Slice bread and arrange slices in a generously buttered 9 by 13-inch flat baking dish in 2 rows, overlapping the slices.
In a large bowl, combine the eggs, half-and-half, milk, sugar, vanilla, cinnamon and nutmeg and beat with whisk. Pour mixture over the bread slices, making sure all are covered evenly with the mixture. Spoon some of the mixture in between the slices. Cover and refrigerate overnight.
Spread Praline Topping evenly over the bread and bake for 40 minutes, until puffed and lightly golden. Serve with maple syrup.
