• Granulated Sugar – Sweetens the mixture; consider reducing the amount for a lower sugar option.
• Ground Cinnamon – Adds warmth and spiciness; adjust according to personal taste and preferences.

Step‑by‑Step Instructions for French Toast Casserole
Step 1: Prepare the Egg Mixture
In a large mixing bowl, whisk together the large eggs, milk, heavy cream, granulated sugar, vanilla extract, and ground cinnamon until well combined. The mixture should be smooth and creamy, creating a delightful custard base for your French Toast Casserole. Set aside your well-mixed egg concoction while you gather and prepare your bread.
Step 2: Soak the Bread
Cut your chosen bread into 1-inch squares, ensuring a soft and fluffy texture. Toss the bread cubes in the egg mixture until they are all fully soaked and coated, allowing each bite to be infused with flavor. Cover the bowl with plastic wrap and refrigerate for at least 3 hours or overnight to ensure the bread absorbs the custard mixture thoroughly.
Step 3: Preheat Oven
When you’re ready to bake, preheat your oven to 350°F (175°C). This temperature will ensure that your French Toast Casserole cooks evenly and achieves that perfect golden-brown top. Preparing your oven ahead of time will help shorten the baking process and deliver a warm, comforting dish right on schedule.
Step 4: Make the Topping
In a small bowl, combine all-purpose flour, brown sugar, ground cinnamon, and salt. Use a pastry cutter or your fingers to cut in the butter, mixing until the mixture resembles coarse crumbs or sand. This crumbly topping will add a delightful texture to your French Toast Casserole and create a sweet, crispy layer on top after baking.
Step 5: Assemble Casserole
Grease a 9×13-inch casserole dish with butter or cooking spray to prevent sticking. Spoon the soaked bread mixture evenly into the prepared dish, spreading it out to make sure everything bakes evenly. Sprinkle your prepared topping generously over the bread mixture, ensuring an even distribution for that deliciously crunchy finish.
Step 6: Bake
Place your assembled French Toast Casserole in the preheated oven and bake for 50 minutes. You’ll know it’s ready when the top is golden brown and the center is set and no longer jiggles. The enticing aroma of vanilla and cinnamon will fill your kitchen, luring everyone to the breakfast table.
Step 7: Glaze & Serve
Once the French Toast Casserole is baked to perfection, remove it from the oven and let it cool slightly. Drizzle with a sweet glaze made from powdered sugar and a splash of milk for a delightful finishing touch. Serve warm and enjoy smiles all around as everyone indulges in this heartwarming breakfast treat!
