How To Make Brioche French Toast Casserole

1. Prep work: Cut the brioche bread into 1-inch cubes and grease a 9-inch baking dish with cooking spray. Add the cubed bread slices to the prepared baking dish and spread it out evenly. 

2. Make the batter: In a large bowl, whisk the eggs together with the milk, heavy cream, brown sugar, and cinnamon. Pour the egg mixture evenly over the bread, and let the bread soak for 30 minutes. 

3. Make the topping: When the bread is almost done soaking, preheat the oven to 350°F (180°C). Add all the brown sugar, butter, flour, and cinnamon to a large bowl. Work these ingredients together with your fingers until they combine into coarse crumbs. 

4. Bake the casserole: Sprinkle the topping evenly over the soaked bread. Bake the casserole covered for 20 minutes. Remove the foil and bake for another 30-35 minutes until golden brown.

5. Serve: Let the baked casserole cool for about 10 minutes before slicing and serving. Serve with maple syrup and any other desired toppings you want, and enjoy!
