What Is Overnight French Toast Casserole?

Overnight French Toast Casserole is a baked breakfast dish that transforms the classic French toast into an easy-to-make casserole. Instead of standing over the stove flipping slices of bread, you assemble everything in a baking dish, let the bread soak in a rich custard overnight, and bake it to golden perfection the next morning.

This approach not only saves time but also enhances the flavors, as the custard mixture deeply penetrates the bread, creating a creamy.

Why You’ll Love This Dish

Overnight French Toast Casserole offers several advantages that make it a standout recipe:

• Time-Saving: All the prep work is done the night before, so all you have to do in the morning is bake and serve.
• Flavorful and Rich: The overnight soak ensures every bite is infused with the flavors of vanilla, cinnamon, and nutmeg.
• Versatile: Customize the recipe with your favorite bread, toppings, or mix-ins to suit your taste.
• Perfect for Gatherings: It’s a crowd-pleaser that can easily be scaled up for larger groups.

Ingredients

To create the perfect Overnight French Toast Casserole, you’ll need the following ingredients:

• 1 loaf of brioche or challah bread, cubed
• 6 large eggs
• 2 cups whole milk
• 1 cup heavy cream
• 1/2 cup granulated sugar
• 1/2 cup brown sugar
• 1 tablespoon vanilla extract
• 1 teaspoon ground cinnamon
• 1/2 teaspoon ground nutmeg
• 1/4 teaspoon salt
• 1/2 cup unsalted butter, melted
• Optional toppings: powdered sugar, maple syrup, fresh fruit

Step-by-Step Instructions

Step 1: Prepare the Casserole

1. Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
2. Arrange the cubed bread evenly in the dish. Using day-old bread is recommended for optimal texture, as it absorbs the custard mixture without becoming too soggy.
3. In a large mixing bowl, whisk together eggs, milk, heavy cream, granulated sugar, brown sugar, vanilla, cinnamon, nutmeg, and salt until smooth. This custard mixture is the key to the casserole’s creamy texture and rich flavor.
4. Pour the custard mixture evenly over the bread cubes, ensuring all pieces are soaked. Use the back of a spoon to press the bread down gently.
5. Cover the dish with plastic wrap and refrigerate overnight (or at least 6 hours). The extended soak allows the flavors to meld and ensures a soft, custard-like interior.

Step 2: Bake the Casserole

1. Remove the casserole from the refrigerator 30 minutes before baking. This step helps it bake evenly by bringing it closer to room temperature.
2. Preheat the oven to 350°F (175°C).
3. Drizzle melted butter over the top of the casserole for a golden, crispy crust.
4. Bake uncovered for 45-55 minutes, or until the top is golden brown and the center is set. To test for doneness, insert a knife or toothpick into the center; it should come out clean.
5. Let the casserole cool for 5-10 minutes before serving. This allows the custard to set further, making it easier to slice and serve.

Tips for Success

• Choose the Right Bread: Brioche and challah are ideal for their soft, rich texture and ability to absorb the custard. French bread or sourdough can also work, but avoid overly soft sandwich bread.
• Adjust the Sweetness: Reduce the sugar if you prefer a less sweet dish, or add a drizzle of honey for a natural touch of sweetness.
• Experiment with Flavors: Enhance the custard with orange zest, almond extract, or even a splash of bourbon for a sophisticated twist.
• Use Toppings Wisely: Fresh fruit, whipped cream, or a sprinkle of powdered sugar add visual appeal and additional flavor.

Variations to Try

Nutty Delight

Add chopped pecans or walnuts to the casserole before baking for a crunchy texture.

Fruity Twist

Incorporate fresh or dried fruits like blueberries, strawberries, or raisins into the custard mixture.

Chocolate Lovers

Sprinkle chocolate chips over the bread cubes for a decadent treat.

Savory Version

Skip the sugar and cinnamon, and instead, use shredded cheese, cooked bacon, or sautéed vegetables for a savory breakfast casserole.

Frequently Asked Questions

1. What’s the best type of bread to use?

Brioche and challah are preferred for their rich, buttery flavor and ability to hold up to the custard. However, French bread, sourdough, or croissants are excellent alternatives.

2. Can I make this recipe dairy-free?

Yes! Substitute almond milk or oat milk for the whole milk and heavy cream. Use vegan butter for the topping to keep it dairy-free.

3. Can I freeze the casserole?

Absolutely. Assemble the casserole, cover it tightly, and freeze before baking. When ready to serve, thaw it in the refrigerator overnight and bake as directed.

4. How do I store leftovers?

Refrigerate leftovers in an airtight container for up to three days. Reheat individual portions in the microwave or oven for the best texture.

5. Can I prepare it on the same day?

While overnight soaking yields the best results, you can let the casserole soak for a minimum of two hours if you’re short on time.

Ingredients

1 loaf french bread or thick texas toast

8 eggs

2 cups half and half

1/2 cup milk

3 Tbsp granulated sugar

1 1/2 teaspoons pure vanilla extract

1/2 teaspoon ground cinnamon

1/2 teaspoon ground nutmeg

1/2 teaspoon salt

Cinnamon Crunch Topping:

1 1/2 sticks butter softened

1 cup light brown sugar packed

1 Tbsp light corn syrup optional

1 teaspoon ground cinnamon

1/2 teaspoon ground nutmeg

---

Instructions

Prepare a 9″x13″ baking dish by coating the entire inside of the dish with butter or cooking spray. Set aside.

Slice the French bread, about 1-inch thick. Arrange slices in your prepared baking dish in rows, overlapping the slices. Set aside.

In a large bowl, whisk eggs. Add half-and-half, milk, sugar, vanilla, cinnamon, nutmeg, and salt. Whisk until well combined.

Pour the egg mixture over the bread slices, making sure they are covered evenly. Spoon some of the mixture in between the slices making sure all the slices are completely covered. Cover with foil and refrigerate overnight.

The next day, preheat oven to 350°F. Meanwhile, carefully flip each piece of bread over to make sure everything is nice and coated with the mixture.

Make the Topping:

Combine all ingredients in a medium bowl and mix to combine. Spoon the topping on top of the prepared bread slices. Then spread evenly over the bread (like you are icing a cake). You can also spread some of the mixture in between the slices to make sure the entire slice is covered (if you prefer).

Bake for 35-40 minutes (no need to cover with foil), until puffed and lightly golden.
