Step‑by‑Step Instructions for Delicious French Toast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (177°C). This is crucial for achieving that perfect golden-brown crust on your French Toast Casserole. Make sure your oven is fully heated before placing the dish inside, which helps ensure even cooking throughout.
Step 2: Prepare the Baking Dish
Grease a 9×13-inch baking dish generously with unsalted butter or nonstick spray. This step prevents sticking and promotes that beautiful, crisp top layer. Set the dish aside as you move on to preparing the bread, ensuring it’s ready for the delightful custard mixture.
Step 3: Cut the Bread
Take your choice of brioche, challah, or French bread and cut it into 1-inch cubes. Spread the cubes evenly across the bottom of the greased baking dish. Aim for an even layer to allow the custard to soak in thoroughly and provide a consistent texture throughout the French Toast Casserole.
Step 4: Mix the Custard
In a large mixing bowl, whisk together 6 large eggs, 2 cups of whole milk, 1/2 cup of granulated sugar, 1 tablespoon of vanilla extract, 1 teaspoon of ground cinnamon, and 1/4 teaspoon of salt. Blend until the mixture is smooth and well-combined, creating a rich custard that will infuse the bread.
Step 5: Soak the Bread
Pour the custard mixture evenly over the bread cubes in the baking dish. Using your hands or a spatula, gently press the bread down to ensure each piece is soaked with the custard. This step is vital for achieving that soft, custardy center that makes this casserole so delicious.
Step 6: Add Butter
Drizzle 1/2 cup of melted unsalted butter evenly over the top of the bread and custard mixture. This adds a rich flavor and helps create a crispy topping as the casserole bakes, promising a satisfying contrast between the layers in your French Toast Casserole.
Step 7: Allow to Rest
Let the assembled casserole sit for about 10 minutes at room temperature. This resting time allows the bread to absorb the custard fully, ensuring every bite is infused with flavor and that perfect texture.
Step 8: Bake the Casserole
Place the baking dish in your preheated oven and bake uncovered for about 40 minutes. You’ll know it’s done when the top is golden brown and the custard has set—your kitchen will be filled with tantalizing aromas as it bakes.
Step 9: Cool and Serve
Once baked, remove the French Toast Casserole from the oven and let it cool slightly for about 5 to 10 minutes. This helps it set further for easier slicing. Serve warm, topped with maple syrup or fresh berries for a delightful finish to your comforting morning dish.

Make Ahead Options
These French Toast Casserole options are perfect for busy home cooks who want to save time without sacrificing flavor! You can prepare the casserole up to 24 hours in advance by following a few simple steps. First, assemble the casserole and cover it with plastic wrap before refrigerating after soaking the bread. This allows the custard to infuse the bread overnight, ensuring it’s just as delicious the next morning. When you’re ready to bake, simply remove the plastic wrap and pop it into the oven for about 40 minutes. Keep in mind that allowing it to rest for about 10 minutes after baking will enhance its texture and flavor. Enjoy the convenience of a make-ahead meal that effortlessly feeds loved ones during busy mornings!
