Cut bread into 1-inch thick slices and arrange tightly in single layer.
Beat eggs, then whisk in milk, 3 tablespoons of the sugar, vanilla and salt. Pour over bread.
Combine the remaining sugar and cinnamon.
Peel, core and thinly slice apples. Place half the apples over the bread. Sprinkle with cinnamon sugar mixture. Repeat a second time. Cover and refrigerate for at least an hour.
Cut butter in pads and arrange over apples. Bake uncovered for 30-35 minutes. Apples should be tender.
Notes
This is a great recipe to make the night before and bake in the morning.I use whatever apples I have on hand.
