Why You’ll Love This Recipe

  1. Convenient and Time-Saving: As the name suggests, you prepare this casserole the night before. This makes it perfect for busy mornings or when you’re hosting guests.
  2. Crowd-Pleaser: Whether you’re making it for your family, friends, or a brunch gathering, this dish is sure to be a hit. Its rich flavor and comforting texture will have everyone asking for seconds!
  3. Customizable: You can easily adapt this recipe by adding your favorite toppings, such as fresh berries, whipped cream, or a drizzle of syrup. You can also swap out the bread or add cinnamon, vanilla, or even chocolate chips to make it your own.

Ingredients You’ll Need:

  • Bread: Use sturdy bread like challah, brioche, or French bread. Day-old bread works best because it soaks up the custard without becoming too soggy.
  • Eggs: They create the rich, custardy texture.
  • Milk and Heavy Cream: These help make the casserole creamy and smooth.
  • Vanilla Extract: Adds a wonderful aroma and flavor.
  • Brown Sugar: Gives the casserole sweetness and a caramelized finish when baked.
  • Cinnamon: For a warm, comforting spice.
  • Salt: To balance the sweetness and enhance the flavors.
  • Butter: For greasing the pan and a buttery flavor.

How to Make Overnight French Toast Casserole:

  1. Prepare the Bread: Start by cutting your bread into cubes and arranging it in a greased 9×13-inch baking dish. You can let the bread sit out for a few hours or overnight to dry out slightly for the best results.
  2. Make the Custard: In a mixing bowl, whisk together eggs, milk, heavy cream, brown sugar, cinnamon, vanilla extract, and a pinch of salt. Pour this mixture over the bread cubes, ensuring that all pieces are evenly coated.
  3. Refrigerate Overnight: Cover the baking dish with plastic wrap and refrigerate overnight. This step allows the bread to soak up the custard, resulting in a soft and moist casserole.
  4. Bake: In the morning, preheat your oven to 350°F (175°C). Remove the casserole from the fridge and let it come to room temperature while the oven heats up. Bake for 45-55 minutes, or until the top is golden brown and the casserole is set.
  5. Serve: Once baked, let the casserole cool slightly before serving. Top with your favorite toppings like powdered sugar, fresh berries, or maple syrup.

Tips for the Perfect Overnight French Toast Casserole:

  • Use Stale Bread: Fresh bread can become too soggy when soaked in custard. For best results, use slightly stale bread, or dry it out by leaving it out for a few hours before using.
  • Add Toppings: You can add extra flavor and texture by sprinkling chopped nuts (like pecans or walnuts) or chocolate chips on top before baking.
  • Make It Ahead for Holidays: This casserole is perfect for holidays like Christmas or Easter when you want to impress your guests without spending hours in the kitchen.
  • Add Fruit: For a fresh and vibrant touch, add sliced bananas, berries, or apples to the casserole before baking.

Storage Tips:

  1. Refrigerating Leftovers: Store any leftover casserole in an airtight container in the fridge. It should keep well for up to 3 days. Reheat individual portions in the microwave or place the casserole in the oven at 350°F (175°C) for about 15 minutes, until heated through.
  2. Freezing for Later: If you want to make the casserole ahead of time and store it for a later date, you can freeze it before baking. Cover the unbaked casserole tightly with plastic wrap and aluminum foil, then freeze for up to 3 months. When you’re ready to bake, allow it to thaw in the fridge overnight and bake as directed the next morning.
  3. Reheating from Frozen: To reheat a frozen casserole, bake it directly from the freezer at 350°F (175°C) for 1 hour or until it’s completely heated through. If it was thawed overnight, follow the regular baking instructions.

By following these serving and storage tips, you can ensure that your Overnight French Toast Casserole stays fresh and delicious, whether you’re serving it immediately or enjoying it as leftovers!

1. Can I use any type of bread for this casserole?

Yes, you can use a variety of bread for Overnight French Toast Casserole, but sturdy, slightly stale bread works best. Popular choices include challah, brioche, or French bread. These types absorb the custard mixture without getting too soggy, ensuring a soft interior and a slightly crispy top.

Absolutely! You can make a dairy-free and egg-free version of this casserole. Substitute the eggs with a flax egg or a chia egg (1 tablespoon of ground flaxseed or chia seeds mixed with 3 tablespoons of water). For the dairy, you can use almond milk, soy milk, or oat milk, and replace the heavy cream with coconut cream or a plant-based cream alternative.


3. Can I prepare the casserole in advance and freeze it?

Yes, you can freeze the casserole before baking. To do so, assemble the casserole as instructed, cover it tightly with plastic wrap and aluminum foil, and freeze for up to 3 months. When you’re ready to bake it, allow it to thaw in the fridge overnight, and then bake it as usual the next morning.


4. Can I add toppings like chocolate chips, nuts, or fruit to the casserole?

Absolutely! You can customize your casserole by adding toppings like chocolate chips, nuts (such as walnuts or pecans), or fresh fruit (like sliced bananas or berries).

  • 1/2 cup (120 ml) heavy cream

Instructions

  1. Prepare the casserole base:
    • Grease a 9×13-inch (23×33 cm) baking dish. Arrange the cubed bread evenly in the dish.
    • In a large mixing bowl, whisk together the eggs, milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt until smooth.
  2. Soak the bread:
    • Pour the custard mixture evenly over the bread cubes, pressing down gently to ensure all the bread is soaked. Cover with plastic wrap and refrigerate overnight (or at least 4 hours).
  3. Make the crumble topping:
    • In a medium bowl, mix the brown sugar, granulated sugar, flour, cinnamon, and nutmeg. Add the cold, cubed butter and use a pastry cutter or your fingers to combine until the mixture resembles coarse crumbs. Cover and refrigerate until ready to use.

  5. Serve:
    • Let the casserole cool for 5–10 minutes before serving. Drizzle with maple syrup, dust with powdered sugar, or top with fresh berries, if desired.

Notes

  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
