Why You Will Love This Recipe

This Baked French Toast Casserole is a favorite for many reasons. First, it is incredibly convenient because you can prepare it the night before, meaning you only have to pop it in the oven when you wake up. It is also highly customizable, allowing you to use different types of bread like sourdough or French baguette. Whether you are hosting a Mother’s Day brunch, a Christmas morning breakfast, or a birthday celebration, this dish serves a crowd with minimal effort. The combination of warm cinnamon, fresh berries, and a crunchy sugar crust makes it an irresistible treat.

Ingredients

• 1 loaf of sliced bread (Brioche, Challah, or French bread; approximately 18oz)
• 6 large eggs
• 2 cups of milk (any variety, including plant-based)
• 1/3 cup of half and half
• 1/3 cup of granulated sugar (plus 2 extra tablespoons for the topping)
• 1 teaspoon of vanilla extract
• 1 teaspoon of ground cinnamon
• 1 pinch of salt
• 1 cup of nuts (walnuts, pecans, hazelnuts, or sliced almonds)
• 3 cups of fresh berries (blueberries, raspberries, or strawberries)
• Maple syrup for serving
• Powdered sugar for dusting

Step-by-Step Instructions

1. Prepare the Custard: In a large mixing bowl, whisk together the eggs, milk, half and half, 1/3 cup of sugar, vanilla extract, cinnamon, and a pinch of salt until the mixture is well combined.
2. Dip the Bread: Take each slice of bread and dip it into the custard base, ensuring it is thoroughly submerged. Arrange the soaked slices in a 9×13 inch casserole dish so that they overlap slightly.
3. Soak the Casserole: Pour any remaining custard mixture over the bread in the pan. Cover the dish tightly with foil and refrigerate for at least 15 minutes, though soaking overnight is highly recommended for the best texture.
4. Add the Sugar Topping: When you are ready to bake, preheat your oven to 375°F. Remove the dish from the fridge and sprinkle the remaining 2 tablespoons of sugar evenly over the top of the bread to create a caramelized crust.
5. Initial Bake: Keep the dish covered with foil and bake on the middle rack for 25 minutes.
6. Crisp the Top: Remove the foil and continue baking for another 20 to 25 minutes. The sugar should bubble and turn into a golden-brown, crispy crust. If you have a convection fan, turn it on for the last 10 minutes to enhance the crunch.
7. Serve: Remove from the oven and top with fresh berries, nuts, and a dusting of powdered sugar. Serve immediately with plenty of maple syrup.

Expert Tips / Pro Tips

To get the best results with your Baked French Toast Casserole, use day-old bread. Slightly stale bread is drier and more porous, which allows it to absorb the custard without becoming overly soggy. Additionally, aim for thick slices between 3/4 and 1 inch thick to maintain the structure of the dish. If you notice certain spots on the bread are browning too quickly during the final stages of baking, loosely tent those specific areas with foil to prevent burning while the rest of the casserole finishes.

While brioche and challah are the gold standards for this recipe, you can experiment with different breads. Sourdough adds a lovely tang that balances the sweetness, while a French baguette provides a sturdier chew. For the spices, feel free to swap or add nutmeg, cloves, or even pumpkin spice for a seasonal twist. If you need a dairy-free option, you can easily substitute the milk and half and half with oat milk or coconut milk.

Serving Suggestions

This casserole is a showstopper on its own, but you can elevate it with various toppings. Fresh fruit like sliced peaches or apples works beautifully alongside the berries. For extra indulgence, try a dollop of whipped cream, a drizzle of chocolate syrup, or even a bit of caramel sauce. Pair it with savory sides like crispy bacon or breakfast sausage to balance the sweetness of the maple syrup.

If you have leftovers, store them in an airtight container in the refrigerator for up to 4 days. To maintain the crispy texture, it is best to reheat slices in a toaster oven at 350°F until warmed through. You can also use a microwave for a quicker option, though the crust will be softer. This casserole can also be frozen after baking; wrap individual slices tightly and freeze for up to 2 months, thawing in the fridge before reheating.
