French Toast Casserole is an easy-to-bake casserole with flavors of cinnamon, brown sugar and caramel. This is the best French toast casserole recipe you will ever find.
Preheat the oven to 425 degrees. Spray a 9 x 13 casserole dish lightly with cooking spray. Prep your French bread by cutting it into cubes and setting it aside.
Melt butter over low to medium heat in a sauce pan. Add in the brown sugar and mix until the sugar has dissolved. Do not overheat it, as it does not need to boil.
