Creating your French Toast Casserole is simple with these straightforward steps:

1. Prep the Bread: Cut the loaf into 1-inch cubes and place them in a greased 9×13-inch baking dish.
2. Mix the Custard: In a large mixing bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until fully combined.
3. Combine Mixtures: Pour the custard mixture evenly over the bread cubes, ensuring all pieces are soaked.
4. Refrigerate: Cover the baking dish with plastic wrap and refrigerate for at least 1 hour (or overnight for an even richer flavor).
5. Preheat Oven: When ready to bake, preheat your oven to 350°F (175°C).
6. Bake: Remove the plastic wrap and bake the casserole for 45-50 minutes, or until the top is golden and the custard is set.
7. Rest: Let the casserole rest for about 10 minutes before slicing.
8. Serve: Drizzle individual portions with maple syrup and sprinkle with powdered sugar and fresh fruit if desired.

These step-by-step instructions will lead you to your delicious, fluffy French Toast Casserole that everyone will love!
