Instructions
The Night Before
Butter the bottom and sides of a 9 by 13-ich casserole dish.
Slice the challah bread into 1 inch thick slices using a serrated bread knife. Arrange them in the casserole dish using a shingle pattern to overlap the slices slightly.
1 loaf challah bread
In a large bowl, whisk the eggs. Add in the milk, half-and-half, vanilla extract and cinnamon, and whisk to combine.
Pour the liquid mixture over the sliced bread in the casserole dish. Try to coat each slice.
Cover the dish and refrigerate overnight.
In the Morning
Approximataely one hour before you want to serve the casserole, preheat the oven to 350°F.
While the oven is preheating, melt the stick of butter on medium heat in a small saucepan. Add in the brown sugar and corn syrup. Stir frequently until the mixture is bubbling.
½ cup unsalted butter, 1 cup light brown sugar, 3 tbsp light corn syrup
Flip the slices of bread from front to back. Pour the butter and brown sugar mixture over the bread. Make sure to coat the exposed edges of the bread.
Bake in the oven uncovered for 40 minutes.
Remove from oven and let cool for 5 minutes before serving.
Notes
One loaf of oblong challah bread will yield 12-14 one-inch-thick slices. Plan on a serving size of 1 slice per person if you are serving other entrees, or 2 slices per person if the French toast is the only entree.
You do not need to "stale the bread" the way you do with traditional French toast made on a griddle. Instead, you can use fresh or slightly stale bread.
Cut the baked casserole with a spatula.
Store leftovers in a covered dish in the refrigerator.
Reheat leftovers in the microwave for one minute on high for one serving.
