Step-by-Step Instructions
Prep your Dish: Spray a 9×13-inch baking dish with nonstick cooking spray. Add the cubed brioche in an even layer, setting it aside while you prepare the custard.
Make the Custard: In a large bowl, whisk together the eggs, milk, heavy cream, brown sugar, vanilla, cinnamon, and salt until smooth. Pour the mixture evenly over the bread cubes, pressing gently to ensure all pieces are soaked. Cover tightly with plastic wrap and refrigerate for at least 4 hours, or prefer to let it sit overnight.
Create the Topping: In a medium bowl, whisk together the flour, brown sugar, cinnamon, and kosher salt. Pour in the melted butter and mix until the mixture resembles large crumbs. Chill in the fridge until you’re ready to bake.
Bake It: Preheat your oven to 350F (175C). Remove the casserole from the fridge and sprinkle the topping evenly over the soaked bread.
The Baking Process: Bake uncovered for 45-55 minutes. Look for a golden brown top and set center. Let the casserole rest for about 10 minutes before serving. Dust with confectioners’ sugar and drizzle with pure maple syrup for that perfect finishing touch.
Chef’s Tips:
- Timing is Key: The longer you let the bread soak, the better the custard flavor will develop.
- Visual Cues: The casserole should be poofy and golden; if the center quivers, give it a few extra minutes in the oven.
- Avoid Overbaking: Keep an eye on it; burnt edges aren’t the flavor you want!
Expert Tips & Tricks
Storage: If you have leftovers (rare but possible!), tightly wrap and refrigerate for up to 3 days. Reheat in the oven to keep that wonderful texture.
Make-Ahead Instructions: You can assemble this casserole the night before and bake it in the morning, making it a perfect make-ahead dish.
Avoid Soggy Bread: Ensure your bread cubes are day-old or lightly toasted before soaking; this will help in absorbing the custard without being mushy.
Troubleshooting: If the casserole browns too quickly but the center isn’t set, cover it with aluminum foil until baking is complete.
Serving Suggestions
This Overnight French Toast Casserole is truly a showstopper on its own, but if you’re looking to elevate your brunch experience further, consider serving it alongside:
Bacon or Sausage: The savory flavors contrast beautifully with the sweetness of the casserole.
Fresh Fruit: A colorful fruit salad or fresh berries add a refreshing complementary note.
Yogurt: Consider a dollop of Greek yogurt for a creamy tang that cuts through sweetness.
Presentation is key! Dust the casserole with confectioners’ sugar just before serving for that Instagram-worthy look!
