How to Make French Toast Casserole
Step 1: Preheat the Oven
Preheat your oven to 425 degrees. While the oven heats up, butter a 13x9 inch baking pan and set it aside.
Step 2: Make the Brown Sugar Mixture
In a small saucepan, melt the butter over medium heat. Once the butter is melted, stir in the brown sugar until dissolved and smooth. Pour this mixture into the bottom of the prepared baking pan and spread it evenly.
Step 3: Add the Bread Cubes
Spread the bread cubes evenly over the brown sugar mixture in the pan. Ensure that they cover the mixture completely.
Step 4: Whisk the Egg Mixture
In a medium-sized bowl, whisk together the eggs, milk, vanilla extract, and 1 teaspoon of cinnamon. Pour this egg mixture over the bread cubes, making sure every piece is saturated.
Step 5: Sprinkle Toppings
Sprinkle the remaining teaspoon of cinnamon and the tablespoon of brown sugar over the top of the bread mixture to create a sweet crust.
Step 6: Bake the Casserole
Place the baking pan in the preheated oven and bake for 25-30 minutes. The casserole should be golden brown on top and slightly puffed.
Step 7: Serve and Enjoy
Remove the casserole from the oven. If desired, dust with powdered sugar before serving. Enjoy your delicious French toast casserole!

Pro Tips from My Kitchen
✓ Use Day-Old Bread – Day-old French bread absorbs the egg mixture better, resulting in a creamier texture. Fresh bread can make the casserole soggy.
✓ Mix Up the Spices – Feel free to add nutmeg or allspice along with cinnamon. This can elevate the flavor and give a unique twist to your casserole.
✓ Let It Soak – After pouring the egg mixture over the bread, let it soak for at least 30 minutes. If possible, cover it and refrigerate overnight for the best flavor.
✓ Check for Doneness – Oven temperatures can vary. Check the casserole while baking; it should be set in the middle and golden on top. If it browns too fast, cover it loosely with foil.
✓ Serve Warm – For the best experience, serve the casserole warm. It pairs wonderfully with maple syrup, fresh fruit, or whipped cream.
