It's like dessert for breakfast... delicious vanilla flavor, bananas, and a smooth, buttery brown sugar sauce all tied into these decadent Overnight Bananas Foster French Toast.
Spray a 13 x 9-inch casserole dish lightly with cooking spray.
Layer the bread slices on the bottom of the dish, slight overlap is okay, but it's better to kinda squish them all together in there.
In a large bowl whisk together the eggs, milk, vanilla extract, the cinnamon, white sugar and salt until combined and pour the whole mixture evenly over the bread.
Cover the dish with foil and refrigerate overnight or at least 6-8 hours.
When you're ready to bake it:
Bring the french toast to room temp, by taking it out of the fridge and uncovering it for at least 30 minutes or so before baking.
Preheat your oven to 350° F.
Bake the dish uncovered on the middle rack until golden, about 40 minutes or so.
About 10 minutes before it is ready, melt butter on the stovetop on low heat.
Add the brown sugar, cinnamon and vanilla and stir until sugar is dissolved.
Simmer for 2 minutes.
Add the sliced bananas and remove from heat. Keep warm and covered until the french toast is ready.
Once the french toast is cooked, serve on plates topped with the bananas and sauce.
