving and helps them soak evenly. One key tip I’ve learned: using day-old brioche works wonders because fresh bread can get mushy fast when soaked.

Step 2: Whisking Up the Custard

In a medium bowl, whisk together the eggs, light brown sugar, orange zest and juice, vanilla, salt, and milk. I find using freshly zested orange zest lifts the custard’s aroma — it really brightens the whole dish. Make sure to whisk until it’s fully combined and smooth so the flavors meld beautifully.

Step 3: Butter Up and Soak

Butter a 9×13 inch casserole dish thoroughly, covering the base and sides. You’ll likely have some butter left — dollop it around the pan for extra flavor pockets during baking. Then, dunk each bread triangle fully into the custard, ensuring it’s soaked, and neatly arrange them upright in the dish with the pointed ends facing up. Pour any remaining custard over the top, cover, and let it rest at room temperature for 30 minutes to soak up all those lovely flavors.

Step 4: Bake to Golden Perfection

Before baking, sprinkle the coarse demerara sugar over the top — this will give you a satisfying caramelized crunch. Bake in a preheated oven at 165°C (340°F) for about 25–30 minutes, until it’s puffed up and lightly golden. I like to let it rest for 10 minutes after baking so the casserole sets nicely and is easier to cut without squishing.

How to Serve Brioche French Toast Casserole Recipe

Garnishes

I’m a big fan of keeping garnishes simple but flavorful. Fresh berries—like raspberries or blueberries—add a pop of color and tartness that cuts through the richness. A dusting of powdered sugar gives a beautiful finish, and of course, a generous drizzle of real maple syrup ties it all together with pure sweetness.

Side Dishes

Since this Brioche French Toast Casserole Recipe is already loaded with flavor, I like to pair it with something light and fresh, like a side of mixed greens with a lemon vinaigrette. Crispy bacon or a savory breakfast sausage also work great if you want some savory balance on the plate.

Creative Ways to Present

For special occasions, I’ve served this casserole in individual ramekins for a personal touch—each guest gets their own perfectly portioned “French toast cake.” Another fun idea is layering the casserole with thin slices of fresh peaches or apples tucked in between the bread triangles before baking, adding both flavor and a stunning layered look.

Make Ahead and Storage

Storing Leftovers

Leftover casserole keeps surprisingly well. I usually cover the dish tightly with plastic wrap and store it in the fridge for up to 5 days. This makes for a quick and hearty breakfast during a busy workweek. Just remember to reheat gently to avoid drying it out.

Freezing

I’ve frozen this casserole a couple of times with great success. After assembling but before baking, I wrap the dish tightly in plastic wrap and then aluminum foil, and freeze for up to 3 months. When you’re ready, thaw it overnight in the fridge, then bake as usual. It’s perfect for prepping meals ahead!

Reheating

To keep the texture just right when reheating, I prefer to pop leftover servings in a 160°C (320°F) oven for 10-15 minutes until warmed through and the top crisps back up. Microwaving is quicker but tends to make it chewy or soggy, so I save that for emergencies.
