Preheat your oven to 350°F (175°C).
Grease a 9x13 inch baking dish.
In a large bowl, whisk together the eggs, milk, sugar, vanilla, cinnamon, and salt.
Add the cubed bread to the egg mixture, stirring gently to combine.
Let the mixture sit for about 10 minutes to allow the bread to soak.
Pour the mixture into the prepared baking dish, spreading it evenly.
Cover with foil and bake for 30 minutes.
Remove the foil and bake for an additional 15 minutes, or until golden brown.
Allow to cool for a few minutes before serving.
Top with fresh berries, syrup, or powdered sugar as desired.
