Diet-Friendly Options: Easily adaptable for gluten-free or dairy-free diets with simple substitutions.

Ingredients You’ll Need

1 pound day-old brioche or challah, cut into 1-1½ inch cubes: The key to a custardy texture! If you don’t have it on hand, you can use regular bread, but the rich flavor of brioche or challah is hard to beat.
7 large eggs: These provide the structure and richness to the casserole. Make sure they’re room temperature for better mixing.
¾ cup heavy cream: Adds a luxuriously creamy texture; can substitute with full-fat coconut milk for dairy-free options.
1¾ cups whole milk: You can replace it with almond or oat milk if you’re looking for a lighter or dairy-free version.
⅓ cup maple syrup (or honey): Sweetens the dish beautifully! Real maple syrup will give superior flavor compared to pancake syrup.
1 tablespoon vanilla bean paste (or vanilla extract): This brings out a delightful depth of flavor. If you don’t have vanilla bean paste, pure vanilla extract will work too.
1 teaspoon ground cinnamon: Adds warmth; don’t skimp on this!
¼ teaspoon ground cardamom (optional but recommended): This gives an exotic undertone that enhances the dish, though you can leave it out if you prefer.
¼ teaspoon salt: Balances the sweetness and enhances all the flavors.
¼ cup granulated sugar: Sweetens the custard; feel free to adjust to your taste.
2 tablespoons light brown sugar: Adds a subtle caramel note that complements the flavors perfectly.
1 teaspoon cinnamon: Use it with the sugar mixture for a crunchy topping!
Pinch of salt: Just a little extra for the topping.
3 tablespoons cold butter, grated or finely diced: Creates a tasty, crispy topping. You can omit if you’re looking for a lighter version.
Powdered sugar: Optional garnish for a pretty final touch.
Fresh berries: Perfect for serving on the side or adding on top for a fresh contrast.
Warm maple syrup or honey: A delightful drizzle over each serving makes it extra special.

How to Make Overnight Vanilla Bean French Toast Casserole

Prepare the Base: In a large bowl, whisk together 7 large eggs, ¾ cup heavy cream, 1¾ cups whole milk, ⅓ cup maple syrup (or honey), 1 tablespoon vanilla bean paste, 1 teaspoon ground cinnamon, ¼ teaspoon ground cardamom, ¼ teaspoon salt, ¼ cup granulated sugar, and 2 tablespoons light brown sugar.
Combine with Bread: Add the cubes of day-old brioche (or challah) into the egg mixture. Lightly toss to ensure all pieces are coated in the custard mixture.
Soak Overnight: Transfer the mixture to a 9×13-inch casserole dish. Cover with plastic wrap and let it sit in the refrigerator overnight. This will allow the bread to soak up all the wonderful flavors.
Prepare the Topping: The next morning, preheat your oven to 350°F (175°C). In a small bowl, mix 1 teaspoon cinnamon, pinch of salt, and 3 tablespoons of cold butter (grated or diced) until crumbly. Sprinkle over the top of the casserole.
Bake: Place the casserole in the preheated oven. Bake for 45 minutes or until the top is golden brown and the center is set (toothpick should come out clean).
Serve Warm: Let it cool slightly, then dust generously with powdered sugar, serve with fresh berries, and warm maple syrup or honey.

Storing & Reheating

To store, keep any leftovers in an airtight container in the refrigerator for up to 3 days. Alternatively, you can freeze individual portions for up to 3 months. To reheat, simply microwave for 1-2 minutes or warm in a 350°F oven for 10-15 minutes. Note that freezing may slightly alter the texture, but refreshing it with butter before reheating can help!

Chef’s Helpful Tips

Be sure to use day-old bread to avoid a soggy casserole—fresh bread won’t absorb the custard properly.
For an extra creamy result, use room temperature eggs and allow the milk to warm slightly before mixing.
To enhance flavor, experiment with additional spices like nutmeg or vanilla extract.
If you’re prepping for a holiday meal, assemble the casserole a day or two in advance, cover, and just pop in the oven when ready.
If you prefer a sweeter topping, consider adding a sprinkle of powdered sugar right before serving.

This Overnight Vanilla Bean French Toast Casserole isn’t just a breakfast; it’s a warm, flavorful embrace that brings everyone together. Enjoy the delight of this comforting dish, whether for special occasions or simply treating yourself on a lazy morning. Experiment with toppings and flavors to make it uniquely yours—there’s no limit to the deliciousness it can bring to your table!

Recipe FAQs

Can I use gluten-free bread for this recipe?

Absolutely! Gluten-free bread works well in this casserole; just ensure you choose a hearty loaf to withstand the soaking.

How long can I store the casserole before baking?

You can prepare the casserole and let it soak in the refrigerator for up to 24 hours before baking. Just make sure it is well covered to prevent drying out.

Can I make this casserole the same day?

While it’s best to allow it to soak overnight, you can still enjoy it the same day! Just let it sit for at least 30 minutes to an hour for the bread to absorb some of the custard.

How can I customize my French toast casserole?

Feel free to mix in your favorite fruits like bananas, apples, or nuts for added texture and flavor. You can also swap out the spices according to your taste preferences.

Instructions

Butter a 9×13 inch baking dish generously.
Add the bread cubes and spread them into an even layer without packing them down.
In a large bowl, whisk the eggs until smooth and then add heavy cream, milk, maple syrup, vanilla, cinnamon, cardamom (if using), and salt. Whisk until combined.
Pour the custard mixture evenly over the bread and gently press down to help it absorb the liquid. Cover and refrigerate overnight or for at least 8 hours.
In a small bowl, mix granulated sugar, brown sugar, cinnamon, and salt. Add the cold butter and rub it into the sugar until small clumps form. Cover and refrigerate.
The next morning, preheat your oven to 350°F. Remove the casserole from the fridge as the oven heats.
Sprinkle the sugar mixture evenly over the soaked bread and bake uncovered for 40-45 minutes until golden and set but still soft in the center.
Let the casserole rest for 10 minutes before serving.
Serve warm topped with powdered sugar, fresh berries, and a drizzle of warm maple syrup or honey if desired.

Notes

Using day-old bread helps achieve the perfect texture in the casserole.
Feel free to add your favorite fruits or nuts for extra flavor and texture.
For a richer custard, you can substitute part of the milk with more cream.
