How this recipe comes together

Making this Overnight French Toast Casserole is surprisingly straightforward, and most of the work happens while you’re sleeping! You’ll start by preparing your bread, cutting it into cubes, and arranging it in a baking dish. Next, you whisk together a rich, custardy mixture of eggs, milk, sugar, and spices. This liquid gold gets poured over the bread, ensuring every piece is thoroughly saturated. Then, into the fridge it goes for an overnight slumber, allowing the bread to soak up all that flavor. The next morning, you can whip up an optional streusel topping, sprinkle it over the casserole, and bake it until golden brown and bubbly. The real fun begins when it’s time to choose from the six fantastic topping ideas to customize each serving!

Essential ingredients

To create this delightful Overnight French Toast Casserole, you’ll need a handful of pantry staples and a good loaf of bread.

• 1 loaf (1 pound) French bread, challah, or brioche, cut into 1-inch cubes
• 8 large eggs
• 2 cups whole milk (or half-and-half for extra richness)
• ½ cup granulated sugar
• 2 teaspoons vanilla extract
• 1 teaspoon ground cinnamon
• ½ teaspoon ground nutmeg
• ¼ teaspoon salt

For the Streusel Topping (Optional, but highly recommended!):

• ½ cup all-purpose flour
• ¼ cup packed light brown sugar
• ¼ cup cold unsalted butter, cut into small pieces
• ½ teaspoon ground cinnamon

A note on bread: Using a slightly stale loaf works wonders here, as it absorbs the custard even better without becoming soggy. If your bread is fresh, you can cut it and let it sit out for a few hours to dry slightly.

Directions to follow

Get ready to make your breakfast dreams a reality with these clear steps.

1. Prepare the Bread: Grease a 9×13-inch baking dish. Arrange the bread cubes evenly in the prepared dish.
2. Make the Custard: In a large bowl, whisk together the eggs, milk, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined and smooth.
3. Soak Overnight: Pour the egg mixture evenly over the bread cubes, making sure all pieces are coated. Gently press down on the bread to help it absorb the liquid. Cover the dish tightly with plastic wrap and refrigerate for at least 8 hours, or preferably overnight.
4. Prepare Streusel (if using): About 30 minutes before baking, remove the casserole from the refrigerator. While the oven preheats, make the streusel. In a small bowl, combine the flour, brown sugar, and cinnamon. Cut in the cold butter with your fingers or a pastry blender until the mixture resembles coarse crumbs.
5. Bake: Preheat your oven to 375°F (190°C). If using, sprinkle the streusel topping evenly over the casserole. Bake for 45-55 minutes, or until the casserole is golden brown, puffed up, and a knife inserted into the center comes out clean.
6. Serve: Let the casserole rest for 5-10 minutes before serving. This allows it to set slightly.

How to plate and pair

This Overnight French Toast Casserole is a star on its own, but the right accompaniments truly make it shine. Once baked, let it cool for a few minutes and then cut it into generous squares. For a beautiful presentation, dust with a sprinkle of powdered sugar just before serving.

Here are six amazing topping ideas to take your casserole from great to unforgettable:

1. Classic Maple Pecan: Warm maple syrup and toasted pecans. Simple, elegant, and always a crowd-pleaser.
2. Berry Bliss: A medley of fresh berries (strawberries, blueberries, raspberries) and a dollop of whipped cream. Bright, fresh, and colorful.
3. Caramelized Apple & Cinnamon: Sautéed apple slices cooked down with butter, brown sugar, and extra cinnamon until tender and slightly caramelized.
4. Chocolate Hazelnut Drizzle: A generous drizzle of warm Nutella or another chocolate-hazelnut spread, perhaps with some chopped toasted hazelnuts.
5. Citrus Zest & Yogurt: A dollop of Greek yogurt for tang, brightened with fresh orange or lemon zest and a light honey drizzle.
6. Tropical Coconut & Mango: Diced fresh mango chunks, toasted coconut flakes, and a hint of lime zest. A sunshine-filled topping!

Serve alongside some crispy bacon or savory breakfast sausage, and a refreshing fruit salad to complete your brunch spread.

Keeping leftovers fresh

One of the great things about this casserole is how well it holds up, making it perfect for meal prepping if you manage to have any leftovers!

• Storage: Allow the casserole to cool completely. Store individual portions or the entire remaining casserole in an airtight container in the refrigerator for up to 3-4 days.
• Reheating: To reheat individual slices, you can warm them in the microwave for 1-2 minutes until heated through. For a crispier exterior, reheat in a toaster oven or conventional oven at 350°F (175°C) for about 10-15 minutes, or until warmed through.
• Freezing: This casserole freezes beautifully! Once completely cooled, cut it into individual portions. Wrap each portion tightly in plastic wrap, then an additional layer of aluminum foil, or place in a freezer-safe bag or container. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating as directed above.

Helpful cooking tips

Achieving that perfect, custardy French toast casserole is easier than you think with a few insider tricks:

• The Right Bread: Don’t skimp on the bread! Challah or brioche make for an incredibly rich and tender casserole. French bread is also a fantastic, slightly firmer option. A slightly stale loaf (a day or two old) is actually ideal as it will absorb more of the custard without turning mushy.
• Don’t Rush the Soak: The “overnight” in Overnight French Toast Casserole isn’t just a suggestion! That long soak is crucial for the bread to fully absorb the egg mixture, ensuring a uniformly moist and flavorful result. A minimum of 8 hours is good, but 12-18 hours is even better.
• Evenly Distributed Custard: Make sure you press the bread down gently into the custard after pouring. This helps all the pieces get saturated, preventing dry spots later.
• Rest Before Serving: After baking, let the casserole rest for 5-10 minutes. This allows the custard to set a bit more, making for cleaner cuts and a more stable slice.

There are many variations you can perform to the recipe.

Creative twists

This Overnight French Toast Casserole is a fantastic canvas for your culinary creativity. Here are some ideas to mix things up:

• Pumpkin Spice Delight: Add 1 tablespoon of pumpkin pie spice to the custard mixture and replace some of the milk with a touch of pumpkin puree (about ¼ cup). Top with candied pecans.
• Banana Bread Casserole: Mash 1-2 ripe bananas and whisk them into the custard for a banana bread-like flavor. Add a streusel topping with walnuts.
• Savory Twist: Omit the sugar and cinnamon, and instead whisk in a pinch of black pepper, some grated Gruyere or cheddar cheese, and cooked crumbled sausage or bacon into the custard. Serve with a fried egg on top.
• Gluten-Free Option: Simply swap out the standard bread for your favorite robust gluten-free bread. Ensure it’s a type that holds up well for soaking.
• Dairy-Free Version: Use a plant-based milk (like almond or oat milk) and coconut oil or a vegan butter substitute for the streusel (if using).

Your questions answered

Can I prepare this casserole without an overnight soak?

While the overnight soak is highly recommended for the best texture and flavor, you can technically prepare it with a shorter soak. If you’re really short on time, let it soak at room temperature for at least 30 minutes to an hour, pressing the bread down occasionally to ensure absorption. However, for that truly custardy, melt-in-your-mouth result, an overnight rest in the fridge is ideal.

My casserole turned out soggy in the middle. What went wrong?

Sogginess usually indicates the bread didn’t quite absorb enough liquid, or it wasn’t baked long enough. Ensure your bread cubes are not too tightly packed in the dish, allowing the custard to get in between them. Also, always make sure the bake time is sufficient – a knife inserted into the center should come out clean, and the casserole should be puffed and golden. Using a slightly stale bread helps prevent this too.

Can I add fruit directly into the casserole before baking?

You can! However, be mindful of watery fruits like fresh berries, as they can release a lot of moisture during baking and potentially make the casserole a bit soggy. If adding fresh fruit like berries or sliced peaches, it’s often best to reserve them for topping after baking. If you want to bake fruit in, opt for something like diced apples or pears, which hold up better, or consider lightly cooking berries with a bit of sugar beforehand to reduce their water content.
