Ingredients
- 1 loaf (16 ounces) Brioche bread, cubed (the richer, the better!)
- 8 large eggs, room temperature, beaten (fresh farm eggs are ideal)
- 2 cups (490 g) whole milk, room temperature (substitute with almond milk for a dairy-free version)
- 1/2 cup (119 g) heavy whipping cream, room temperature (for a lighter option, use half-and-half)
- 3/4 cup (150 g) light brown sugar, packed (helps create that caramelized flavor)
- 2 teaspoons vanilla extract (pure vanilla adds the best flavor, but imitation works in a pinch!)
- 1 teaspoon cinnamon (for that warm, comforting touch)
- 1/2 teaspoon kosher salt (balances the sweetness)
Topping:
- 1/2 cup (62.5 g) all-purpose flour (make sure to scoop it correctly to avoid a dense topping)
- 1/2 cup (100 g) light brown sugar, packed
- 1 teaspoon ground cinnamon
- 1/4 teaspoon kosher salt
- 1/2 cup (1 stick / 113 g) unsalted butter, melted (room temperature for blending)
- Confectioners’ sugar, for garnish (optional but so pretty!)
- Pure maple syrup, for serving (because life’s too short for anything less!)
Notes:
- Use high-quality brioche or challah bread for the best texture.
- Make sure to allow your eggs, cream, and milk to come to room temperature as described; it helps create a well-mixed custard.
Step-by-Step Instructions
Prepare the Dish: Start by spraying a 9×13-inch baking dish with nonstick cooking spray. Add the cubed brioche in an even layer, making a beautiful base for your casserole.
Make the Custard: In a large mixing bowl, whisk together the beaten eggs, whole milk, heavy cream, brown sugar, vanilla extract, cinnamon, and kosher salt. Make sure it’s smooth and mixed well—this is where all the flavor comes from! Once ready, pour this custard mixture evenly over the bread cubes. Gently press down to ensure every piece of bread gets soaked. Cover with plastic wrap and refrigerate for at least 4 hours, or let it sit overnight for the best results.
Prepare the Topping: In a medium bowl, whisk together the flour, brown sugar, ground cinnamon, and kosher salt for the topping. Now, add the melted butter and mix until crumbly and everything is well combined. Cover this topping mixture and refrigerate until you’re ready to bake!
Bake: Preheat your oven to 350F (175C). Remove the casserole from the fridge and sprinkle the prepared topping evenly over the soaked bread. Bake uncovered for 45-55 minutes, or until the top is golden brown and the center is set. You’ll know it’s ready when the top is slightly crispy and the edges look deliciously chewy!
Rest & Serve: Let the casserole rest for 10 minutes before serving. Dust generously with confectioners’ sugar, and don’t forget to offer a drizzle of pure maple syrup on the side—it’s the perfect finishing touch!
Chef’s Tips:
- Don’t rush! Allow the bread to soak fully for the best texture.
- Keep an eye on it towards the end of the baking time to prevent over-browning. If it browns too quickly, loosely cover with aluminum foil.
Expert Tips & Tricks
Store Leftovers: If you have leftovers (which is rare!), store them in an airtight container in the fridge for up to 3 days. Reheat in the oven or the microwave, adding a few drops of milk if needed.
Make Ahead: This casserole is perfect for prepping ahead of time. Assemble everything the night before, and just pop it in the oven the next day.
Troubleshooting: If your casserole isn’t setting in the middle, try lowering the oven temperature and baking a bit longer. It’s okay to leave the casserole to cool for some time—it’ll firm up as it rests!
Experiment with Variations: Don’t hesitate to mix in your favorites! Blueberries, pears, or even chocolate chips can be added to the base for a fun twist.
Freezer Friendly: You can freeze the casserole before baking. Just cover it tightly in foil and freeze. When you’re ready to enjoy it, thaw in the refrigerator overnight, then bake as directed.
Serving Suggestions
Pair your Overnight French Toast Casserole with crispy bacon or savory sausage links! Fresh fruit, like strawberries and blueberries, adds a lightness that complements the richness of the casserole, while a side of whipped cream won’t hurt either. For special occasions, serve with mimosas or coffee to elevate your brunch experience. Presentation matters, so feel free to layer your serving platters with fresh mint or edible flowers for an elegant touch.
Variations & Substitutions
Flavors: Consider adding a swirl of Nutella or chunks of chocolate for a decadent treat. Seasonal fruits like apples or peaches make delightful additions!
