French Toast Casserole Masterclass: Make Ahead u0026amp; Perfect Every Time!

Prep the pan: Grease a 9×13-inch baking dish with butter. Add the bread cubes in an even layer.

Make custard: In a large bowl, whisk eggs, milk, cream, granulated sugar, brown sugar, vanilla, cinnamon, nutmeg, and salt until smooth.

Combine: Pour custard evenly over the bread. Gently press to help the bread absorb liquid.

Streusel (optional): Mix flour, brown sugar, cinnamon, and salt. Cut in cold butter until crumbly; chill.

Bake: Preheat oven to 175°C/350°F. Scatter streusel over the casserole (if using). Bake uncovered 40–50 minutes, until puffed, set in the center, and golden on top (a knife should emerge without wet custard).

Finish u0026 serve: Rest 10 minutes. Dust with powdered sugar and serve warm with maple syrup and berries.
