Overnight French Toast Casserole

Overnight French Toast Casserole uses cubed brioche bread soaked in a mixture of eggs, whole milk, melted butter, vanilla, cinnamon, brown sugar, and salt, then baked with a streusel-like oat topping. The brioche absorbs the custard overnight, resulting in a rich, tender interior topped with a sweet, crumbly mixture that adds texture and warmth.

Description

This Overnight French Toast Casserole combines cubed brioche bread with a custard mixture made from beaten eggs, whole milk, melted butter, vanilla extract, cinnamon, brown sugar, and a pinch of salt. The bread soaks in this mixture for at least four hours or overnight, allowing the custard to penetrate and soften the bread chunks thoroughly.

The topping is prepared separately by combining flour, brown sugar, cinnamon, salt, cold cubed butter, and rolled oats to form small clumps that provide a crumbly texture after baking. This topping is chilled until ready for use.

Before baking, the casserole dish is buttered or sprayed, and the soaked bread is evenly spread within. Topping is applied on top, and the casserole is baked at 350°F until golden and set. This method yields a dish with a creamy center and a crunchy, oat-studded top layer. Additional butter and maple syrup can be served alongside for richness and sweetness.
