Notes

Be sure to let this french toast casserole brioche rest for a minimum of 30 minutes before baking.
To make this overnight brioche french toast bake, make the recipe following the instructions like normal. Then, stick the baking dish in the fridge covered in aluminum foil or a plastic wrap alternative. Just before baking, top with the butter pieces and sugar.
Tweak the seasonings to make this French toast casserole recipe your own! Replace vanilla extract with cardamom extract or cinnamon extract, etc. Instead of cinnamon, use Chinese five spice or apple pie spice!
Prefer to make this in individual servings, Butter some ramekins and bake them until fully cooked (165 degrees F).
Instead of cubes, you can cut the loaf of bread into slices and layer them together.
The best French toast comes from stale bread. Make any bread "stale" by baking the cubes on a baking sheet at 350 degrees for 10-20 minutes, stirring halfway.
No brioche? Try French bread, sourdough, or really almost any other type of bread. To highlight the flavors in the custard, stick with a neutral-tasting bread.
Feel free to skip the cream and use half and half or more whole milk.
To make it easier to toss the brioche cubes in the mixture of milk and egg, you can add everything to a large mixing bowl, stir, then place it all in the casserole dish.
