Ingredients
-
1 loaf brioche, challah, or French bread, cut into 1-inch cubes
-
6 large eggs
-
2 cups whole milk
-
½ cup granulated sugar
-
1 tablespoon vanilla extract
-
1 teaspoon ground cinnamon
-
¼ teaspoon salt
-
½ cup unsalted butter, melted
Instructions
-
Preheat the Oven
Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray. -
Add the Bread
Spread the bread cubes evenly in the prepared baking dish. -
Make the Custard
In a large bowl, whisk together the eggs, milk, sugar, vanilla, cinnamon, and salt until smooth and well combined. -
Assemble
Pour the custard evenly over the bread. Gently press the bread down so it absorbs the liquid. -
Add Butter
Drizzle the melted butter evenly over the top. -
Rest
Let the casserole sit for 10 minutes to allow the bread to fully soak up the custard. -
Bake
Bake uncovered for 40 minutes, or until the top is golden brown and the center is set. -
Serve
Let cool slightly before serving. Enjoy warm.
Notes
-
Best bread choice: Brioche and challah give the richest, softest texture, while French bread creates slightly firmer edges.
-
Day-old bread works best: Slightly stale bread absorbs the custard without becoming soggy.
-
Make it ahead: Assemble the night before, cover, refrigerate, and bake in the morning.
-
Extra flavor: Add a pinch of nutmeg or swap half the milk for heavy cream for a richer casserole.
-
Serving ideas: Top with maple syrup, powdered sugar, fresh berries, or whipped cream.
