1-First Step: Preheat and Prepare the Pan Begin by preheating your oven to 425 degrees Fahrenheit to get it ready for baking. Next, butter a 13×9 inch baking pan to prevent sticking and add a subtle richness to the base of your casserole.

2-Second Step: Create the Bottom Layer In a small saucepan, melt ½ cup butter over medium heat until it’s fully liquid. Stir in 1 cup packed brown sugar until it’s dissolved and smooth, creating a caramel-like mixture. Pour this evenly into the prepared baking pan as the bottom layer for a sweet surprise in every bite.

3-Third Step: Add the Bread Take your ½ loaf of French bread, cut it into cubes (about 8 oz total), and spread them evenly over the brown sugar and butter layer. This step ensures the bread soaks up the flavors beautifully without becoming too soggy.

4-Fourth Step: Mix the Custard In a medium bowl, whisk together 6 eggs, 2 cups milk, 2 teaspoons vanilla extract, and 1 teaspoon of the cinnamon until well combined. This mixture forms the heart of the casserole, providing moisture and binding everything together.

5-Fifth Step: Assemble and Soak Pour the egg mixture over the bread cubes, making sure all pieces are fully saturated for even cooking. Let it sit for a moment to absorb, which helps achieve that perfect custardy texture.

6-Sixth Step: Add Toppings and Bake Sprinkle the remaining 1 teaspoon cinnamon and 1 tablespoon brown sugar over the top for extra flavor and crunch. Bake in the preheated oven for 25 to 30 minutes until the top turns golden brown and the center is set.

7-Final Step: Finish and Serve Remove the casserole from the oven and let it cool slightly. Sprinkle with powdered sugar if desired for a nice finish, then serve warm. This step allows the flavors to settle, making it easier to slice and enjoy with family or friends.
