1lbloaf french bread, cut into 1 inch cubes (about 10 cups)
For the topping:
2tablespoonsunsalted butter, cut into small cubes
3tablespoons granulated sugar
To serve: maple syrup
Place the bread in a greased 13x9 inch baking dish.
In a large bowl, whisk together the eggs, milk, 1 tablespoon granulated sugar, salt, and vanilla extract. Pour the mixture over the bread cubes.
Press the bread cubes lightly with your hands so that they soak up the vanilla custard.
Cover and refrigerate overnight (or for at least two hours).
When you're ready to bake the casserole, preheat the oven to 350°F.
Uncover and dot the casserole with the butter cubes, then sprinkle with cinnamon sugar.
Bake for 45–50 minutes, or until the top is golden brown and the custard is set.
Let stand for 5 minutes, then cut into slices and serve with maple syrup.
Want to add mix-ins? Add half of a cup of chocolate chips or 1 cup of fresh fruit (like blueberries or sliced strawberries) along with the bread. Pour the custard over the top and proceed as directed in the recipe above.
