Ingredients

Gather these simple ingredients to create your next favorite make-ahead breakfast. This french toast casserole overnight uses common pantry staples for maximum convenience.

For the French Toast Casserole:

• 1 pound loaf of brioche, challah, french bread, or white bread
• 8 large eggs
• 1 cup heavy cream
• 2 cups milk
• 1/4 cup light brown sugar
• 2 teaspoons ground cinnamon
• 1/2 teaspoon kosher salt
• 1 Tablespoon vanilla extract

For the Streusel Topping:

• 3 Tablespoons light brown sugar (packed)
• 3 Tablespoons granulated sugar
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg
• 2 Tablespoons cold butter (cut into pieces)

Notes & Substitutions

For the best results, choose slightly stale bread; it absorbs the custard better without becoming soggy. The use of slightly stale bread is a common culinary technique to understand the culinary reasons for using stale bread. Brioche or challah provide a richer flavor, but French bread or even sturdy white bread works beautifully. You can substitute half-and-half or whole milk for heavy cream, adjusting for a slightly less rich custard. Feel free to use maple syrup instead of brown sugar in the custard for a different sweetness. Experiment with other warm spices like cardamom or a pinch of ground ginger for unique flavor twists.

Equipment

You won’t need many special tools for this simple breakfast casserole.

• 9×13 inch baking dish
• Large mixing bowls (at least two)
• Whisk
• Pastry blender (optional, hands work too)
• Sharp knife for cutting bread

Instructions

Follow these clear steps to create a perfect french toast casserole overnight. Preparing this ahead of time makes for an incredibly easy morning!

1. Prepare Baking Dish: Lightly grease a 9×13 inch baking dish. This prevents sticking and makes cleanup a breeze.
2. Cut and Arrange Bread: Cut your chosen bread into 1-inch chunks. Distribute these pieces evenly across the bottom of the prepared baking dish.
3. Whisk Custard Mixture: In a large mixing bowl, whisk the 8 large eggs until they are well beaten. Add the heavy cream, milk, 1/4 cup light brown sugar, 2 teaspoons ground cinnamon, kosher salt, and vanilla extract. Whisk thoroughly until all ingredients are fully combined and smooth.
4. Soak Bread: Pour the prepared custard mixture evenly over the bread cubes in the baking dish. Gently toss the bread to ensure every piece is thoroughly coated with the liquid. Spread the bread back into an even layer.
5. Refrigerate Overnight: Cover the baking dish tightly with plastic wrap or foil. Place it in the refrigerator and allow it to chill for a minimum of 8 hours, or ideally overnight. Proper refrigeration is crucial for food safety, especially when preparing dishes with raw eggs and dairy, as highlighted in these safe handling guidelines for dairy and eggs. This extended soak time is key for a tender, flavorful casserole.
6. Prepare Streusel Topping: In a separate medium bowl, combine 3 tablespoons light brown sugar, 3 tablespoons granulated sugar, 1 teaspoon ground cinnamon, and 1/4 teaspoon ground nutmeg. Stir these dry ingredients together. Add the cold, cubed butter and use a pastry blender or your fingertips to cut the butter into the sugar mixture until it forms a coarse, crumbly topping.
7. Refrigerate Topping: Cover the bowl of streusel topping and refrigerate it alongside the casserole. Keeping it cold ensures the best texture when baked.
8. Preheat Oven: The next morning, remove the casserole and streusel from the fridge. Preheat your oven to 350°F (175°C).
9. Add Topping: Uncover the french toast casserole. Evenly sprinkle the cold streusel topping over the soaked bread mixture in the baking dish.
10. Bake Casserole: Place the casserole in the preheated oven. Bake for approximately 45-50 minutes, or until the top is golden brown, the streusel is crisp, and the casserole is set in the center. A knife inserted near the center should come out clean.
11. Rest and Serve: Once baked, remove the casserole from the oven. Let it cool for at least 10 minutes before slicing and serving. This resting time helps the casserole set properly.

Pro Tips for Success

Achieve the best make-ahead French toast casserole by following these expert tips. They ensure a perfect texture and flavor every time.

• Use Slightly Stale Bread: This prevents your bread from becoming soggy by allowing it to absorb the custard more efficiently.
• Don’t Overmix Streusel: Mix just until crumbly; overmixing can create a dense, dough-like topping instead of a light, crisp one.
• Ensure Even Soaking: Gently toss the bread cubes after pouring the custard to make sure every piece is fully saturated.
• Avoid Overbaking: Bake until just set and golden. Overbaking can lead to a dry casserole.
• Tent with Foil: If your streusel topping starts browning too quickly, loosely tent the casserole with aluminum foil for the last 10-15 minutes of baking.

Serving, Storage & Variations

This versatile french toast casserole overnight is fantastic on its own, but these suggestions will elevate your breakfast experience.

Serving Suggestions

• Drizzle with maple syrup or your favorite homemade pancake syrup.
• Top with fresh berries like strawberries, blueberries, or sliced bananas.
• Add a dollop of whipped cream or a scoop of vanilla ice cream for dessert.
• A light dusting of powdered sugar makes for an elegant presentation.

Storage

• Store any leftover baked casserole in an airtight container in the refrigerator for up to 3-4 days.
• For longer storage, freeze individual portions or the entire unbaked/baked casserole tightly wrapped in plastic wrap and then foil for up to 2-3 months.

Reheating

• Warm individual portions in the microwave for 1-2 minutes until heated through.
• Reheat larger portions in an oven preheated to 300°F (150°C) for 15-20 minutes, or until warm.

Variations

• Fruity Twist: Fold in a cup of fresh or frozen berries, sliced apples, or peaches with the bread.
• Chocolate Lover: Mix in 1/2 cup of chocolate chips (milk, dark, or white) with the bread cubes.
• Nutty Crunch: Add 1/2 cup of chopped pecans or walnuts to the streusel topping for extra texture.
• Savory Touch: Omit the streusel. Add cooked bacon bits, shredded cheddar cheese, and a pinch of black pepper to the custard for a savory breakfast bake.
