Creating the French Toast & Preserves Casserole is simple when you follow these clear steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or cooking spray.
2. Prepare the Bread: Place the cubed French bread evenly in the greased baking dish.
3. Make the Egg Mixture: In a large bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.
4. Combine Mixtures: Pour the egg mixture over the cubed bread, ensuring all the pieces are soaked. Gently press down to help the bread absorb the liquid.
5. Add Preserves: Drop spoonfuls of your chosen fruit preserves over the top of the soaked bread. Use a knife to swirl the preserves gently into the mixture for an even distribution.
6. Let It Soak: If time allows, cover the dish with plastic wrap and let it soak in the refrigerator for at least 30 minutes or overnight for the best results.
7. Bake: Remove the plastic wrap and bake the casserole in the preheated oven for 45-50 minutes, or until the top is golden brown and the center is set.
8. Cool Slightly: Once baked, remove the casserole from the oven and let it cool for about 10 minutes before serving.
9. Dust with Powdered Sugar: For a finishing touch, dust the top with powdered sugar if desired.

These straightforward steps will guide you in creating an amazing French Toast & Preserves Casserole that will impress everyone at your breakfast table!
