Creating this incredible French Toast Bake is easy when you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Bread: Cut the loaf of bread into 1-inch cubes. Place the cubes in a large mixing bowl or a greased 9×13 inch baking dish.
3. Make the Custard Mixture: In another bowl, whisk together the eggs, milk, granulated sugar, vanilla extract, ground cinnamon, nutmeg, and salt.
4. Combine Mixtures: Pour the custard mixture over the bread cubes and gently toss until all the bread is coated.
5. Rest: If time allows, cover the dish with foil and let it sit in the refrigerator for at least 30 minutes to overnight. This allows the bread to absorb the custard fully.
6. Bake: Remove the dish from the refrigerator and uncover it. Bake in the preheated oven for 40-45 minutes, or until golden brown and set in the center.
7. Cool: Allow the French Toast Bake to cool slightly for about 10-15 minutes before serving.
8. Serve: Drizzle maple syrup over the warm casserole and add fresh berries if desired.

This straightforward process will lead you to a delicious French Toast Bake that your family and guests will love!
