Why This French Toast Casserole Works Perfectly for Holidays


Holiday mornings often come with a mix of excitement and chaos. Preparing breakfast ahead of time helps reduce stress and allows you to enjoy the festivities. This casserole combines the familiar flavors of French toast with the ease of a one-dish meal. The night-before preparation means the bread soaks up the custard overnight, resulting in a tender, flavorful bake that tastes like it took hours to make.


The recipe uses brioche bread, which adds a buttery richness and soft texture. The combination of milk and heavy cream creates a creamy custard that keeps the casserole moist. Cinnamon and vanilla add warmth and aroma, making it a comforting dish that fills your home with inviting scents.


Because it can be refrigerated overnight, this casserole is perfect for holiday guests or family gatherings. You can customize toppings like powdered sugar, fresh fruit, or even a drizzle of maple syrup to suit your taste.


Ingredients


  • 1 loaf of sliced brioche bread

  • 5 large eggs

  • 1 ½ cups milk

  • ½ cup heavy cream

  • 1 tablespoon vanilla extract

  • 1 teaspoon ground cinnamon

  • ½ cup granulated sugar

  • ½ cup melted unsalted butter

  • ½ cup brown sugar

  • Optional: powdered sugar and fresh fruit for topping


Step-by-Step Directions



  1. Prepare the bread by arranging the sliced brioche in a baking dish. You can leave the slices whole for a classic look or cut them into cubes for a more textured casserole.

  2. Mix the custard by beating the eggs in a large bowl. Add milk, heavy cream, vanilla extract, cinnamon, granulated sugar, and melted butter. Whisk until the mixture is smooth and well combined.

  3. Pour the custard evenly over the bread in the baking dish. Press the bread gently to ensure it soaks up the custard.

  4. Sprinkle brown sugar evenly over the top of the casserole. This will caramelize during baking and add a sweet, crunchy topping.

  5. Cover and refrigerate if making ahead. Let the casserole sit overnight or for at least 4 hours to allow the bread to absorb the custard fully.

  6. Preheat the oven to 375°F (190°C).

  7. Bake uncovered in the preheated oven for 35 to 40 minutes. The casserole is done when it is set in the middle and the top is golden brown.

  8. Cool slightly after baking. Optionally, dust with powdered sugar and add fresh fruit before serving.


Tips for Serving and Variations


  • Serve the casserole warm with maple syrup or a dollop of whipped cream for extra indulgence.

  • Add chopped nuts like pecans or walnuts to the brown sugar topping for a crunchy texture.

  • For a fruity twist, layer sliced strawberries or blueberries between the bread slices before pouring the custard.

  • Use challah bread or a sturdy white bread if brioche is unavailable, but brioche offers the best flavor and texture.


This French Toast Casserole is a crowd-pleaser that simplifies holiday mornings without sacrificing flavor or presentation. Preparing it ahead means you can enjoy a stress-free morning and focus on what matters most—spending time with loved ones.
