This was easy to make and everyone loved it.
12 slices of bread (I used store brand white bread as that's what was leftover)
1 stick of butter
5 large eggs
3/4 cup brown sugar
1 large teaspoon cinnamon
1 1/2 cups milk (I used non fat)
Melt the butter in the casserole dish. You can do this either in the oven or in the microwave. Mix together the brown sugar and the cinnamon. Cover the bottom of the casserole dish with six of the slices of bread. Because I was using white bread, I was able to make it fit very nicely. Sprinkle half of the brown sugar/cinnamon mixture over the bread. Place the remaining six slices of bread on top. In a small bowl mix together the eggs and the milk. Pour the egg mixture over the bread. I went slowly allowing the bread to begin to soak up the egg mixture. Sprinkle the remaining brown sugar/cinnamon mixture on top. Cover with foil and refrigerate several hours. I had this in the refrigerator over night.
In the morning, preheat the oven to 350 degrees. Keep the casserole covered and cook for thirty minutes. Uncover and cook an additional fifteen minutes. I then kept the casserole in the turned off oven for another fifteen minutes while I got ready for work.
I brought maple syrup with me. I saw a few people pour warm syrup on the french toast. It's very sweet and so I ate it without syrup.
