FAQs
Can I use a different type of bread?
Yes, brioche, challah, or French bread work best for their rich texture, but you can substitute with other sturdy breads like sourdough or Italian bread. Avoid very soft or pre-sliced sandwich bread as it might become too soggy.
Can I make this recipe dairy-free?
Yes, substitute the whole milk with a plant-based milk like almond or oat milk, and use dairy-free butter or oil for greasing and drizzling. The texture and flavor will be slightly different but still delicious.

Ingredients
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
- Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it reaches the right temperature for baking the casserole.
- Prepare Baking Dish: Grease a 9×13-inch baking dish with butter or nonstick spray to prevent sticking and make cleanup easier.
- Arrange Bread: Spread the cubed brioche evenly in the prepared baking dish, creating an even layer to absorb the custard thoroughly.
- 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.
- 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.
- Add Butter: Drizzle the melted unsalted butter over the top of the custard-soaked bread for added richness and a golden crust.
- Let Soak: Allow the casserole to sit for 10 minutes so the bread fully soaks up the custard mixture before baking.
- 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.
- Cool Slightly: Remove the baked casserole from the oven and let it cool for a few minutes to set further before serving.
- 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.
