Melt 1 stick of butter in a glass 9x13 baking dish in the microwave.
Generously sprinkle the pan with brown sugar. Sprinkle with a bit of cinnamon and nutmeg.
Fill the pan with thick slices of Italian bread. Pack them in tightly.
Beat 3 eggs, 1 1/4 cup milk, 1 tsp vanilla.
Pour egg mixture over bread, making sure the tops of every piece is wet. The pan will have egg mixture sitting in the bottom.
Cover and chill overnight.
Remove from fridge for 30 minutes before baking.
Preheat oven to 350.
Bake until the sugar is bubbly and the top of the bread is dry. About 40 minutes or so.
Serve immediately. Place with the sticky side up on a plate.
