Creating the perfect Creme Brulee French Toast Casserole is easier than you think! Just follow these steps:

1. Prepare the Baking Dish: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter.
2. Cubing the Bread: In a large bowl, place the bread cubes and set aside.
3. Make the Custard: In another bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.
4. Combine: Pour the custard mixture over the bread cubes. Gently toss until all the bread is soaked.
5. Refrigerate: Cover the dish with plastic wrap and place it in the refrigerator for at least 4 hours, preferably overnight.
6. Bake: Once ready to bake, remove the dish from the fridge. Sprinkle the brown sugar evenly over the top. Bake in the preheated oven for 45 minutes until golden brown and puffed.
7. Caramelize (Optional): For a more authentic crème brûlée flavor, you can use a kitchen torch to caramelize the sugar on top for a couple of minutes until it is bubbly and golden.
8. Let it Cool: Allow the casserole to cool for about 10 minutes before serving for easier slicing.

These simple steps will ensure your casserole is prepared with excellence!
