Ingredients

Scale

Bread

  • 1 loaf brioche (or challah, or French bread), cut into 1-inch cubes

Custard Mixture

  • 6 large eggs
  • 2 cups whole milk
  • 1/2 cup granulated sugar
  • 1 tablespoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt

Topping

  • 1/2 cup unsalted butter, melted

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it reaches the right temperature for baking the casserole.
  2. Prepare Baking Dish: Grease a 9×13-inch baking dish with butter or nonstick spray to prevent sticking and make cleanup easier.
  3. Arrange Bread: Spread the cubed brioche evenly in the prepared baking dish, creating an even layer to absorb the custard thoroughly.
  4. Mix Custard: In a large mixing bowl, whisk together the eggs, whole milk, granulated sugar, vanilla extract, ground cinnamon, and salt until the mixture is smooth and well combined.
  5. Soak Bread: Pour the custard mixture evenly over the bread cubes, pressing down lightly to help the bread absorb the liquid for a rich flavor and custardy texture.
  6. Add Butter: Drizzle the melted unsalted butter over the top of the custard-soaked bread for added richness and a golden crust.
  7. Let Soak: Allow the casserole to sit for 10 minutes so the bread fully soaks up the custard mixture before baking.
  8. Bake: Bake the casserole uncovered in the preheated oven for 40 minutes, or until the top is golden brown and the center is fully set.
  9. Cool Slightly: Remove the baked casserole from the oven and let it cool for a few minutes to set further before serving.
  10. Serve: Serve warm, optionally topped with maple syrup, powdered sugar, or fresh berries to enhance flavor and presentation.

Notes

  • Use stale or day-old bread if possible; it soaks up the custard better and prevents a soggy casserole.
  • Feel free to substitute half-and-half or heavy cream for whole milk for a richer custard.
  • Adding nuts like pecans or walnuts on top before baking adds a delightful crunch.
  • Cover and refrigerate overnight after assembling for a make-ahead option; add extra baking time if baking cold.
  • Leftovers can be refrigerated and reheated in the oven or microwave for a quick breakfast.
