French Toast Casserole

Butter for greasing the pan
1 loaf Challah bread in 1-inch slices, any kind will do
2 cups whole milk (3 if letting sit overnight)
3 eggs
2 tbsp sugar
1/2 teaspoon salt
1 tsp vanilla (optional)
3 tbsp liquer of your choice (optional)
1/4 cup raisins or almonds (optional)
1/4 tsp cinnamon
1 - 2 tbsp butter

1. Generously grease a 9×13-inch baking dish with butter.


2. Arrange bread in two tightly-packed layers in the pan. Cut one slice into smaller pieces to fill in gaps. If you are using any fillings of fruit or nuts, this is the time to get them between the layers or sprinkled atop.


3. Whisk milk, eggs, sugar, salt, vanilla or liqueur and pour over the bread. Sprinkle with cinnamon and sugar and dot with butter. Wrap tightly with plastic wrap and refrigerate. The bread will absorb all of the milk custard while you sleep.


4. Bake at 425 for 30 minutes, or until puffed and golden.


5. Cut into generous squares and serve with maple syrup.
