My mom made something similar to this on Christmas morning. It was really good, and when looking through some other receipes for stuff like it I found this. This morning a friend of mine had a kind of pot luck brunch and had people bring stuff over. This was perfect (and it came out soooo good).

French Toast Casserole

Ingredients:
1 loaf French bread or Challah
8 large eggs
3 cups whole milk
4 teaspoons sugar
1 teaspoon vanilla
1/4 teaspoon each cinnamon and nutmeg

Topping:
2 sticks butter
1 cup light brown sugar
1 cup chopped pecans (optional)
2 tablespoons corn syrup (or maple syrup)
1 teaspoon cinnamon
1/2 teaspoon nutmeg

Grease a 13 by 9 inch pan. Cut bread into 1 inch thick slices and arrange in baking dish, overlapping slices to fit, if necessary.
Combine eggs, milk, sugar and vanilla and spices until blended.
Pour mixture over bread, making all is covered evenly. Cover pan with foil and refrigerate overnight.
When ready to bake, preheat oven to 350.
Spread topping evenly over bread and bake, uncovered, for 40 - 50 minutes, or until puffy and lightly browned.
Can serve with additional maple syrup and bacon or sausage.

Variations: Could also sprinkle the top of the casserole with blueberries before baking or just sprinkle cinnamon sugar over the top instead of the topping

Yum. I have a tiny bit leftover too that I think I will have right now.
